I have the Asus 4850 and it came with a auto fan control. This way when you play games, it'll crank up and stay quite when just browsing in 2D.

Does anyone know what the defualt min and max speeds are for the radeon 4870?
I was considering the softmod but I want to be sure I don't fix the speed too low. Also what is a good temp monitoring software for these cards?
According to CCC, 500/810 and 790/1100 - the card is totally stable maxed in CCC. Using AMD's GPU Clock Tool, you can set it to whatever you want. As for temp monitoring, get the latest version of GPU-Z.

1. Make sure you have Overdrive enabled and MAKE sure your clock and memory settings are correct!!!!
2. Make a New Profile Name it something like fan. I made numerous profiles with different fan speeds so I started off by naming my first one (45 fan). This one is for the fan speed of 45%. Click save profile the activate&close button.
3. Now open up windows explorer and make sure you have the "show hidden files" enabled.
4. Now follow this and find this folder C:\Users\David\AppData\Local\ATI\ACE\45fan. XML. (the david will be your user name instead of my user name)
5. Now find the file 45 fan.xml
6. Right click and then edit.
7. For only one 4850 card (non crossfire):
<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Automatic" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="0" />
The Bold ones above. Change the Automatic to "Manual" and change the 0 to 45"
Then save the file.
Now go back to the CCC and go to profiles and activate the profile 45 Fan.

Works perfectly for me. 50% fan speed gives perfect temps, all below 60ºC when overclocking.

Anyone have the MSI R4850 with the copper heatpipe cooler? Looks somewhat similar to the Arctic Cooling solutions only it's shipped that way (so you don't have to do any mods yourself.) Just wondering how it compares heat/noise wise with the other dual slot cooling solutions out there.
I'm kind of waiting to see when the Arctic Cooling Twin Turbo that is specifically designed for the next gen cards comes out, but if it's running for the 39 bucks they have listed, the MSI solution might be cheaper. Of course the Twin Turbo might allow for bigger overclocks. Decisions, decisions...
