[flairclapper]

I built my current pc around 3 months ago here are the specs

5800x

3070ti

msi b550 gaming plus 

32gb ram 

nzxt h510i

msi mag coreliquid 240R aio

This was running fine for 3 months 3 days ago i noticed my frames cut in half and my temp just sitting at 91 celsius so i bought a new cpu cooler the fuma scythe 2 cleaned the old thermal paste and applied the new one 

but im still running 91c in game and while idle it sits around 65-71

I undervolted my cpu my motherboard is up to date i dont know what else to try

Completely revert everything you've done to the board. Better yet, clear the CMOS and start fresh. If the PC was given to me, i'd re-do the thermal paste application and more importantly the cooler mounting myself then boot up and run only HWInfo or Ryzen Master for checking temps. 

 

Regarding the MSI AIO, those are dying weekly around here, absolutely terrible unit so no surprise there. The FUMA 2 on the other hand is a very competent air cooler. 

 

You have two likely scenarios and another very unlikely scenario. First, your mounting method and airflow is extremely bad. 

 

Second, a sensor onboard the die is bad. This is very unlikely.
