CPU fan's wire function (3-wires type)
I've just bought a new fan with heat-sink
for pentium MMX on second-hand
mainboard form local computer store.
It is 3-wire type. (red, black and yellow)
Unfortunately, there is no 3-pin connectors on the M/B, but, I still have 4-pin power connectors form chassis
fan avialable for this CPU fan. So, I need
to know the 3-wire's function.
Anybody can tell me what is the function
of each 3 wire? I guess one of them is
power, an another one is ground, and
the last is fan speed signal line, but
which one is the signal? The yellow?
