Jay you should have used engine paint designed for high tempratures as they usually have matalic particals in the paint suspension so it would act less like an insulator
@@radicalxedward8047 that's very true. But at the same time I'm pretty sure the heat pipes aren't quite as efficient (not to mention tim) so even though it's that good at transfering heat it'll be limited by the wicks,heatpipes and the phase changing. Which kind of make me doubts it'll make that much of a difference considering.

3-6c increase depends on thickness of paint. Also you can use Engine paint as it is a ceramic paint that will help reduce insulation compared to normal spray paint.

I'd still recommend against painting your cooler for at least four reasons. 1. Paint takes space, and less space gets clogged with dust easier and it's a pain to clean. 2. The performance of your heatsink will deteriorate as it accumulates dust, so you will have to clean it more often. 3. Why not just get a black one with proper coating? 4. Black is good for radiating heat, but other colors might decrease the efficiency of the cooler even more.

If you spray paint a fine mesh you will definitely decrease the hole÷mesh ratio, therefor decreasing flowrate. If it's a courser mesh, a thin paint shouldn't be an issue
It's about surface area as long as the mass can keep it coming. Small snips in the fins adds surface area. As long as air flow is not impeded grind the fin stacks and use aluminum washers to thin shim more find :-/ Many of these kits don't like to work as hard.... you need a larger bladed fan not the sexy S blades.

I'm right with you on this. I predict it will have a noticeable impact on cooling performance. Cheap spray paint definitely and a good air spray job maybe less. Let's see!
Something that would be interesting to see is how big of an impact a partial coverage of paint would impact performance. Like painting the most visible areas and leaving as much metal exposed as possible.
Spraying an intercooler black makes an improvement. I guess with higher temps from a CPU cooler it makes more of a difference. Mighty Car Mods was the whole spray intercoolers black.
A dark / black surfaces makes for a better radiator, so that's probably why. But it's a tradeoff - paint also adds thickness and the paint is less thermally conductive, so there's just a lot of variables. But there are better ways to make really thin coatings using other means (other than paint), that will help improve the emissivity of the surface. The lower the heat load, the less the extra thickness of the coating matters - because the heat has more time to diffuse through the material.
Noctua had mentioned that they were having trouble finding a color compound that would give them the performance they were looking for and that they could use to "color" their heatsinks, because of the results jay gave and I think they know what they were doing. 3 degrees does not seem like much, but if we multiply it by the time of use it becomes something VERY SERIOUS to consider.
paused when he asked for predictions, im guessing +5C edit: wow only 1-3C, im surprised, thats the same margin as ok tim vs premium tim. i would have thought a coat of paint on all the fins would do more.
The answer is simply yes. You are adding a layer with a lower conductivity this adding to the thermal resistance. This also depends on the layer of thickness.
This was kind of neat, Might Car Mods and Engineering Explained covered this kind of topic regarding intercoolers and rads. If I remember right, the conclusion was that absolute thermal efficiency was hurt, but because black paint is more thermally emissive that passive temps were unchanged or better.
A very little bit! The heat can still travel up the pipes, and radiate out the joints to the fins. The paint will insulate it a small amount but as long as airflow is not blocked, it should be quite minimal.
I use radiator spray for radiators to heat the house. Inside of them runs really hot water, sometimes so hot the radiator can burn your fingers if you touch it. So it needs the special heat resistant spray. I have a Scythe Mugen 5 PCGH (Mugen 5 rev.B Dual fan edition) and the radiator is silver and it stick out a lot in my PC case which is all black components and glass side. I wanted it to spray with matte black color, but only the very first fin you see, not the other 30 fins. Purely for aesthetics. I used a random matte black spray for 5$ (400ml) like a no name unknown brand and it worked nicely. 0 changes to temps as only the 1st fin nearest to the glass side panel was sprayed. ALL YOU NEED TO PAY ATTENTION TO IS HOW YOU SPRAY!!!!! You need to spray in parts, slowly, from a distance of at least 25/30cm, or you will get running drops of paint. Ofc you spray it disassembled from the case with no component even near that shit!!! I covered the rest of the fins with paper and tape. Only the front fin was visible. You want to spray from top to bottom - your hand is above the cooler, not next to it - you avoid the drops better. But really you need the 25cm and spray like pst pst pst pst from side to side, left right, right left etc... and not pssssssssssssssssst in one place or YOU ARE FUCKED!!!!
I agree. Pre commercial (1:32) that there will be a minimal temp difference. There will be some blockage from the layer of paint therefore hindering air flow so there will be a slight difference. (post test) I guess I was wrong. I would consider it more than slight but for an average user it wouldn't make enough difference to not do it.
Black colours are meant to disapate heat up to 10x faster than white or shiny. Obviously that is negated by the insulation of the paint, but I wonder if it was anodized black it may see an improvement. Would love to see a video on it @JayzTwoCents
Well I know white spray paint is thermally conductive thanks to being made out of titanium dioxide. Then some specialized black spray paint is carbon so its super conductive. But I just cant find any information on ordinary black spray paint..
I like how your videos (such as this one) aim to answer questions that I've been asking myself! I predict that painting it black, assuming the coat of paint is thin, would improve temperature exchange due to physics (black body radiation) and was looking to see if it'd be worth painting the Noctua NH-D15 black.
@@maxbroughton2216 my custom builds is the name of the video, also it had less views then his average. So it doesn't seem like it fits the majority of the audience, just to out that out there.
Reminds me of the time when fixing up an SUV we bought at an auction, someone went ahead and painted the intercooler fins black. Not only that, he used a paintbrush so the thin aluminum got squashed flat. The only thing in that SUV that was in perfect condition, and they destroyed it.
Right on time. I was about to buy NH D15 and spray paint it to be pink. (just joking about the pink) Glad to know it won't impact cooling all that much. :D

