If you still need some tips, there are a lot of things you can do however many require you to void your warranty. Do you know what motherboard you're using? If it's a 360 Elite you'll be using a Jasper, and really don't have to worry about the dreaded RRoD. However if you have an older model, I'd recommend getting an aftermarket fan put on, or a new heatsink. Replacing the thermal paste on your cpu and gpu with some high quality stuff like Arctic Silver is also a really simple process that actually helps a lot. And hey, if you have money to blow, go water cooling. I'd love to answer any questions about this, so feel free to ask.
