- In this video, I test out a Thermoelectric cooler on the Raspberry pi 4 and it worked out really well even when the Raspberry pi is overclocked, it's actually the best cooler I’ve tested on the I so far.
This Cooler uses the Peltier effect and is actually classified as a solid-state active heat pump, It transfers heat from one side of the device to the other using electricity.
Basically when you apply power to the heatsink one side gets really hot and one side gets really cold.
The thermoelectric device I use in the video is a low power version but the cold side can still get down to 8 degrees celsius.

The cooler used in their video was designed to be attached to the back of a cell phone it has a rubber coating on the cold side and in my testing I haven’t had any condensation issues, I believe it has to do with the low power consumption “ when compared to other thermoelectric coolers” and the rubber coating that used on the cold side.
Is custom SBC possible if pls make vedio on that
Yeah , condensation can be a problem, but i like your idea of attaching it to the flirc case. Would love a video testing it!
Amazing idea i really love it. Thanks for showing
If you want to cool it a bit better you could remove the CPU IHS and cool direct on the die, would need a layer of paste.
Could this cause condensation on the cpu? or corrosion?
Wow! An American using Celsius 👍 I'm impressed 😋
What’s that supposed to mean, where I’m from they teach us it plus Celsius is better
@@TheKingDrew they use other measurments types
I could imagine BMW using these in cup holders to keep your drinks cold, but charging 100 time's thier cost and claiming it's cutting edge tech. 🤫😂
Sub-ambient cooling is not really recommended, even on desktop PCs. Condensation can collect and that can be seriously damaging. Go cold enough and that condensation can become ice. You'd have to keep a high level of load on CPU in order to keep it from forming condensation!
Yup... entirely impractical.
could combine it with an system submerged in a nooconnective fluid.
Or if you really wanna shoot high a vacum chamber.
@@danis8455 If the system is in a fluid, why do you need the cooler to begin with? The natural convection and heat sinking properties of the fluid itself would be more the sufficient in keeping the Pi cool under even strenuous loads. Plus, the added surface area would work wonders to let it bleed off any heat delta higher than ambient.
Also, vacuums would make the cooling of the peltier given the current setup, impractical. It works off using air to cool the hot side, which isn't possible in a vacuum. Only radiation is possible, which would require an entirely cooling setup. What you could do is try and run it in a dry-air environment, which would make the possibility of condensation impossible.. except now you're introducing the increased risk of arcing and static electrical discharges.
A better solution would be to coat the at-risk areas in silicon conformal coating. This would prevent the build up water directly on the components and reduce the risk of water-damage or shorting. Or.. set up the cooler to be regulated by the Pi itself. This would make the cooler more power efficient (it wouldn't need to be at max cooling except as temperatures rose, thus making it draw less power overall) and coupled with temperature monitoring would prevent it reaching sub-ambient temperatures. This however, is still very inefficient compared to a bog-standard heat-sink and fan combo except in limited application systems, where heat sensitivity is a limit compared to power draw.
Interesting experiment. Keep sharing your different cooling approaches for SBC cooling solutions. Thanks and as always, stay well!
Great video!! Loved the visuals for the temperature cooling
Try with a copper shim vs aluminum. Thanks for sharing. Always enjoy your videos. My younger me applud you.
That is the coolest looking cooler I've seen so far.
this is a really great vid, i'd love to see more cool, weird stuff like this :D
ETA Prime ... i really enjoy these video's specially cooling ones.
I tested a lot of coolers in my days when I build pc's.. water cooling.. gigantic passive cooler...or men I love myself some cooling methodes.
Specially to see the better results, like this video it gets me all excited again for doing stuff like this myself. 😅
Love crazy content like this hell yeah
just use the ice tower, 5 degress warmer but way less power usage and it looks cool
Much, much less noise, because this fan has to work like crazy, to draw all the heat away from the peltier element
TECs are nice but really inefficient
Looks cool as foook
Nice review, thanks. I was familiar with them, on overclocking for pc tower in the past nities. Then it was important to be aware about humidity level on the room, for a long lapse of use. Because is easy that appears condensation on the cold side and affect to cpu or motherboard
Little remark 'bout measuring with An IR thermometer: the metal heat spreader on the SoC van reflect ambient IR, for reflective metals it's better to measure the surface while it's covered with a non reflective material in IR, eg Paper masking tape.
