ProTapes Pro 950 Polyimide Film Tape

So, I have set up a full custom loop and so far my EK 3.1 DDC Pump has leaked near the outlet and been replace and my EK Supremacy MX water-block has leaked at the base and I have ordered a full nickel Supremacy EVO. Swapping out the CPU water-block resulted in a few drops of water dripping onto my 1080 ti and they went through a couple of holes in the back-plate onto the PCB. Anyone have an opinion about using Polyimide Film Tape to cover the top of the graphics card all the way to the motherboard and wrap around the sides of the card.
This will prevent water from dripping into the card an force it to roll off the side of the card if another leak occurs.

First, does anyone see a problem with doing this? The GPU water-block should be removing the heat and ventilation should not be an issue or am I wrong?

Second, can my graphics card be killed without water getting to it? For example water gets onto the motherboard only, could this kill my 1080ti? If this is the case I may cover the whole board below the radiator. My case has no window so appearance is a non-issue for me. Eventually I am going 2080ti so I am wanting to find a near risk free way to silently cool my system.

Water dripping may damage the GPU, but it may still be fine. I had my CPU waterblock dripping water on the GPU in the top PCIe slot. The slot was soaked wet. Everything is fine though, the GPU and the slot work well after drying them.

I replaced the o-ring in the CPU waterblock, and put some Molykote on it for good measure. Never had leaks in 2-3 years since then.

That I think is a better approach, than wrapping the GPU up in film. Just fix things and do leak test.

Yes, I am not anticipating any leaks and so far nothing has been powered on except the pump, but you never know and if I am putting a $1500 graphics card into my system I want to know it is protected.

That's a lot of leaks. There are some good threads on pressure testing your loop. That might help.

I'm so confused.

Why are you trying to cover leaks with tape when the problem is obviously that the loop isn't built properly? Custom loop components don't just leak by nature. If you have a leak, something is wrong - either the component itself is damaged, a tube is not making proper contact inside a fitting, a fitting is not tight enough, there's an O ring issue, among other things.

You replaced your pump and your CPU block because of leaks and you still have a leak. Did you consider that there was nothing actually wrong with your previous pump or block?

It's frankly silly to be concerned with whether water on your mobo can fry your GPU. That may be a possibility but it's irrelevant. You need to build your loop properly so it isn't leaking.

Is it hard tubes?
