Overclocking needs

chances are you are not gonna be able to overclock the i5 due to it being in a laptop and the BIOS is prolly locked...but to oc the gpu try using msi afterburner idk if you can or not but give it a shot

Your only optiond on overclocking on a laptop that has a locked bios is by software. The MSI Afterburner is one and Riva tuner is another. there are some software choices at this link that you can try.

but im talking about if i should buy a cooler master and artic paste and stuff so it doesnt get too hot

by cooler master you mean a cooling pad right? if so then yea sure you could do both of those things and it will help keep the temps down but you still wont be able to OC the cpu

but the gpu yes

yep you could overclock the gpu using msi afterburner or something else..just keep an eye on the temps and the thermal paste and cooling pad will help that.
