    CoolerMaster 80mm LED Fan (TLF-R82)

    Colorful 120mm Fan

    Enermax WS-8SLFS

    Operating System

    Windows XP Professional w/ Service Pack 1

    Power Supply

    Allied 400W PSU w/ Bottom Intake

    • To put CPU under stress ("Load"), Prime95 was run for 1.5 hours.
    • The Heatsink Fan used to test the thermal compound was the Coolermaster Aero 7 Lite at max RPM speed (~3668RPM)
    • Heat readings was in a closed case environment (in a somewhat poorly air circulated case) and were read by Gigabyte EasyTune4 v1.0 and verified with Speedfan v4.09

    When idling, Arctic Silver 5 keeps the CPU coolest at 47oC, which is 1 degree less than the OCZ Ultra II. The AS5 cools 2oC better than the AS3, and so there was not that big a gap of performance difference.

    Under load, the Arctic Silver 5 proves that it is still superior in cooling and cools 2oC better than the Arctic Silver 3. The AS5 also cools 3oC better than that of the OCZ Ultra II compound. The Arctic Silver 3 was able to cool better than the Ultra II compound by 1oC, which isn’t really anything big.

    All in all, Arctic Silver 5 managed to cool the best during both idle and load states. The OCZ Ultra II and Arctic Silver 3 are pretty much neck to neck when cooling. This makes the Arctic Silver 5 the ideal thermal compound to use
