Thanks this is what I came here to see 😊 plus The fan one I’m about to buy at the moment is using a brushless fan so I’m sure it’s going to be the most gangster $6 of Chinisium I’ve bought
True, but with one caveat: if using the smallest nozzle, the cheap one will not have enough air flow to desolder an SMD resistor. Speaking from experience.
@@RolandV3922 That's not the case at all.. It will still have more than enough airflow to blow the whole part off of the board. I'd check that you're not blocking the air intake with your hand.
@@NicksStuff Again, there is nearly too much air speed.. The temperature is no different either. This is no different to the cheap vs expensive soldering iron thing.. they both supply heat through a tip. Just some have more features and are nicer to use. They will both do the same job.
A fan speed setting of "six, whatever that means" immediately invalidates any test if one doesn't know the L/min output at the nozzel for the setting(s). There is no way to determine how a setting of "six, whatever that means" affects the air output from different designs, so it could be your setting rather than anything related to the pump type that is causing one to take longer than the other. Example: Perhaps one needs a speed setting of 8 on the one unit to provide the same air volume output and temperature as a speed setting of 6 provides with the other unit.
I just did a quick research. On Amazon and other multiple websites, I found the same details: the Baku 858a claims a maximum 120l/min airflow with that fan. (I guess it's a standard 4020 blower fan) Instead of that, in the Baku 701b specification, they wrote "just" 0.3-24l/min. Very interesting.. I believe not just the air flow, but the pressure also matters. The huge difference is that, if anything obstructs the airflow,(you must keep close enough to the component) the fan version immediately will reduces the airflow, until the (diaphragm) pump version still will press trough the same constant amount of air just with higher pressure. (Because both knob can set from 0-8, in both case we can expect 75% airflow if both set to 6. The conclusion is, the pump version truly gives you 18l/min airflow even there is some resistance from the MB and the FET, however the 90l/min expected from the fan version is totally false in any condition.)
I purchased one with fan in the handle from Amazon. Worked it good when I first got it just practice desoldering parts, died in less than 2 weeks. Returned it, spent a little more and got one with the fan in the main unit. So much better and hasn't left me down yet. I suggest if you do buy one, work it hard the first 2 weeks to make sure it holds up and you aren't out of the return period.
@@rodiona8781 One I returned was Prostormer 120V Digital Display Heat Gun with 3 Sets Stored Temperature and Sleep Mode which was about $50. Replaced it with Aoyue 852A++ Digital SMD Hot Air Rework Station which was about $130. This was back in 2022.
Seems to be an increase in price of rework stations, well in Canadian dollars they are $130+ with a hose connection. Most that I see under $80 are ones that use a fan. What my take away from this is... if I am not going to be doing professional work for others and just need to replace an analog stick on a controller when they wear down every 3 months or so, the cheaper option for heat guns would be fine and get the job done(just not as efficiently). I can see why one would need a better equipment if they are working with fixing electronics regularly for their work or hobby. Time is their limiting factor of how much work can be done in a day. More work done = more money or more learning depending on the skill level.
When listening video it didn't sound like pump. Station what I have (Aoyue 2738) has clear pump sound that would have been on record. So I think both in this video is using normal fan. Blower fan in handle and bigger axial fan in station.
Main problem with that pump based station is weight, and fan based will become better with time because now you can buy micro trubines from vacuums and hair dryers woth ridiculous air capacity.
I own one with a fan. I think it's an issue since you going to apply heat to the component for longer time and the risk of damaging it increases. However to avoid that i would use low melt solder or cover the legs with solder
You can regulate that without a problem. More air volume carries more heat to the components. More air volume doesn't necessarily mean more air pressure (air pressure is dependent on the diameter of your nozzle - the smaller the diameter, you'll generate more pressure to push the same volume of air through it, unlike with the larger nozzle). My point was that the fan isn't pushing the same volume of air efficiently through the nozzle, like the vacuum pump would (most air pushed by the fan can "bleed" through the handle).
Honestly I find it bizarre because I have the cheaper one with a fan, and it's as fast as the faster one you have. The one I use is Yihua 959D II rework station... and I usually set the temp to 330 C and airflow about... well, I dunno the lowest setting? since I don't have that fancy percentage option. Probably the slower one you have needs a fan replacement... maybe?
