I think this is a slightly different question related to hardware temperatures. I am curious about the drop in temperature after adding a fan and the impact of temperature on processor efficiency.
I am in the process of building a Raspberry Pi 3 cluster. Only 3 nodes so far, but I hope to use it to learn and crunch numbers for SETI@Home.
With all three boards running the BOINC client at maximum capacity, here are the temps I'm seeing with vcgencmd measure_temp:
Rasp1 = 82.2 C
Rasp2 = 73.6 C
Rasp3 = 70.9 C
As a test, I took a regular house fan and ran it on the cluster on high for 15 minutes. I checked temps again:
Rasp1 = 47.2
Rasp2 = 43.5
Rasp3 = 42.9
Here's my question, will the cooler cluster run more efficiently and perhaps process at a faster rate?
I may invest in a smaller fan designed for the job to keep these boards as cool as possible.
Appreciate any thoughts or feedback!
