2Pcs Black Aluminum Heatsink 100mmx25mmx10mm/ 4x1x0.4 Inch Heat Sink Cooling Fin with Pre Thermal Conductive Tape Heat Sinks for Cooler Electronics USB Expander Led Phone Power Charger

My thunderbolt USB drive was overheating and this solved the problem! With the provided adhesive tape I was able to glue the heatsink to the USB drive, and the temperature stayed at least 10 degrees lower.

Bought these to put on a ham radio transceiver that gets hot when transmitting (mcHF). The thin thermal pad on each heatsink works well, holds to the metal case and the sinks get just as warm as the radio case, indicating good heat transfer.

Great strong adhesion. I ended up going w/a different solution bc I needed a shallower heatsink, but that was my issue.

Arrived on time as described . Adhesive stuck immediately. I ended up strapping a fan over it so it will unlikely ever fall off. Fit perfectly for my modification project. Would purchase again.

Excellent finish.Adhesion could be better and the blue tape should be thinner for better heat conductivity.A good product.

This is a decent basic-level heatsick for electronics. I was expecting better performance overall as the PC card I'm using it on still runs very, very warm, but I've attached two (2) of these heatsinks to the top and bottom to help with heat dissipation. I may attempt other heatsinks on the market, but for the price, this was a decent purchase.

Perfect size for my Roku receivers, and really seem to be dissipating the heat from them.

My Roku stick was always really hot and occasionally acting weird. I stuck two of these on either side of it and it seems to be helping. Tips: Clean the Roku with isopropyl alcohol first to get better adhesion, and don't stick them too close to the HDMI connector since on some TVs that may make it difficult to plug the stick into the TV.
