Performance at 2200MhzLet’s start with the CPU at stock speed and voltage; I’ve grouped the results in two “noise” divisions. Since most rooms have a 30-35dBA ambient noise, anything below 40dBA can be considered as none disturbing and silent to most people.
While those heatsinks which measured 40dBA can be heard clearly when you are in the room.
Performance at 2200Mhz – Passive CPU CoolingCooling a modern CPU without active cooling can be quite a challenge; there are not a lot of heatsinks out there which can pull it off. Those who can we compare here in this chart:
