Good Afternoon. After installation third Operation System my Imac(27) heating quikly and better.
I had MacOs and Win7 32bit(installed in Shop). It was ok.
But 32 bit OS didnt work with 8Gb RAM. Therethore i installed Win7 64 bit.
Now i Have MacOs, Win7 32bit, Win7 64 bit.
Before installation WIn7 64bit, in Win7 32bit my Imac was working in common mode(Internet\Video) without propeller noise. But now, i have noise after 10-15 minutes Video or Browser using.
In Win7 64bit i had more propeller noise and after 10-15 minutes play computer game, i have lags and troubles with performance!! My propeller's are spinning with maximal velocity(after 10-15 minutes). Therethore i cant play games\watch Video in my Win7 64 bit. I think that i must be install someone drivers?? I have BootCamp 4.0 under my Win7 64 bit.
In Win7 32 bit, i dont have problems with perfomance, but noise is really stronger than was early.
Please, Help me!
