So pretty much everything possible to go wrong, did. First temp probe not reading, then the TEC not getting any power, then noticing block was not making contact with the CPU, and then a clamp breaking on the block hose after it was filled and running, causing me to have to run to the nearest auto parts store to replace it.
Posting from the rig now though, with all settings the same the block holds a ~8-10% lower duty cycle for the same locked temp. Mount is still poor though, at the same IHS temp the core temp is 2-3c higher...actually, its a different cold plate probe so it could just be more accurate (which makes more sense). Haven't pushed the block past 40% duty cycle yet, so no clue how the controller will hold up to its full load.
After messing with this crap for hours I'm exhausted, leaving everything in pieces and will close it up another day and get some numbers...probably Sunday.
edit: LOL after wondering why my idle temps were all over the place and my duty cycle kept going from 10% lower to the same as before, I noticed the stupid Windows Defender background process chugging away at 25-30% CPU load. Everything is fine Edited by Puck - 8/5/16 at 8:55am
