Enokay Raspberry Pi Single Cooling Heat Sink Review

A quality product (by the looks of it) with the added bonus of heatsinks for smaller chips. Since 2B I've been using solid copper fins on older RPi boards. Always questioned the need for a CPU fan, but this Enokay fan brought temperatures down even further. Best of all are two notable elements: you no longer have to leave the lid open to get a couple of degrees of drop, and the fan is thin enough to fit in with the lid closed.

I bought this fan to cool the processor on the Pi4. I am using a Pi4 on my 3D printer which does the job fine except the CPU overheats which slows down and stops the print job. Initially I set the fan to 3.3V and everything looked fine, but with large print jobs the CPU was still overheating. I ran it on 3.3v for a week then switched to 5v and was impressed that it was still relatively quiet. But it helped, there was no overheating. After a few days, however, I went to my printer and heard a…

I can't imagine anyone outside of the library not hearing this. Now let me teach you
