Radeon HD 4870 TEMP

[sethwillkaye]

My graphics cards temp is around 78 to 79 C idle and any thing up to 99 C under load, im having problems with my computer turning its self off after like 30 to 60 mins of playing a game this the problem my graphics card overheating?

most likely yes, it is a heating problem.

It's runnng a little hot .
First, you'll want to get a can of 'compressed air'-it's widely avalable through computer and electronic stores.
Next, remove the card, take it outside, then use the air can to blow the dust/fur out of the cooler. Exactly how to do this depends on the cooler but you should blow backwards, into the exhaust, so the cleaning gas stream blasts towards, rather than through the fan. Usually some detritus sticks to the fan blades, use a cotton bud or old toothbrush to remove it followed by a short squirt of the air can to finish off.
Check the CPU cooler as well, if it's clogged you should give that a good blast as well, overheating of either will cause you problem.
BTW, do n't use the 'air' for too long, it can produce a stong static electric charge, which WILL fry the component/s it is directed against-remember, short, controlled bursts, Ripley

all the fans and components have already been cleaned properly

Idle temps for that card should be around 45-55c and during gaming 75-85c , depending on room temperature

how is your fan speed set up Auto? or manual? I set it once on manual 20% and forgot that caused overheating

 

[sethwillkaye]

the cards fan speed is set at 100%, playing sniper elite v2 it hit 118 C so im guess the problem is the graphics card

What are your other temps- CPU temp?

You either have old dried up heat goo/pad, or terrible ventilation in your case.

I know it's a bit old but here's a dude who managed to take his thermal pad and rework it using a dryer.

Personally, I'd just buy some more..

 

[sethwillkaye]

the goo/pad was dried up so i would need to buy more on the fan underneath where it touches the graphics card??

 

[sethwillkaye]

cpu temps are around 50 C to 60 C

 

[sethwillkaye]

and it was goo not a pad BTW

 

[wavetrex]

Generic 4870 idles at 80 degrees, always, and attempts to maintain load temperature below 90. It's factory default... If it reaches 99 then it has a dust problem.
I know this for a fact because I still use one.

However, you can manually reduce temperatures both in idle or load using for example MSI Afterburner which can create a custom fan profile ( however the card will become louder )

sethwillkaye yip, that's defo your prob. Simply pop down to your local store and ask for some Arctic silver heat goo!
