This is mostly true, but there is one exception though: set PBO power limit to “motherboard” to allow the CPU to draw more power.
It will increase performance drastically, the only downside being that it gets hotter, but that should not be a problem with a cooler like that.
The default power limit is very conservative, so it works with even the shittiest of motherboards.
