Review on Nxtop Aluminum Heat Sink Module Cooler Fin for High Power LED Amplifier Transistor Semiconductor Devices (100mm x 69mm x 36mm) by Brad Schillings

Bought this radiator for non-traditional use. I heat the case with a peltier peltier element and use this heatsink to transfer the inside temperature of the case which is measured by sensors outside the case. I painted the surface of the heatsink with a special IR absorbing black (emissivity around 1) so that the sensors measure the temperature accurately. The fins face inwards and the internal temperature of the case heats/cools the fins of this heatsink. The cooler works great, the edges are clean on all sides (no burrs). would recommend.
