HD 4870, Need assistance

Hello,

I just got my new Radeon HD 4870, actually I switched from Nvidia to Ati after great reviews about ATI 4800 series, I like the catalyst control centre but I need assistance in one area.

I was playing around with CCC by changing fan speeds but what I want is to make multiple speed profiles say FAN40, FAN50 and FAN60 (with numbers indicating their duty cycles) and I want to activate profile automatically on a particular temperature threshold say on 60+ deg centigrade I want FAN60 to be selected, for below 60c I want FAN50 to be selected and so on... but I can't find a way to activate profiles on temperature thresholds :? Is there any way to achieve this ? please guide.

Thanks in advance.
