bro, u sure u using sd963 or sd964? cuz the pic u posted is showing a sd964 with 4 heatpipes.

btw tunix really could do that good? im having a sd964 now and im using the stock thermal paste it came with. (kinda hook the xigmatek hsf up to my rig in a rush and didnt order any other thermal paste cuz i need to go back hometown from my hostel that time),

my proc is e6750 oced to 3.2ghz (400x8); vcore:1.35, idle temp is 33-37 (depends on room temp), while full cpu stress temp is 59-60. no aircond.

so i would just like to know is it really worth it that i should get the tunix or just stick with what i have now. thanks!
