Product Reviews
- “...a tried and tested design that's been doing the rounds since Athlon XP days. Though this latest 'flower' is a lot bigger, it's still up to the task, running very quietly (as long as you stick the fan speed adjuster to minimum) and still cranking out a minimum of heat. Verdict: 80%”

Zalman CNPS7500 LED 110mm Super Flower Coolers
- Replaces the Zalman CNPS7700 120mm Super Flower Coolers
Better performance, easier installation!
These new additions to the famous Zalman 7000 series give guaranteed cooling satisfaction! They offer slightly improved performance to the CNPS7700 coolers and are smaller, lighter, have blue LED lighting and offer AM2 socket compatibility.
Product differences
The CNPS7500 is offered in two versions - copper (CU) and aluminium/copper hybrid (ALCU). Both coolers are identical except that the CU version is heavier and offers better cooling thanks to the superior conduction of copper versus aluminium. In practice this equates to a lower CPU running temperature of around 3°C for a high-end system. If you crave the lowest possible CPU temperature then we suggest you purchase the CU version, but otherwise the ALCU version still offers excellent performance and is less expensive.
Motherboard cooling
As with all Zalman's 7000 series coolers, the unique design of the product allows not only the processor to be cooled, but also its surrounding components as shown on the image below. Important components such as the Northbridge chip, RAM, VGA and FET circuitry receive a good share of the cooler's airflow, which increases their reliability and lifespan.
Compatibility considerations
Due to the smaller size of the CNPS7500 in comparison to the CNPS7700, there are generally very few compatibility issues in terms of clearances with motherboard components. However, please do check the Zalman website before purchase. PLEASE NOTE: Socket 775-based motherboards will need to be removed from the chassis to be able to install the CNPS7500.
The CNPS7500 is incompatible with Athlon XP (socket A, 462) and Pentium 3 (Socket 370).
Installation considerations
The copper version of the CNPS7500 exceeds Intel's suggested maximum heatsink weight, and so care must be taken when transporting a PC with this cooler installed. Neither we nor the manufacturer can be held responsible for any damage to a system or a CPU occurring when a PC is moved with an overweight heatsink in situ. UNDER NO CIRCUMSTANCES must a PC be transported by courier with this heatsink in place. The heatsink must be removed from the CPU before transporting the PC in order to prevent damage.
PLEASE 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").

Okay here goes...
What a piece of KIT... it comes with all the fixing brackets and fan controller what more do you need nothing.
Pros
Very nice fan to look at, reduced my CPU temp from 48 to 29 using the fan controller at its max of 2400rpm when reduced to the min which is silent it reached 35 which is amazing and proves the heat sink does its job.
Cons
Not enough paste just the one chance to get it right, very large fan so I would only use in a ATX case. The copper fins are really fragile so be carefully on installation.
Overall very pleased and would buy another one with the performance it gives.
