well i need two, one for me and one for my sisters kids pc.
story , my one is too loud to keep cool and my sisters kids one, well when he gones into one game it crahs's and says display driver issue, the ati software sayed the fan is on full but the temp still goes up to 60 idle plus ajusting the fan speed does nothing.
so what one to get, i got my eye on these two
gfxchilla
or
AC twinturbo
EDIT : forgot to put both cards are 4850 with 512 ram, one is made by his (mine) the other is asus (kids)
Do both cards have the stock single slot cooler?
Have you tried reinstalig drivers etc
Also the ACTT is a poor cooler i my expoerace get thisinstead.
But these cards can operate up to 100c fine so the card itself may just be fubared
I have the Akasa Vortexx Neo that the previous poster mentioned. The stock cooler will be quieter when you are not gaming if your HD4850 has the reference cooler. However when you are gaming the Akasa cooler will be much less noisier. The reason is that the fan on the Akasa cooler has a fixed speed. The only way to vary it would be to use a fan controller.
yep, reinstalled the drivers and both have the single slot coolers, mite have to get them cards, looks like the ones i put on my 9800pro and 9600pro , cheeper as well :)Quote:

same on the 4850Quote:

I'm not sure about the Vortexx. It seemed good for cards such as the 8800gt, but the VRM's and memory on the 4850 run a bit too hot for me to trust it :/
One trick I remember with the 4850 stock cooler, is you can keep the VRM heatsink from the stock cooler by physically cutting it off.
Which is handy as VRM coolers are not that easy to find.
The Vortex Neo is rated very highly as a cooler for the 4850 and is more like the 4870 cooler (or the old GeCube 3870/3850 cooler which was probably the single best prefitted aftermarket cooler for them, why GeCube didn't use them or a veraition of them on there 4850/4870 I'll never understand)
For low noise cooling I seem to remember that the Scythe Musashi is very highly rated, although not that cheap.

Also the thermalright T-rad2 (you'll want to buy fans to go with it) again not cheap