It depends, over here the professional kind with the integrated pumps/large blower fans are a LOT pricier than the little fan handle ones. The fan handle ones also get a lot better than the 858a/858d clones. I just got a Yihua 959D-II after my no-name brand 858d bit the dust and i'm very pleased for the occasional use i give it. To sum it up, the fan handle kind is absolutely fine, as long as you're not doing this as a career so there's no time pressure. It just takes a bit longer.
My Sumsour hót air with dần in the handle is a beast. I plan on getting the pump version because they are usally higher quality. But my cheapo hot air that I have used for 2 years is just fine.
I have the 858 hot air. I modded it to have a higher airflow. I had just replaced the 27k resistor with 18k on the tip31 speed controller inside the control board. The standard voltage of the fan is about 5 to 6v that's to low for a better airflow. Now after modding i get around 9 to 10v and it do pretty well.
Hello. I'm hoping to make a hot air station. I want to order the 858d pcb for the station. Do you know if it's possible to hook it up with the diaphragm pump heat gun or can I only stick with the fanned heat gun? The fan heat gun comes with the 858d pcb by default on off the shelf rework stations.
Actually its not a piston inside,, its just an enclosed brushless fan, this fan handle built model had some models with brushless fan also,,, these more expensive ones have more powerful heating element in them and also their power supply play a huge part in their performance especially if they were driven by iron core transformer
I have a Yihua 952D+ with 19.5 diameter heating element, burnt out and unobtainable...anyone know where I might find one? I've checked TEMU, Allied Express, and Ebay all I can find are the 22" diameters.
I was looking for the quality one. I just want to get it for desoldering CPU socket(PC motherboard). I dont know which one to get. which one would you recommend to use for motherboard socket desoldering?
True. But sometimes using a large nozzle is not the option. You might blow away small components of the board. Throwing away kapton tape for a small solder job is not worth it in the long run. That's why volume is key in most cases.
It depends what makes airflow fro the unit. Some usrs centrifugal fan, others membrane pump. Membrane pump makes "pops" of air that makes work more difficult (it can blow out small elements).
You have to make sure the inlets for the fan never become blocked with dust. It's happened to me. The element overheats and burns through the mica insulation, then shorts on the metal shroud, so turning it on trips your circuit breaker. Fortunately mica insulation sheets are cheap as dirt, but it's still a problem you can run into. Especially at low fan speeds and if the dust is inside the fan, where you don't notice it. That's really the only reason for pistons. The fan has more air flow than you will ever need. Mine never once went above the 2 on the dial.
yes ofc you are right, the station with the air pump is superior, but I have pretty consistent results with the cheap one, I just make sure tu use a good flux and (if possible) I add a lower melt temp solder to the pad of the components I want to remove before blasting it with the hot air gun, and you're good to go...
Very helpful video, thank you. As newb to hot air stations, I would have found it very useful if you could have put the model numbers for the two stations in the description amd shown an image of the base units
The fan version is better for reballing chips with BGA balls. But it can be very useful for big boards if you have a preheater. If you have a preheater, you don't need a Air Gun with Air Pump because the main basics of working on big PCB boards is that you always have to use a preheater to preheat the full board and a minimum heat from the air gun to avoid chip destruction by heat. For the fan version of hot air guns the 8018D is pretty good because it uses a better fan and a better fan position compared to the 858D version.
few more things: as the heating element gets older it will be less efficient. the huge flow of air is useless for most if not all small components, when you need to put them back. the most important thing is the constant temperature of the airflow and the accuracy of the temperature meter. more power in WATTS = more power in removing components.
Yes. For the heating element you are completely right. Since the age of the heating elements is about the same, it makes no difference here. But, since air is the heat delivering medium, flow is really important. More air flow = more heat delivery. So it's really not meaningless. Every calibrated hot air station would be able to recover the lost heat quickly, but the point is heat delivery. If you're hinting at high air pressures being useless (you're right there), there are two great options for any beginners reading this: use a smaller nozzle and turn the airflow down a bit (smaller cross section would increase the pressure to much at the same air flow), or use the same nozzle but move the heat gun away from the board a bit.
