Semi-passive Kit for ATX power supplies

Semi-passive kit for the do-it-yourself modification of power supplies includes

• integrated linear digital Band-Gap sensor
• mounting on the heatsink
• external control of the power supply fan via mainboard or fan control
• power supply fan switch off during sleep mode, and temperature sensitive through external fan controller
• temperature reading with SMBus or I2C-Bus (e.g. T-Balancer)
• overheating protection: 80°C on, 75°C off

With the temperature control you can control graphic cards, processor fans, chassis fans but not the power supply fan. 

With the semi-passive kit you can modify your power supply to work with external fan controls and to enable various kind of modes, like the semipassive cooling mode. The modification is very easy. The digital sensor will be placed on the main heatsink in the power supply. Sensor cable and fan cable will be connected to the outside.

For example, with a good temperature control, you can enable the following modes:

With the help of the SMBus or I2C-Bus you can also read the precise actual temperatures of the digital sensor (e.g. with the T-Balancer).

This semi-passive kit does not need an own power supply. It is easily connected to the power cable just before the fan. The sensor will be fixed (screwed) to the main heatsink.

Specifications:

• 30 x 20 mm
