Design and Functionality
Please meet ASUS Silent Knight II:
You can easily notice that it looks exactly like the first ASUS Silent Knight without any constructive differences. The cooler is based on six copper heatpipes originating from a copper base plate. The heatpipes are split in two groups, three in each. Each group holds its parts of the heatsink made of thin copper plates:
The heatsink array consists of 128 plates total. ASUS Silent Knight II measures 115 x 140 x 110 mm and weighs 610g. So, what has become different compared with the previous cooler revision? I believe you will be disappointed with the answer: the changes touched only upon the fan installed between the two parts of the heatsink. Now instead of a fan with constant rotation speed of ~2,200RPM, Silent Knight II feature a 92mm fan with maximum ~2,300RPM rotation speed and PWM control support. So, the old-new cooler has become much quieter when the CPU utilization is low, although under maximum workload it turned a little noisier.
Unfortunately, the quality of the base finish got a little worse. Now there is no mirror shining polish:
Although the surface remained as impeccably even as it used to be: the thermal compound imprint on the glass surface was ideal.
