Is it possible Heat could be killing my USB card?

I keep getting the Windows 10 USB disconnected sound then I lose my image in my Rift CV1, almost immediately I can see my Rift is working again on my PC screen and the sound is also coming from my PC, but no matter what I cannot get Elite back on my Rift so I have to shut down Elite, log off Windows 10, log back in and re-load. This happened 4 times in less than 20 minutes yesterday, at very dangerous moments where I nearly lost my very expensive ship each time.

I have turned off all the USB power settings I can find, upgraded the USB software, tried everything I can to try and stop this from happening, the only thing I can think of is that my USB 3, Inatec 4 port card is very very close to the exit fans from my Nvidia 1070, could it be that when the 1070 is running quite hard for VR the heat from it is making the USB card too hot?

I cannot move either easily without buying extenders which could add their own problems and the on board USB 3 are not compatible with the Rift. The Inatec card was the recommended one and works fine, sometimes for days or weeks until Windows starts losing it again, seemingly only during Elite, but I cannot really confirm this as it's pretty much my favourite VR game.

Any ideas? It's currently so bad I have had to stop playing, I cannot trust my PC or Rift or whatever to allow me to play for 10 minutes.

The USB "power saving" features first introduced in 8 are still in 10 - and you cannot change these USB power settings without fiddling with the registry as per the KB.

First, cards can be actually physically broken. You can bend them in half pretty easily if you try, but in general they're actually pretty resilient. Many are effectively water-proof even if not marketed that way. I've sent cards through the laundry, and once I dropped one full of precious baby photos right into hot coffee — no problem! Now, I wouldn't recommend pushing your luck, but if you're careful, this is unlikely. Electrostatic discharge could also damage the electronics, although again most cards are surprisingly well-resistant. (Try to intentionally destroy a card with static and your success rate will be low.) Flash isn't particularly light-sensitive, so airport x-rays aren't a real risk (longer exposure to high-energy x-rays is another story). It's also surprisingly heat-resistant — the plastic housing is probably at more risk than the memory itself.

Different kind of card.[wacky]

It'd be unusual for this sort of USB controller card to be badly affected by heat. Its probably not bothered even over 50-60dgC.

I did have some similar problems a while back, usually my Rift would 'lose' the sensor and then immediately re-find it. Odd, and I had the power settings changed as per the kb referred to above.

It wasn't consistent though; sometimes there would be a disconnect and re-connect sound, but no notification in the Oculus Home window.

Sometimes I'd lose vision in the Rift too and have to bail out into 2D looking at the monitor window and moving the Rift around to see what I was doing to get to a safe spot (one it did it just as I was approaching the slot with a boatload of illegal stuff on board (lol, I bounced off the toaster rack and got a fine but no scan luckily, phew!).
I'd lose vision in the Rift, but the tracking kept working just fine.

However, all my small issues added up over the past few weeks into a probably-dead motherboard (I'm writing this on it now) but any 3D/load on the GPU and it suffers horrendous artifacts.
So like me, it might be worth running memtest, checking all the card seating, RAM etc, especially if you've had the rig a while.

Its still early days yet for the software - there may well be lots of les Oculus (and Valve/HTC) have to deal with regarding USB connections, pushing the cards to get fast tracking data out in time for the rendering in 3D.

Sure you can. In device manager select each usb hub, controller and also the Rift sensor. Select properties of each of these then the power management tab and untick "allow the computer to turn off this device to save power" You don't need to edit registry.
