Hmmm, are you sure? I can't recall ever doing that with any of my video cards. Well, give it a try and see what happens. I use the CoolBits only for the overclocking feature though.
Here's something I found on that Coolbits website you linked:
"Q. I dont see the temperature settings, is this due to my card?
A. The temp settings panel is only available with cards equipped with thermal sensors. Some cards that I know of have temp sensors are 5700 Ultra, 5800 Ultra, 5900 non-Ultra and Ultra, and 5950 ultra. But really it all comes down to the manufacturer. I have seen some 5700 and 5900 without temp sensor, but mainly the cheaper XT/LX/SE versions."
That's what I said in the first post, but I don't know if the 6200 have sensors or not.
