Wouldn’t use that PSU for anything. Time for a new QUALITY unit.
 
there is no telling what the problem actually is. What in the world in your computer is over 104C?

As far as the PSU, even brand new I wouldn't put that thing close to a computer. After 3 years, that thing is ready to destroy your components for sure.
You need to look into getting a quality Corsair, Seasonic or EVGA unit if possible.

actually i just checked the psu with a multimeter,the 12 v read at 12.38v which is perfect i have never had any issues with this psu and computer since i built it in 2016,also any oof those psu's would cost me between 70-200$ here in my country :( anyways thanks for your input
 
Your computer would be off if the PSU provided 5.8V on the 12V line.... a false reading nonetheless.
I see that you've already checked with the multimeter... 12.38V is within the spec of the +12V rail.
+12V atx spec is between +11.4 and +12.6V.

Also the other temp readings(temp3, temp4, temp5) seem flawed.

EDIT: I researched your PSU and from various forums(johnnyguru) nox is marketing 450-500W very cheaply made units as 750W "reliable and efficient" units. They are usually lying on the efficiency rating too, even though their models are rated 80+ bronze they do not meet the standards required for their acclaimed rating.

Even though your PSU might be fine for now, I highly suggest that you upgrade to something better in the future.
If you want some recommendations, just post your full system specs.
