Re: Klondike - 16 chip ASIC Open Source Board - Preliminary
That temp reading is right but it's not close to the ASIC mounted. On next board revision I'm going to place the thermistor in the center of a quad of 4 ASICs so it should get a closer approximation, and of course once I do some testing I'll add an offset adjustment. Yes, it's actually 34C at my work bench
If you put a thermistor per 4 asics then wired them series parallel you could get an average for entire board. How well does the heat conduct to the top layer? I wonder if adding some thermal vias to the thermistor would get it close to actual temp.
