During idle temp is around 35C. CPU fan at around 600rpm. Even the case fan stops with fan xpert2 silence profile.
Now, with prime95, the temp goes up to 80-90C with the fans at its max speed (around 1300rpm)
Pretty noisy and hot i think.
I did the in-place large FFT one.

I have 2 fans on the heatsink. the one on the rear is about 1cm from the case rear fan.

Should I remove the rear fan on the heatsink?

Please dont tell me I have to re-apply the thermal paste or the cpu is not good

keep both fans on, now idle temps are good but load temps.....That's not good, and no-one can say that that is fine, because 80-90 degrees is outrageously hot for a un-Overclocked cpu.

Your nightmare has come true, you will have to re-apply thermal paste, and if that is a same outcome, your CPU cooler is defiantly faulty.

I took a deep breath and took them apart. Re-applied the paste, and removed the rear fan on the cpu cooler. It felt too close to the rear case fan.
The temperature didnt change much. Max stress with prime95 and it goes up to 90 degrees.

Which is more likely to be the problem. CPU or the cooler?

 

[unknownofprob]

the whole cooler, as it shoudl not do such a bad job at cooling, you'll have to get it replaced or get a different one.

Bad meaning its not making clear contact to the cpu?

 

[unknownofprob]

basically, it could be due to fan RPM, blockage, who knows.

I replaced the cooler with the stock one. Now, the temperature gone up so high the cpu throttle down to 3.4-3.5Ghz. Contacted the seller and will probably end up replacing it.
The GPU is coil whining. One of the cable on the PSU has problem. My plan on playing games during the weekend just ended up so bad

Did you apply the thermal paste correctly? If not, I'd suggest looking at a tutorial on youtube or something.

I think I did. Uesd the pea method the first 2 times with Noctua cooler.
For the stock cooler I just used the paste that was on there from the beginning. I know its not the best but it should at least cool the cpu enough so that it wouldn't throttle down right?
