Motherboard MOSFET/Northbridge cooling ideas

Hey all,

I've been browsing Tom's Hardware for a little over two months now, and it's time that I post a quick question.

I recently built my own computer. I've noticed that my mosfets and northbridge get hot to the touch, not scoldingly hot, but definitely above warm. Can anyone offer any cooling solution? I've read that keeping the mosfet temps low will increase performance.

Thanks!

If you can touch them without burning your hand, then they are not too hot. Don't worry about it.
