My GPU is reaching 80C when playing games, is it safe?

[Charlise]

My specs:
INTEL CORE i3-4170 3.7GHz
ASROCK H97M ANNIVERSARY
GSKILL RIPJAWS X 2x4GB DDR3 1600MHz
PALIT GTX 750 Ti 2GB GDDR5 128BIT
KINGSTON 120GB SSD
WESTERN 1TB BLUE 7200RPM
CORSAIR VS450

Whenever I play videos on the internet it reaches 50C, and when playing games like GTA V, WoW, and other games, it reacher 80C - 85C, and sometimes it restarts on its own, what can I do to prevent my pc from restarting? Do I need to change the thermal paste of the GPU and the CPU? I believe it is the main cause, but I just want to make sure. Thanks guys!

Looks like an overheating issue, how are you cooling your PC?

First thing you should do is to make sure you havent overclocked it in any way and if you have, reset it to default.

Then make sure all your case fans and GPU fans are working and try playing games with your case side door open to see if the problem is just your case's airflow.

Seeing as how those are old components Im going to assume you got the PC a long time ago and havent dusted it in a while, get a can of compressed air and dusk the whole thing. Dust is the leading cause of overheating in old computers, and it is recommended to dusk at least once every 3 months to keep your pc healthy and happy.

Your last measure should be to remove the fans and heatsink from your graphics card and replace the thermal paste because it has probably dried up due to old age, but dont do this until youve done the other steps as its risky if you dont know what youre doing and voids your warranty if you still have one.

A general rule is that you dont want your GPU to go over 80c, even under full load, and its shutting down due to overheating to protect itself from damage. After doing these steps your problem should be solved.

Good luck, hope this helps.

Just plug and play. No aftermarket coolers for my CPU or GPU.

I'll try this Sir. Thanks!