Hey this looks mighty promising for my abnormally hot and damaged Pi 3b! Cheers for this!
You can use dielectric grease to seal off areas susceptible to moisture.
Emuelec v4.0 beta 64 is amazing! Never thought PSP games would run on my gt king pro at 1080p! Looking forward to your future videos and possibly talking about if the company will include GameCube and PS2 in the future!
TEC coolers! Ahh, fond memories of overclocking Celerons with these back in 98. Still got a bunch in a box, just the TECs without fans or heat sinks.
and thats why I subbed.... always good....stuff...
Great video , you should try the test with Thermal Paste, I bet it would lower the temps further !
Peltier coolers respond really well to water cooling. Just run it with an adjustable bench power supply so you can optimize the efficiency (efficiency decreases sharply with higher voltage).
What is incredibly practical is to use this with the HQ Pi camera. One of the primary sources of noise in low light cameras is thermal noise. Most high level astrophotography cameras use Peltier coolers. Some astrophotographers mod DSLRs with Peltier cold fingers. The HQ camera, while not in the same league, has shown promise for astrophotography and other low light work. A cheap Peltier cooler like this cooling the $50 HQ camera with a Pi 0W could make a phenomenal sub $100 astrophotography rig. And yes, I know, the pixel size, exposure time and readout mechanics of the HQ limits use in long exposure use. But for the price this would be great for stacking exposures.
🤘😁🤘
Another great video!
I like it. What's about the condensation from the temperature differential? Also, if we're using something of this size, why not just utilize a larger passive heatsink with no moving parts? Anyway, always intrigued to find TH-cam recommending your videos to me. Great job and see you on the next one.
Thermal paste says hi.
I don’t think thermal paste is going to help much given that there’s rubber padding on the bottom of the cooler.
@@AWriterWandering It would still help, even if only a bit. Paste fills the tiny crevaces on the two surfaces and transfers heat faster. In theory it should work on any type of surface.
@@nicklong27 How about thermal pad?
@@R0b3rt2Yonas I've never used them but my understanding of pads is that you need a lot of pressure to make them work, more so than normal paste. Cable ties won't be sufficient for that so stick with paste. Or just go bare back like Mr Prime here.
@@nicklong27 oh yeah, those cable ties make me cringe a little bit.
I played a lot with peltiers and thermoelectric coolers, but with the objective of make a portable air cooler. The key is that the more cooler you put the hot side, more cool can put out on cool side (and lower temperature). For me, it was a pain, trying to isolate both side so doesnt interact across the sorrounding, and get the best perfomance out of the peltier. As a computer cooler... it is risky, but as more success this could have, more investigation will get this kind of tech.
Amazing bro
The best use for these modules is utilizing the Seebeck Effect.
The Mars Rover has a Plutonium core surrounded with these thermoelectric modules. These modules supply power to onboard systems including mobility.
No unreliable solar panels needed.
Its blackshark funcooler white. I use it as my raspi 4 server cooler and run it 24/7. You have to watch the condensation though since its lower than room temp. My approach is by using passive cooling case and strap the cooler on top of it, then clear the condensed water once a week.
@ammonitida maybe. Do you have other approach?
@ammonitida already bought pi 4. Use pi 400 means another investment, and it still hard to find in my country, especially for decent price.
Great experiment. If able to control and ensure no condensation gets on the board, it would be awesome. A good example of a neat chip cooling method, but practically not viable. (I know you already knew all of this and was just experimenting, the comment is not meant to be derogatory, just commentary)
I’d suggest the low power state, but also a sustained heat applied to the cold side from the hot chip (non humid environment helps too) helps to keep condensation at bay.
Thanks for this video 👍🏻👌🏻✌🏻
5W with 5Volts means you need additional 1A of current on your power supply and you have to send it directly to a cooler (USB often sends only 0,5A) but it can work
Wow... That's Cool.
Cool, very!
Practical, not in the least bit!
this is awesome
Looks like a dang LCAC !! (Landing Craft Air Cushion).
I would love to see this channel ported to Rumble!
great idea to make water on your rasp!
Cool!!! A shout out to the Drone Bot Workshop. That guy does incredibly informative material!
This technology has a lot of potential...It can produce condensation but that's about the only major issue. Great Job!
You left out power consumption
@@Bob_Smith19
And that...yes
A nice use for a sterling engine.
