Datasheet Volume One

The STS200C utilizes a fan capable of 4-pin pulse width modulated (PWM) control. Use 

of a 4-pin PWM controlled active thermal solution helps customers meet acoustic 

targets in pedestal platforms through the baseboard’s ability to directly control the RPM 
of the processor heat sink fan. See 

 for more details on fan speed control. 

Also see 

 for more on the 

PWM and PECI interface along with Digital Thermal Sensors (DTS).

The STS200P and STS200PNRW are available for use with boxed processors that have 

TDP’s of 130W and lower. These 25.5 mm Tall passive solutions are designed to be used 

in SSI Blades, 1U, and 2U chassis where ducting is present. The use of a 25.5 mm Tall 
heatsink in a 2U chassis is recommended to achieve a lower heatsink T

LA

 and more 

flexibility in system design optimization.
