M17X-R4 Full Upgrade (3940XM and GTX 880M)


Recommended Posts

Hello guys, I'm new to the forum (I own an Alienware M17X-R4) and I'm thinking of upgrading my i7 3630QM to a 3940XM and my GTX680M to the GTX880M, I do know that my PSU won't be able to power those components (correct me if I'm wrong) as the difference in TDP from my current setup is about 30W and the power consumption will rise with the overclocks... so I'm planning to do this mod and run it all with the M18X PSU, but one thing that I don't know is if the CPU heatsink needs to be modded in order to properly cool the new processor... I saw a thread about this same CPU upgrade on TechInferno and references to a "triple heatpipe heatsink" for the M17, but nothing that I could get enough information from... (no part number, etc...) So if any of you guys could help me, it would be great :D
