Heat Sinks for GDEmu clone?

[ItalianGrandma]

So, when I got my GDEmu clone, it came with the plastic tray and the SD ribbon extender. I either damaged the ribbon cable trying to install it or it was broken from the start, so I ordered new ribbon cables. The new one works, but it doesn't fit in the slot so I may have to file it down.

I'm considering just not doing that and getting heat sinks for the gdemu instead. Does anyone know what size heat sinks I need if I go that route? For that matter, are the heat sinks really necessary if I'm not using the plastic tray?

Some additional info: I'm using the stock PSU with the 12v regulator removed and I still have the stock fan.

The Gdemu it's self makes no heat. If you don't have any random reboots it should be fine as is.
