Ideally what I'd like to do is pull the PWM control from the fan header on the GPU, and put that into some kind of controller to adjust the speed of ... has a DC variable resistor rather than ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Horton Inc. says its VMaster and Stratis Di Viscous Fan Drive and Controller systems offer an economical choice for customers who seek the flexibility of variable speed along with optimal engine ...

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

Cons: The fan speed sensing is disabled ... If desired, R1 and R2 can be replaced with 22K variable preset resistors to allow exact tailoring of the control range. Varying R1 will alter the ...

A new variable-speed fan drive system with gearbox from ... WindMaster or WindShift fan, Di Controller and Hub City Right-Angel gearbox. It can be retrofitted to replace hydraulic and other ...

ICs in this category share many common features, including one or more temperature sensors, variable fan drive, tachometer input, communications bus and a fan speed control algorithm. However ...

It is not uncommon to see a variable-speed fan in the second ventilation stage while the first-stage fan is running at full speed. This scenario should be avoided. One fan controller that implements ...

Being a mains-powered fan makes it great as a desk fan, as I can just plug it in, but I'd like to improve it:<BR><BR>I'd like to have some sort of speed control for it, as at full bore it is not ...

BorgWarner’s Cool Logic variable speed fan drives are now standard ... when compared to traditional fan drives. The fan drives continuously check engine control modules to electronically vary ...

Variable-speed fan drives rotate the fan at a wider range ... can operate at low speeds and align more closely with an engine control module to accommodate slight cooling needs such as those ...