Cool video. :-)
U hard to work broo thanks
I remember people having condensation issues with those things on the pc some years ago
I would like to see a more serious version of this to test overclocking. How much does keeping the temperature close to room temp help? You could use the Pi to PWM the peltier with a simple mosfet circuit and a Python script. For the heatsink go big with a Coolermaster Hyper 212 Evo or something. I know it's impractical. But it's fun! 🤪
Liked for using Celsius
I have tried peltier cooling my rpi4 for fun , it created lots of condensation even if I used a 172Qwat 24.6volt peltier at only 5volts.
What if you use dielectric grease to seal the board so it doesn't get condensation?
For the next test you should use a 50 watt peltier cooler and then a 100 watt version.
Might as well go all the way!
dude that's so cool , if you put thermal paste in there , i think it's gonna be much cooler
Cool! 🤩
This is cool
The cooler looks like the shroud on my old lawnmower. :)
A video on that slim rpi4 would be nice. But I will settle with an explanation.
Using a peltier cell that's not a good idea, because this device creates a lot of condensation
mmmmmm moist.
As long as it's above ambient temperature, there will be no condensation.
@@achannelhasnoname5182 Depends on how humid it is.
@@PSNGormond facts
@@achannelhasnoname5182 peltier cells usually generate temperatures below ambient / indoors ones.
Then there is the humidity rate to consider, as he already wrote @Gormond
I Def want to see how affective this would Be if you mounted it to that raspberry pi passive cooling cases.
I use a 5V 40x20 Noctua fan on the IceTower, a small copper plate on the CPU between good thermal paste dabs. The 64b Ubuntu server never goes over 23C on my pi 4 4gb (not overclocked). It is close to being cheap but highly reliable even if the fan fails.
You should buy a can of conformal coating. Mask off the components you want to cool, coat the board on both sides + edges of the board, unmask/mount the Peltier, and let it rip full blast just to see if condensation matters on a fully coated board.
Suggestion, put the cooler on the Flirc case to make the flirc case more cooler and it look nice instead straight on the chip. Maybe you can show it on the next video.
If you are game. I would try slapping that on top on your FLIRC case. Might be too much metal to cool. But it may work!
you can get tec's of ebay and amazon really cheap. we have been using stuff like this for 20 years on computers. you need thermal paste, and copper nut aluminum for that heatsink. also you need something to protect the board from moisture. once you start cooling below dewpoint you gonna condensate. superlube makes a great gel that has ptfe in it and works great.
I know this "isn't practical" but it might be perfect for in-vehicle Pi projects.
It'd be interesting to wire up a standard heatsink and fan and maybe mount a peltier cooler to the opposite side of the board that only kick on just before thermothrottling kicks in...
I put a massive old heat sink from a Dell workstation on top of an Argon One case, and it makes my overclocked Pi significantly cooler than the case alone. There should be no reason that the TEC on a FLIRC should not work better.
The reality is that you have thermal resistance between the actual IC Silicon Die and the outside case. You quickly get to a point of diminishing returns when cooling a chip. You could freeze the metal case with liquid nitrogen but the silicon will still get hot.
Argon or someone should make a case that uses this, with a little mcu/script that keeps the Pi at Ambient + 1 degree F minimum to avoid condensation. Maybe even use 12V for faster response time.
Edit: Looking forward to the Flirc test.
its like your piilow at night 1 side hotter, the other side cooler. :)
Have never heard of one of these. Found it interesting.
Lol, made a pie tec cooler about a year ago, custom heatsink made from a 1u server heatsink. Did it to push the gpu to the absolute limit.
I have played around with them in the past and there's a way around the condensation effect, but it completely negates using the peltier cooler in the first place.
Does dielectric grease work and let the Peltier effect work too?
Adding some thermal paste between the pads can increase the thermal conductibility and decrease the temperatures.
I'd love to see this with the rock pi 5b
These were really popular in the 1990s with slot pcs like the athlon and pentium 2/3
I was wondering about setting this up under control. Something similar to what some of the fans do. Set it for say 35C to kick on and off at say 30C. That should minimize the condensation issue. Please do the Flirc version of the test. I have some spacers between the board and the bottom cover on mine(enough that SD card fits between the case and the bottom) . If you set it on it's side it keeps it 3-5C cooler.
Maybe someone will get fancy and add a hygrometer, external thermometer and dew point table and a control it with a pi pico?!
