1 cm wide, 4-5 cm long blower? As in, a blower cooler - a tube with a fan on one end? Wha.. Not sure I get this right :hmm:
What's a "larger style" fan header? 3 pin is the standard, 4 pin is for PWM. Unless you mean 4 pin molex, direct to PSU type of thing?
If you could link me to the seller, I would appreciate it. I have put this on the back burner for now, honestly I think it will require a potentiometer.They sell new on flee bay, and not all are from China..........The 1 I bought came in two days.
