4870x2 Cleaning!

[Colonel Mitch]

After my filckering fail, which has only happened since installing my soundcard, im hoping was a coincidence. I have noticed that with crossfire enabled or disabled on any full screen game the fan goes to 100%, temp goes to around 107*C and then every now and again flickering occurs - but not right away, and becomes more frequent as your play.

Hoping this may be to do with card overheating.

So..... dismantled the card in its few stages to find a very lange clump of dust almost completely blocking the first heatsync...





Compared to the second heatsync down the card, with very little...




Cleaned them both off and now its idling at around 58*C comapred to 80*C which is good.... will have to hope for the best and test in games now

And for any of you interested - this is waht a Powercolor 4870x2 looks like with no casing....

[Colonel Mitch]

LOL @ the difference.....

Now runnign Modern Warfare 2 with everything in Control Centre on full (32x Wide Tent Anti ailiasing for example :P)
and now it hits 87* at 40% fan speed....

Its insanely quiet when you've been running on 100% speed for months...

havent given it a long playtest yet but no glitching in first game

Glad to hear those high temps didn't damage it

my x1900xtx used to go to 115*C and that was jsut barley on the redline in control centre :P

the 4870x2 was only jsut in the red at teh temps it was gettign

Grats at fixing the problem

(Although lol at the knex case still)

Good job Mitch, not sure why I never though that this could be the problem . What kind of thermal paste did you use to seal the heatsinks back down?

I used the thermal material that was already on the chip/cooler/heatsyncs.

In other words - none.

hehe, at school the processors in our 'home-made' server computers (for my class), have been sitting there for so long, the thermal paste has hardened and stuck the processor and heatsink together, I must say it is quite lol.

Thats because its thermal cement then, and designed to do that :P

80c idle is toasty for any card

[Colonel Mitch]

80c idle is toasty for any card

not for my 1800 or 1900 it wasnt, and this doesnt redline till 100 n summit

[Target]

Its always dust, you just think it must be a gay technical fault or something just doesnt want to work

[ez64]

If 80c was the idle on full load it would have been toasty and wouldn't have done it any good.

[Colonel Mitch]

oh yeah 80 idle is a tad warm lol ^^
