Heat Sink Cooling Module Aluminum Heatsink Cooler Fin (3.9" x 2" x 1.2")

This is a nice piece at a great price. I used it to mount my 4 pin gm hei module on ; for an ignition conversion for my 440 big block chrysler. It saved me from smoking another module

Fits perfectly on top of a little usbc Mac doc that I run dual 4K though and all my usb stuff. Much cooler now

Very effecient! I use them on gopros which usually overheat in the sun in about an hour. I can run one all day with this attached to it

Just as ordered.I used heat transfer tape to increase heat removal from my charge controller.

Good product for the price. Fast shipping

Works great for my ac dc rectifier in my welder

Exactly as described.
