Hawaii!
So i noticed that my fans didn't kick on past the normal 2000 rpm until my CPU temp hit 71, GPU diode hit 71, and the GPU heatsink was at 61. Is this normal?
 
My fans idle around 2k rpm until I do something that is processor heavy i.e. export/convert videos, play video/games, etc. But they don't when I'm web surfing, idling, listening to music, or doing homework.

What are you doing that's making your computer reach that temp?
 
use smcfancontrol to set a higher default speed, it works much better than on/off fans at extremes
 
My macbook (not pro) fans come on when I'm just using Safari. Only occasionally are they not on.

Is that normal?
 
Yea, the MBP fans(at least the Penryn) usually hovers at 2000rpm, and will only speed up if it gets really hot. I love SMCfancontrol since I can just keep the fans at 3500-4000RPM constant(it is barely audible at that speed), it keeps the MBP cool to the touch and comfortable.
 
Is that with a Macbook?

No. It's MBP C2D (Pre-Penryn).

Is the Pro better at keeping quiet as the fan is very annoying on the Macbook and seems to be going 90% of the time.

Yes. Most of the time my MBP is very quiet (keep fans at about 2000rpm). The problem occurs only in Safari and it is quite annoying (fans up to about 3500rpm, maybe a little more).

Thanks for the info. Another reason to switch to firefox then.
 
Fan speeds left to default will stay around 2000rpm even when reaching CPU temps of 70-80 degrees Celsius.

Use smcFanControl to change the default speeds. In the app, I keep settings for 2000, 4000, and the maximum 6000rpm. I find increasing the speed in increments of 2000 reduces the CPU temp about 7-10 degrees Celsius.

So yeah, I like that app.
