3705 Cooling Fan

This heatsink from Khadas is nicely engineered to fit their VIM3 (and apparently Edge as well). It comes with two thermal pads (one for each model) that can be cut to provide ample coverage for the SOC, RAM and PMICs. It's plenty to keep the VIM3 cool under light load, but if you're running sustained heavy loads you'll want a bigger one or one with a fan to avoid throttling and core shutdowns. This one is probably ideal for things like TV box/media center usage, where the CPU loads are not high and silence is preferable to ultra-performance.

You're thinking, instructions for what? Simple printout of where the heatsink tape ought to go (there are multiple chips, yet only two heat sink tape pieces, each a different thickness). Second, which screws are for which purpose. Was easy enough to figure out, but again, simple instructions on a small piece of paper would be helpful. Other than that, it is a nicely made piece.

heatsink quality is good, performance is great with this heatsink especially if you have a small cooling fan

Pros: Quite, helps the SOC under 70 degrees centigrade. Cons: None for what it was designed for

Easy to assemble and definitely needed as A311D gets hot
