In the test 15 years ago: Thermalright's Ultra-120 Extreme was the reference

Although Thermalright had an excellent cooler on the market with the Ultra-120, inexpensive and excellent competitor models such as Scythe made life difficult for the manufacturer in 2007. The counterattack followed with the Thermalright Ultra-120 Extreme (test), which took cooling performance and price to a new level.

A monster with six heatpipes

Thermalright didn't do things by halves with the Ultra-120 Extreme: The 790 g (without fan) heavy cooler with dimensions of 63.5 × 132 × 160.5 mm (L × W × H) was equipped with six U-shaped 6 mm – Equipped with heat pipes. Compared to its predecessor, there were two more heat pipes that dissipated the heat from the copper base plate to the aluminum fins. As usual with Thermalright, the cooler, which costs around 50 euros, did not come with a fan, so users had to purchase a suitable 120 mm model as well. Fans could be attached to the nickel-plated cooling tower on both sides using a wire bracket.

Fan attachment with wire bracket, not ideal because it's a bit wobbly
Wire bracket mount does not allow every fan installation
Screw connection with spring screws ensures high contact pressure

The assembly of the Ultra-120 Extreme turned out to be largely problem-free – as long as there was enough space available. Due to the expansive dimensions, the cooler tended to collide with all sorts of other components. Mainboards with protruding coolers as well as cases that didn't offer enough space for a 161 mm high cooler caused him problems. In addition, a special backplate had to be purchased for some ASRock and Gigabyte mainboards that were not delivered with the AMD standard backplate Peak performance in three scenarios

The Ultra-120 Extreme cut an excellent figure on an Intel Core 2 Extreme QX6700 with four cores each running at 2.66 GHz. In the test 15 years ago, it competed in three different scenarios with different fans. The 120mm low-speed reference fan was a Scythe S-Flex SFF21D at ~750 rpm, a Papst F2GLL at mid-range at ~1,140 rpm and a Sharkoon Power at ~2,100 rpm at high-speed. at least In two out of three of these configurations, the Thermalright Ultra-120 Extreme took the lead in the test field. In the third case, the high speed range, it was beaten by 0.25 Kelvin by the Zalman CNPS 9700 LED, which, however, was equipped with a different fan due to its design. The next-placed cooler with the same fan was the Xigmatek HDT-S1283, which was beaten by 0.5 Kelvin.

Conclusion

The Thermalright Ultra-120 Extreme gave little cause for criticism. The processing was excellent, the cooling performance was unbeatable and the design was simple and elegant. Everyone had to decide for themselves whether the comparatively small advantages compared to a significantly cheaper Xigmatek HDT-S1283 or Scythe Mugen justified the surcharge. In October 2007, anyone who didn't want to compromise on cooling performance (given money and enough space) couldn't buy a better air cooler than the Thermalright Ultra-120 Extreme.
