Zalman’s 6500B-AlCu / 6500B-Cu coolers have an extended heat dissipating
area and include a new fan assembly (FB123) with an adjustable bracket and a
bigger fan (92mm) for maximum cooling performance. 

* The specifications of any product may change without prior notice to improve the performance thereof.

1. Features 

1) Zalman’s CPU Coolers do not generate noise and vibration in Silent Mode.

2) Separation of the FHS from the CPU fan prevents transfer of the fan's vibration to the CPU. 
3)

By utilizing a 92mm fan, both the CPU and the motherboard chipset are cooled. 

4)

The cooling fan can be mounted at any desired location making it compatible with   

virtually all computer cases and motherboards

(Note : computer cases that have the power supply covering  the CPU cannot be used). 

5)

With the included adjustable fan speed connector, the user can freely adjust the  
CPU fan's RPM.

6) Zalman’s CPU Coolers enable very stable operation of a CPU in an OVERCLOCKED  

environment.

*   When OVERCLOCKING, please make sure to use Normal Mode.

*  Zalman Tech. Co., Ltd. is not responsible for any damage to a system or a CPU

caused by CPU OVERCLOCKING.
