ZM9500 + TT BT is lapped, Ninja is'nt.
Ninja has best bottom, not shiny but straight, perfect contact
1 problem, could'nt install my Mushkin RL XP4000 to DIMM4, first orange slot from S939, because 2 clips of cooler attachment to socket is in the way
PWMIC went HOT, because the last lamel is closed = nothing air flow to mobo
But very good cooler, no doubt!

Fan attachment is very poor, cant accept those iron wire tuning

But an nice clean wind tunnel should be very effective, now when my TT 120mm FAN blows trough Ninja and temps are that good so what then...
