4870 idling @ ~95c

My graphics card has been running at ~95c when it's at idle (with fan speeds @ 60%). This has been happening for a few month now; however, all I did was get Rivatuner and underclock my graphics card to the lowest possible (375core/225memory). This allowed for very acceptable temps (around 60c-70c idle with fan speed @ 60%).

Lately, I've been starting to game and I put my clock speeds back to normal (750core/900memory), and again, even at idle my temps. are closing in on 100c.

I have to blast the fan speed (with ATI overdrive) to 100% including a room fan blaring into my open case.

Is my card just defective?

I have opened up the case and cleaned it with a lot of dust being removed. I still have to try replacing the thermal paste. Would this
completely solve the problem?

Thanks for any insight!

That is a super high idle, Paste could never hurt.

How is your airflow?
 
did you clear away dust from inside the GPU HSF?

Do your web browers still have GPU acceleration enabled?
 
Haha paste. Its dust clogging up the fins. Had it happen to my old 4850 when I could start hearing the fan whine while browsing the internet.
 
wow thanks for the quick replies fellaz, appreciate it!

I'm afraid to say that the top fan on my case is NOT working at all. Other than that, I have the side panel open so I can have my room fan cooling it.

My browser did have GPU enabled but I shut off all programs before I game. I got the red tube for the spray and I just stuck it in the graphics card and cleaned it that way. I also did the same with the actual fan of the graphics card.
 
My alienware laptop used to idle very high on both the cpu and gpu, the paste dried out and made poor contact upon replacement temps where far lower.

He clearly state he cleaned the dust out of it.
 
Well if he is kind enough to post up an actual picture of the video card we can assess the condition much better. :)
 
You should try to remove the heatsink,clean the old thermal paste then applying new paste.
 
yea my guess would be improper contact between gpu and hsf.
