Corsair Waterblocks... oof

A TON of people asked me to confirm whether or not the Corsair XG7 Waterblocks actually leak since this is something that was recently discussed in some other forums... so we decided to test this ourselves...

He first discovered the issue with the card installed vertically, and it wasn't squirting like that, it would just drip a little, which is still unacceptable.

[@Teksers]

A little drip, ok but what about if the PSU shroud is with holes like some cases have. It will drip along side the PSU and when it reaches the bottom the fans could pick up the water and pull it inside the PSU. If you like fireworks I'm sure you won't like them inside your PC, it's unacceptable either way.

Based on pictures on Corsair's site, 30-series blocks have added the third screw in the middle

[@S3ANnnnn]

Jay ima be honest with you, i can totally see this happening in a normal use case. maybe not everyone, and certaintly less likely if you're experienced setting up custom loops, but that is not a ton of pressure. that could totally happen to the average person and ruin their components.

[@wasabij]

I'm guilty of reaching around soft tubing to pull a RAM stick or CMOS battery. GPU wiggled when I did, but not much, but I could see that happening just from that.

[@riakata]

@@wasabij Also even one or two unnotticed drips can spell doom if there is even a tiny bit of anything in the water (dye, minerals, addatives, dust) as they can slowely dry up and get stuck under that weakpoint and slowly prop it up with temperature cycling. Then eventually it will leak. So if you build it then test fill it and then make a simple mistake and move the connection just a little bit you can screw yourself in the long run. That shouldn't happen you'd have the break the EK block clean apart before it leaked. The only advice is don't touch the tubing at all ever if you want to keep it in your PC and it hasn't leaked and hope you don't have a power supply right below it (which is typical nowadays)

[@shadercekg]

he's just being gentle with Corsair (bc of sponsor) and, at the same time, not recommending the product by doing this video. I mean, it looks crappy, no one would buy a leaking block

[@blueblade455]

Take it apart like Jay just did and add lightly add some silicone/gasket maker around the o-rings then re-tighten the screws. That should get you by until they come up with a better design.

[@riakata]

@@PikaCantSub Yeah but that risks cracking the arcylic it will keep getting slightly loose as plastics creep a little under temperature cycling and eventually it will just crack if you keep tightning it without tracking how far you have gone.

[@UcDesertEagle]

Today's date: 12/29/2021: I've tried to duplicate this same issue in my new XG 30 Series Waterblock, I own an Asus ROG Strix RTX 3090. I can tell you this version of the GPU waterblock has been redesigned, and the 3rd screw has been implemented (right in the middle) as it should have been since the beginning, and also the same way the EK waterblock has it. I've tried to use the same amount of force (for what we can tell in this video) and I can rest assure this issue did not appear, at least on my WB for my GPU. It is definitely very solid, honestly made me feel even better about using it. I've been assembling PC's for more than 20 years now, and I feel confident of my own test. If you happen to have the tools, which I have access to, grasp and pinch strength test tools, I was able to test it with a force of about 15 Lbs of force, considering that, if you have 1 gallon of liquid cooling inside your cooling loop, this could weigh between 8 and 10 lbs of force, could be a bit more depending on your fluid, but usually this is the average. So at least on my end I have peace of mind of the new design and feel very good about using it.

[@Wheres_my_Dragonator]

You underestimate the amount of force the average joe will put on tubing/fittings in their mini/itx builds to force it to fit.

[@TheMitchBarron]

[@peterderbeste6817]

igors lab, one of the best german techyoutubers, had the exact same problem with the exact same block witout explicitely torking it, in his review of the block 7 months ago. corsair literally told him they would fix it and never did. EDIT: LTT had the same problem with this block too in a normal build, so that product is just crap.

[@Kizzster]

They better revise this or fix it, Hopefully with the RTX 3000 blocks they'll have this issue fixed and I'll buy their GPU block. The block has heft and weight to it but someone how they cheaped out on the plastic terminal housing.. There is a workaround getting an EK block instead and hooking up the RGB to iCue with an adapter cable

[@rubbers3]

Keep in mind research, development, implementation and manufacturing takes A LOT of time. It's not something you can do in a week. Then need to look at what is the main cause (screws not tight enough? parts too thin? too small o-rings? not enough screws? too small contact point? the terminal not wrapping around the block? etc) research new solutions, test them in CAD, manufacture engineering samples, test them IRL in different scenarios and different use cases, test long term durability of the solution based on expected use time (sort of planned obsolescence, but not really), and then make a compromise based on manufacturing difficulty, durability and costs, and then actually switching/tweaking the manufacturing process can be lengthy on a commercial level. Especially since this issue is out there, so doing a good job after a while is better, than making a quick change and have the problem persist/create a new one, giving them more bad publicity. So yeah, 7 months might be long, but in this case it's not out of the ordinary.

