My white Santa Rosa 2.2ghz late 2007 macbook over the last few months has been getting worse and worse with its fan noise. Currently, I have have this tab and another on the BBC News homepage (flash blocked) open in firefox writing this up, and according to istat my fans are running at around the 6100rpm mark with my CPU temp around 65 c. Have tried and SMC reset, and hasnt fixed it. Not really sure what else to do? Checked the activity monitor and nothing else seems to be using more than 7-10% of CPU. Not really sure what else to do?! Please help!
