Hi guys, I have few questions. I run a 27 iMac on 10.11.1. It has a 2,7 GHz Intel Core i5. I have a question about temperatures. I am playing games on my iMac a lot. Sometimes when I play Runescape or HotS, the temperatures are bit high and fans are bit loud. It takes some time to cool system down. I know its a old iMac but I love it. I have never cleaned him. Should I? and if how so? The tempetures are: HD: 56 C CPU: 50 C Ambient 34 C GPU: 70 - 72 C when gaming after its about 60 C Mem Controller: 56 C Optical Drive: 52 C Power supply 2: 69 C And the CPU fans are usually about 2000 - 3200 rpm (when runescaping) The others are 900-1100 rpm Can I do something? Thanks for the answer.
