    Zalman CNPS6000-Cu Heat Sink Review

    (Page 1 of 2 )

    A little while ago we reviewed the kickass Zalman CNPS6500A-Cu which was outstanding in performance. It generated very little noise and was able to keep temperatures very low--an overclocker's dream. Today we have the Zalman CNPS6000-Cu up for review. Will it perform as well as its bigger brother? We shall find out.



    A little information about Zalman products before we move on to the details of the CNPS6000-Cu:

    1. Zalman's CPU Coolers do not generate noise and vibration in Silent Mode.
    2. The heat dissipating material of the Flower HeatSink (FHS) is Pure Copper.
    3. Separation of the FHS from the CPU fan prevents transfer of the fan's vibration to the CPU.
    4. By utilizing a 92mm fan, both the CPU and the motherboard chipset are cooled.
    5. 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 can not be used).
    6. With the included adjustable fan speed connector, the user can freely adjust the CPU fan's RPM.
    7. CPU can be cooled to a temperature sufficiently below the temperature required by the CPU manufacturer in Silent Mode.
    8. Zalman's CPU Coolers enable very stable operation of a CPU in an OVERCLOCKED environment.

    Zalman labels all their heatsinks with “CNPS”. What does “CNPS” stand for you may ask? “CNPS” stands for “Computer Noise Prevention System”. Zalman’s main goal in the computer business is to make your computer completely silent. They make CNPS CPU heatsinks, northbridge and gpu heatsinks, and power supplies. Checking on the Zalman site gives you their suggestions of hard drives for complete noiseless systems.


    In terms of size, the CNPS6000-Cu is much smaller than the CNPS6500A-Cu. It doesn't make much sense to me when AMD processors produce more heat than Intel processors. I guess some things will never be explained. The heatsink is made of copper fins spread out like a flower. There is a central gap for the use of a clip. Another question that jumped to my mind was why Zalman didn't use the motherboard holes for installation and still went with the clip. Using screws and springs to install the heatsink through motherboard holes is much safer for other hardware parts. There is no worry of your heatsink falling off and crashing through multiple cards. The bottom of the heatsink was nicely lapped and has a shiny finish to it. The tube of Arctic Silver reflected very well.


    Packaged with the CNPS6000-Cu were two clips--just in case for those who make boo boos... There was also a installation tool for pushing down the clip to hook on to the socket. This is a definite plus over the use of a flathead. It has been specially designed so that it won't slip and punch a hole in your motherboard (heh...YOU know what I'm talking about).

    As with all their heatsinks, Zalman has included a fanmate for those noise freaks like me who need absolute silence while computing.  

    Like the bigger brother CNPS6500A-Cu, the 6000 went over the weight limit of the AMD and Intel recommendation. The limit for the socket370 is 180g while the limit for socketA is 300g. The CNPS6000-Cu weighs at a hefty 462g.


    The 92mm fan that comes packaged with the heatsink is rated to run very quietly. In normal mode, it only produces 33dBA. In silent mode, it produces a measly 20dBA. There was no real point in running the fan in silent mode as the normal mode is already pretty much silent. I could hardly hear a thing. I think my power supply was louder than the heatsink fan. Attaching the fanmate and powering the fan to max speed produced more CFM but sacrificed quietness. The fan could be heard but it’s definitely not annoying. And DEFINITELY no Delta.

    Let's see how this baby performs and wrap it up.....
