Fan always on?

[phas3]

okay so I'm looking at my istat pro widget and says my fan is running at 3450 rpms is that normal and am i suppose to only have one fan. what is normal

i have a new macbook 2.4ghz Intel core duo w 2gb ram

Yes, one fan is normal. Are you running CPU-intensive games or applications like Photoshop? That could be why your fan is running a lot. Mine usually runs at 1750 rpm.

Idles at 1800 RPM and a maximum of 6200.

i like to mess with photoshop and other adobe products so if its running around 3k rpm i should have nothing to worry about? how bout if its running like that for awhile

It is normal.

That seems pretty normal, mine when it is running at its low and normal speed is 1793 rpm, and when the CPU starts to reach high temperatures (180 F) the fan hits about 6200 rpm, so I would say that it is normal for some somewhat CPU heavy software.

if i where to upgrade to 4g of ram would that make the heat off the laptop cooler?

It isn't running hot right now if you are running those programs. That is very normal and a lot cooler than a PC would. Is this your first laptop?

Because your laptop doesn't have a real GPU to offload video processing, or you're watching a flash video (which just love to gobble up CPU). It's nothing to worry about, laptops will get very, very hot but have components built to withstand the rigors.

I would consider looking into a program like SMC fan control.

Like your widget, it monitors your fan speed, however you are also able to set the default speed of your device fan. I actually cranked mine up about 200 RPM from default, and found that it went to high speed much less often when doing small periods of processor intensive work.

thanks for the reply guys, i do have smc fan control but i do not know how fast i should run my fans any suggestions?

Because your GPU got hot and something needs to cool it off.

i set my default rpm to 2800 is that alright?

A little noisy but it's fine.
