Works well and easy to use
I put 8 of these on my DC DC battery charger in my camper van. Keeping the charger several degrees cooler than it was before. The adhesive bottoms work well. Seems like good value for the money. The small size also makes them versatile.

Good for small projects where you need to get rid of some heat.
Worked great to cool down some 2.5" USB drives I had. Got out the dremel and cut holes in the plastic casings and popped on a heat sink to the top and bottom of the drive and dropped the temps a lot.

Worked better than I thought it would.
I used these on the power pack for my laptop. I noticed it gets extremely hot. I added 1 heatsink to each side and the temperature difference was remarkable. It was actually cool to the touch.

Good quality
Exactly as expected

Sticky
Didn’t improve my temps while mining at all, but they are super sticky and look pretty cool

Great For Small Outboard SSDs
Just the right size for SanDisk Extreme Pro: 2 on one side, and 2 on the other. Only working with them on one side for now though. Helps keep drive running cooler.

Keep your stepper motors cool.
The size is perfect for standard size stepper motors, the adhesive didn’t require any prep work and has held on upside down in temperature fluctuating chamber with no issues. I used an extra to mount to pancake stepper that is moving all the time. Still holding like a rock. My stepper motors seem to keep about 8 degrees colder during peak usage. Great gain for the price.

Easy and appear to be effective
Attached to the back of the stepper motors on my 3D printer. I can feel more heat radiating off of the heatsinks than I could feel radiating off the motors without them. Temperatures taken of the sides of the motors are measurably cooler with the heatsinks installed. These are inexpensive and worth the investment if they extend the life of the motors or help provide more consistent results.

I was doubting they were going to work when I bought them, but I was dead wrong these work unreal the Y axis stepper motor was sitting at 51 degrees C and it dropped their temp down to 30 degrees C great purchase would definitely buy again

Habe mir die Kühlkörper für den Extruder meines Prusa i3 MK3s besorgt, da der Stepper-Motor gerade bei längeren Drucken schon gehörig warm wird. Ich war mir nicht sicher, ob die Wärme-Abfuhr ausreichend ist, da hauptsächlich aktive Kühllösungen mit Lüfter empfohlen werden. Aber: Es funktioniert einwandfrei, mit den Kühlkörpern wird der Stepper nur noch handwarm. Die Anbringung ist denkbar einfach, Motorgehäuse mit IPA säubern/entfetten, Kühlkörper aufkleben (Klebepads sind bereits angebracht), fertig.

Del kit di 4, ne ho attaccati 2 (uno per lato) ad un'elettrovalvola per CO2 per l'acquario che normalmente quasi ustionava quando accesa. Risultato ottimo, temperatura dell'elettrovalvola abbassata veramente tanto, con buone speranze per un'aumentata durata nel tempo.

I fitted these to the base of my ATEM Mini Pro. It was getting very hot. It now runs just with a slight warmth. Easy to fit, I used two packs and it will probably get me many more trouble free years out of the equipment.
