Our MacBook Pro is back from the Apple repair, with their usual response – "heat is within apple spec". But after updating MBP with this SMC firmware I feel it’s slightly cooler than before and fans are kicking more often. I used CoreDuo Temp to measure the CPU temperature; before the update max. temperature during my normal use was 72 °C but after the update 66 °C is the max. I’ve seen. (Normal usage means; turning on for 2 to 3 hrs and using few daily applications like browser, email client, etc..)
With 100% CPU usage temp. goes as high as 78 °C
I found a web site intelmactemp.com, which is collecting intel Macs temperature. They’ve a nice step by step instruction on how to measure the temperature of your Intel Mac. I’ve submitted mine here, with the 100% CPU usage the max. temperature goes as high as 78 °C which seems to be the average load temperature of MBP. There are notebooks as hot as 93 °C. So, I think our MBP is not the worst one.
