How to configure 2nd private cross-over cabled NIC?

Hi. I have 2 Windows 2012 Server on a LAN 192.168.0.x, 255.255.255.0, 192.168.0.1

I've just added a 10GB Ethernet card to each server and connected them with an Ethernet cable (10G uses straight not cross over cables - built in auto sense). I've assigned server#1 Ethernet 192.168.5.11,255.255.255.0, no gateway and did the second server NIC the same way with 192.168.5.41

The cards report they are each connected at 10GB and now I just need a way to use them to move virtual machines from one server to the other.

I guess I need a static route, but everything I find on the Internet say I need a destination router to make it work.

Please help and tell me the static route line that is needed to make this work. I can change whatever is needed on the 10G NIC settings, but cannot change the LAN settings the other 1GB normal cards are using.

Thank You!

Open a cmd window and run
route print

To what interface is the routing table currently sending traffic with a destination of 192.168.5.0 / 255.255.255.0 ?
(do that on both machines... note that each packet is processed from the bottom of the routing table to the top, and the first rule it matches on the way up determines to what interface the packet is sent.)

I didn't want to tell you the wrong thing, so here's the route print from both servers:
The "Intel(R) Ethernet Converged Network Adapter X540-T2" are the connected NIC ports. They are dual port cards, but I'm only using 1 port on each card at the moment.

I just double checked, the configurations do not have a default gateway or DNS servers. They did to begin with, but I removed them after reading on the Internet they should not have any. I don't know why they still show as having any in the route print.

I rebooted and found one NIC had the old gateway on server #2:
