Review on 💻 Nxtop Computer Aluminum Heatsink Radiator by Lild Zimmerly

I don't have the tools to measure the thermal resistance of these heatsinks to air, but if you look at them you can see that the fin area is large enough to transfer heat from the heatsink to air. The base is thick enough to disperse heat across the fins and help with transient heat in the object being cooled. Those are good sinks.
