CPU Cooling Test Configuration

The test setup was exactly the same as used in the recent Thermalright Ultra 120 review. All the components of the test bench remained the same.

Since Thermalright provided a syringe of their own thermal compound, the Thermalright compound was used in mounting the Ultra 120 Extreme, just as it was used in the Ultra 120 review. For more details on the specifications, weights, and installation please refer to the Thermalright Ultra 120 review. As already stated, the Ultra 120 Extreme is the same exact cooler with two extra heatpipes.


As you can clearly see from the installed photos, the Ultra 120 Extreme is the same dimensions as the Ultra 120. Nothing is really any different with 120 Extreme install except for the issues with fitting a Socket 775 adapter through the pipes with extra heatpipes in the way. Hopefully Thermalright will have solved this issue by the time you can find retail Thermalright Ultra 120 Extreme heatsinks for purchase.

To be blunt, not too much was expected with the Ultra 120 Extreme. Six heatpipes instead of four is nice, but how much could two added pipes really do for a cooler that was at the top of our performance charts? As you will see in our performance results, assumptions should always be tested. There was certainly a surprise for us in the Ultra 120 Extreme cooling and overclocking performance.

Fanless Cooling and Noise Levels

Since all testing used the same S-Flex SFF21F 120mm fan used in the Ultra 120 review, we did not retest noise levels. Noise levels will be exactly the same as the excellent results posted in the Thermalright Ultra 120 review. Please refer to that review for information on the Ultra 120 Extreme noise levels.

The Ultra 120 also was useful as a fanless cooler, as demonstrated in that review. However, our current cooler setup is not ideally suited for testing fanless CPU coolers, since we do not have a downward facing fan or additional rear exhaust fans to assist the fanless cooler. Refer to performance charts for fanless cooling in the Ultra 120 review. Results with the Ultra 120 Extreme should be even better with the extra cooling provided by the additional heatpipes in the EXTREME design. Improvements in fanless cooling should be similar to the cooling improvements seen in this comparison of Ultra 120 and Ultra 120 Extreme cooling with the same S-Flex fan.

    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
