Since we were utilizing the Intel C1E and Advanced Speed Step settings on our Kentsfield the blocks were pretty much identical under idle conditions at both default speeds and overclocked. Running at just over 1v vcore and 1600MHz doesn’t present much of a challenge for our high end setup. Let’s look at the numbers that actually mean something!
Our graphs below represent 2 tests, one at 2.66GHz and the other at 3.5GHz, 1.45v. Each chart is the max temperature each core reached during the thirty minute torture test.
We can see here that the Apogee GT leads both the Storm and TDX by a 3c-4c. Notice that two cores ran 1c cooler than the other two on the Storm block.
Our overclocked settings is where the extra cash of water cooling really pays off with more effective cooling. At a maximum of 67c all of the blocks did very well keeping the QX6700 below 70c with the Apogee GT leading the way. We do see that the Apogee had a 1c difference in temperature between the pair of cores while the Storm and TDX did not. Above 70c we have noticed that the CPU becomes unstable at the settings of our test machine so the further we can keep it below that level the better!
