I see you have the rpi B model with a case, I have the B+ no case, my temps were always around 84.00F max usually always around 80.00F, last night I logged into the pi and overclocked the pi's frequency to 450mhz without upping the voltage, just to see if anything changed with the hash rates or to see if the BET0 or the new BET1 errors I was getting on reboot/restart would go away. Since I overclocked it the only thing ive noticed is the slight temp increase to 88.00F and a slight, probably just by chance, lower rejection rate, not enough lower rejection rate to say it solved anything. But I have never seen my pi B+ get anywhere close to some of those temps you had. Do you think with the case on it maybe trapping some heat inside it? In two of your pictures I noticed one said 102.00F and the other said 104.00F. Was that before the fans? I have my pi sitting next to one prisma, right below them on the next shelf down is a window box fan blowing air up to keep the bottom of the prismas cool. Also two fans per prisma, push/pull, and one fan between the prismas blowing air down the middle of them. So I guess I was getting lucky with the placement of the pi as its getting cool from the box fan below it. I just wish we had a way to get the true temps of these prismas while running. I have a laser thermal gun, but the temps are sporadic depending where I point it at. The exhaust fans are around 120F on both units consistently. I am running them right now with no overclock as im worried because of the pictures posted. Better safe than sorry. Does anyone know if there is a way to find the true temps these prismas are running at? Are they even capable of giving us that information?
