I do find it odd that 2 H150's in a row are DOA. That would make me lean more towards an issue with the system, rather than with the H150s ... simply because that's really defying the odds.

Changing the BIOS settings, for the Pro series coolers, won't have an impact. They don't get any power from the fan header; instead, they only supply a fan tachometer signal so that you don't get a CPU Fan warning at boot time. It also provides a second measure of the pump speed - the fan speed indicated will be the same as the pump speed.

The pump does not need any initial setup in Windows; it does have default settings stored in the flash for the pump controller that will be sufficient for the vast majority of installations (even if not ideal or optimized ... sufficient).

The fan situation is quite interesting as well. A 3 pin, DC-controlled fan spins (which means it's getting at least 7V from the fan header) but two different 4-pin, PWM-controlled fans do not. This would indicate that they are either not getting any power, not getting enough power or are getting 0 for a PWM signal. My guess (without testing with a multi-meter) would be that it's getting the 12V (indicating that your power is good) and sending 0 for the PWM signal. However, it's also possible that your 5V and ground power line are crossed, which would wind up supplying 7V on the 12V rail.

But, again, the odds of this happening with two coolers are pretty slim. I would, very honestly, lean towards looking at the power leads to ensure that it's getting the full 12V where it's supposed to be getting the full 12V. I've, personally, found it impossible to directly test the SATA power leads with a multi-meter BUT ... using a SATA-to-Molex adapter does allow you to easily test the 5V and the 12V rails. As the cooler only uses the 12V rail, this would be sufficient to validate that it's getting the correct power. There's also a nifty unit from Thermaltake that will test all of the power delivery rails for an ATX PSU (DR Power II).
