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

Was gonna post this too. Hopefully Corsair can do a silent fix on this and I will finally Hydro X my rig.

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.

Same here. no issues

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

acemaninwa871 02-28-2020 04:55 PM

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.

Fake News... watch him Flexing it from 3.30 on wards. he wanted it to leak.. he made it leak.. EK is his God now!

and for the benefit for those quoting away from this forum.. i am NOT a corsair employee!

Infin1tum 05-22-2020 07:42 AM

Regardless whether it's forced or not, it looks like a weakpoint nevertheless. And since reports have been coming in from different people before that video as it seems in this thread, it should definately be a concern. Corsair equals quality and imho that means if there's a potential flaw then they should at least look into it and not shrug it off as "dude is shilling EK".

just my 2 cents

c-attack 05-22-2020 08:15 AM

“Whether it’s forced or not”?? PSA: if you pick up your entire case by the tubes, it may place undue stress on the water cooling system. This is in the category of things you should not do. What physical pieces of your PC respond well to flex testing? The GPU circuit board? SSDs? Anything? Don’t grab stuff in your case and try to bend it. Bad.

As far as I’m aware, this is the only guy with the problem. I haven’t seen any one else in here actually have this happen and presumably most users follow the above the suggestion of not randomly grabbing onto the edge of their block and trying to separate the terminal from the main block. I don’t know if this guy is legitimate or not, but he spends the first half of the video complaining Corsair sent him a new gpu block and about where they shipped it from. Can you imagine if they had taken the original and driven a plastic spike down the middle and mailed it back? Now that would be video worthy.

that's all most have will have done is look at that video and decided... its instantly created sales for EK.

i have several of these blocks my self.. and indeed have witnessed a lot of people fit them through Discord/Here/Reddit/Facebook.. gotta be honest. not seen a single one leak.

Bottom line.

Force anything with a seal enough and it will leak.

shame y'all are feeding that channel with views now...

here's a theory

his original leak was caused by him flexing it while fitting the 3d printed tube supports he has around his soft tubing. i am calling user error all the way.. and he knows it. hence he fails so miserably at hiding how hard he is forcing that block as he unboxes it.. my thumb doesnt bend that far!. and then when it doesnt leak he picks it up while running and flexes it again.. clearly.. in front of your eyes lol. if you can't see that you must be blind.

and this whole thread is scripted by said youtuber.. Pawns in his game of views we are


and still not a Corsair Employee

HI.
Since my video card is not compatible with hydro x, but if it was appropriate I would prefer corsair hyrdo x again.
but if you look at it objectively it should have been 3 screws.
Compared to its competitors, it is very affordable and you don't have to buy a back cover for a gpu block for example at an extra cost.

you sound very cranky and there is real no reason for it. Hes showing a design flaw so it can be fixed in the future.
