Graphics card with thermal paste

[OBielegend]

My crossfire hd 7870's when gaming for a few hours start to get really hot about 60C-70C.

 

A friend said that for a small improvement I should take off the heat sink and reapply new thermal paste and that will help a bit with the heat.

 

I was wondering if that is true or if its a waste of time and thermal paste.

 

The thermal paste I have is artic silver 5.

 

Thank you

if the 7870 is quite old then changing the thermal paste could improve temps but if the card is new the artic silver won't be any better than the stuff the board partner used.

Just to clearify this; that's not hot. at all.

 

New paste will help, but not a lot ;)

That is true, but the temps you have are very normal with graphics cards. I don't know if it's the same with 7xxx cards, but a guy with his 6950 replaced the compound on it with ic diamond and while stress testing his temps went down 15c.

If you have had the card and same thermal paste for a couple of years it will help improve your temperatures by a couple of degrees if you apply new thermal paste. also if you do decide to take it aprt to do so I would also recommend to get compressed air and remove all the dost from the fan and cooler. this should help lower the temperatures a good amount.

60-70c is normal under load, especially if they are in crossfire it could even be considered good.

Yes, 60-70*C is excellent in Crossfire under load. Start worrying if it hits 90-95*C

You can replace the thermal paste if you want but considering you're getting great temps as it is now you'll only make things worse by replacing it.

I have had one card for a year but the other only about 2 weeks.

This is what I thought thank you