I remember a similar test with cars that were turbocharged back in the late 90’s - especially with Honda’s- painting their intercoolers black to be more stealthy. The same result happened. In real world data logging the temperature difference was negligible. In dyno testing and doing repeated back to back runs with no cooldown, there was a significant difference in temps. Physics doesn’t lie. Will you see a change? Yes. Is it worth doing now that you know what the impact is? That is entirely up to you to decide.
Commenting at 1:42 I have been a professional auto and industrial painter for over 25 years. It depends on what paint you use. Most cans of spray paint (bomb can) is Enamel and it happens to spray thick, at least you have to spray the thinned out garbage in that can, thick, to get proper coverage. (people start with a tack coat wait three min. and then spray a couple more light coats. Then one to two medium wet coats to get a nice finish its not a race to get the paint to cover in one coat) Enamel will have different heat dissipating properties than Lacquer as Enamel will hold in the heat like your stove in your kitchen. Most kitchen appliances are coated with Enamel because it has great thermal properties. This leads into the next paint in cans (bomb can). Lacquer takes less to cover and would have better heat dissipating attributes than Enamel. It takes Lacquer only a few coats to cover and less paint millage means better heat reduction, but, Lacquer cost more money. So what kind of paint did you use??? Now you got your paint lesson, I don't think it's going to make a huge difference being it is only 100 degrees at best. You might have a few degree uptake with a painted one depending on what material was used and depends on how much was applied. Now you can get ceramic paint and yes ceramic dissipates heat well but it is still going to fall in the Enamel, Lacquer or Urethane category. (yes I know I did not mention Urethane because it is usually a two part mix and only a few versions of it is in a can (bomb can). Alsa corp. makes a clearcoat Urethane in a can and it is a one time use. You pop the bottom of the can releasing the activator and start spraying a 2K clear like your car is painted with in a can. (1K means no activator just open and spray with a spray gun or shake and spray in a can (bomb can). Not really applicable in this situation. So I say 5 degree at best without seeing how much was applied. If Jay is heavy handed I can see a uptick in temp and if he is light handed a down tick in temp.
Edit: If the paint is applied heavy, like, really thick of course it's going to have an effect on heat dispersion (typed at 2:00 into video) I am a light painter and would if I paint it, use three to four very light coats of coverage. The last coat being my beauty coat. Paint that is applied thick blocking the fins does not allow for cooling to take place. After watching this if I think it was applied way to thick I have a cooler like this and I will do the test myself painted by a professional. I can spray paint from a bomb can and you cannot tell it was from a bomb can.
@@CrashM85 an enamel based paint is usually used on engines and are engineered in order to not insulate heat. Either cemaric or sometimes metal flakes is usually mixed in with it the paint. It comes in rattle cans as well, i painted some chipset heatsinks with it before, a non issue. But thermal volume is negligible enough that it doesn't matter if you ran it bare with most pch chips (south bridge, north bridge etc etc)
Anodised aluminium is surface is aluminium oxide. Which is in turn technically a ceramic, even though people don't usually call it that way. So they're misleading, but not wrong. Anyway that's what beQuiet themselves call the black surface, probably because they had to to reduce the cost after doing black chrome for a while, while not making it sound too pedestrian.
@@SianaGearz Erhm no.... Ceramic coating is a real thing and it's used for all metals. Ex the cookware in your kitchen are a likely place you could find some ceramic coated metal If BeQuiet have called it ceramic coating it's because they keep making "creative" marketing, like they always have done a bit
