My new laptop Dell 1525 makes a whirring noise every 30 seconds.

I received my laptop less than a week ago and ever since I turned it on I've been noticing a whirring type of sound comming from the back of the laptop.  It exhausts a lot of heat when it makes the sound.  What is the problem and how can I have this resolved?

Obviously its the CPU heatsink fan starting up when the CPU needs cooling.
You could monitor the temps  especially the CPU temp to see if its keeping it cool enough.
also here is a link for software that monitors fan speed, cpu temp, etc...

Thanks guys for the links.  I will check these out.  In the meantime, I have to find a way to quiet the cpu fans a little more.

I downloaded the software that you recommended.  Should I manually set my first and secondary fans to slow?  I don't mind a little humming comming from the laptop as long as it's not too loud.  
No, you should monitor the temps first in order to make sure it isn't overheating. What temperatures are you getting from the software when running normally, and running a demanding application. This should give some indication of the trip point where the fan starts up and when it slows down. Then you can taylor the fan speeds to keep a consistent temp.
Is the fan stopping or is it just running slowly when you can't hear it?
Forced accept.
