40mm Heatsink for 3D Printer Stepper Motor Thermoelectric Peltier Module TEC1-12706

Product as described - sticker even last in very high temperatures

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.

Used to add some degree of cooling to a bare motherboard VRM . Easy to install.....and they get very hot so they are obviously working well. The thermal tape is already pre-applied to each heatsink so no cutting to do. Make sure you press them firmly down and hold them for a while to make sure they stay stuck on! Nice colour too.

fitted 2 of these to mk3s printer motor (filament gears) reduced temperature by over 5 deg. also fitted 43mm motor on top of the top heatsink( just in case) keeps temp stable even through 18 hr print

Good little heatsinks i use them on stepper motors adhesive is strong too and dosent seem to impact the cooling. Also come in a nice little bag

Very good. Effectively reduced my stepper motor temperature by 12 degrees. Not bad for passive cooling.
