Did you find that the pad on the underside of the heatsink made good contact with the mosfets?

yes, put the heatsink on once and then took it off. contact with the thermal pads was great.

I did a cooler swap for my 1070 with the Hybrid. And yes, the stock fans run at full speed all the time. Tried plugging it in a fan header on my mobo and I still couldn't control it. I just swapped them with a Phanteks fan. But I noticed that I have to run those at a pretty high fan speed to match the cooling of the stock fans. At least the trade-off is that I can control the fans so it won't run full speed at idle. 

So mounting the Phnateks was ok to the heatsink? Screws all lined up ok? Would all fans be able to mount to that heatsink?

Yeah, it all lined up perfectly. You have to use the same washers and screws the stock fan used though, so you won't screw it in too deep. This is fine if you're gonna mount the fan towards the outside of your case. I also recommend getting some rubber mounts or grommets, as the radiator for my particular unit vibrates from time to time. 

If your motherboard is out of fan plugs or you just want to add a quieter fan, you can add an inline low noise adapter that will run whichever fan at a quiet speed. Many fans come with them. I use Tt Riing series and I have a bowl full of LND's.

UmmI think we are talking about 2 different things here. 
Are you talking about the rad fan? Or the heatsink fan on the card?

I was under the impression that you can control the fan on the card.  It's the fan on the radiator that runs at full throttle.  Is this not correct?

yeah, you control the fan on the card the stock fan for the watercooler can't be controlled unless you connect it to your board from what I know or get change the fan on the water cooler for a quieter one. It can be unscrewed from the watercooler easy, just make sure if you replace the fan that it's a good fan and not just mostly quiet. I have the pre-built 1080 ftw hybrid, so I guess the kit would be almost 100% to it. You will be so happy down the line because of the common heating issue but with this it never really goes above 50c and sticks around this or bellow when gaming.

I was talking about the radiator fans, not the fan on the card. 

Awesome. Thanks for some good info on this.

the reply i got from EVGA 
 
  We generally recommend keeping the blower fan running at 40% or higher; the radiator fan will run full speed unless connected to a fan controller. If you have any other questions, please let us know.