@@SianaGearz Here, this was literally the "i'm feeling lucky" google result after typing in ceramic coated metal. I've been a pro-metal worker for decades now. Please use google next time before you claim someone els is lying: • Plasma Spraying: In plasma spraying, ceramic powder is passed through an ionized gas at extremely high temperatures, sometimes approaching 30,000 degrees (F). The pressurized gas speeds molten ceramic particles toward the substrate where they bond onto its surface. The result is a strongly-adhering and high-density coating, but the process can be very expensive. • Detonation Gun: The detonation gun process is most effective for particular ceramic materials, such a tungsten carbide, that are required for producing highly dense coatings on a metal surface. It creates an explosion of oxygen and acetylene gas at around 6,000 degrees (F), melting the ceramic and firing it at high speed toward the target substrate. • Oxygen Acetylene Powder: This method involves heating ceramic powder under a 5000 degree (F) flame, and using compressed gas to spray the coating onto the substrate. It creates porous coating layers with relatively low adhesion strength. • Oxygen Acetylene Rod: In this method, a fused ceramic rod is passed under an oxyacetylene torch burning at 500 degrees (F). Pressurized gas is then used to spray molten ceramic material onto a surface, producing a coating with a high level of cohesive bonding.
@@VikingRul3s We're not actually at disagreement, even if i may have come across that way. This is misleading marketing, as i said. I don't have to google ceramic coatings for metal, i have been around long enough that i know what is generally meant, glass-like or clay-based coatings which is obviously not what beQuiet is doing. What i was aiming for is that it's not Jay's fault, he's just going by beQuiet's claims.
@@SianaGearz Ooh, my bad. Yeah, i didn't think Jay was doing it to mislead people. As you said, he's probably following what BeQuiet advertised. So i was merely correcting the obvious
@@shawnpitman876 Let's just take for example a clip of his old vs new temps he's displaying at 11:47. Painted temps when I hit this screenshot were (70+69+69+68+68+72+68+70+68)/9 [because package is at the top, plus 8 individual cores] = 69.1111 repeating. Phil's screenshot of the before temps were (69+69+66+63+62+60+63+66+66)/9 = 64.8888 repeating, or about 4.2C different. Admittedly higher than 3C, but I wouldn't say 'way more than' (unless you're going to argue the % diff)
@@ThineHolyBacon You clearly need to work on your reading comprehension. I didn't say the average of the cores, I said many of the cores jumped more than 3c, look at EACH CORE. 69 after to 69 before +0 69 after to 66 before +3 68 after to 63 before +5 68 after to 62 before +6 72 after to 60 before +12 68 after to 63 before +5 70 after to 66 before +4 68 after to 66 before. +2 Notice that MANY of the cores jumped MORE than 3c.
So, Ive done this test myself with a hyper 212 evo... or several... And what I found in my testing is that if you paint any tower cooler on a 45 degree downward angle where youre effectively NOT PAINTING the bottom of the plates, or even all the way thru the fins (because you only ever see if from the top DURR) what you are left with is a slick looking cooler and temp differences which are so low it can only be considered margin of error.
Prediction: It will matter a little bit, like 2-3 degrees. Edit: Seems like I was mostly right. Also It would be cool to see how the DIY solution compares to Noctua's black version of the cooler.
It really depends on the emissivity ratio of the heat sink being used. Thermodynamically speaking, in some cases painting the heat sink will have none to a very small effect upon its ability to dissipate the heat. In others, it can be devastating. It also depends on the type of paint being used. I would recommend anodizing a heat sink if you want to change the color of it.
I think yes! It will matter! I think a maximum of +5°c, which won't really be that much in the grand scheme of things. Edit: I was wrongish, but not very wrong so it was okay!
And Cinebench R20 is a "real wold test" also. It shows how heavy the CPU will get pushed for rendering and hard productivity work. By "realistic" he just meant for gamers while playing games only. Not sure why that is the only "real" use of a CPU.
@@mouaxiong8618 there are more cases like that than before, and also more cases with terrible airflow just for the looks. In both scenarios, the interaction between the case fans and the CPU heathsink is relevant
Mask the open areas of the finstack, paint the outside then unmask and paint pen the fin edges. there should be much less of a heat increase and you still get a good visual effect if you do a push pull setup as the exposed metal would mostly be hidden..
The thickness of the paint will obviously be the most important factor here. I doubt anyone would be surprised that the cooler won't work if you fill the area between the fins with paint. Spray paint however can be so thin the effect will be negligible.
It's not just ceramic. It's powder coated. It's a really thin fine layer. So the amount of insulation/cooling loss should be nonexistent or at the very least minimal.
dope. I'm considering painting a couple of subwoofers that I have, which use an aluminum speaker cover to radiate some of the heat from the rear of the driver which is buried deep inside the box (it's a folded horn). So it's good to know it will probably be fine - since I don't really plan on running them near their thermonuclear limits haha

