FAQ
Do I really need an AIO for the 8600G?
No, an AIO is unnecessary for this APU. Compact air coolers are more than sufficient and save significant space inside your chassis
Will low-profile coolers interfere with my RAM?
Most low-profile coolers are designed to avoid RAM interference, but always check your motherboard's socket layout and memory height before purchasing
Is the stock cooler enough?
The stock cooler is functional but loud. Upgrading to a premium low-profile air cooler significantly improves acoustic comfort and thermal headroom
