Very hot gfx card - Saxperience

davidandrews5343 · 23rd November 2009, 17:58

Before i start please only post if u know what you are talking about. Opened my pc case up today to find way too much heat, turns out to be my nvidia 8800, after runing ntunes its reporting that my card is at 97 degress!!!, the pc had just been idleing, the fan was working on the card and air flow wasnt blocked, Is it possiable for the card to run stable as this temp or do i have a faulty temp sensor, i have underclocked the card down to its lowest frequency and the temp has dropped to 80, tho the card isnt much use at these speeds.

How many other fan have you got and where are they? And what sort of case have you got?

GPUs run a fair bit hotter than CPUs... that sort of temperature under load isn't uncommon. You'll definitely notice in-game if it's reaching stupid temperatures - poor frame rate, maybe even artifacts/ banding.

I wouldn't worry about it though, just make sure the fans are free of dust.

Case is thermaltake swing, this temp is not under load, just idleing, got fan on gpu and 2 case fans, 1 for cooling hard drives, 1 large for getting air into the case

I assume by the light youve got a cut out? Best thing to do is to get a good air flow like air in front, hot air out the back with most holes covered up around the sides and what not.

And by the looks of it give it a good ol'clear out. Like a very good one all dust gone and clean the fans themselves too.

Probably won't make much difference, but I'd turn that fan at the back round. Make sure the one at the front is blowing into the case too. Then get yourself a can of compressed air and give it all a good clean.

Youd be surprised how much of a difference it can make

cut out? i have a perspex side pannel, tho its faceing the wall so light isnt really seen, ill try reverseing the fan on the back so its blowing air out

Simple, clean out the dust from the case fan mate, and that orange fan is the wrong way around on the case.

The fans on the front of the case intake air, fans on the back exaust air, turning the fan around WILL make a noticable difference.

Check what ntune is reporting the fan doing, my friends ntune bugged out and turned his fan to 10% all the time.

Thought as much, try taking the card out and giving it a blow of air and clean the fan with some cotton buds.

I had a a similar problem with my 8800 Alpha Dog, the standard fan spun up, reported the card was overheating and cut it out to prevent damage, but I simply put an after market cooler on it and its fine and stable at 35degress now. By the looks of it you have the same cooler on it, try taking it off and re-assembling it ensuring you got rid of all dust to avoid dirty connections.

Doing so would break the warranty.
I would call up/email the manufacturer if all said above doesnt help thing and see about rma'ing the card.
That way it will get fixed instead of taking it apart/fitting an aftermarker cooler....the problem persists and you have just broke the warranty.

Switch the rear fan around, clean all of your components as they're disgustingly filthy and see how it goes.

Do you keep the side of the case on? Most people will take the side off a machine if it's running hot but that actually completely disrupts the air flow and will just leave stagnant warm air around all of your components.

Clean, re-seat all components, switch rear fan, keep side on and see how it goes.

Thought it already had an aftermarket cooler as it looked like a blueish colour, but that I have just realised is infact the neon reflecting of the matt black surface for the standard cooler.

Damn, didnt realise that post came in, meant to quote the one above lol.
