I'm still having some pretty serious issues trying to get my peltier to run properly and keep my 8320 cool.
Just a little on how it's running at the moment, she runs at sub-zero (I don't actually know how far sub because my board doesn't support sub-zero readings :lol
but only at idle. As soon as there is as much as 20% load put on the CPU the temps begin to rise above 0C but at 20% usually stop around 2-3C. I can't currently run at full load for more than about a minute as the core overheats and shuts down. I can run 50% at max before the CPU starts continually getting hotter and sits at about 30C, much more heat and the CPU just continues to heat up and then eventually overheats.
I've tried changing my thermal paste to the more commonly used in sub-zero applications to Ceramique 2 and that didn't seem to help in any way unfortunately
.
So to the real question, I know I need to get an external PSU to power the peltier for its full potential. Currently I am switching between having the peltier powered by a 12v molex and having it plugged directly up to my PSU with it using 2 live and 2 ground pins from my RM750's 8 pin power section. I'm not sure that I am powering the peltier significantly or that I just simply don't have the cooling capacity to cool a peltier and an FX8320 (only on stock) with my custom loop. In the loop I have an Alphacool 360XT (45mm), D5 Vario, Alphacool Block and 3 SP120's in push.
There is the option for more cooling if it it the case that my cooling is the bottleneck however I would be much happier if it was just the power issue. My pelt is a 400w model rated for 15 Vmax, 25 Imax and 400w Qmax with a ~65C delta temperature theoretical between the hotside and the coldside.
I have seen these on Ebay and was wondering if they would be capable of powering my pelt for above 225w.
