Here's the problem: with the turboboost turned off, downvoltting at -150 mV and standing on a cooling pad, the processor and video card are heated to 50 - 60 degrees (during the game), but there is still a PCH that is not cooled by the cooling system. As soon as the temperature PCH reaches 65 degrees, the coolers begin to rotate at a speed of 5000 rpm, which is very loud in the evening, when everyone went to bed. Since there is no cooling system on the PCH, there is no sense in such high speeds of the cooler. Wherein when PCH temperature reaches 63 degrees, NitroSense does not allow to reduce the cooler rotation speed, but only increase it. How can I forcibly lower the speed of coolers?
