PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

I am planning to make a two thermistor version of etech's/ particle moth's fan control circuit here using a dual op-amp and using a IRF530 equivalent to the BUZ20.<P>Fan control w/ all the bells and ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

Has anyone tried adding fan temperature control to a model FSP-300-60BP or FSP-350-60BP Sparkle/Fortron by installing missing resistor R15 and thermistor TH2 (both next to the heatsink for the low ...

Here is an example of the built circuit on a small piece of stripboard. The 2p coin gives an indication of size. I have not included the diode D1 in this example. Side view. General layout of ...
