## Description

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.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 used in Computers GPU HDD etc., for Power Transistors, FETs, ICs, Power Amplifiers, Wifi Routers, Voltage Regulators, MOSFETs, SCRs, FET, IC etcHeatsink Features：Size:2.71" x2.71" x 1.41" /69 mm x 69mmx 36mmMaterial: Aluminum 6063-T5Fin: 27Color: Silver Weight: 6.13 ozQuantity: 1

Review: 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。
Review: 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.

## Features

- 1. Product Name: large heat sink ( anodized aluminum heatsink); Material: aluminium; Color: sliver.（Sufficient materials only for excellent quality）
- 2. Size: 2.71 x 2.71 x 1.41 inch / 69 mm x 69mmx 36mm (L*W*H)
- 3. The Quantity of fins: 27pcs; Base board thickness:4.6mm, Fins board thickness:0.6-1mm; Fin spacing:1.99-2.12mm; Fin height: 31.4mm; The fins increase the area of the board and thus provide for greater heat transfer.

## Questions & Answers

**Q: I’m looking to cool a couple of thick film resistors that keep overheating. Can I cool more than one (2) with this heat sink?**
A: I would think so. It depends on how much power they are dissipating and how much airflow is on the heatsinc

**Q: Is this anodized?  Also what is the alloy?**
A: It's very shiny which might lead one to believe that it has been clear anodized because it doesn't have that dull grey look of raw aluminum that's been left out for a while.  I have no clue about the alloy.  The packaging says nothing about the finish or the alloy.

**Q: Can you make anodized 200 x 138 x 36mm block? Thanks.**
A: Hi
69x36mm HeatsinK, already all silver oxide item surface, you can use two side by side to dissipate heat for electronic products, thank you

**Q: What is the thermal resistance of this heat sink in the 400mm version?**
A: Short answer:  About 0.4 oC/W/16in (still air). For others who purchased a different length, they will need to adjust this number. 

From my review below, a more detailed answer: 

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.