Don’t judge JayZ - whatever wags his dog
The answer is simply yes. You are adding a layer with a lower conductivity this adding to the thermal resistance. This also depends on the layer of thickness.
This was kind of neat, Might Car Mods and Engineering Explained covered this kind of topic regarding intercoolers and rads. If I remember right, the conclusion was that absolute thermal efficiency was hurt, but because black paint is more thermally emissive that passive temps were unchanged or better.

wonder what his final word list for 2019 was...
I remember when I have found your channel, back then when I didn’t know English. Now it’s fun to watch your videos.
2am in uk and got notification for this, guess I’m staying up
Same, ballbagged but can't sleep.
Did the same. Tomorrow i will suffer for it.
ditto
A very little bit! The heat can still travel up the pipes, and radiate out the joints to the fins. The paint will insulate it a small amount but as long as airflow is not blocked, it should be quite minimal.
Noctua has started to make their stuff in black too. My 3800x runs decent temps with minor overclocking with its factory black NH-D15.
"there's games that'll peg a CPU while you're playing" c-can I be a CPU 😳
I love that Jay keeps a 5700 XT on his test bench. AMD GPU love!
because it overheats inside a case.
@Wischmopps no, it's a reference model which all overheat
Jay: The rattle can man.
that LTX '19 shirt during the integrated ad at 1:46 haha made my day
I use radiator spray for radiators to heat the house. Inside of them runs really hot water, sometimes so hot the radiator can burn your fingers if you touch it. So it needs the special heat resistant spray.
I have a Scythe Mugen 5 PCGH (Mugen 5 rev.B Dual fan edition) and the radiator is silver and it stick out a lot in my PC case which is all black components and glass side.
I wanted it to spray with matte black color, but only the very first fin you see, not the other 30 fins. Purely for aesthetics. I used a random matte black spray for 5$ (400ml) like a no name unknown brand and it worked nicely. 0 changes to temps as only the 1st fin nearest to the glass side panel was sprayed.
ALL YOU NEED TO PAY ATTENTION TO IS HOW YOU SPRAY!!!!!
You need to spray in parts, slowly, from a distance of at least 25/30cm, or you will get running drops of paint. Ofc you spray it disassembled from the case with no component even near that shit!!! I covered the rest of the fins with paper and tape. Only the front fin was visible. You want to spray from top to bottom - your hand is above the cooler, not next to it - you avoid the drops better. But really you need the 25cm and spray like pst pst pst pst from side to side, left right, right left etc... and not pssssssssssssssssst in one place or YOU ARE FUCKED!!!!

