Remove dust.

All the fans were recently installed and when I did this I thoroughly went through everything and removed the dust. I'm pretty sure that's not the problem.

Could possibly be the thermal paste on the gpu then?

What GPU is it?

>>54552000
GeForce GTX 770
I believe it's from EVGA

>>54552055
EVGA stuff is usually pretty decent and long lasting I think.

Might be worth checking the GPU fan's performance first though, so open it up the side of your pc's case and see how the fans handle themselves during some highly intensive tasks.

So long as it's not above ~85 it's absolutely fine so you might not need to worry too much.

(85 degrees celsius I should add, though 95C is also a good limit of sorts)

I just installed Afterburner, I'm going to see if it does anything funky..

I'll report back if anything goes wrong..

How the fuck is a fan supposed to do anything when it's smooshed against the carpet?

>>54553086
You put your computer on the carpet?
That's terrible. Tons of dust.

Temperatures were fine, 50C constantly under heavy stress, so I don't know why I'm lagging.

Exhaust fans aren't removing hot air fast enough that the GPU is forced to reuse hot air to cold down.

Removing heat from a case is easier than trying to cool it down with tons of fans.

>>54553180
50C and still lagging?

Odd. Try reinstalling your drivers, see if that works.

That case has big ass feet that holds it above the floor.
