    Ok, i've dumped that idea because i'm going to modify my VF900 with 92mm Akasa fan.

    However i did try placing a 80mm fan to intake air through PCI slots in the back. Guess what, the card temperature remained at steady 88°C during RHDRIBL looping. And all i did was to place low RPM 80mm fan to intake the air so its air stream was almost directly feed into the graphic card fan.

    The 4850s do not have a heat "problem". They have low fan speeds. I appreciate this because I HATE loud computers.

    ATI seems to have chosen to run the stock fans at low speeds. Apparently to limit overclocking and competing with the 4870s. Since the 4870s have 2slot coolers this will solve the only "problem" I see, by exhausting the heat out of your case.

    Of course you'll have to spend MUCH more money for the same GPU. So for the price of 1 4870 you could XFire 2 4850's. I think I'll save the $150 and leave my case open!:)

    I had the exact same problem but then used Windows "Search", tick also Hidden and system folders and found it that way, I had at least four of the ACE folders and just opened each till I found the profile.

    Your a Champion Brettware I adjusted mine to 35% with no noticeable audible difference and went from 68C to 55C idle, going to refresh the Thermal Paste with Artic Silver 5 and see if this helps as well.

    NO! :) You're supposed to tell me how to exhaust the heat!

    Seriously tho, can anybody post the default profiles.xml file? I STUPIDLY modified mine without making a backup and now it is loading that as default and I can't make the edits stick. It keeps creating a new profiles.xml file with my mods as default.

    I'll be installing Zalman VF-950 on HD4850 after all! Can't wait.
    I've also ordered 16 copper BGA heatsinks to cool down the memory. I really want to have 700/2400 clocks on my HD4850 mwahahaha

    It has been said elsewhere and it dawned on me as well you can make 4-5 different profiles, e.g. Fan 35%, Fan 40%, Fan 50%, Fan 60%. While you are in the Profile Manager click on the Activation tab and tick "Desktop Short Cut" then save Fan 35%. Now you will have a desktop icon for each profile you have made so you can change the fan speed at will depending on activity (low for web surfing, higher for gaming). I have made 4 and have saved them into a desktop folder called Fan Speeds.

    To give this a good test I used "FurRenderingBenchmark" to really crank the GPU and found I could change speeds mid-test:

    http://www.techpowerup.com/downloads/715/Open_GL_FurRenderingBenchmark.html

    By removing my heatsink and refreshing with Arctic Silver 5 I also saved another 2-3C in idle.

    So I have a profile of 40% (can hardly hear it) and went from 69C to 55C, refreshed the TIM and went from 55C to 51-52C. Well TIM is still bedding in so 50C at the moment but it is a cool night.

    Nice, just 50% on the fan dropped my GPU temp by ~20*C! This is a great solution until there is a new RivaTuner! GPU-Z says my fan is going at 4453 RPM, LOL!

    My Sapphire 4850 just arrived this evening.

    I want to thank Bretware for his "hack".

    I have mine set to 35% which is barely audible. If I need to increase it, I will, obviously, but for now it seems to be doing the trick.

    Does anyone know how to get the profile to apply to both GPU's? I have a crossfire setup.

    There are two sets of those entries! Fill them both in with your desired percentage...

    Repsonding to an earlier post, here's is what I do for heat removal from the case,

    http://i277.photobucket.com/albums/kk59/bretware7/IMG_5532.jpg

    There is also a fan mounted to the side cover with a duct pulling from above the the video exhaust ports.

    This helps insure the cool entry air into all heat sinks.

    This is an old pitcure, I'm now running a MSI K9A2, and a Rosewill Z-3 fan wich required a new duct system