[@nomadh4tter]

It's Corsair. Did they even opened the service ticket?

[@Kizzster]

@@rubbers3 Or it's just as simple as not using cheap plastic on the most important thing of a block haha but seriously the problem can be easily fixed if they used stronger plastic I reckon with a slightly thicker o-ring. Just replace the cheap plastic and that one o-ring with a thicker version and it's sorted. As a positive I hope they've learned and execute the RTX 3000 blocks better

[@zeron3699]

@@rubbers3 Or just take references from EK...? There's no excuses here, as Jay has mentioned, they should have used another material just like EK doesn't use cheap plastic.

[@ScytheNoire]

I was concerned about the cheap materials Corsair was using and decided to pay a bit more for EK products. Glad I did. Corsair cut too many corners with their water cooling products.

[@TheCarash]

Their cpu blocks are pretty great tbh. The block and pump/reservoir combo leave a lot to be desired. From far away you can tell that its plastic.

[@LcFan96]

im going to do the same, but honestly atleast in my country, corsair is really closed priced to ek, so it wouldnt do much of a difference

[@chrisstevens7866]

Same here, just did a water loop build and their products are cheap for a reason. Like the pump/res looks cheaper until you factor in the RGB controller and one inlet/outlet so I would need a splitter to do a drain. At that point the EK was a cheaper option anyway and probably better quality.

[@vernacular3289]

I have a Phanteks and an EK GPU waterblock in two machines. (SKU: Phanteks PH-GB2080TiFE & EK-FC2080-RTX-TI-CLASSIC-RGB-NP) They both have been running fine. I even swapped the terminal on the EK block with an EK-FC 90° Rotary Terminal because it's crammed into a small case. Subjectively, the Phanteks block looks as little better IMO. Mine has a nice reflective silver cover. My only complaint is that in the design of the EK-FC classic RGB waterblock they glued a decorative piece of metal over the screws you would need to access to service the block. Very dumb design. I pried it off and removed the glue with goo gone which means the ARGB strip had to come off too. No big deal since that computer case has no window to see the block so the ARGB was irrelevant. EK shouldn't be gluing things over top of the screws though as that's something Apple does. Never bought any Corsair GPU blocks even though I use iCUE for their ram, fans and keyboard. It's useful to have all that stuff consolidated into one piece of bloatware rather than multiple pieces of bloatware. I didn't like the aesthetics of their GPU block design personally.

[@Fender178]

Not only that In one of Linus' videos about Rad stacking they said it wasn't a good idea and then Linus removed of of his rads and his temps went up by 5C. So it seems like it to me that Corsair has alot to learn about Water/Liquid cooling. I would have asked EK about Rad stacking to see what they say about it.

[@datacntrdude]

Sent you a tweet with a pic, but can confirm they DID change the 30xx series blocks. I have personally installed a 3090 FE Corsair block and they not only added center screw position, but also changed it to TWO screws in each of the three positions.

Watch his first video on it too. He found it leaking in his system without yanking on it. Major Hardware is a good channel.

[@blahorgaslisk7763]

It's a bit like the problems ASUS had with their TUF RX 5700 XT where the cooler would sag causing bad contact with the GPU and resulting in high temperatures. In that case it was a combination of the card and cooler design and using conservative force torquing the screws holding the cooler. Corsair has a similar problem with the design of the cooler, the materials used and the torque used on the screws to hold it all together. The design was probably made with a rigid ports bloc in mind, while the ports block was scaled down in dimension and material to meet a price point. The screws are torqued to a safe value that almost guarantees that they won't strip the threads or crack the acrylic, and I wouldn't be surprised if it would have worked fine if the ports block was just slightly sturdier. Now keep in mind that the original video from General Hardware showed that the first water block did leak under relatively normal circumstances. It's been a while since a watched the video myself but as I remember it the loop was built using normal soft tubing, but using a 3D printed tube guide to give it more of a hard loop look. This might have added some slight stress to the port block on the GPU cooler, but if so it wasn't really some crazy amount of force applied, yet it was enough to make it leak. Now the water block he received as a replacement was not tested in a system so it's impossible to say if that too would have leaked under identical circumstances, but what was demonstrated in the second video was that Corsair hadn't made any changes to the design and it could still be susceptible to start leaking if used in the same way. Without further data there is no way to know how loose the manufacturing tolerances are. In this case I'm tempted to throw my hat in with Jay in saying that it probably is a very small risk that these will leak in normal use, at least when new. If it was a common occurrence then there would be a lot more noise made by people having it happen to them. After all if it's one thing Corsair is good at it's selling large volumes. Finally I think it's *not* a non issue. The design is weak, and when there's that small a margin between a working computer and a wet computer it's not to be trivialized.

