OK, I received the new Zalman CNPS9500AT CPU cooler and installed it about a week ago. Thus far, I am very impressed with the unit.
1- The original stock unit could get pretty noisy at times as the CPU fan speed increased. The Zalman unit dissipates heat so well, the fan has yet to increase to a very high RPM level as experienced with my stock unit. But, even at moderate RPM levels it is super quiet!
2- Idle temperatures are roughly the same as with the original stock unit ........ maybe 1 or 2 degrees C less. But, with normal multitasking, I am experiencing temperatures as much as 7 degrees C cooler. Supposedly, these temperatures will decrease more as the Artic Silver 5 "ages".
So, once again, I am very satisfied and would recommend this unit to others. Just remember, the AT model is for automatic control and has the 4 wire lead.
Hope this is helpful for someone!
