Haven't made it on holidays yet had to get some dental work done. So I managed to make a few mods to my configuration and I discovered some interesting things.
First I removed the Radiator and the reservoir from my loop, I kept a four way fitting in at the top of the loop so as to bleed the system of air if necessary. Also, I restored the proper direction of air flow through the FreeZone Elite.
All my testing is done at 4.2Mhz
Upon removal I did notice a fair drop in idle temps of about 4C to 5C degrees varying between cores 24C to 26C. I also tried every possible position of the variable pump speed of which there are five. The best idle setting ended up being at position 4 and what that works out to in liters per minute I am not quite sure(there are charts for that pump to indicate speeds at the various positions but felt it irrelevant because I am going to set the pump to what will give me the best results regardless of how much it is actually putting out). To my surprise however, when I stress tested the processor with Prime 95 my temps on the cores hit 75C + - 2 to 3 degrees.(I did run Intel Burn as well but Prime 95 gets things hotter and keeps all cores at 100% load) Once again I played with the pump settings and this time found temps dropped 1or 2 degrees at the 5 setting still consistently over 74C.
So back to the drawing board. Next I decide to remount the Radiator but this time at the bottom of the case with a 120cfm fan blowing cooler air from the base near the floor up through the radiator and into the case. I addition I put the Reservoir back in the loop as it did not seem to make much of a difference either way(also it was a pain in the ass trying to evacuate air through that little four way valve)
So now my idle temps are between 27C to 31C on the cores, but now my pump performs best at the 5 position, probably because the radiator is back in the loop. Next, I ran Prime 95 for a little over an hour and surprise my Temps on Real Temp max at 69C. I guess I thought I could get things a little cooler but realistically I have no intention of overclocking past 4.2Mhz and 69C with all cores maxed is certainly expectable in my opinion.
