Hello, good afternoon, I have a Ryzen 7900x3D with an Asus STUF x670E-plus motherboard and after updating the Bios to the latest versions that according to Asus improved the performance of the new CPUs, the packcage in maximum use went from 68 degrees to about 88 degrees of peak, with the maximum temperature of these CPUs being 89 DEGREES, it increased by about 18 degrees after updating the Bios, I tried previous versions and it was still the same, apparently only with the factory one I did not have those problems.
Another problem that it has is that the VRM at rest is at 53 degrees and the CPU package is at 50 degrees at rest too, I have it with a 4090 that in maximum use it does not exceed 60 degrees or 70 in Hot spot, I have tried to use it in games and the temperature of the cpu and the vrm does not exceed 60 degrees, but I am concerned that without using it it would be around 50 degrees at rest... although later in games, which is what it is for I am going to use it, it does not reach critical temperatures.
I have it mounted on a corsair 7000D tower with 12 fans at maximum 1800 rpm, the rpm curvature adjustments are set so that at 60 degrees they all work at 1800 rpm to avoid component deterioration, the other components are M.2 ssd and RAM style ( with OC at 6000mhz) etc... none go above 50 degrees in maximum performance, the only problem that the motherboard is giving me after updating is that it is at 50 degrees with all the good cooling it has and the vrms too , and sometimes when I open a new style browser to open YouTube it goes to 60 degrees for a few seconds...
The PSU is a 1000w Gygabyte UD1000GM PG5 (rev. 2.0)
The 2X16G Kingston ddr5 with EXPO profile for Amd at 6000mhz (it has two profiles and I put the first one that leaves the voltage at 1.35 if I remember correctly)
