I know interesting title right? lol. Anyway, for some crazy reason, it annoys me that me 2011 27 inch iMac never gets hot and make the fan speed up...I started folding at home before i went to sleep, came back the next morning, still working, 100% CPU usage, CPU temp, 59C...fan...default 949rpm...in windows however, prime95 for 5 min gets all four cores up to 63C and idk about the fans because idk any fan monitor for windows...and using CPU-Z i can see the whole time its turbo boosting between 3.1ghz and 3.7ghz...Maybe Windows is a little more aggressive with turbo boost then OSX? I feel like in OSX that my processor isn't working as hard as it can because of these low temps...i idle around 28C by the way...I am on a base 27" iMac 2.7ghz quad i5 Radeon 6770M 512gb 1tb hard drive yadda yadda...anyone have any ideas on why this is happening or interesting info? Also you guys with 27" iMacs, do you notice the same thing i do?
