Default 5850 running too hot?

Hello, my xfx 5850 is running hotter than I had expected at idle (~50C), and jumps to around 75C on load. Room at around 25C

From reviews, it seems it is a bit hotter than what most 5850s are running at, and I was thinking of reapplying the TIM on the card.

Is this a difficult process? Would I see much of an improvement? I want to keep my fan as low as possible, and don't want it getting too loud. I don't really want to spend another $50+ on 3rd party cooling.

Now, in order to do this, I know I just have to unscrew all the screws in the back, clean stock TIM, reapply, rescrew. The one thing I was concerned about is the thermal tapes. Would they need to be replaced once they come off? Any video/picture guide I can follow to make sure it goes okay?

Thanks!

75C at load isn't that much. I personally wouldn't even bother.

For a 5850 it's a little above average. Is it overvolted/oc'd at all? Fan speed? Whats the air circulation like around it. Changing the TIM might help a little bit but addressing the other issues first may yield better results.

I'd say turn up the fan speed and see how that works, and then if you can mount a fan inside the case to shoot cool air on the back of the pcb/in the intake. Do what you can, but replacing the TIM will l probably not do much.

yeah, i'm a little worried because it's on an open bench right now, with fan at 35%+ on idle. still around 55/75+ idle/load.

it is all stock settings, it is the xfx 5850 black edition.

i will try re-doing the TIM.

With XFX you will be safe redoing the TIM since it will be covered by warranty.

In a Case with "proper / efficient" Air Flow would you not get improved Temps over an "Open Bench" ? I would think so...
