4PCS 40mm Aluminum Heatsink 40x40x11mm Thermal Tape

Sticks pretty well to my motor, and kept it cooler around 5°C. Definitely a remarkable little accessory for your printer. It fits almost every 40mm sized stepper motor and that is what I like most about it.

great thing to help cool my stepper motors.

Slapped two of these things on a 2TB Samsung T7 that I'm using this external storage on a PS5. The T7 is notorious for running really hot, much hotter than its predecessors. I picked these up thinking they would help avoid throttling. And they do. They spread heat easily and definitely helped to improve sustained performance. I see it in download and transfer speeds 3/4 of the way through. The T7 used to throttle like crazy near the end of a long download. It just doesn't now. Worth considering. Just be careful where you stick these things. Getting them off is a pain (use dental floss).

These are good quality heatsinks. Be aware that the supplied mounting tape works but doesn't conduct heat very well. You can greatly improve the heat sink effectiveness by skipping the tape and using thermal paste instead.

I have a 4k DVR with front and rear cameras on my motorcycle. The DVR will overheat and stop recording after a while, so not to damage the unit. I bought this and put them on the DVR and no more overheating. The adhesive is strong, (I have a Harley that vibrates as a Harley should) and all the pieces I add to the DVR are still intact. Good product, I strongly recommend!

Saw a few ROG Ally videos and came across this mod for the SSD. This heatsink does work and it did improve the FPS; however, if you are using this heatsink for the SSD, you will need to file down a corner near the GPU heat pipe to avoid damages to it during reassembly.

As advertised. Would buy again.

Used on a fanless mini PC. Works well to keep the mini-PC cool. The adhesive appears to work well.

Good product seems to work ok for my application

Swiftly delivered and fitting a handheld.

These little heat sinks are incredible for lowering the temps on a sealed industrial fan casing. Temps were 90° C but after applying 6 of these aluminum heat sinks to the top surface the temperature decreased by 12° C.

I use these little heat sinks on my RTX 3090, a card which has high memory temps. I changed the stock thermal pads and thermal paste on my card which dropped my temps by about 10 degrees C. With these heat sinks I managed to drop my card temps by another 2 degrees C. With a small cheap fan i can usually manage to drop my temps by another degree C or so. These heatsinks slow down the process at which my card heats up but not dramatically as they do get saturated rather quickly, especially with this card. When ambient temps are lower they work more efficiently as dissipating the heat with the help of a small fan. I had bought one pack and then 2 more and in retrospect buying copper heatsinks would have been better but I'm not disappointed by these heat sinks at all. Just remember to be realistic when its come to what your expecting in terms of efficiency. For the price I doubt that I could really get better.
