Zalman CNSP7000A-Cu Heat Sink Review

Former staff writer    -   October 21, 2003


Testing

So let's get going on the good parts: What type of performance will this HSF give you.

Testing Setup
Abit KX7-333R
AMD Athlon XP 1800+ (1.53Ghz)
Corsair 512MB PC2700 (DDR333) CAS2.5
Lian Li PC70 w/ 6 Case Fans
Cramique Thermal Compound

Testing Method

Testing was conducted in the usual manner. Temperatures for the testing were taken via a CompU Nurse thermal probe located next to the CPU die. C�ramique (by Arctic Silver) thermal compound was applied to the CPU and each heat sink according to the directions located on Arctic Silver's web site. The compound was given 120 hours of use before testing was done on any of the heat sinks. To achieve the "idle temperature" reading, the computer was allowed to set idle for 15 minutes, and then the reading was taken. To achieve the "load temperature" CPU Burn-In was run for 15 minutes and then a reading was taken. The overclocked temperature readings were done in the same fashion, except that the system FSB had been increase from 133 to 145 giving the system a 138Mhz overclock.

Testing Results







As you can see from the testing results, the 7000A-Cu and the Aero 7+ were neck in neck in just about every result. The Aero 7+ actually barely (0.3C) out preformed the 7000A-Cu in the final test, which was the Overclocked Load temperature. The major advantage that the 7000A-Cu held was the noise level, which with both at full speed the 7000A-Cu was 28.3dB(A) quieter than the Aero 7+. This goes back to statements from the forum, and past Zalman reviews... the Zalman products are good if you want quiet, but if you are overclocking, you want something else.

Conclusion

Overall, the Zalman CNPS7000A-Cu is a good cooler, the major advantage to it though is the quietness about the cooler. This is expected though coming from the Computer Noise Prevention System line of products. If you are looking to eliminate computer noise, or just reduce the overall noise level of your system, this heat sink, in addition to other CNSP products can help you dramatically lower the noise level. As said before though, this heat sink is not very overclocking friendly, so special care should be taken if you like to overclock. In addition, be sure to check out the list of compatible motherboards from Zalman's web site if you do decide to purchase the 7000A-Cu.

Pros * All Copper
* Intel Pentium 4, AMD Athlon/Duron/Athlon XP, and AMD Athlon 64 compatible
* Quiet
* Fan speed controller (FAN MATE 1) included

Cons

* Not overclocking friendly
* No fan guard
* A bit expensive @ ~ $47.00 USD
* Not compatible with all motherboards
