Looking for the ultimate air cooling solution for your Intel 775? The Zalman 9500AT may be up your alley, but may prove a little pricey for your liking. Installation proved a little problematic, but the cooling ability is evident.

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.
