Ambiguous Fan Header Info from ASUS

[BonzaiDuck]

Problem statement:

My ASUS P4P800 documentation explains the limits on amperage draw from the three mobo fan-headers like this. Each fan header will handle fans in the 340 to 740 milliamp range. OR -- the total draw from all fans cannot exceed 2.22 Amps.

I see a fan I want to try that can be controlled through the motherboard. But it draws 800 milliamps or 0.80 Amp at 12V DC. If this is the only fan that I will connect to the motherboard, does it exceed the manufacturer's intentions? Will it cause damage if plugged to the mobo?

It sounds like you need to power that fan from the powersupply. Route the rpm signalling wire to the mainboard fan header if you need to monitor the rpm's.

I usually won't connect a fan that maxes at more than .5A to a mobo connector regardless of specs.
