maybe can you try with some 3 pin fans?

Can I run Noctua fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?
You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.
So it may not be possible to be motherboard bios fan speed control with this cooler on some motherboards unless PWM fans?
Then its a manual rheostat or controller as no PWM fans
I did read an online review about the cooler and mentions adaptors for noise quietning and different air flows
Somebody using the cooler may chime in.Edited by Tyreman - 12/8/11 at 3:06am
