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

what do you mean ? and why does the default solution to that end of the card have to come off?

Note in the top half where i have outlined there was a bit like i have suggested which has been hack sawed away?
why is that necessary ?

Bottom pic This default heatsink why is it required to either remove it or hacksaw it ? is it too high ? it looks low profile to me ?

The heatsink is all 1 copper piece..if you want to change to an aftermarket cooler the whole thing needs to come off, meaning you won't have the little finned cooler at the end either.

So, as pictured, some people cut it into 2 pieces so they can remove the heatsink/fan assembly but leave the VRM cooling intact.
 
I no longer have a heat problem, solution: VF900

Originally bought for my X1900XT but after it didn't fit properly it was just boxed up and put away. Found it the other day and tried it out, fit perfectly and temps are great 43-46oc idle, 70 load. With the stock cooler it was unstable at 650/1050, with the VF900 on it, it's happily sat through 4 hours of gaming at 700/1100. Extremely pleased! :D

Edit: Those temps are with the VF900 at lowest setting, at highest they go down to 40oc idle, 65oc load.

Mines currently:

Idle: 81c
Load: 90c

Those results are on the stock cooler, probably hotter than some as my ambient room temperature is normally 30c - 35c or higher. I'm waiting for my Thermaltake DuOrb to arrive so I can use that.

Chop that sucker off and bang goes your warranty I recommend people don't do this and get aftermarket sinks instead.

Yup, exactly.

I got that picture from XS though and no one there gives a rats ass about warranties lol
 
well When you want to sell on which you will certainly do
has it got any warranty left ? no because I sliced it in two with bread knife

Erm lol? Replacing the stock cooler with any aftermarket cooler also voids your warranty as they can't guarantee that it will work sufficently.

I certainly wouldn't use a bread knife for cutting off the copper heatsink.

Your other half/mother will not be impressed.:p

Yes but they don't know that you did when you put the default heatsink back on.
 
hey i'm a thinking... if a after market cooler is say.. £20.. why not go for the 1gb asus version which seems to have a decent cooler on, does it not?

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

Not in full agreement there, I just made a custom cooler for a HD3850, ok much less load on the power circuit but even the fets did not get warm !

It is hard to fix anything to them, You would be better making a custom sink and fixing through the screw holes at each end
I think the Grey blocks may be heavy resistors/inductors and up till now have not been cooled....sure for what Your after cool everything ;)

Well you may be right but I have spare heatsinks so I might as well put them on...and on my Powercolor 3850 they got burning hot, they did not have sinks on them from the factory but I put some on and it seemed to help stability when the card was heavily clocked.
