I really enjoyed the Noctua UH-12A review, but it leaves me with a question I've asked a lot in the past several months. Many versions of the venerable Noctua UH-12 are similar to a cooler no longer in production: The Thermalright Ultra Extreme 120 (aka the Thermalright TRUE 120). The cooler was introduced in 2008; this may make it seem very obsolete, but I recently contacted Thermalright asking for the heat dissipation specifications, as I have a TRUE Black 120 (which is the TRUE Rev. C with anodizing). They replied to me quickly and rated it for a massive 240 watts, unheard of back when this cooler was released. With that in mind, I decided to take the plunge in migrating it from my 4.4GHz (constant max turbo on 4 cores) i7-4790k to my new i9-9900K, which I'm running at 4.8GHz (constant max turbo on 8 cores). Under 100% load on all eight cores (Folding@home) with a similar load on my two Geforce GTX 1070 cards in the same case (Corsair 650D with the add-on mesh side panel, two 200mm intakes, 1 230mm + 120mm exhaust), with two Noctua 120mm 1300rpm (constant-speed) fans in push-pull, no core goes above 80C. I'm very impressed. I continue to be curious how this would compare to Noctuas NH-U12A, NH-U14S, and NH-D15S. I really wish someone could dig up an old TRUE to check on this. Heck, I'd be willing to lend mine temporarily, since I've got an NH-D15S sitting here in box. I'd just really love to see how an 11-year old top performer rates after all this time when compared with the latest top-end gear.
