Very hot gfx card

[davidandrews5343]

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.

[Toms112]

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

[Liam_]

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.

[davidandrews5343]

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

[kennysevenfold]

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.

Ill get that reversed

fan is at 100%

What version of the 8800 is it?

gts/gtx by the looks of it?

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.

yeh ill reapply thermal compound, just loaded up nfs shift, game ran fine tho the card went up to 102

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.

[gj89]

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

[Penn]

Just a thought, what heat does that silly blue neon tube kick out? It's directly below your gfx card.

[Liam_]

Unless the card is giving very poor in-game performance then it's nothing to worry about imo. If temperatures go dangerously high the card will cut power to prevent damage.

True, but it should not be running that hot.

I've got an ATi 4870 (non vapourchill), it's sitting at 70 degrees idle and ATi's have always been known to run quite a bit warmer than nvidia cards.

[Liam_]

NVIDIA say their GPUs are rated for operating temperatures past 120 degrees. It won't even be breaking a sweat at 80 - 90. ;)

As said, it maybe is a little toasty for an idle temperature. I'm sure if he swaps the direction of that fan and gives everything a good clean out with compressed air it should improve.

[davidandrews5343]

a clean of the gfx cards heatsink and fan, plus fresh thermal compound has dropped the idel temp to 64 degrees, mental amount of screws on that bad boy to get it apart

I have not read the hole thread but just the other day some one asked me to look at there PC that was having problems. It turned out it was a GFX card that took up two slots like yours does. The only thing was whoever built the thing forgot to take the second blanking plate off the back of the case and so the GFXs cads vent was blocked at the back and over heating. So its worth a look as it may be the same for yours.

The other thing is try running the case open and see if it still over heats. I have a couple of ATI 4800 in my case and it over heated unless I took the side off. I fixed the problem by cutting a big hole in the lower front of my case and fitted a big (120mm I think) case fan blowing air in.

vent isnt blocked, some people say case off, others case on lol, i have side on

[AXracing]

A well designed case with the correct hardware inside for its design can cool better than just sitting in open air. But lets face it PCs are a botch most of the time. Its worth a try opening it up and if it does run cooler open you know you have a air flow problem in your case.

Edit, just had a look at your photo what way is your extra case fan turning? It just looks like its sucking air in not out. If it is you will want to duct cold air two it as at the moment it will just b sucking in hot air from the back of your PC. That or spin it round and have it sucking.

[kennysevenfold]

Dont realy want to leave the case open all the time, you want it to be cool with the case closed as it was designed to be.!

How is it now?

[miken2k8]

my 3650 runs at 60c at idle if it does overheat the power supply will most likely cut out anyway

[Viper]

my 8800GTX doesnt give out that much heat when im playing a game with maxed out graphics!

Ideling now, after being turned on for well over an hour the GFX temp is 51 deg. C at the core!

Must have terrible air flow, or fan not working properly.

My PC is kept in the PC space in a desk unit, so the airflow to the unit is fuck all. just goes by the fans (Antec 900)

[bagnaj97]

As well as reversing that rear fan and cleaning everything with compressed air you could try replacing the CPU heatsink with one with an upright fan (I'm pretty sure that's an Arctic Cooling Alpine 64 you have now, try replacing it with an Arctic Cooling Freezer64 Pro). That will help push the CPU heat towards the rear exhaust fan and lower the overall temperature in your case.

You could also try replacing the thermal compound on the GPU heatsink. If you do this remember that just wiping the old stuff off doesn't work, you need to use TIM clean, or at least rubbing alcohol, and too much thermal paste is often worse than too little.

Whilst your card is running too hot it's not (yet) affecting performance, nvidia cards throttle at 120 degrees IIRC. It will shorten its lifespan, but will still almost definitely become obsolete before failing. My 8800gt sometimes gets as high as 96 degrees, but that's because it's in a rather small case...

8800 series are old. i bought it the day it came out. With in a month it was out dated.

iirc, most top end range gfx cards are around 1.5GhZ :O

Are you running a ASUS A8N-SLI Deluxe Mobo? With a 2.4 Amd Athlon CPU?

[MarkyG]

If you can, I would highly suggest getting the card RMA'd as said earlier.

I owned an 8800GTX XXX Alhpa Dog Edition and never had any heating problems under load or idling. Pushed it to the limit and the hottest it got was 75. I had and still have the same 4 system fans (x1 bottom behind my PSU, x2 at the top of the case, 1x at the back all 120mm, although i spent about £12 a fan, I've never been unhappy with them, barely any noise from them! Have just upgraded the mobo, cpu, RAM, GFX Card and HDD's.

I get more noise from the Zalman cooler I have on the CPU!! But the fans still live on.

A good clean is a big yes in my books. Dust is a git if it builds up, not only storing some of the heat during running the system, but just causing a general heat issue altogether. if it comes to it, strip the system down and get everything out. Long-arsed way of doing it but it does it good in the long run. I guarantee you will find more clumps of dust behind the motherboard than you expect!

[MarkyG]

Keep the side on, never take it off unless you want to do damage to your components over a long period of time with a high amount of running hours.

As said earlier it will dirsupt the airflow and any heat will jsut hover around each component.

[bagnaj97]

Agreed, but if you do this use a can of compressed air. DO NOT HOOVER! When using a hoover static electricity builds up on the nozzle and this easily damages computer components. Components come in antistatic bags for a reason...

Like pretty much all pc hardware......
