MacBook (Aluminum) Fan Running at 5053rpm? Normal?

I didn't want to stress the fans, burn them out. I used Photoshop, Safari, iChat, iTunes.

How does the fan work? Does it assume that if you have many apps open if has to go to a high rpm?

or temp?

CPU load drives up the temperature and the fans kick in as a result to cool the laptop. It's barely an inch so keeping it cool is going to be tough but possible.

Why are you worried about the fans? The MTBF isn't even near. 😕
 
mine's running at around 2000RPM always. regardless of load or temp.
I use iStat to monitor it.
 
why run the fans higher than they need to be? use the standard fanspeed/cpu temp relationship to manage the speed. theres no point in running them faster than they need to be, if the cpu heats up then the fans will speed up to keep that heat under control, simple as that
 
highest i got the fan was 5000rpm using visualhub converting files. Thats about as fast as ive seen mine according to istat.
 
fan speed constant

i have a macbook 2.4 alum, and the fan gradually goes up to 6050rpm and remains constant, it never stops until i restart. is that a software or hardware issue?
 
when your fans are going up that high look in the activity monitor and see what application is using all of your CPU
 
u r right

the problem is that if your fan starts gradually and then goes up to 6000 rpm and stays there until reboot, so there is process which is heating up the cpu, mine was the iantivirus which i installed,...

no matter how much load u put on , there was something wrong, i read many forums and thought that its the hardware, some said it was a stuck print job some sid to reset the smc, but even after doing that , nothing happened when i uninstalled regardless of restarting my macbook , now things are smooth, i run nfs carbon, im in bangkok, and my rooms a/c is off, so i made the temperature around 30 degress cents... so still now my macbook runs excellent, the problem was i antivirus..🙂🙂🙂🙂
