Compatibility Intel Xeon socket 603/604/771 Type 50xx/51xx/53xx/54xx (FSB 667/1066/1333/1600 MHz) Woodcrest/Dempsey/Clovertoen/Wolfdale/Harpertown, all clock speeds! The cooler is not directly suitable for socket 603/604 (FSB <=533MHz) - you will have to use the optional backplate in order to be able to mount the cooler. Not suitable for Intel Chassis SC5299BRP. |

Gerneral information The Verax X21NGA allows you to cool you Intel XEON system quiet and efficient. The high performance heatsink with three integrated U-shaped heatpipes tranfers the heat efficiently from the copper base to the fins. The cooler is designed for use with Dual-CPU systems. The quiet 80mm fan has the Verax PWM/T technology integrated. The PWM/T technology uses the temperature and the PWM-Signal of the board to calculate the required fan speed. At low temperatures the heatsink has enough capacity to store the additional heat so an increase of the fan speed is not necessary even if the PWM-Signal of the board requests an increase of the fan speed. At higher temperatures the heatsink cannot buffer more heat so if the board indicates to raise the fan speed due to more system load the fan increases it?s speed directly. So in other words: the influence of the PWM-Signal increases with the temperature. That avoids short-term increases of the fan speed due to short-term high system load situations. If the Verax fan does not get a PWM-Signal it behaves like a normal temperature controlled fan, so it is possible to use it with or without PWM-Signal. The heatsink can be mounted on socket 771. Using the included washers it is also possible to mount the heatsink on a socket 603/604 system. The cooler can also be used on systems which do not support PWM. The integrated temperature sensor will control the fan speed then automatically. |
