If i want to upgrade my processor in my laptop from a i5-3210M to an i7-3610QM what else, if anything would i need to change? They both have the same sockets, I"m thinking i might need to upgrade the fan, but is this necessary?
I'm assuming that you have experience taking apart laptops.
First, the socket. It's the same socket on both CPUs (rPGA988B), but make sure your CPU isn't soldered on (it appears that the socket is a pin-socket, but it may vary between OEMs)
Second, the cooling. What are your (1-hour+) load temperatures right now? If they're below 80, then there should be just enough headroom for your 40% increase in heat. If they're hitting 80+, I'd recommend not upgrading, unless there a version of your laptop with a higher-power processor. If the higher-power version has the same heatsink, then you're fine; if it has a bigger heatsink, get the bigger heatsink as well.
For information on heatsink sizes, check Ebay / similar - that's how I upgraded my own laptop heatsink.
