Pi 1B Active Cooling case

Tue May 21, 2019 8:20 am

Hi,

Bit of advice on a case required.

I have repurposed a Pi 1B as a ADS-B receiver, the Pi is located in the apex of my garage, so I can get the aerial on the roof without a long cable run.

I’m running the Pi quite hard, with a moderate overclcock I’m getting about 50-60% constant utilization, ordinarily this would not be a problem as the 1B runs fairly cool, however up in the apex combined with a good load the old girl is getting a bit hot, I saw 75C yesterday and it’s not even very warm here yet..

Has anyone seen a case with a fan for sale or seen a good one that could be printed, I’m not expecting miracles with the cooling, after all I am going to be blowing warm air across it but I would like to try and bring the temperature down a bit.

Thanks In Advance.

Doof.

Hi,

Thought I would follow up in case anyone else had the need, I didn’t find a commercial case, however I did find this on Thingverse that I could 3D print.

I fitted the Pi with a small, sub-optimal heatsink, and a 30mm fan connected to the 5V rail.

Whilst the Pi was down I cranked up the overclock to Extreme and pushed the ARM up to 1100Mhz, from moderate, even so I saw a 15C drop in core temp.

Not had any hot weather since but I’m fairly confident that overheating is not going to be a problem…
