Cooling the pi with chinese/xiaomi usb stick fans

Tue Sep 04, 2018 9:08 pm

Is cooling with such a fan will have any effect? I am going to overclock my pi for heavy emulation and desktop usage, will such a fan help? I am also having ceramic or Silicon carbide heat sinks as well.

Oh... that one, I have the same one.... with the clock function.

Yes it will work in conjunction with the silicon carbide heatsink, though it may look a cumbersome. It will cool the RPi.

and where will this fan of yours be plugged? RPi's USB port or other USB port? Better not RPi's USB port.

I imagine (head still hurts) that the RPi will not be in any protective case as well, is this correct?

the fan i am thinking to use is this:
https://i01.appmifile.com/v1/MI_18455B3 ... height=420
I have not purchased any of the items yet.
I will be using this on a simple RPi red or black official case or some other case or might simply use a DIY cardboard case.
I will remove all that blue rubber insulation so that the cord becomes more flexible and easy to fit inside a case.
I've seen that the fan uses around 170mA and the max output from Pi's USB is around 140 mA, So I am going to use a separate usb phone charger to power the fan.
How do you cool down your Pi? how's your fan powered? Can this mi fan be used with GPIO?

Why not save yourself the trouble and just get a purpose built Raspberry Pi case with fan set. and usually those come with heatsinks. There are a lot in ebay, amazon, or from any of your favorite online shopping sites.

Ok here are something similar to that I have used.

https://www.amazon.com/iUniker-Raspberr ... ry+pi+case

if you dont want a fan then this one will do perfectly.

Actually a mini cpu fan is a lot expensive because of extreme shipping charges(more than the fan itself) in my country. A chinese usb fan is easily availabe in any nearby shop then the cpu fan your recomending, same is with the case as well. That is why I am thinking of trying this fan.

Anything that will move air over the heatsink will work.
even this:

That looks like a nice fan. Where is the USB plug or does it connect through GPIO?

I used an elephant fan to cool my Pi 3B when running benchmarks. This worked well in conjunction with a small heatsink. For similar benchmark runs with the Pi 3B+ I used a hairdryer set to cool mode (sorry no picture this time).

I've used something like that myself.

ARCTIC Breeze Mini USB Fan with Flexible Neck

It would work best if the Pi was not in a case, but the setup above did run cooler with the fan than without. That fan in my picture actually moved a surprising amount of air, and made less noise than many small case fans. The fan you posted looks wimpier and may not provide much cooling.

I never liked the noise associated with fans (even quiet ones), and they eventually end up filling your system with dust. So I now use the Flirc Gen2 aluminum alloy heatsink case for my Pi 3B and 3B+ computers. It not only looks cool, it keeps my Pi running cool!

If you're going to have very heavy usage, then this kind of fan will certainly help. I have a case with one of those tiny GPIO-powered fans on mine, and while it helps tremendously, it can't run at full load forever. USB fans like these are a lot more powerful though. I recommend pairing them with an adhesive heatsink, where you (carefully) remove the adhesive and use thermal paste instead. The paste made a big difference on mine.

Its manual controlled. :D
