Product Details - Zalman CNPS7500-AlCu LED Ultra Quiet Aluminum Copper CPU Cooler
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 aluminum/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 aluminum. 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 issues
Due to the smaller size of the CNPS7500 in comparison to the CNPS7700, there are no known compatibility issues in terms of clearances with motherboard components. 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”).
