Zalman CNPS 5100-Cu heatsink reviewFormer staff writer - July 25, 2002
Our testing method:
To get the idle results, I turned off the computer and allowed the system to cool for a few mins. Then I booted up in to windows and allowed the system to idle for 10mins before writing down the results.
In order to get the load temperature, I ran two Seti@home programs while running a SiSoft Burn in test.
I used a comp-u-nurse temp probe to get the temperature readings.
This test compares the idle and load temps between the Volcano 9 the Zalman CPNS6000-CU and the Zalman CNPS 5100-Cu. This test was also done with my case panel ON.
This test compares the idle and load temps between the Volcano 9 the Zalman CPNS6000-CU and the Zalman CNPS 5100-Cu. This test was done with my case panel OFF, to simulate what the temperatures would be like if I had some case fans installed and running.
The Zalman 5100-Cu did a fairly well job keeping up with the Volcano 9 in these tests. However, the Zalman 5100-Cu blew the Zalman CPNS 6000-Cu away! I just knew that this heatsink could cool my CPU better if it only had a really fast and high rated CFM fan blowing on it. So, I put my theory to the test and grabbed a 7200RPM Black Label delta fan off of my Global Win FOP32, and stuck it on the CNPS 5100-Cu.
Here are the results:

Some very impressive temps from the Zalman CNPS 5100-Cu! The Zalman CNPS 5100-Cu beat the Volcano 9 in a full load test, and came very close in the others. While, both the Volcano 9 and CPNS 5100-Cu blew the CPNS 6000-Cu away!
The Zalman CNPS 5100-Cu isn't a perfect heatsink, but it's fairly close. If it wasn't for the rough copper base, and the lengthy installation I might of given this product our OCC recommended award. However, I'm happy to say I don't regret taking the time to install this heatsink. I think the time consuming installation was worth every bit of the time. This would be a fine heatsink for an overclocker (if you use another fan), because you can remove the heatsink fairly easy, just zip out the four long bolts on top of the heatsink. Which is VERY good for users that have a tight computer case and can't get a screw driver in to undo heatsink clips. Just make sure you have the brass couplings fastened tightly against the motherboard or the four short screws on the other side, will go loose under your motherboard :)
I'd like to thank Zalmanusa.com for providing us this heatsink to review!
- Very good cooling
- Very quiet fan
- Fan controller
- Needs no space, to take off the heatsink vs conventional heatsinks
- Rough base
- Time consuming installation
