Zalman CNPS5500-Cu Review - Zalman CNPS5500 - Page 4

In recent years, we have seen new heatsink manufacturers pop up all over the place. Most boasting a unique, innovative design method, fighting for a place in an already crowded market. Today we are looking at a new heatsink/fan unit from Zalman, called the CNPS5500-Cu. Zalman is a Korean company that was founded in 1999, and since the introduction of their CNPS (Computer Noise Prevention System) range of coolers, they have received much praise for being able to create heatsink/fan units that are high performing, yet virtually silent. Can they continue their trend with the CNPS5500-Cu? Join Asher "Acid" Moses as he attemps to find out!

Processor: Intel Pentium 4 2GHz


Motherboard: Abit BD7-RAID


Memory: OCZ 256MB PC2100 DDR SDRAM


Video Card: Prolink Pixelview GeForce3 XX-Player


Hard Disk: Quantum Fireball Plus LM 15GB 7200RPM


Case: Lian-Li PC65


Operating System: Windows 2000 Professional


Software Used: Winbond Hardware Doctor


To measure temperatures and fan speed, I used Winbond's Hardware Doctor application. I measured idle and full load temperatures in "Normal" and "Silent" mode. I then compared these results to my stock Intel heatsink/fan unit that comes with the Pentium 4 processor.




- Zalman CNPS5500 "Normal Mode"



- Zalman CNPS5500 "Silent Mode"



- Stock Intel





- Zalman CNPS5500 "Normal Mode"



- Zalman CNPS5500 "Silent Mode"



- Stock Intel



For those of you that do not know how to interpret the above information, I have set it out in two easy-to-read graphs.




As you can see from the above results, the CNPS5500's performance is nothing special. When idle, the Stock Intel heatsink/fan outperformed the CNPS5500 (Normal) by 2.5 degrees, and the CNPS5500 (Silent) by 3 degrees. When at full load, the CNPS5500 (Normal) managed to move slightly ahead of the Stock Intel unit by 1.5 degrees and the CNPS5500 (Silent) by 4.5 degrees. While there isn't much difference between the two units, I must say I was expecting its performance to be slightly better than that.


Another thing worth noting is that at both "Normal" and "Silent" modes, the CNPS5500 was very quiet, however, I didn't notice too much difference between the two. For optimal performance and a more than tolerable noise level, I recommend leaving it at the "Normal" setting. The stock Intel heatsink/fan unit ran slightly louder than the CNPS5500 but as I stated earlier, the difference isn't really noticeable.
