Is there anyone that uses fan app that fixes old imac that seem to overheat easily. my imac seems to like to freeze every day within 30 minutes to 1 hr due to internet usage such as youtube. I used this old imac for mainly adobe suite and other video software, but it tends to crash easily. So is there anyone that can recommend me a good fan app. according to istat pro app the GPU Diode tends overheat around 66% to 70%. What I want to do stable the cooling of the machine. I have a late 2006 imac 2.16 ghz intel core 2 duo. 1 gb memory. colored white plastic. I know it tends to overheat mostly during the summer time.
