Just curious if it going to overheating or not under moderate to heavy OCing and why ASUS didn't bother to put it on just like in the PRO model?

Most of the heat in those mosfets is internal, gets dumped into the ground plane, part of the reason why monitors like HWInfo also monitor motherboard temps. By adding a heatsink, you also offer the mosfet a way to siphon heat in a different direction. Out. The heatsink does 3 things then, offers window dressing, helps cool mosfets, helps cool motherboard.

But if it's not heavily depended on its usually not necessary.

So higher grade boards have larger heatsinks, made to take more abuse.

Surface area is surface area, and there's only so much that can be done with heatsinks that sit under aircoolers, next to ram, above pcie slots etc. At some point its going to be on the user to find a solution to better cooling, such as a fan.

well, fins are better than squares. and mobo vendors rarely if ever do propper fins.

most are just slabs of aluminium that look nice more than they actually cool anything.
