Large Aluminum Heat Sink 2.71"x2.71"x1.41"/ 69x69x36mm Heatsink High Power Cooling Plate 27 Fin Radiator GPU Cooler IC Module PC Computer Led PCB Charger Electronics Amplifier

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.

私のゲーミングノートPCの電源アダプターは240wで、動画エンコードや動画のアップスケーリングなどを行い負荷をかけると、手で触れられないほどの発熱をしてて、これは良くないと思い、本製品を2つ購入。 電源アダプターの上面と下面にそれぞれ本製品を置いたところ、触っても「温かいな」くらいの温度になるまでうまく放熱してくれてます。ちょうど大きさもぴったりでした。 同じ感じで高温に悩んでる方いらっしゃいましたらこの商品はおすすめです。

For $8 dollars delivered it's pretty nice. Very smooth face, fine fins that actually serve to dissipate heat, fine end cuts with no jagged edges, just the right size. Unless you absolutely need something actively cooled with heat pipes or skived copper: this is your clear winner for intermediate size, high quality, passive aluminum heat sinks. Just be sure to arrange the fins vertically so you get a little convective cooling boost from warm air rising.

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

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