I would like to use the MasterLiquid Pro 280 paired with an ATX power supply and a PWM fan controller in a cooling application without a PC motherboard. However, I cannot find a 4-pin PWM fan controller; I've only found 3-pin controllers (some of which claim to use PWM over the 3-wire connections). If I use a 3-wire PWM controller with the 4-wire MasterLiquid Pro 280, will I damage the control circuitry on the pump or fans? If I use a 3-wire voltage-varying controller with the MasterLiquid Pro 280, will it damage the pump or fans? If so, could you recommend a fan/pump controller for me to use? Thank you, Adam J.
I have recently bought two MasterFan Pros and both are connected to my motherboard PWM headers. As far as I can tell from CoolerMaster's specifications and marketing material, the profile switch on the back of the fans simply limits the max RPM the fans can go up to. It's probably meant to be used when the fans are connected to the power supply via molex. So my question is, should I set the profile switch to performance mode and let the motherboard handle the RPM instead of manually limiting it with the switch? With PWM, under the same conditions (ambient temperature, CPU load... etc) wouldn't the RPM/noise be the same at all three profile switch settings?
Hi I am new to this community and I don't know if this is correct place to ask. My Masterkeys pro M (white leds) kb backlight flicker. Frequency is 150Hz to be precise. This is damn too low. Measured with oscilloscope and light sensitive diode. MAX backlight: MID backlight: MIN backlight: From this review is evident, there is one 16 channel PWM driver to handle all keys backlight. The only way to achieve it is by multiplexing it between different groups of LEDs. When LED is off, other groups are served. So main PWM is running around 4kHz, but multiplexing on 150Hz. I understand this limitation, but multiplexing is not necessary when whole kb is backlit with same intensity. I would be really grateful if CM can modify FW to not mux in "all keys backlit" mode. Faster muxing would fix it too, but IDK if PWM driver can handle such quick changes. There is HW mod way too, but when FW can fix it.... FW mod like spite did would be possible too, but I believe CM can handle this. Any ideas? Opinions? xorly
