Product Reviews
- “If you’re trying to build a quiet PC you should take a look at the CNPS7000A-ALCU, and if you’ve got a case with a clear side panel you’ll want it even more.”
Zalman CNPS7000B Super Flower Coolers
- Replaced by the Zalman CNPS7000C Super Flower Coolers
The CNPS7000B "Super Flower" offers a low-noise 92mm fan which is cleverly integrated into its radial heatsink itself. Available for Pentium 4, Athlon 64 and Athlon XP, its striking design offers unparalleled efficiency even when its fan is running in "Silent mode" (a mere 1,350 rpm).
The CNPS7000-CU achieved a full 6 out of 6 stars in PC Pro magazine and even scooped the coveted "Extreme Most Wanted" award! For a specialist component, this alone speaks volumes. But what really hammers the point home is the product's ability to cool processors up to a theoretical 150 watts!
"Zalman still rules the roost with its Flower Cooler approach." - PC Pro Magazine, Jan 2004 p.299. (CNPS7000-CU vs Thermalright SLK-947U comparative review).
Socket types
Compatibility Issues
Due to the diameter of the CNPS7000B there are a few points to consider before purchase. Zalman state that no motherboard components with a height greater that 39mm as well as the PSU, disk drives, VGA card, and RAM should be present within a 55mm radius from the center of the CPU.
Zalman have released a comprehensive list of compatible motherboards. Please follow these links depending on your motherboard socket type: Pentium 4 (S478), Athlon 64 (S754/939/940), and Athlon XP (S462/A/7).
Socket 775 compatibility is achieved by using Zalman's ZM-CS1 clips, available separately. This clip has been specifically designed for the 7000 series only. If you can not determine if your motherboard is compatible then you are asked to measure your motherboard to ascertain compatibility.
PLEASE NOTE: Your motherboard may need to be removed from the chassis to be able to install the CNPS7000B.
NOTE: Some motherboards have difficulty measuring low fan RPM speeds on coolers such as this one. The problem can sometimes be fixed by updating the motherboard BIOS to the latest version available on the motherboard manufacturer's website. However, with some motherboards, the problem remains. Regardless, this will not affect performance. In addition, some motherboards will not boot if the CPU fan speed cannot be measured, as a safety feature. After rotating the Fan Mate speed control fully clockwise to enable booting, this feature needs to be disabled in the BIOS setup (set "CPU Fan Detect" or similar to "Disabled").
