In this way I get stable rpm on the fans and a more than satisfactory silence. To 'buffer' the problem the only solution found was to set clock the CPU, from the BIOS I set the base clock speed to 100 and the 'multiplier' to 40 (I don't know if it's still called that, I did school on an old AMD Athlon Xp) and disabled the Core performance boost.īy doing so I get all the cores locked around 4 Ghz stable (remember that it has a base frequency of 3.6 Ghz) without going to set different voltages. Going to investigate, I realized that this depended on a bizarre management of the frequencies on the different cores that were continuously raised and lowered, thus giving temperature peaks and consequent rpm increase. Let me explain better, during the normal use of the PC, the rotation speed of the fans varied suddenly, slowing down and increasing the speed regardless of a more or less intensive use of the CPU.

I get to the point immediately, for about a year I have been the owner of a ryzen 3700x (complete configuration below), I immediately noticed an anomalous behavior in the ventilation.
