I just got a couple of Antec Tricool fans. One is a 120mm with a 3-speed
switch, the other is an 80mm with no speed switch. Unfortunately, the
packaging contains no documentation. Anyone familiar with these?
Both of these have a lead for sensor pins on the mobo.
My mobo only has 1 such set of pins marked "case fan" that I've found, so I
currently have the 120mm fan connected to it. What's not clear to me is how
the speed switch and control socket interact. Does the 3-speed switch
override the mobo speed control or will the fan speed change within a range
at any of the speed settings?
What's the difference between how the the 80mm fan (no speed switch) will
behave depending on whether it's connected or unconnected to the sensor pins
on the mobo?
Thanks
If the fan has a switch on it, then that will control its maximum
speed. My 120mm fan is set to "high" and I let the power supply
control its speed (my power supply has special fan power cords.) If
this switch is set to "low" then that will limit the speed (and noise)
of the fan. Look at your MoBo manual to find out about the speed
sensors. You may have CMOS settings to set/enable them.
