I recently built an core i5 based system. It's not overclocked, running Win 7 and has been puttering along stably for about a week now. To see if cooling (using a ZALMAN CNPS7000C-ALCU cooler).
Here is my question: Using the little Utility 'Core Temp', it appears that core 0 through core 2 are generally at about 22-23C at idle temp. Yet, core 3 has an idle temp of 30-31C. The lowest temp for core 0-2 is 22C while the lowest temp on core 3 is 28C.
So far, I have not tested under continuous load, but at around 10% load all cores are in the low 40% with core 3 always running slightly hotter.
Is this something I should be worried about. I know the temperatures are so far extremely low, but I am simply wondering if this might mean that the cooler is not seated properly or that I put the paste unevenly onto the CPU. Any thoughts?
Finished running OCCT o/n. Temps and core voltage remained stable throughout the test. Max temp was at 67C for one core and the temps hovered mainly around 62-64C.
I would like to run the other tests OCCT is capable of running, but it seems that two GPU tests and the PSU tests are grayed out and not accessible. Does anybody know the reason for that? And is there another program that I can use to test the system on '100%GPU+100%CPU' at the same time? I have a passively cooled Radeon HD5750, so I would like to know how it affects the temperature of the whole system.
