Default XG7 GPU Water Block Design Flaw

Issue:
If the tubing is applying a bit too much force on the manifold (where the ports are at) a leak might develop. Other GPU blocks in the market use 3 screws to hold the manifold whereas the XG7 uses only 2.

Workarounds:
*Try to tighten the screws, they may still be loose.
*Limit unnecessary weight on ports

Youtube Video:
Leak can be seen here:

My Watercool gpu blocks only have 2 screws and they don't leak. I would really check for a damaged O ring first possibly a sharp edge etc. Just because it has only 2 screws does not mean that it will leak.

The leak is occurring at middle of the manifold midway between the two inlets/outlets t the top of the block proper so I doubt the O-rings play a part. I saw a video of this the other day and I believe the problem comes from tubes pulling downward when the card/block is traditionally mounted in a case. Vertical mounting (or mounting in a test bench) doesn't seem to invite the problem described in the video.

Additionally, if you over-tighten the 2 screws, you end up bowing the manifold in the middle and thus greatly increase the risk of a leak. I use EK blocks and they have 3 screws holding down the manifold which is the case for a number of other manufacturers.

This whole thread seems a little "click bait" ish....
More accurately than "XG7 GPU LEAKS..!!!"
I think you could say " XG7 GPU can be broken if installed wrong"

I wouldn't say its delicate but it can be broken pretty easily
all that said - it doesn't leak when installed properly and in working order

I think I might tend to agree here. I now a guy using soft tubing and he has not had a single problem with this. So I agree, installing it wrong will cause a leak. More fear mongering as far as I am concerned. Heck the guy in the video might be paid buy EK to try and discredit Corsair. I think this is probably an extreme thought, but ya never know in todays world. But most certainly installing it wrong is going to break it. That's just kind of a duhh thing.

But the guy in the video is using soft tubing.. Doesn't look like it's installed incorrectly to me. If it's so delicate that putting the typical amount of tension on it that is inherent in running hard tubing that it causes it to leak, then it's definitely a design flaw. The Corsair stuff has decent materials being used, but not where it counts.
