🔥 Kalolary Aluminum Chipset Heatsink Radiator Cooling Fin (2 Pcs) - Effective Heat Dissipation for CPU, LED Power, and Active Components Review

These heatsinks are great for my 3D printer stepper motors. I like the extra surface area of the fins compared to the dedicated stepper heatsinks I've found elsewhere. I drilled out the centers and installed these radiators with thermoplast.

Great little heatsinks. I had to replace the doorbell transformer and the new one got very hot. I attached them to it and now it works nice and cool

This is really great for 40x40mm peltier modules. but for real heat dissipation from the system, larger Peltier blocks of 63 x 63 mm are required. and probably TWO of them on the same heatsink. We need larger COPPER cooling blocks, at least 64 x 64mm x 14mm thick for one Peltier element and 64 x 130 x 14mm for two 63mm diameter Peltier elements. Unfortunately, aluminum actually acts as a thermal choke, reducing thermal throughput by as much as two-thirds.