Hoping you read this.....
I watch all your videos you have helped me so many times....
Hi, recently bought pi400 got it to boot to a 1TB SSD card and upon updating the image I have I accidentally typed in “0” instead of a capital “O” and now my system won’t even come on? Anyway to fix this?
You think a thermo cooler would be more effective then a sff cooler and fan? For very thin desktops like the deskmini series. Could also just sandwich one inbetween the CPU cooler and the CPU and use longer screws to accommodate the extra space but would that in a slighter larger cooler then you tested here be more effective then without the thermo cooler?
How about making a custom watercooling block the size of the PI on your slimmed down PI. and see how cold it would get then
Just watching it on Rasperry Pi 4 4GB 2,147gHz OC cooled with a solid aluminium case with 2x30mm fans. IMO my setting is enough for cooling Pi down, for usual stuff never goes over 47C, usually sits around 42C, when its working on usual stuff like YT, Slack etc.
Hope the fan can keep up with the heat that it is creating, if not the peltier cooler wil act as tiny insulation layer. I recall Linus Techtips doing this on an intel system, per saldo it only made it worse. Specially when it can't disapate the extra added heat.
Put the whole RPI in a non-conductive liquid. Super cool the whole thing with a peltier cooler.
thats the cutest peltier ever!
I remember that you used to be able to get Peltier effect coolers for PC CPUs, in like the Pentium III days I'd say? But they stopped being a thing. I don't understand the jargon but apparently they're just not effective enough, and they create condensation which is a no-no inside a computer.
Yeah, a big problem was not having a PWM controller back then, and relying on switching which wasn't very stable. The new special coolers commissioned by Intel are...well, existing if not common examples of the technology reimagined.
Could we maybe get an emulation test on an original google pixel. I have one lying around that I may try to replace the battery and see about messing with.
You are going to need a special paint to protect the electronics from condensation but drag the heat out of the CPU, What about going with the ASETEK Vapochill Lightspeed XE-II
You can but a 5V 1A Peltier cooler for a couple of dollars. Just put a heatsink and fan on top.
Great Video! Ok, I have a situation, with multiple units in an industrial setting that experiences high temps during the hottest days of the year (no a/c). The cases of the units don’t lend themselves to water cooling adapted however I believe this might do the trick.... Why is water cooling still popular with this method working so efficiently? And, has anyone produced different form factors / models of these types of units for pc/server cooling? Thanks for the content! Apologies after re-reading, the units in question aren’t Pi’s they are HP servers.
Might wanna check cooler master ml360 sub-zero
Robert Yonas THANKS! One other q, per Ciro below, how is condensation dealt with? GREAT VID GREAT TOPIC!
@@TheJacklwilliams it has built in sensor that will watch your condensation level. You can set it to ignore the sensor via software.
You can try to remove metal cover from SOC with scalpel. And in my case whole temp goes down another 10 degrees c
How did you mount a heat sink to it? Thermo cement, pad...?
@@tombyrer1808 with rubber band :)
@@xlazom00 I've done that before! Needs to be replaced yearly though ;/
You should make a video about how to receive an SMS when you press a button (using a raspberry Pi)
peltier coolers arnt very efficient, using convection is more efficient pi does not need to be as cool as possible just cool enough to keep resistance lower. just for curiousity how much power was it using ? also you might have better luck banging it on and off to maintain 70 deg with a mosfet or relay
I'd like to see if this works when applied to the top of an argon 1 case. they seems to get very hot over time
Id get this for other projects also. Wonder if i can get it in the n64 somehow.
did u use any thermal paste? what about a test with a desktop CPU?
You can stack the chips to increase performance.
Is slimming down the usb ports as simple as desoldering the double stack and soldering in a slimmer version? What do i need to know to do this besides becare with the removal??
Chilling the Nand flash might have negative impact on its performance.
Isnt the high watted version gonna mess up the raspberry pi because of the ice melting on the bord probably.
This sounds like it'd work with the Argon 40 case externally.
I would warn you about dew point and condensation, but I'm sure you already know.
sadly peltier's condensation kinda scary for hours usage, and if it fail those heat will go direcly to cold side
Interesting and cool but if it doesn't expand the overclocking it brings a power penalty with no value.
Please do XiaoMi Mi 10T unboxing and reviewing games and emulations
Interesting 🤔 🥶🥶🥶
