Remove the stock cooler and use a Zalman VF1000.

These cards were apparently supposed to run quite hot. Although, 90c is still in the "safe" range. I would try what redsunx said, and remove the shroud and place a fan over the heatsink and see if that helps.

How is the fan noise at 40-50% on the 4850 by the way?

I've been looking around and it seems that most of the reviews mention no fan adjustment and high temps.

I think its just a cruddy reference cooler. If you look into it most ATI cards are safe up to over 115c ! . And another thing to consider is that you do have a lifetime warrenty with VisionTek so if worse comes to worse replace it OR if you bought it @ BB exchange it in 14 days. I for one am waiting for reports of which aftermarket cooler will fit the card and will change it out along with some as5 or ceramique.


Of topic'ish: Has anyone noticed when you boot you PC that the fan Spins up to what i assume is 100% and 2 small leds on the back of the card light up freaks me out 0,<

You could just put another fan on it. This DuOrb keeps my overclocked (860Mhz) 3870 below 55C all the time. I'm very happy. Still having fan control problems with my other card and fighting with Sapphire over getting a BIOS to fix it. It kills your warranty to change the fan, but if heat is going to be the cause of a warranty issue, then you're better off just changing it and never having to RMA the card. I did have to RMA one of my 3870s (which is why you only see one graphics card in my avatar), it was the one without the DuOrb.

Try the Arctic Cooling Accelero S1 Version 2. I've heard that the 3870/3850 coolers work with the 4850
