Hi, im currently water cooling an i7 3820 which is under a EK Supremacy nickel plexi with some AS MX-4 in between, its fed by a D5 with new EK top (3/8 tubing). At stock the idle temps are a bit higher than I was expecting coming from a Xeon 1245V2 (an i7 3770 for heat purposes), I was expecting higher temps as SB-E runs hotter than IB but im getting around over 10c higher at idle.
Anyway under Prime at stock clocks I can hit nearly 70c which is basically where my 3.8ghz i3 540 system with a Corsair H50 sits in the same test. A full blown water cooling system should be giving better results on a stock 3820 no? As to the temp behavior when a stress test starts the temps will spike up then drop slightly and rise stable until they reach their staying point, when the test ends they drop off nearly 30c instantly then slowly go back to idle.
While the test is taking place heat output isn't anything massive, the tubes are not hot to the touch and neither are all the rads. I was hoping to OC this system but if it can hit nearly 70c in Prime's highest stress test at 3.7ghz (turbo) im worried what it would do at say 4.5ghz.
*EDIT*
It just seems when the stressing kicks off that the temp rises much faster than it used too on my IB, that spiked slightly and gradually raised the temp until it leveled off but the SB-E is raising it much faster and higher, like the heat is coming out faster than can be taken away, but as it drops off straight away when the test ends that can't be right.

this is basically the same setup I had with the IB CPU all ive done is change to a Corsair 500R case, added a XSPC EX240 in the top and swapped the Z68/IB for a SB-E 3820 and an EVGA X79. I was expecting the addition of the EX240 to counter the IB to SB-E heat increase as the CPU's have basically the same stock clocks/turbos.
