Why the desire to upgrade? Are you seeing overheat issues and/or lots of fan activity?

Lots of threads about modding the XPS 8930 on this forum, like this one, so search for them and have a read...

I have read them but for some reason, I didn't see what i am looking for. I'm not the sharpest tool in the shed so may have overlooked it. I need to know the clearance room available for the CPU cooler. I am handicapped and would rather find an answer to it before pulling it apart to upgrade it. All my cores are hitting low 200 F.  Sorry for being rusty at all this.

@NerdyTechFlea  If you install the same model fan(s) and heat sink that others have already used in the XPS 8930, you shouldn't have a problem, even if you don't know exact clearance measurements, simply because they already got everything to fit.

You could always ask this question in one of those other threads because users who've already done these mods might have the specific answer you want. Be sure to mention exactly which CPU you have now, if you post in one of those thread.

200ºF (99ºC) is getting up there so I see why you'd want to improve the cooling...

Thank you very much for the info. 

I think many people re facing this issue and demand to move upgradation. May be this information will be helpful for them.
