120mm Large Heatsink Aluminum Heat Sink 4.72x4.72x0.79Inch/ 120x120x20mm Square Cooler for Router Cooling Base and Power Supply IC Graphics Card Memory Heat Sink 120mmx120mmx20mm

I bought this for my Aiyima A07 Max amplifier. During the summers, the ambient temperature in my area reaches 30 degrees Celsius, and (consequently) the amplifier gets pretty hot. I just zip-tied this to my amplifier with some Noctua paste, and now it's happily running lukewarm to the touch.

This is a nice large heat sink. The back side is smooth and flat, nicely machined.The fins are consistent. The edges of the fins have a slight sharpness to them, but that doesn't matter much.I'll be cutting it down a little and attaching a small heating element. It will heat some LiFePo4 batteries.

熱々のミニPCの下にこれを取り付けて風を当てるとよく冷えます

かなり軽いヒートシンクですので、熱容量は少なめかと思います。今回の使用用途ではすごく使いやすかったです。

WiFi接続は関係なく、音響製品で発熱が気になる所に使用しています。
