Yes I'm 100% positive its seated properly. I've seated and reseated I don't know how many times. My old X2 loaded at 82-83*C on the hotter core in this puppy. Its the airflow in this stupid case....it has NONE! All the fan spots are maxed out with the highest CFM fans I could get. Doesn't matter if the case has extremely restrictive mesh over them though. That and the Zalman 9500 is notorious for being a horrible cooler at such a high price. I really shoulda been part of OCN when I put this thing together, lol. I'd have an e6300 and an 8800GTS 320MB if I woulda been here, lol. Spent $2k on it back in March of last year...with a $179 7600GT and an X2 3800+ Manny that got to a whopping 2.5GHz.
In all honesty.....I think I'm going to have to start looking for a bolt down BT or a Gemeni or something else that blows down at the mobo. My fiance's rig loads at 65*C with her BT at 1.50v...with the same X2 that loaded at 83*C in my rig with my Zalman (she also has the same case). And in my rig, that chip was at 1.35v (stock). So yeah....its the airflow....not the seating of the cooler, lol. I've gone through 2 complete tubes of Shin Etsu trying to get this sucker seated right, lol.
guess I made the right decision? lol
