its ok if you put a little 2 much paste on , i did that too and the temps were like 6*C hotter but i just let it settle in and it dropped like 10*C giving me good temps
I know exactly how you feel. I recently installed an AC Freezer 7 pro on my e660 and the same shi+. My temps started to idle at 46c...then 50c....so I waited to see if it would drop back to 46c...nope! I restarted and still high temps. I also used as5...reapplied smaller amount and same temps.
IMO, both of us got a lemon. I'm currently using stock hsf and oc'd to 3.42.
Anyway, I don't blame you for selling it as I've already listed mine on ebay.
Good luck
