Ever since I downloaded Snow leopard my fans are always on and the bottom of my unibody macbook is always hot. Anyone have a solution for this?? Thank you!
 
Beyond looking for Spotlight activity (which wouldn't be abnormal given the update) you can go to Activity Monitor (Applications-->Utilities) and change the drop down from "My Processes" to "All Processes" and see if something has hung and is eating up CPU cycles.

If it's not a system process (like Spotlight) you should be able to stop the process and watch your computer start to cool down pretty quickly.
 
ok i know how to fix your problem. go to google and search "smc fan control download" download that, run it, it should appear on ur menubar at the top that should say __˚F
__rpm
click on this, click preferences, then drag the blue ball all the way to the left, then hit save. this should make your computer sound much smoother, and u wont hear a thing. good luck! =)

That's not a fix....if his computer is overheating/running hot the absolute LAST thing you want to do is force the fans to run at a speed not spec'd by the OS!! :mad::mad:
 
Open up Activity Monitor (in Applications > Utilities) and in the drop-down on the right hand side of the toolbar, change to 'All Processes'. Sort the list by CPU use, and see if there is a process that is using a sizeable chunk of CPU time.
 
I've got a white 2Ghz C2D and when I surf the net and have mercury open fans hover between 3500-4000. I've done everything mentioned so far in this thread, no noticeable difference.
Is this normal, or should I send it to apple before the 3 year warranty expires in 3 weeks?

Does surfing have a lot of Flash video or Flash apps in it in your case? If yes, then it's Flash being a resource hog and yeah....nothing to do really.
 
I reckon its being caused by one of the following:

1. Some sort of system activity (spotlight indexing, for example).
2. Flash videos or flash games.
3. The fans set to run faster on Snow Leopard on your MacBook model.

The first reason will go away by itself, the second reason can be solved by avoiding flash on your Mac (http://factoidz.com/alternatives-to-using-flash-on-your-mac/). And I'm not sure what to do if its the third reason...
