1. Features
1) Compatible with Intel’s Dual Core Pentium, Pentium 4, and Celeron D for Socket 775.
2) Low-noise 92mm PWM Control fan for automatic control of the fan’s RPM according to CPU
temperature.
3) Optimized heatsink layout composed of pure copper for maximum heatsink efficiency.
4) Innovative, patented, and curved heatpipe design for a heat transfer capacity of up to six heatpipes with
just three.
5) 0.2mm ultra-slim fins for minimized weight and reduced airflow resistance.
6) Fan never fails to stop operating because it maintains minimum RPM even when Duty signal supplied
by M/B is below 30%.
7) Operates in silence by preventing extreme RPM during initial booting.

②②
Install Clip Support
Align the Clip Support for Socket 775 ( ⑥ ) and the Backplate for Socket 775( ⑦ ) with the mounting
holes of the motherboard and fasten them together by using the Clip Support Fixing Bolts ( ⑤ ).
The Lever Slot on the Clip Support ( ⑥ ) should be properly oriented on the hinged side of the Socket
Lever when installing.
※※
The Backplate Support on the Backplate for Socket 775 ( ⑦ ) can be removed if deemed
unnecessary.
③③
Apply Thermal Grease
Clean off particles and residue from the top of
the CPU. Then spread the included thermal
grease ( ② ) on top of the CPU.

Install Cooler
Insert two bolts (④) into the holes on the clip (③) and place CNPS9500 AT on the center of the CPU.
CNPS9500 AT must be aligned with the backside system fan in the same flow direction.
Slightly fasten the bolts (④) on the holes of the clip supports for Socket 775 (⑥), then fasten the
bolts in an alternating manner until the clip (③) is completely pressed against the clip supports.

13. Home Theater PC Enclosures
TNN Computer Enclosures are the world’s first environment-friendly noiseless computer enclosures
that operate without the use of a fan. TNN Computer Enclosures use the aluminum enclosure itself
as a heatsink. They are ideal for environments that require silence, as well as for home theatre
systems and multi-media systems.
The HD160 is designed for ultra quiet home theatre
PC operation, utilizing optimized ventilation and
anti-vibration reinforcements, making it ideal for
environments that require silence such as living
rooms, bedrooms, educational facilities, and offices.