@@WebMonster-jf6eq It was used only 6 times, before I bought the more expensive one. It looks "heavily used" because the air delivered to the heating element was never enough to cool down the nozzle and thermally balance it. Yes. I calibrated them both with a thermocouple, they both deliver a stable temperature (+-5°C). The real reason I made this video is to help everyone save time soldering and desoldering chips using hot air. If you are really so skeptical, buy both of them, calibrate them and try them for yourself. They're both only 90$ and you can always resell them if you don't like them. You'll soon realize why the most prominent repair youtube channels (Louis Rossmann, NorthridgeFix, theCod3r etc.) use 200+$ piston pump hot air stations with 1 inch thick hoses.
I'd like your opinion - which would you own if you could only use one or the other of these two hot air tools. The Quick 957dw+ or the YIHUA 959D please?
@@milanfixer Thanks. All I could afford was the Yihua . I'm hoping to use it for dc jack removal, which i will do rarely. I have a Dell Latitude AIO 5490 that has a bad dc jack that I plan to replace using the 959d. Other than that I might do a rare dc jack replacement on a laptop. Think it will do the job? Thanks!
@@noguardrails47 Oh definitely, my friend! It will do the job just fine. It will also serve you well, because you'll use it rarely. If you plan to go pro as a technician, then you should get the better kind because it'll save you a lot of time 👍 Best of luck to you with the DC jack 🍀
I bought recently a rework station which has soldering iron and hot air gun operating from a variable central unit. The reason I chose it, is the design is totally modular, either part can be switched on and off independently, has a clear and somewhat accurate gauge to indicate temp and power, the iron and gun are replaceable and the iron uses standard current tech tips so functionality all the way and repairability all the way as well. I actually now run this in a trinity with my other two irons, I have my heavy duty Lidl Parkside mains powered with a thick chisel tip, I have a variable Katsu solder station with a medium cone tip and the rework with a microfine tip plus have on the way a crows beak tip for them hard to reach places. As for the gun, yes it is the fan type but it does the job and replacement elements and fans are easily found so again the repairability, heck its cheap but does the job and I flux up on removing stuff as the flux really helps spread the heat under the area worked on :)
Helical and vertical wind pattern. Was told for large ics helical one with the fan one is better. Really popular in mobile cpu removal and reball. Vertical with the piston pump is good for small components to quickly remove small smd cap before the board heats up. Maybe their use case is important to not kill the ic due to overheating.
Não tenho certeza, mas talvez você tenha retirado o componente com mais rapidez pois já estava quente e bem ao lado do outro que você removeu anteriormente
exatamente por muito que ele tenha assoprado a pcb ja elevou muito sua temperatura espanlhando bem o calor isso é meio caminho andado para remover o outro mosfet que ele ainda por cima escolheu ser ao mesmo lado do outro se ele tentasse remover o 2 mosfet com a mesma pistola de ar que removeu o 1 seria bem mais rapido que o primeiro outro erro é não usar o fluxo pastoso que ajuda e muito a remover os componentes.
1:06 this sentence is wrong - the opposite is the case. Otherwise you are right of course. But big volume instead of big pressure is always made using a fan, not a piston. The difference clearly comes down to the totally fake "700W" that are maybe 300 at best or the low air volume due to the cone shaped air path (fan hat not enought pressure)
i just bought the 858 for 18 Dollars here in India (they are made here) , and now I am wondering my decision. shall I talk about exchange with the seller?
@@aayushsapra3982 Man, if you're a not a professional, it'll serve you very well. But if you are working on more than 10 boards a day, consider an upgrade (just to save time). Don't worry about it too much mate.
I never use my hot air station on full blast, air flow or temperature, but it all comes down to what is your usage case scenario. The air volume per time unit do not tell that much on its own, it has a lot to do with what nozzle you use too, and the pump/ventilator/fan parameters regarding pressure handling, here the piston pump shine, if you just go for high air flow then the ventilator/fans is your drug, but the two things, air speed and pressure goes together, and it all depend on a lot of variables that will differ from use case to use case.
I know what you mean. They just became unavailable all of a sudden... No idea why. In my country they are only available from local scalpers (who buy from Aliexpress and sell them for a higher price)... If you're not in a hurry, wait a little longer. Cause they'll definitely be back.
Most of the times, I keep my fan based blower at half the speed. Why do I need a piston based hi-flow air blower? I want to solder components and I am not interested in deep frying them.
