item update
According to customer's suggestion, the surface of this product has been oxidized
After optimization:
the surface is smoother and more suitable for applying thermal grease, and the heat dissipation performance is also improved
Different Lengths
Why Choose Awxlumv Heatsink？
1. Good material, sufficient material, excellent quality.
Thick enough base plate, sturdy fins, they are not easy to bend,more conducive to the improvement of the cooling effect.
2. Anodized! flatter cuts, less scratches and burr-free appearance.
In fact, many sellers omit the anodising step directly in order to save costs.
Scenarios of use High Power Heatsink 1
- Made of high quantity aluminum, good thermal conductivity.
- Reduce the risk of hardware failure due to overheating.
- Designed to maximize its surface area in contact with the cooling air.
- Light weight and used in applications where weight is a big concern.
- Widely use for computer, power IC, power electric device, LED light devices, etc.
Scenarios of use High Power Heatsink 2
The Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as light emitting diodes (LEDs), where the heat dissipation ability of the component itself is insufficient to moderate its temperature.

レノボのThinkPad ユニバーサル Thunderbolt 4 ドックの冷却に使用している。上側だけでも良いが、せっかくなので下側にもしくために追加購入。乗せるだけでヒートシンクに熱が伝わりいい感じに冷えているので、さらに追加購入予定。本格的にやりたい場合は熱伝導粘着テープを使えば良いが、剥がすのがかなり大変になるのでこれで十分。

Lots of surface area...Gotta make your own mounting standoffs to keep up and air moving all around...works well

This is a great little heat sink it has great heat dissipation. If you are using a cooling fan the air flows through easily. There is plenty of cooling power. 👍

The glue works great. I stuck two onto a large planer LED light's large aluminum back plate and directed a fan onto them. It runs pretty hot at full brightness. It ran much cooler and probably lowered the IR output quite a bit with the heat sinks. I might put another one on.

ホームルータを５G対応のホームルータ(Docomo 5g home hr02)に替えたところ、ルータの温度がずいぶん上がった。といっても、手で触って丁度良い湯加減か少し熱い風呂に入っている程度。しかし、これまで使っていた４G対応のホームルータ（PIXELA pix-rt100）ではそんなことがなかったので、少し気になります。Docomoのこのホールルータに関しては、同じように気になっている方も多いようで、ルータの外にファンを付けるなど色々と工夫されているようです。もっと簡単にできる方法として、私はヒートシンクを試してみることにしました。本ヒートシンクはサイズも丁度よくホームルータの頭に乗っかり、とりあえず紐で固定するだけにしました。ヒートシンクそしてルータ本体を手で触った感触では、自宅の５０インチ液晶テレビの裏面を手で触ったときの温感より確かに下がっていました。

My phone gets pretty hot when I'm charging it, this dissipates the heat really well. Put some rubber feet on it so it does not scratch the furniture, but I think a dab of silicone would stay on better. This size matches my phone really well while the camera bump hangs over the edge.

I have a 12 Volt 10 amp heavy duty power supply to replace all individual power supply's that feed part of my network setting and a 4" computer fan to keep it cool and prolong it's life but the noise was quite annoying and had to replace it often.Decided to add a big aluminum radiator adhered with thermal tape to the power supply aluminum rear back plane as to have only convection cooling and yesss it worked absolutely great, now the power supply is barely warm and zero noise.Besides the problems I had with the thermal double side tape lack of enough adherence, which was unable to hold the radiator on it's place and force me to fabricate 4 steel holding brackets , once I installed the brackets now I am absolutely relieved of any overheat problems !!!!

The fin count and fin aspect ratio of this heatsink is impressive, especially to us old-timers that remember a time when heat sinks with this high a surface-to-volume ratio had to be made by edge-embedding sheet fins into a milled-slot carrier.I found a dimensionally-similar (2.581" wide instead of 2.71", 1.340" tall instead of 1.41" tall) heat sink in an online AAvid catalog, model # 83220. The AAvid heatsink specs were 1.01 oC/W/3in (still air), so I'm expecting this heatsink could be 10% better (lower). Note that if you bought a length other than 3", the thermal resistance does not scale linearly with 1/Length, assuming a centrally located thermal point source. For the 15.75" length I'm using, the improvement is only a 50% reduction in thermal resistance.Also note that the thermal resistance decreases (improves) with moving air. While the documentation I found for the #83220 did not provide thermal resistance versus air flow, I found another AAvid catalog and heatsink #72070 (dimensions 3.008" wide, 1.02" tall, similar fin aspect ratio, 1.4 oC/W/3in) that provided a thermal performance versus airflow table; for a modest airflow (quiet muffin fan) of ~700 LFM, the thermal resistance drops by about another 70%.Net result, for the 15.75 inch length option, operating with 700 LFM forced air flow, is expected to be about (1oC/W/3in * 90% * 50% * 30%) = 0.14oC/W. My heat source is distributed along the 15.75" length, rather than being a point source in the center, so I expect the actual performance to be 2-3x better (lower resistance) than the above calculation.One final note, the fins on these heatsinks are thin and quite prone to bending, especially the outermost vanes. These arrived well-packed in foam sheets inside a custom-sized cardboard boxes, and only one of the four I purchased required any straightening of the fins.
