GPU TEMP really high

[condog209]

Hi my r9 280x  is getting really high temps for some reason 
right now idle is 55 C with fans at 30% 
normally the idle is 50 C with 30% 
and i started to get back onto wow my gpu temps was starting go over 80C 
any suggestions

The heat sink is most likely just dirty, give it a good cleaning.

Use compressed air to remove any dust that could be clogging the fans.

Cleaning could help and check if the fans work properly. Does your case have enough airflow?

my back exhuast fan went out 

 

[Walkure]

Check your case airflow, make sure there's adequate intake and exhaust fans.

 

Also give your gpu a good dusting with some compressed air, while you're at it give your case a cleaning too.

 

And if neither solution improves the temps much, replace your GPU thermal paste