Membrane pump is more stability air flow in minimum volume settings and it can be use for vacuum too. Normally if you use hot air gun solder you preheat your board and close elements near the working area
Thank you. I completely forgot to say that (I'll add that in the description). They are not. The one with the fan is 700W and the one with the piston pump is 600W. So the one that performs better is actually weaker in WATTS. Thank you for pointing that out mate 👍😊
I would gladly do that. But this particular hot air station is unavailable everywhere I looked. Just get the one with real temp control, a wide hose and you should be fine. Don't buy the ones with fans within the handle.
Sadly no. The particular one I have is not available anymore for some reason... I wasn't really recommending a specific hot air station, but more of a type of hot air stations out there. Just look at the hot air gun when browsing hot air stations and just make sure that they have a hose attached to them (that they don't have a fan inside the handle) and you'll be golden 👍
There seems to be some discrepancy between claims, this video claims the higher end Baku is piston driven, but googling and searching for corresponding products I could find the same one both piston, diaphragm, and fan powered with the fan inside the station itself.
The models with piston pumps are very noisy. I actually stumbled upon your video while looking for modding information to replace it with a blower fan. Perhaps the same for my desoldering station and its loud pump.
para principiantes y gente que recien empieza la barata es buena, de hecho con la practica sbes que tiempo o que anivel de aire usar. tienen su truco-.
About 450 degrees. Heat up the board from the pin side and when solder melts, gently pull it from the board. Use kapton tape to secure SMD components on the board and prevent them from flying off. Just be patient and don't force it. You'll be able to do it without a problem. If you have low melt solder, use it.
The funny thing is, in my country the piston pump models are actually CHEAPER (and in some cases much cheaper) than the fan based ones. It actually made me doubt my reasoning and logic as to why they selling the much better version for lesser cash.
I paid around $50 for my fan based hot air station about 1yr ago and you know what? For the little bit of soldering I do, its all I need, Its not really about the air, its more about the heat than anything, and it works fine, sure at that time the piston type was like 400% more to buy, I didn't see the need. If I was a pro or semi pro, I could see the need for it. But I'm not. :)
It could also just be that the temperature is out of calibration on the "fan" machine.. The test is pointless without proving the temperatures are the same.
He meant comparing the fan INSIDE this hot air blower specifically versus the blower piston located on the station. The hot air fan is limited to just a small size because it is located in the handle. The fan cannot compete in volume because of the inherent size limitation. No need to overexemplify his words into turbo boost or race engine which is completely different world that he is talking.
The fan version does its job very well for non-intense applications.
It remains affordable for non-professionals.
Exactly, as someone fixing their own phones and GPUs at home, it works well enough.
I'd completely agree! I've got one and it does everything I need it to do! And I've used mine in anger as well it did very well!
Thanks this is what I came here to see 😊 plus The fan one I’m about to buy at the moment is using a brushless fan so I’m sure it’s going to be the most gangster $6 of Chinisium I’ve bought
The fan type unit pushes more air than you will ever need for standard electronics work.

I have a Dell Latitude AIO 5490 that has a bad dc jack that I plan to replace using the 959d. Other than that I might do a rare dc jack replacement on a laptop. Think it will do the job? Thanks!
@@noguardrails47 Oh definitely, my friend! It will do the job just fine. It will also serve you well, because you'll use it rarely. If you plan to go pro as a technician, then you should get the better kind because it'll save you a lot of time 👍
Best of luck to you with the DC jack 🍀
@@milanfixer Thanks so much for your videos and your guidance!
I bought recently a rework station which has soldering iron and hot air gun operating from a variable central unit. The reason I chose it, is the design is totally modular, either part can be switched on and off independently, has a clear and somewhat accurate gauge to indicate temp and power, the iron and gun are replaceable and the iron uses standard current tech tips so functionality all the way and repairability all the way as well. I actually now run this in a trinity with my other two irons, I have my heavy duty Lidl Parkside mains powered with a thick chisel tip, I have a variable Katsu solder station with a medium cone tip and the rework with a microfine tip plus have on the way a crows beak tip for them hard to reach places. As for the gun, yes it is the fan type but it does the job and replacement elements and fans are easily found so again the repairability, heck its cheap but does the job and I flux up on removing stuff as the flux really helps spread the heat under the area worked on :)
whats the actual model number of the piston pump one
Helical and vertical wind pattern. Was told for large ics helical one with the fan one is better. Really popular in mobile cpu removal and reball.
Vertical with the piston pump is good for small components to quickly remove small smd cap before the board heats up.
Maybe their use case is important to not kill the ic due to overheating.
