Methods and devices to employ air cooled computers in liquid immersion cooling
The present disclosure refers to methods of employing a computer comprising a pulse width modulated controlled cooling fan in an immersion cooling process. The present disclosure also refers to devices therefore. Such methods and devices employ a direct conversion or a probabilistic approach to emulate the operation of a pulse width modulated controlled cooling fan. The aforementioned methods and devices may be particularly useful for fans having a fan speed of 25,000 rpm or higher.
1. A method of employing a computer comprising a pulse width modulated controlled cooling fan in an immersion cooling process, wherein the method comprises:
converting a pulse width modulated controlled fan signal to one or more analog signals;
feeding said one or more analog control signals to a voltage controlled oscillator which is configured to transmit one or more signals to a processor at a frequency that confirms to the processor that the pulse width modulated controlled cooling fan is operable.
2. A method of employing a computer comprising a pulse width modulated controlled cooling fan with a motor in an immersion cooling process, wherein the method comprises:
employing a timing element to output a signal at a maximum frequency of the motor;
mixing the signal with an input to a pulse width modulated controller of the cooling fan and an AND gate in a manner that approximates a reduction in frequency to confirm to a processor that the pulse width modulated controlled cooling fan is operable.
3. The method of claim 1 wherein the pulse width modulated controlled cooling fan has a fan speed of 25,000 rpm or higher.
4. The method of claim 2 wherein the pulse width modulated controlled cooling fan has a fan speed of 25,000 rpm or higher.
