Heat sinks

 

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.

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. ?

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?

It comes with two interchangeable tops. One has a higher clearance to clear a heat sink, but it doesn't include the heat sink.

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

Has a built in heatsink.

I too used some thermal grease.

Copper has about 40% better heat conduction, but the heat sink to air conduction is about the same so with the small size and large surface copper vs aluminum won't make much difference. Also, it can be really hard to find copper heat sinks.
