Re: Heat sinks


I am using this with my Raspberry Pi Zero 2 W and it works well.

Has a built in heatsink.

The issue/problem is with a RPi zero 2 W overheating, whereas this case specifies that it is for a RPi 4. Totally different case requirements. However, this case DOES SHOW it is for a zero 2 W, and it shows a heat sink:

Maybe it will work?

have you seen the FLIRC case? 

It makes a marvelous heat sync, is quiet and looks good. 
The downsides of it is access to internal connectors requires opening the case, and the WiFi / Bluetooth performance suffers.

Maybe "up your heat sink" game:
Use a copper, rather than an aluminum heat sink. It transfers heat more efficiently.
Fins are only effective if you are using a cooling fan to move the air around.
Use thermal paste instead of a stick on pad.
