Review on 🌬️ Simple Deluxe 2-Pack 80mm Quiet USB Fan with Multi-Speed Controller for Enhanced Cooling Performance - Ideal for Receiver, Router, DVR, Playstation, Xbox, Computer Cabinet Cooling by Jose Haskin

My 2013 Mac Pro's idle temperature dropped 2C to 3C, not a big deal, but the heatsink did a good job of keeping the temperatures within reasonable limits when I ran a stress test (Unigine Heaven ). There are no instructions in the kit, but they are not needed, installation is quite easy. I had to remove the warranty sticker to ensure it made proper contact with my M.2 NVME, which didn't excite me. I saved the sticker by sticking it to a piece of wax paper (to make it easy to peel off if needed) and putting it in the box the heatsinks came in.