Maybe you could paint only the sides without the fins, since the others will be covered by fans? I guess the impact would be minimal.
I was hoping that the sponsor of this video was ifixit
I feel like mighty car mods did this a few years ago with car intercoolers

And they get 1 c different results. Being worse but conclusion was IT'S SAME!!!!
Dragan Crnogorac Are you angry with their conclusion?
eyyy I love mighty car mods
I agree. Pre commercial (1:32) that there will be a minimal temp difference. There will be some blockage from the layer of paint therefore hindering air flow so there will be a slight difference.
(post test) I guess I was wrong. I would consider it more than slight but for an average user it wouldn't make enough difference to not do it.
Black colours are meant to disapate heat up to 10x faster than white or shiny. Obviously that is negated by the insulation of the paint, but I wonder if it was anodized black it may see an improvement. Would love to see a video on it @JayzTwoCents
Well I know white spray paint is thermally conductive thanks to being made out of titanium dioxide. Then some specialized black spray paint is carbon so its super conductive. But I just cant find any information on ordinary black spray paint..

I like how your videos (such as this one) aim to answer questions that I've been asking myself! I predict that painting it black, assuming the coat of paint is thin, would improve temperature exchange due to physics (black body radiation) and was looking to see if it'd be worth painting the Noctua NH-D15 black.
You should do a yearly thing where you go over your favorite builds you did over the year
He's done that before, I can't remember if he did it for this year I think he did
Dennis Rigdon I think it would be awesome if he made it a yearly thing like how some TH-camrs make a best of
@@maxbroughton2216 my custom builds is the name of the video, also it had less views then his average. So it doesn't seem like it fits the majority of the audience, just to out that out there.
Reminds me of the time when fixing up an SUV we bought at an auction, someone went ahead and painted the intercooler fins black. Not only that, he used a paintbrush so the thin aluminum got squashed flat. The only thing in that SUV that was in perfect condition, and they destroyed it.
Right on time. I was about to buy NH D15 and spray paint it to be pink. (just joking about the pink)
Glad to know it won't impact cooling all that much.

