Pi dual fans


#1

Hello all. I was wondering if anyone ever used fans or dual fans to keep the raspberry-pi cool? I found this. Any thoughts?

We’ve never needed to here, it never gets hot enough :(

They should do a reasonable job of cooling, though, since the Pi doesn’t need that much airflow.

Would be interesting to see test results with and without the fans.

Well since you mentioned that someone ran a good test. Seems to work very well. Not sure If I will get it for my Picade but maybe for my Retroflag Nespi case.

I have been using a single fan case and it makes a heck of a difference temperature wise. Might be overkill but the overclocking settings I use make quite a difference on the more depending emulators.

My pi3 is around 30 degrees under load overclocked to 1400 ghz. Cant remember the rest of settings but have overclocked ram and gpu as well.

I actually tried it with the fan off last night and it gets quite toasty.

This is the case I use https://www.amazon.co.uk/TRIXES-Clear-Acrylic-Cooling-Raspberry/dp/B01BKIQJD2/ref=sr_1_6?ie=UTF8&qid=1507649857&sr=8-6&keywords=pi+case+fan

I also use the gorilla heatsinks.

I know toasty is not very scientific so I will try to get some numbers.

Did a little test running the 64 emulator.

First just after boot with fan plugged in

With fan unplugged

With fan plugged in again

So the fan makes about 20 degrees difference. Without a fan its temp is in the sixties and with it plugged in its around the mid forties.

Thank you for this! I’m not surprised there’s a difference, but 20deg is quite significant! I guess this is basically comparing some cooling with no cooling at all though, so perhaps that makes sense.