Model numbers & cost? 🤔
Hey Buddy wich model is the best one ?
Thanks
So where does one get a "good" pump one?
Não tenho certeza, mas talvez você tenha retirado o componente com mais rapidez pois já estava quente e bem ao lado do outro que você removeu anteriormente
exatamente por muito que ele tenha assoprado a pcb ja elevou muito sua temperatura espanlhando bem o calor isso é meio caminho andado para remover o outro mosfet que ele ainda por cima escolheu ser ao mesmo lado do outro se ele tentasse remover o 2 mosfet com a mesma pistola de ar que removeu o 1 seria bem mais rapido que o primeiro outro erro é não usar o fluxo pastoso que ajuda e muito a remover os componentes.
Ele diz no começo que ele iria deixar esfriar para tentar novamente com a outra pistola
1:06 this sentence is wrong - the opposite is the case. Otherwise you are right of course. But big volume instead of big pressure is always made using a fan, not a piston. The difference clearly comes down to the totally fake "700W" that are maybe 300 at best or the low air volume due to the cone shaped air path (fan hat not enought pressure)
The longer the heat the longer it will stress the SMD component you are trying to desolder and resolder, that is the issue on the fan type
Thank you for the watts information in the description. Perfect description
i just bought the 858 for 18 Dollars here in India (they are made here) , and now I am wondering my decision. shall I talk about exchange with the seller?
@@aayushsapra3982 Man, if you're a not a professional, it'll serve you very well. But if you are working on more than 10 boards a day, consider an upgrade (just to save time). Don't worry about it too much mate.
@@milanfixer ill mostly use it for heat shrink tube and removing/ replacing components once a month maybe.
@@aayushsapra3982 in that case it'll be perfect for you. May you use it in good health 😁
Which make model you purchased?
Is 24l/min air flow enough in most cases, or should I go for the QUICK 857DW+ with 100l/min?
I would also be interested in this question. Can anyone answer it?
I never use my hot air station on full blast, air flow or temperature, but it all comes down to what is your usage case scenario. The air volume per time unit do not tell that much on its own, it has a lot to do with what nozzle you use too, and the pump/ventilator/fan parameters regarding pressure handling, here the piston pump shine, if you just go for high air flow then the ventilator/fans is your drug, but the two things, air speed and pressure goes together, and it all depend on a lot of variables that will differ from use case to use case.
Which soldering station is best for pro or bussiness purpose like fast and durable
ok but this with pump have smaller length ... and its more complex to got it to work while your have lot of equip around.
That $55 station seems to be $200 now...
I cannot find a cheap (like $50-70) station with the fan or pump in the base :-(
I know what you mean. They just became unavailable all of a sudden... No idea why. In my country they are only available from local scalpers (who buy from Aliexpress and sell them for a higher price)...
If you're not in a hurry, wait a little longer. Cause they'll definitely be back.
Where are you buying these stations at the prices you quoted?
Nice video!
Question,
whats the model for the Baku piston pump version? I might look in to it.
BAKU Model: ba-942E
Use the old one to make a bottom side heater with an angle 90 metal corner
Most of the times, I keep my fan based blower at half the speed. Why do I need a piston based hi-flow air blower? I want to solder components and I am not interested in deep frying them.
Membrane pump is more stability air flow in minimum volume settings
and it can be use for vacuum too. Normally if you use hot air gun solder you preheat your board and close elements near the working area
A single "Nope" Would be enough for this vid.
True! 😂😂😂
May i know which model for the new station ? I also looking for new hot station
Quick 957dw
Did you calibrate the temperatures?
are the stations same power in WATTS? if not, the comparison is not so meaningful
Thank you. I completely forgot to say that (I'll add that in the description). They are not. The one with the fan is 700W and the one with the piston pump is 600W. So the one that performs better is actually weaker in WATTS.
Thank you for pointing that out mate 👍😊
What about replace tips for the soldering Iron this is a major selling point if there are any replacements
Thanks for the info. Very helpful. 🙏
Greate for content. Thank you.
Would be great if you could share a link to where this could be purchased.
I would gladly do that. But this particular hot air station is unavailable everywhere I looked. Just get the one with real temp control, a wide hose and you should be fine. Don't buy the ones with fans within the handle.
@@milanfixer that's the one I wss referring to, the one with the hose. I already have one with the fan (898D)
Any chance you can put up a link where to obtain the piston one
so could we all have a model number or link to the "good" one please?
