PCを自作する際に、CPUを簡易冷却する目的で購入した。 電源を入れてからBIOSが起動するまでの間、CPUファンの代わりに本製品をのせて冷却したけど、わりと発熱を吸収できた印象だった。マザーボードからも特に警告は出なかった（何ものせないで起動するとマザーボードから警告が出る）。ちなみに試したCPUは「Ryzen5 5600」でTDPは65W。 マサボとCPUの起動テストする際に、毎回CPUファンをはめ込むのが面倒なら、本製品で代用できるんじゃないかな。もちろんOSまで起動と発熱が増えて本製品の冷却力では手に負えなくなるので、使用するならあくまでBIOSの起動までに止めるべき。 自作PCをする人にお薦めだと思う。

This heatsink is really impressive for the price. I've used several different heatsinks, but when this one was first delivered, I was surprised by how clean and well-finished it was. There were no rough edges or scratches, and no blur around the edges either. A lot of Chinese-made heatsinks tend to have unfinished edges or sharp spots, but this one is exceptionally well-made. On top of that, the price is very reasonable. I'm using two of these on NVMe enclosures with thermal pads, and they do an excellent job of transferring heat. Even without a fan, the setup stays clean, efficient, and the color matches perfectly too.

Did the job of keeping my 3090 cooler as they run very hot

Just what I needed, excellent quality.

Works like magic. My 3090 is now 10 Celsius degree cooler after I used two of these (need good thermal pad between them).
