Samo je naravno poželjan top-down cooler (koji dolazi stock), radi hlađenja vrm-a, barem za heavy multithread

While all results are within random variation, two results stick out immediately. These are for Blender and Corona—two heavily threaded rendering applications. It looks like when watercooling is used, they're losing a lot of performance. This is also true to a lesser degree for KeyShot and Photogrammetry, which are multi-threaded applications as well.

The explanation is that the air cooler has the benefit of creating some airflow around the CPU socket, which reduces VRM temperatures due to it picking up some of the heat on the VRMs. Enthusiasts often use watercooling to maximize their cooling performance for higher CPU overclocking, which is the root of the problem. With zero airflow around the socket area, VRM temperatures just keep climbing, which activates some safeguard that slows down the CPU to avoid physically damaging the motherboard, CPU, or other components.
