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
Heracleidus posted a topic in Build AdviceHi all, I am about to start my first custom pc build, but I am already a huge fan of Cooler Master, and will include at least 10 Cooler Master components in my build. At the moment, I need some help figuring out how to intelligently control fans that are both PWM and RGB. I'm choosing CM's MC500P Case and will replace the stock case fans with a total of 6 MasterFan Pro 140 Air Flow RGB. The motherboard will be a latest generation Asus, with which I'd like to use Aura Sync for the fan RGB as well as some other LED components such as an LED strip. The mobo has the following relevant headers: 1 x Aura Addressable Strip Header, 1 x Aura RGB Strip Header, 1 x 5-pin EXT_FAN(Extension Fan) connector, 1 x Thermal sensor connector(s), 1 x Front fan, 1 x Rear Fan, and 1 x PUMP Fan. As mentioned, I would like to be able to control all 6 fans such that... (1) The fan speeds are intelligently adjusted according to internal temperatures, (2) The RGB of the fans are synced with Asus Aura, and (3) Also still be able to connect some other RGB components to be synced to Aura as well, such as an RGB strip. Other than that, I don't really care which headers are used (e.g. I would be fine with all 6 fans chained to one or two headers via adapters or controllers). I am willing to use whatever RGB/fan controllers or cable adapters that are necessary. I listed the relevant components here: https://pcpartpicker.com/user/Heracleidus/saved/QrTXHx Thanks in advance!

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?
