Intel® Celeron® D Processor 325J (256K Cache, 2.53 GHz, 533 MHz FSB)
The boxed Celeron D processor in the LGA775 package features a thermal solution designed by Intel to provide an effective cooling solution that matches the processor. The thermal solution includes a 4 pin connector for fan speed control to help minimize the acoustic noise levels .The acoustic benefits of the 4-pin header are reliant on a properly designed motherboard. Boxed Intel® Desktop boards based on Intel® 925X, 915 and 910 Express Chipsets were designed with support for acoustic benefits of the 4-pin header.
For Celeron D processors based platforms in the LGA775 package a Thermally Advantaged Chassis (TAC) based on TAC version 1.1 is highly recommended to assist in maintaining a required internal chassis temperature.
