Hey guys, finally got my rig in the mail and put together, thanks for all your help its awesome 
But I have a question in regards to the i7 2600 sandybridge temps.
I put the whole rig together 2 days ago, and so far havnt had any problems, except I downloaded CoreTemp just to see what the temps read at (I dont OC or anything) this was after it had been running for a few hours idle (downloading sc2) and the temps would read around 48-50c, I ran sc2/counter-strike source, tf2, and WoW (not at the same time) and the temps would only go up to about 60c give or take 1-2 degrees, maybe once up to 65c, I didn't think it was a big deal, since they havn't really gone much passed those temps but it seemed a little high, even though it had been on 3 hours or so I was only using firefox and the blizzard downloader, and when gaming it wouldnt rise to much, but 65c seemed a little much, considering I could touch the heat sink all day and it only felt "warm" even when I turned the computer off hours later.
I've browsed the forums and saw that the temp readers could be off, the thermal compound could have been applied incorrectly, it could be to new of a rig to get the right readings? I am using the stock cooler but removed the thermal pads strips that came on it and applied a thin layer of as5 to the whole copper underside, spread with a card, but what would your suggestions be? Just keep an eye on it? Remove the thermal paste and apply the rice size dot and let the heatsink spread it (instead of me)? or if its nothing to worry about right now?
I will get an aftermarket heatsink asap, but wondering if theres something I should change in the meantime.
Thanks for all your help guys, sorry for the long explanation.
