Zalman 9500AT Intel 775 CPU Cooler

The only metal part of the cooler that is not copper is the aluminum bracket that holds the fan firmly into place. This bracket doesn’t affect the cooling performance on the cooler whatsoever though.

Before I install the cooler, I took a shot of the cooler compared to my cell phone, and a 120mm fan. There’s no denying the size of this beast! You best be ready to clear out your case to fit it in ;)

Here are the official specs for the entire unit. As mentioned in the introduction, this cooler is for Intel socket 775 -only-, which CPU’s include Celeron D, Pentium D, Pentium EE and Pentium 4 EE.

• Main Function – PWM Control Function and Auto Restart Function

Features
• Compatible with Intel’s Dual Core Pentium, Pentium4, and Celeron D for Socket 775.
• Low-noise 92mm PWM Control fan for automatic control of the fan’s RPM according to CPU temperature.
• Optimized heatsink layout composed of pure copper for maximum heatsink efficiency.
• Innovative, patented, and curved heatpipe design for a heat transfer capacity of up to six heatpipes with just three.
• 0.2mm ultra-slim fins for minimized weight and reduced airflow resistance.
• Maintains minimum RPM even when Duty signal supplied by M/B is below 30%.
• Operates in silence by preventing extreme RPM during initial booting.

Now that they are out of the way, let’s jump into the installation.
