Is smcFanControl still the best to use to increase rpm's on fans for macs? Or is there anything new out? This iMac get EXTREMELY HOT on the top left corner it can burn your hand how bad it is. The atual temps are within limits with istat but that excessive heat on the back left top corner is concerning me. If i keep my hand on it for more then 5 seconds it will actually burn my hand. I think that applecare is a must on imacs. Also the HD idling at 50C it's a little to high. I am seriously contemplating if I should just return the iMac and get the 27 inc cinema display instead for my Mac Pro. I bought the iMac for web browsing , watching movies onlien etc.. and this use should not get the machine this hot. Sure my CPU idles at around 45C wich is acceptable I guess , although on my PC anything that idles at over 38C is unacceptable to me, and I understand that the iMac is a unique design and heat is to be expected but wow. And it's winter time here I can only immagine in the summer time if I keep my ac off this thing will melt on me lol. I see a lot of complaints on the iMac screen etc... but I think that this is the most serious issue with this machine atm. Anithyng that get so hot to actually burn your hand it's pretty serious.