As babyface Jay slowly fades away, a familiar friend returns~.
I've missed scruffy Jay.
I remember a similar test with cars that were turbocharged back in the late 90’s - especially with Honda’s- painting their intercoolers black to be more stealthy.
The same result happened. In real world data logging the temperature difference was negligible.
In dyno testing and doing repeated back to back runs with no cooldown, there was a significant difference in temps.
Physics doesn’t lie.
Will you see a change? Yes. Is it worth doing now that you know what the impact is? That is entirely up to you to decide.
Commenting at 1:42
I have been a professional auto and industrial painter for over 25 years. It depends on what paint you use. Most cans of spray paint (bomb can) is Enamel and it happens to spray thick, at least you have to spray the thinned out garbage in that can, thick, to get proper coverage. (people start with a tack coat wait three min. and then spray a couple more light coats. Then one to two medium wet coats to get a nice finish its not a race to get the paint to cover in one coat) Enamel will have different heat dissipating properties than Lacquer as Enamel will hold in the heat like your stove in your kitchen. Most kitchen appliances are coated with Enamel because it has great thermal properties. This leads into the next paint in cans (bomb can). Lacquer takes less to cover and would have better heat dissipating attributes than Enamel. It takes Lacquer only a few coats to cover and less paint millage means better heat reduction, but, Lacquer cost more money. So what kind of paint did you use???
Now you got your paint lesson, I don't think it's going to make a huge difference being it is only 100 degrees at best. You might have a few degree uptake with a painted one depending on what material was used and depends on how much was applied. Now you can get ceramic paint and yes ceramic dissipates heat well but it is still going to fall in the Enamel, Lacquer or Urethane category. (yes I know I did not mention Urethane because it is usually a two part mix and only a few versions of it is in a can (bomb can). Alsa corp. makes a clearcoat Urethane in a can and it is a one time use. You pop the bottom of the can releasing the activator and start spraying a 2K clear like your car is painted with in a can. (1K means no activator just open and spray with a spray gun or shake and spray in a can (bomb can). Not really applicable in this situation. So I say 5 degree at best without seeing how much was applied. If Jay is heavy handed I can see a uptick in temp and if he is light handed a down tick in temp.
Edit:
If the paint is applied heavy, like, really thick of course it's going to have an effect on heat dispersion (typed at 2:00 into video) I am a light painter and would if I paint it, use three to four very light coats of coverage. The last coat being my beauty coat. Paint that is applied thick blocking the fins does not allow for cooling to take place. After watching this if I think it was applied way to thick I have a cooler like this and I will do the test myself painted by a professional. I can spray paint from a bomb can and you cannot tell it was from a bomb can.
1:16 If you use an enamel paint which knowing you, probably. I'm betting that it's only going to make like a two to three c
Yupppppp
Maybe a Carbon Black paint... might rub off easily, but should be pretty conductive.
@@CrashM85 an enamel based paint is usually used on engines and are engineered in order to not insulate heat. Either cemaric or sometimes metal flakes is usually mixed in with it the paint. It comes in rattle cans as well, i painted some chipset heatsinks with it before, a non issue. But thermal volume is negligible enough that it doesn't matter if you ran it bare with most pch chips (south bridge, north bridge etc etc)
I'd imagine a powder coat would probably insulate it more~
Anyone else wondering why he removed the fixing $2500 dollar graphics card? I got to watch the whole vid and saw nothing wrong.
I watched it too...thought it was a great video.
I say it cools slightly worse mainly because of how large the heatsink is. And that Jay gets paint on himself.
I agree with your predictions, i think it'll make a few degrees difference but nothing crazy catastrophic
I sprayed the fins of a GSX-R750
in the early 2000s. Can't say I recommend painting something air-cooled.
Dude, that's a... bike. Works a bit differently from computers.
@@ZisisKoukoumakis durhhh I wonder why tards always reply to me lol.
The bike is also water-cooled and still overheated.
0:37 Nope, they are anodized or e-coated. Ceramic coating is for durability, way to expensive for a random styling "mod"
Anodised aluminium is surface is aluminium oxide. Which is in turn technically a ceramic, even though people don't usually call it that way.
So they're misleading, but not wrong. Anyway that's what beQuiet themselves call the black surface, probably because they had to to reduce the cost after doing black chrome for a while, while not making it sound too pedestrian.
@@SianaGearz Erhm no.... Ceramic coating is a real thing and it's used for all metals. Ex the cookware in your kitchen are a likely place you could find some ceramic coated metal
If BeQuiet have called it ceramic coating it's because they keep making "creative" marketing, like they always have done a bit
@@SianaGearz Here, this was literally the "i'm feeling lucky" google result after typing in ceramic coated metal. I've been a pro-metal worker for decades now. Please use google next time before you claim someone els is lying:
• Plasma Spraying: In plasma spraying, ceramic powder is passed through an ionized gas at extremely high temperatures, sometimes approaching 30,000 degrees (F). The pressurized gas speeds molten ceramic particles toward the substrate where they bond onto its surface. The result is a strongly-adhering and high-density coating, but the process can be very expensive.
• Detonation Gun: The detonation gun process is most effective for particular ceramic materials, such a tungsten carbide, that are required for producing highly dense coatings on a metal surface. It creates an explosion of oxygen and acetylene gas at around 6,000 degrees (F), melting the ceramic and firing it at high speed toward the target substrate.
• Oxygen Acetylene Powder: This method involves heating ceramic powder under a 5000 degree (F) flame, and using compressed gas to spray the coating onto the substrate. It creates porous coating layers with relatively low adhesion strength.
• Oxygen Acetylene Rod: In this method, a fused ceramic rod is passed under an oxyacetylene torch burning at 500 degrees (F). Pressurized gas is then used to spray molten ceramic material onto a surface, producing a coating with a high level of cohesive bonding.
@@VikingRul3s We're not actually at disagreement, even if i may have come across that way. This is misleading marketing, as i said.
I don't have to google ceramic coatings for metal, i have been around long enough that i know what is generally meant, glass-like or clay-based coatings which is obviously not what beQuiet is doing.
What i was aiming for is that it's not Jay's fault, he's just going by beQuiet's claims.
@@SianaGearz Ooh, my bad. Yeah, i didn't think Jay was doing it to mislead people. As you said, he's probably following what BeQuiet advertised. So i was merely correcting the obvious

