Fan shouldn't be taking too much power at all. What way does the fan blow, up or down? There are some fans that blow up and some that blow down, and each laptop is better with one and worse off with the other. If you can borrow someones cooler that blows the opposite way give that a shot. I have a Dell StudioXPS and mine gets insanely hot when I have a cooler that blows down, but when it blows up I am perfectly fine, and my laptop never runs above 60c.
Another thing is you could look into undervolting your processor. Has had huge effects on my laptops, as well as family and friends (and even a bunch on OCN). I am actively working in that thread if help is needed, so give that a shot maybe:
It can't hurt at all. Only problem is stress testing
Once you do get it though write down the values so on a reinstall, you know them.
