whats the highest output you can draw from a 3pin header?

i want to attach a Delta Black Label to my future MSI KT7 Pro2A, but i don't want to fry the header. i just want to watch the rpm to make sure if it fails my system will shut down. anyone have the specs? thanks

Deltas have been known to burn out headers,but you can still connect the sensor wire and get the power elsewhere.

Dunno about your board, I know the KT7's have 4 watt headers.
I don't think just hooking up the rpm sensor wire will work either.

Totally dependant on the Motherboard. The newer Asus models are also using 4 watt headers...but you don't have one of those, I'd check the manual or email the tech support department.
