I have installed my VX and 2 x Apache PWM fans, but I'm not sure where should I connect the second PWM fan on my motheboard. I connected the first one into CPU_FAN header, but I get CPU Fan Error! when booting up PC. I went to BIOS and saw that when the 1st fan is on low rpm it gets red in BIOS, so I choose to ignore it and error went away. But I'm not sure where to connect the second one, do I need an adaptor cable to connect both to CPU_FAN header?
At the moment second one (the one in back of cooler) is connect as chasis fan, but it's on 100% (1360 rpm) all the time. I does not bother me that much, as it is still very quiet (BTW those fans are amazing), but I want to have all properly connected bofore putting my case back together.
Temps are unbelivable TBH. I get as low as 7 degreed on idle (avarage about 10-15*) and max I've seen after running Prime95's torture test for 10 min was 41*

Note: my CPU is still on stock speed. Is 7 degrees safe?
