Hello everyone!
 
I just purchased a 1080Ti FE Hybrid Kit and I'm a bit interested in the connectors and the power draw of the pump/rad fan.
Could I put the pump in a mainboard CPU (PWM) Fan connector where it will get constant 12V, so it doesn't draw off my somewhat limited 300W of the card?
By that I mean:
1st: is the plug on the pump the correct one to plug into the mainboard?
2nd: how high is the pump power draw (will my mainboard be able to feed it with a cpu header)?
          EDIT: I'm thinking about buying a Corsair Commander Pro fan controller so I can control all my other case fans properly too. Power output per connector should still be the same as a cpu header or so, but anyways, would this work too?
3rd: If the shroud fan is controlled by core temp, will it still spin fast enough to properly cool the vrms or will I have to do major changes to the fan curve?
4th: If above ideas work, is it ok warranty wise to do so?
 
Any experience or information is appreciated!

Yes the pump and fan should be drawing from the power limit as the current draw is measured at the +12V inputs (current sense chip monitors the 2x PCIe cables and the PCIe slot).

Pump and fan both have their wattage printed on the stickers. They're about 7.7W together if I remember correctly (pump drawing 7.5W of that).

Both the pump and fan both run at full speed all the time.

The blower fan for the VRM's is controlled by the card. The other stuff; pump/fan steal the +12V from that fan connector.

If you want to connect the pump/fan elsewhere your options are:
• Leave pump connected to card and connect the fan to MB header (IMO pointless as the pump draws most of the power).
• Use a different pump that gets connected to the MB/PS and only grab (I.e. Unscrew) the adapter plate from the one that comes in the EVGA box.
• Make/buy adapter cables to connect the pump/fan to the MB/PS.
• Make a adapter for only the fan that steals the PWM signal from the GPU. -- This will give you software control (30%-100%) of whatever PWM fan you attach. -- Also somewhat pointless, but does have some advantages.
• Desolder the stock cables and solder your own (the pads aren't too small and you can even add a tachometer wire), then connect it to your MB/PS
• Solder stock power input cable directly to the 8pin +12V and GND. -- Risky for the card but then you can tuck the cable inside the shroud. I SERIOUSLY don't recommend this one.
Note: With any of these you can replace the fan too. Keep in mind that the default pump connector is 2-pin (no PWM or Tach.).


Any soldering done to the pump or card will void EVGA's warranty! Anything that doesn't involve soldering or connecting crap the wrong way is fine provided you can return the items to stock condition before doing a RMA.

Yup the pump takes plain old 12V from the GPU fan header and then splits it off to another wire for the included fan.

You sure about the fan drawing 3W? I only have a NF-F12 PWM in front of me so I can't recheck the EVGA fan, but the Noctua one is rated at 12V 0.05A (or 0.6W). Surely other fans draw around the same 1W-ish?

Keep in mind that if you do connect it to the card you can totally increase the power limit to compensate for the extra draw from the pump/fan.
