Based on what you said I should be able to power the H20 920 pump and its two fans from the CPU_FAN port without worrying about the pump changing speed, but I'm worried it may get too close to the 1A, 12W limit.
I might still be better off letting the pump's USB software control those two fans and connect it to the PSU directly. If I went that route and left the CPU_FAN port empty, its just change a setting in the bios? Nothing else to worry about? And on the other hand keeping the pump on the CPU_FAN line means if the pump dies I'll get some warning about it.
Yeah a fan controller would solve the problem but I'd like to take advantage of the Fan Xpert 2 software that grambo wants to use as well.
Speaking of Fan Xpert 2 that kind of sucks if it really can only use the CPU temp for fan control. The z77-v pro and deluxe have other sensors on the motherboard right? If the Sabertooth has it, they should have been able to mix temps too.

If each header can supply 12W/1A I'm not too concerned about running 2x 120mm low speed fans off a header, as they tend to draw below 2W each (here's one that draws 1.25W that I would assume is typical load for a 1200-1500rpm fan http://www.directron.com/4412fgl.html).
What does the 920 pump need? If I were you I'd probably play it same and run it off the USB, since you will want to be able to control it to reduce noise? I've never used water cooling so I'm not sure how that works (pump speed/noise).
There should be a setting in the BIOS to disable the CPU fan warning, I haven't used it yet myself as I haven't switched my CPU fans over to a MB header yet... been procrastinating since I'll almost for sure have to take the heatsink off to get at the CPU fan headers in my case and it's a pain in the ass.
It does suck about Fan Xpert 2 only using the CPU temp (the MB's CPU temp sensor, not the actual core temps inside the package), I believe Asus is using the "Thermal Armor" feature of Sabertooth for market differentiation from the Pro/Deluxe boards. It would be purely software though, as the temp sensors exist on the Pro/Deluxe (not as many as ST but there are a few).