1:20 - Prediction is +3C from being painted max
Post guess edit: Ayeeeee
Except you were wrong. Package temp is not the only temp that matters, and many of the cores jumped way more than 3c.
@@shawnpitman876 Let's just take for example a clip of his old vs new temps he's displaying at 11:47. Painted temps when I hit this screenshot were (70+69+69+68+68+72+68+70+68)/9 [because package is at the top, plus 8 individual cores] = 69.1111 repeating. Phil's screenshot of the before temps were (69+69+66+63+62+60+63+66+66)/9 = 64.8888 repeating, or about 4.2C different. Admittedly higher than 3C, but I wouldn't say 'way more than' (unless you're going to argue the % diff)
@@ThineHolyBacon I'd argue that highest temp is what counts, and that is 3°C worse in both tests.
@@ThineHolyBacon When talking about cooling performance, the average isn't what you want to be looking at

I'll get you next time, gadget. Next time.
So, Ive done this test myself with a hyper 212 evo... or several...
And what I found in my testing is that if you paint any tower cooler on a 45 degree downward angle where youre effectively NOT PAINTING the bottom of the plates, or even all the way thru the fins (because you only ever see if from the top DURR) what you are left with is a slick looking cooler and temp differences which are so low it can only be considered margin of error.
Jay, you should repeat this experiment using ceramic header paint instead of krylon fusion.
I just realized... he used celcius in spite being an American, Metric ftw!
I havent seen even one tech youtuber use anything other than Celcius. Its not about American or not, its the standard when its comes to tech. :)
Imperial is just metric with extra steps anyway...
@@shmaras tell that to NASA

let the water boiling at 100°
Prediction: It will matter a little bit, like 2-3 degrees.
Edit: Seems like I was mostly right. Also It would be cool to see how the DIY solution compares to Noctua's black version of the cooler.
I was really hoping they would do that
Prediction: Jay doesn't test a light coat between plain and heavy.
It really depends on the emissivity ratio of the heat sink being used. Thermodynamically speaking, in some cases painting the heat sink will have none to a very small effect upon its ability to dissipate the heat. In others, it can be devastating. It also depends on the type of paint being used. I would recommend anodizing a heat sink if you want to change the color of it.
I think yes! It will matter! I think a maximum of +5°c, which won't really be that much in the grand scheme of things.
Edit: I was wrongish, but not very wrong so it was okay!
"I want to do a *Real World Test*" and then proceeds to use an open test case, duh...
And Cinebench R20 is a "real wold test" also. It shows how heavy the CPU will get pushed for rendering and hard productivity work. By "realistic" he just meant for gamers while playing games only. Not sure why that is the only "real" use of a CPU.
Modern cases having massive airflows now I don't think it'll make a lot of difference.
@@mouaxiong8618 there are more cases like that than before, and also more cases with terrible airflow just for the looks. In both scenarios, the interaction between the case fans and the CPU heathsink is relevant
@@odinsplaygrounds Still the 99% of gamers or heavy users would have a closed case with proper case fans
I said the same thing. This test is pointless because of this.
Mask the open areas of the finstack, paint the outside then unmask and paint pen the fin edges. there should be much less of a heat increase and you still get a good visual effect if you do a push pull setup as the exposed metal would mostly be hidden..
It depends on the paint. Black Velvet does some cool-ing stuff. There are white papers on this subject all over the place.
If you go to an auto parts store, you can get ceramic spray paints in different colors. You would have to bake in the paint to cure it properly.
Would be nice to see the results with some electroplating. I think electroplating won't change any temp characteristics.
The thickness of the paint will obviously be the most important factor here. I doubt anyone would be surprised that the cooler won't work if you fill the area between the fins with paint. Spray paint however can be so thin the effect will be negligible.
how about trying to remove paint from a factory black heatsink?
It's not just ceramic. It's powder coated. It's a really thin fine layer. So the amount of insulation/cooling loss should be nonexistent or at the very least minimal.
dope. I'm considering painting a couple of subwoofers that I have, which use an aluminum speaker cover to radiate some of the heat from the rear of the driver which is buried deep inside the box (it's a folded horn). So it's good to know it will probably be fine - since I don't really plan on running them near their thermonuclear limits haha
Hi Jay. So it would be interesting to do like a partial paint test. Only paint the top and a light coat at the edges of the fins ... maybe top side only. Waddaya thinnk?
