Easycargo 40mm Heatsink Kit 40x40x11mm + 3M8810 Thermal Conductive Adhesive Tape, Cooler Aluminum Heat Sink for Cooling 3D Printer Stepper Motor TEC1-12706 Thermoelectric Peltier Module 40mmx40mmx11mm

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.

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

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.

Good 3M Tape. Solid heatsinks.
