Summary: Very easy to apply, nice that it's non-conductive so if you sneeze or something you don't accidentally bridge two electrical contacts somewhere and have to clean it up. Am using on the heatspreader of a 3570k overclocked to 4.6GHz (low flow water cooling setup) and my temps are well under the safe limit even under continuous load.
worth every penny. this is 20G so you will have this as long as you live!

Summary: i love this paste. Ive used it a few times from my desktops to my alienware laptop. I applied this to my alienware that was pushing 90*C on video and 80*C on processor hd5850m and q720m after cure time and letting run for 48hrs i ran a few tests max gpu was now 80*C max cpu is now 60*C just put a new video card in recently (gtx770m) not sure what it ran before but idle 38* full tilt 72* same in my pc i5 2500k was 82*C now 60*C
Summary: I used the Arctic MX-4 in conjunction with a Corsair H75 AIO watercooler and a NZXT Kraken G10 bracket to cool my GPU (EVGA 660ti). Temps with the reference cooler would easily reach over 70+ Celsius when pushed. Now I find it hard to push it past 40 Celsius. I'm sure that this thermal paste is much better that what I was using before (Arctic Silver 5). The price was a bit more, but you get so much of it. I'm sure I will never need to buy paste again.
