GPU usage question

[Foxhoundn]

Hello,

 

Recently, thanks to the LTT community, I awesomely updated my rig. I have AMD 8320 and GPU GTX660.

 

The thing is, today I have bought 2 additional fans for my case, 80mm to back to keep the air flow and 120mm to the side. Both of the fans are PWM and since that I have been kinda playing around with SpeedFan etc.

 

I have no idea if it is just a coincidence but what am I seeing is that when I am in a game, say World of Warcraft I see my FPS to drop to 20 even thought MSI afterburner shows that the GPU usage is only at 40%

Is it possible that I messed something up when I played with the chassis fans? All I did was to enable the CPU Q-Fan in BIOS (later in ASUS AI SUITE). To me it seems quiet unordinary that the GPu usage is only at 40% but the FPS drop like that Same thing in Borderlands 2, the GPU usage is at around 70% but FPS keep dropping and it starts to frame-lag.

 

Any help or guidance is more than appreciated! I feel lost and that I screwed something

 

PS: The GPU temperature doesnt really go above 50+-, maybe something blocking it? dunno

 

Thank you

Are you using some gpu overclocking utility like MSI afterburner? if so go check that artificial limits weren't accidentally activated on it?

That's my first thought anyway

Hello Sea,

 

No I dont think so, here is a screen of the afterburner along with other utilities:

 

 

it kind of bothers me, why dont I have more FPS when obviously the GPU could give out more

Thanks

Update,

 

I have been playing Borderlands 2 now and the GPu usage was at 95-100% for some time but then dropped to 70% etc and got back up

 

 

My question is, should the power % be sketchy like that? Because for the AMD 8320 and GTX 660 I have only 500W psu.

 

Im kinda worried what the problem could be

 

Thanks for any help

Please guys, any idea? Could it be the PSU 500W is not enough?
