Aurora-R7, max cpu fan current?
Question for the Dell techies - What is the maximum current that the Aurora R7 CPU motherboard can supply for the CPU fans (4 pin connector: processor-fan connector (CPU_FAN).
I'm looking at driving two 120 mm fans, current drawn by each is 250 mA (free) air to 340 mA (one side blocked) so will be somewhere in between those values, i.e. to be safe, the connector would need to supply 700 mA.

The liquid cooling radiator fan is the same PP749 Delta / Nidec used for ages, they typically come rated as 1.4Amp - 1.5Amp, we'd expect the fan header to handle fan amperage in that range as max
