What's your experience with the heat of a 4850?

I can't believe how good this card is for it's price. However there is one thing that concerns me and that's the temperature of it.

Looking at benches and reviews I've come to the conclusion that'll be a very hot card inside my already hot Q9300 setup.

This is for anyone who owns a 4850. Does your card overheat, how is it in games? Is it just natural for it to run at such high temperatures? How future proof is it in terms of hardware failure?

I'm split between the 4850 with an amazing price of £130, or a 9800GTX for £180.
 
I'd give it a while for all we know nvidia will undercut the 4850 with the 9800gtx+.
 
Well overclocked versions of the hd4850 will eventually come out with better coolers.

With ambient temps of 27C I get idle temp of 74C, atitool artifact scanner 89C, furmark 92C. The stock fan ramps up and is actuallly very noisy. Im probably gonna put the s1 on it after a proper overclocking tool comes out.

As for the choice between the hd4850 and 9800gtx at those prices, its a no brainer.

1 thing to keep in mind is that the VRMs need to be covered. The S1 will only come with 8 ramsinks I believe...so you will have to sacrifice some ram cooling for the VRMs unless you want to buy more chips...as i have done :)

Here's my little collection of sinks and thermal tape all ready :D

I have also seen someone hacksaw the little heatsink plate off the stock cooler......but I wouldn't really want to do that.

u can roast a chicken on it. rofl joking i dont have it but if you take cooler of re apply thermals paste the temperatures should go down or get custom cooler

yes I think it does, but the 4850 has 2 groups of chips that need to be cooled.

here's a pic of my naked 4850 showing the hot bits that need heatsinks :)

I would not worry too much about the grey (not totally sure what they are) guys, they did not have sinks on the 3870's! just get some cooling on the little FET's

Problem is that a 90C+ the fan ramps up to 50% and is very loud.

Yes, The cooler is more than capable of running quietly and keeping the card at 80c full load and under 50c desktop, but again ATI has ballsed up the release Bios exactly as they did with the first 3000 series
Fantastic card with a best in class cooler!....they might aswell have left the fan totally disconnected :rolleyes:

But they ARE cooled on the 4850 and they do get VERY hot...so I would think it's a good idea to cool them.

and C64, yes
 
so looks like 4 standard ram sinks for the grey and ideally something like these for the black

It's a pain actually because you are better off buying another accelero it will be cheaper than buying 2 sets of sinks which is plain daft the sinks shouldn't cost as much as they do.
Let me know who does the arctic silver on the ram and other areas with a tiny blob of super glue in 2 corner of each surface to hold them down.
I hear people are using the exsisting white gunky strange cloth like material that sits already on the ram to stick the sinks on.

people have been using a hacksaw to chop off the end of the cooler actually.....depends if you want to do that to your card or not though....
