I was looking around for an heatsink for the RaspberryPi 4, and I found something "bulky" like this: https://shop.pimoroni.com/products/rasp ... 4-heatsink
Would be maningful to have instead just a fan, maybe SMBus controlled, to smoothly working only when needed? I wonder if exist something, like a rig to mount when I need to use 4K60p or the like. Because I think is cool to see the SoC package naked

Does exist something like that, or the reason why I don't find it is because no one would use it?
Cheers,
