Cooling at Stock Speed

Some users will never overclock their CPU, but they still want to run the coolest CPU temperatures possible to enhance stability and extend CPU life. The Thermalright Ultra 120 Extreme, as in the recent Ultra 120 review, was tested using a 120mm Scythe S-Flex SFF21F fan.

X6800 Stock (2933MHz) IDLE Temperature

The Thermalright Ultra 120 was outstanding in our stock cooling tests; the Ultra 120 Extreme is even better. Where the very good Intel stock cooler keeps the X6800 at 41C at idle, the Ultra 120 manages 27C, which matched the Tuniq Tower 120 as best we have ever measured in testing at stock speeds. The Ultra 120 Extreme sets a new record at 26C, which is the best performance we have ever measured at stock idle.

The stress test simulates running a demanding contemporary game. The Far Cry River demo is looped for 30 minutes and the CPU temperature is captured at 4 second intervals with the NVIDIA monitor "logging" option. The highest temperature during the load test is then reported. Momentary spikes are ignored, as we report a sustained high-level temp that you would expect to find in this recording configuration. Cooling efficiency of the Thermalright Ultra 120 Extreme was compared under load conditions at stock speed to the Ultra 120, the Intel retail HSF and other recently tested CPU coolers.

X6800 Stock (2933MHz) LOAD Temperature

The Ultra 120 Extreme under load at stock speeds reached a maximum temperature of 32C. This breaks the old performance record just set by the Ultra 120 at 33C. This compares to the Tuniq 34C and the Cooler Master Hyper 6+ and Zalman 9700 at 36C, and is the best stock load performance we have measured at AnandTech with an air cooler.

At stock speed the Ultra 120 Extreme upgrade shows it is effective at lowering processor temperatures. The Ultra 120 Extreme was 1C cooler at idle than the Ultra 120 and Tuniq - our previous best performers. Under stress that improvement grows to 2C relative to the Tuniq while remaining at 1C compared to the current Ultra 120. With the Thermalright Ultra 120 Extreme providing the best in air cooling, we took a closer look at cooling along with overclocking.

    A lot is still never enough! In this case, I'm talking about having enough coolers, because I'm curious how my Thermaltake Blue Orb II would stand up against this crowd, and what sort of cooling upgrade the 120+ would be. I will have to find some of the other units in tests against the Blue Orb II and find out! Reply

    I was going to ask about the Thermaltake TMGi1
    It can be had for less then $29 plus shipping at newegg.com right now.
    I just got it and it is very quiet, keeps my hot Intel chip cooler then factory, and (big one) does not require me to remove my motherboard to install it.

    Being that there are no thermaltake coolers in any anandtech reviews I think it is time to add a couple.

    We have some Thermaltake coolers in for review. Some of these will definitely be included in our under $30 cooler roundup. Reply

    Is one of them the Thermaltake CL-P0370 ?
    That is tghe one I was talking about above but typed in the wrong info for the model number.
