Macbook Pro running hot

Okay so I installed SL around Christmas time. I was away for a week around New Years. Come back and for some reason my Unibody Macbook Pro runs at 150-165 degrees F while idle and using roughly 5% of my resources. It use to run at 120 before. I mean it even runs the fanspeed over 3k RPM to maintain that when I watch a simple youtube video.

Now I tried doing the batter reset, but that only fixed the problem for 2 days and then boom back to 150 degrees again. Now should I go to an Apple store and ask them to replace my battery. Or is there something else that I could do to avoid the time spent at the store.

Macbook Pro Unibody 08, Mac OS X (10.6.2)

I have a MacBook pro from last year and was having problems with the fan running at 6K and the temp flat refusing to go down. I tried all the standard things that are recommended by Apple. I am an Apple Certified Mac Tech. So I ended up ordering a logic board and all ended up being well with the world. The fan stopped running and the temps went back to normal.

I had reset the SMC, PRAM backed up the HD via TM and did a fresh install with all the current updates. Still problems with a standard load before the logic board was replaced. So the logic board was the issue.

Now recently, I started to have the problems again. I went back and thought about what had recently changed. I had loaded up PC Tools anti virus application. I disabled it and my temps dropped back to 133 F. from 186 F. The activity monitor showed that the Dashboard client was the most active application.

I know that anti virus is really not need on a Mac but I work at school systems and I am just a bit paranoid about attacks. The kids are creative!

I used to have a MacBook from 2008 and never had the problems with that running hot with a similar configuration.