Sadly no. The particular one I have is not available anymore for some reason... I wasn't really recommending a specific hot air station, but more of a type of hot air stations out there.
Just look at the hot air gun when browsing hot air stations and just make sure that they have a hose attached to them (that they don't have a fan inside the handle) and you'll be golden 👍
@@milanfixer Thank you kindly for letting me know, best of luck with everything.
There seems to be some discrepancy between claims, this video claims the higher end Baku is piston driven, but googling and searching for corresponding products I could find the same one both piston, diaphragm, and fan powered with the fan inside the station itself.
How about cutting more air slots on the handle?
That could work, I guess 🤔. I just didn't want to bother with that.
@Discord-Serwis_Elektroniki_PL Thank you for sharing mate. That could definitely work 👍
The models with piston pumps are very noisy. I actually stumbled upon your video while looking for modding information to replace it with a blower fan. Perhaps the same for my desoldering station and its loud pump.
para principiantes y gente que recien empieza la barata es buena, de hecho con la practica sbes que tiempo o que anivel de aire usar. tienen su truco-.
The fan version arent good to work with video card.. but its nice to work with cell smartpho e
What temp should I use to remove analog sticks from Xbox circuit board?
About 450 degrees. Heat up the board from the pin side and when solder melts, gently pull it from the board. Use kapton tape to secure SMD components on the board and prevent them from flying off.
Just be patient and don't force it. You'll be able to do it without a problem. If you have low melt solder, use it.
Appreciate it!
The funny thing is, in my country the piston pump models are actually CHEAPER (and in some cases much cheaper) than the fan based ones. It actually made me doubt my reasoning and logic as to why they selling the much better version for lesser cash.

Thanks for pointing out that difference about the fan vs the piston pump
this true I just replaced my old one and my new one works so much better.
I paid around $50 for my fan based hot air station about 1yr ago and you know what? For the little bit of soldering I do, its all I need, Its not really about the air, its more about the heat than anything, and it works fine, sure at that time the piston type was like 400% more to buy, I didn't see the need. If I was a pro or semi pro, I could see the need for it. But I'm not. :)
Makes no sense. The one with the hose will break faster, wont it? And if you wont do the actual tests how can you claim one is better?
Cant find anything but the fan in handle ones unless i spend $120+ USD
Liked and subscribed to your channel keep it up bro great work.
What's that model bro?
Thank you very much mate! It's a Baku 852 (but I recommend getting a Baku 702, if you're looking for cheap and decent 👍).
great explanation for a newbie like me, thanks!
so turn the first one up to 9 then
You do not want to be pushing to much air so it can blow all the little components as well you want as little air as possible that will do the job.
Excellent explanation
What is the cost difference for a hobbyist. If the nice one is 4x the price then that's where it matters too
It could also just be that the temperature is out of calibration on the "fan" machine.. The test is pointless without proving the temperatures are the same.
what the difference?? the price
oh man, I had that exact board! eons ago
after watching this video i bought piston pump for 34.09 USD im learning how to use it
This comparaison is not revelant. You start with the RSpro and for the second the ground plane is still hot.
Thanks for the info it helped a lot.
The baku piston will not last longer, I have experience using both for decades and often changing the baku piston head nose
Turn power up on cheap one
If its make the work this mean its good
Search for vertical wind vs spiral wind smd.
Piston does more volume than fan? Tell that to race engine manufactures that use turbo boost or superchargers.
He meant comparing the fan INSIDE this hot air blower specifically versus the blower piston located on the station. The hot air fan is limited to just a small size because it is located in the handle. The fan cannot compete in volume because of the inherent size limitation. No need to overexemplify his words into turbo boost or race engine which is completely different world that he is talking.
Thank you.
If u want fast desolder than use vertical nozzle.
The pump is very nice I'll say that ..!!!
Me personally don’t like a lot of air cuz it pushes smds off
My soldering station goes to 11, so it's almost twice as good as your "expensive" model which only goes to 6.
You're absolutely correct. Can't argue with that 👍😁
Mosfet is getting suffocated.
Try this with a xfx rx 580 bro... there is a lot of copper there..
thx very informed video
I don't agree with you. like mine with fan 700w can remove bigger components like 20 second
Temperatura mais alta fez com que o componente se soltasse mais rápido
