How long till temps are at mid 30c and mid 40c's?

I just upgraded to a Core i5 3570k and i'm using Arctic silver thermal paste just as the title says how long till the paste sets in so I wont have to worry about the temps overheating? and my cooler is a Corsair h60 2012 edition fyi. thx fellas. :) 

Umm, sorry to break it to you, but you probably aren't going to see them stay that low if you overclock past 4.2 GHz. The H60 is nice, but it doesn't have enough metal to keep a quad core cool with a healthy overclock. But to answer your actual question: 24-48 hours. Make sure you power your computer on and off a couple times a day, letting it cool completely before turning it back on. The methodology is explained on their website, if you look under their support page they give you a thorough application and burn-in guide.

it says 200 hours i believe, but the biggest difference will be the first 12-24 hours, just make sure you stress test the CPU to help it set.

Cool thanks beyond ya I'm just installing all my games and web surfing hopefully that will help set the paste quicker :)
