CPU cooling issue???

[Tristan2034]

Lately my computer has been crashing a lot and I have noticed it happens almost always when my CPU reaches ≈ 75°C. To my knowledge that is not a vary high temperature but it is the only thing I can think of that is causing the crashing. I have a vary aggressive fan cure in MSI afterburner but I don't think that is helping much because my GPU usually never reaches a temp higher then 65°C 

 

Please Help. Thank you

I would check your thermal paste you only need a very thin amount. Thickness between a sheet of paper and a razor blade and covers the entire chip.

 

Make sure the plastic shield on bottom of cooler was removed and it is tightened down evenly.

 

I had a similar issue as you and ruled out the cpu temp as was around 70 when it crashes however when your cpu boosts it can spike the temp and cause the crash before you see it.

 

Your cpu should be thermal crashing around 100 degrees but if cooler is correct it will power and thermal throttle long before that. 

 

Another issue is if you use an AIO cooler or air cooler.... AIO (all in one /water coolers) are only reliable for 2 years and then you have the risk of pump failures or fins in the heatsink clogging. I recommend if you have the space to swap to air cooler which is more reliable. A NH-D15 Noctua cooler can usually be purchased online for between $40 and $80. The NH-U12S has same cooling but is slightly taller if you have high profile ram (ram with heatsink) or cpu is really close to it.

 

Hope that helps

Perfect thank you for all your help. I’ll take your suggestions in to consideration and see if it fixes my problems. 
 

Thank you

More information needed, please post specs. You can check event viewer for critical errors at the time of crashing, under system, filter for critical errors. If that's your max temps its not the temps. You can check temps with hwinfo64 and cinebench r23 / R24 for example. But check event viewer first.

Thermal paste spreads out. There's no "too much paste".

I would google your answer. Because you're wrong. Too much thermopaste can reduce your cooling efficiency because it has to transfer through the thermal paste. You only want enough so that it completes the surface across the c p u with the cooler in order to fill in any voids.

Find me some study supporting your claim instead of telling me to find one.

Could be a PSU issue. When the CPU uses a lot of power, it could make your pc crash if it doesnt get enough power or if the PSU is faulty