[@norfolkngood8960]

Funny how Jay didn't mention that bit & also felt a little bit covering his arse & Corsairs maybe 5%. Not outright denying the issue but firstly suggesting it was run out of spec due to no rad & then saying he was reefing on it too hard which Major Hardware clearly wasn't.

[@rustycopperpot]

Jay does seem to defend the Corsair stuff. AV Techy did a video about the A500 air cooler that Jay reviewed kzbin.info/www/bejne/a5PTqWucpNh3jbs

[@blahorgaslisk7763]

Yes, I know, answering my own post. Naughty... I just took a look at the Corsair range of GPU coolers and what I can see they've got at least five models of GPU water blocks, and all of them use the same ports block for the inlet and outlet. Changing the design to use three screws instead of only two would require all of these to be redesigned and retooled, which would be very expensive. If redesigning the ports block to be more rigid, perhaps using a better material, can improve the seal enough it would be much cheaper than a full redesign. It might seem crass, but when you talk about these things every dollar counts. Yes it's a problem that shouldn't have existed. The design should have been corrected before it went into production, but it wasn't and now it's time for damage control. Besides if it can be addressed without a redesign of the water block then it's possible to retrofit any of the water blocks that's already been sold, and at a relatively low cost. There has been some quite vicious comments made about Corsair over this weak design. I'd argue that companies doesn't go out of their way to create bad products as that would cost them in a loss of perceived brand value. But they are new to water cooling so they are likely to make some mistakes. With the generally high prices the water cooling market probably looked very tempting, promising high margins if they could achieve large enough manufacturing volume. I suspect the current situation is a result of over enthusiastic money pinching causing the ports block to be made weaker than it was originally planed, and that it might bite them in the ass. For now I'd suggest anyone looking at buying a water block for their graphics card to look at the other established manufacturers first. If you've already got one from Corsair then keep a close eye at it for now and see if Corsair comes out with some kind of fix. You can of course test putting some force on the ports block on your card and see if it seems likely to develop a leak, but make sure you catch any water that might escape. I feel Corsair has over valued their brand name this time. Currently these GPU water blocks cost just as much as the corresponding blocks from EK where I shop. But the EK blocks seems to be of a higher quality.

[@coladict]

Watching you and other channels make so many systems with custom water loops never told me how expensive it would be. I went on EKWB's site and did the math, and it would cost me about 900 Euro to do water-cool my system.

[@ProjectDv2]

Just remember, when you really tighten into acrylic, it will form stress fractures over time. Really crank down on those screws like you did, and it *will* crack eventually.

[@ed-te1fp]

If you've already built your watercooling loop with the corsair block and successfully leak tested it over 24+ hours, your loop is stable and you're fine. But it's definitely a design flaw and you'll have to be careful when adjusting your loop, and I'd avoid buying it for a new build.

To get max water pressure on the cooler, have the water pump output to th cooler and then a radiator since it will cause restriction and increase pressure. To minimize the pressure have the waterflow the other way

[@alastairjones0]

Anything water cooling related I’d go with EK every time. They know what they’re doing.

[@802Garage]

Given there will likely be some strain from the tubing when installed in many desktops, especially by people who aren't very careful, I'd say there is still some risk. Combine the not so tight factory screws with some tension in the system and then add some time and heat cycling and I can def see it weeping eventually. Overall, like you said they should really improve the design just to be safe. Reducing the O-ring channel depth a bit and adding a third screw would definitely solve. Also, I realize it's not going to be taken in and out a lot, but adding metal threaded inserts for the screws going into the plastic would really add some strength.

[@Celician83]

Honestly, if you already have one, then simply do not stretch your tubes so tight, allow a little extra on the tube length and this will be a non-issue

[@Cerus98]

Joshua Bell - It isn’t a non issue. Watch Majors first video on it.

[@Ughmahedhurtz]

"...add some time and heat cycling..." This, exactly. The "well don't pull so hard on it" is just such a lazy answer. If you are extremely careful to not put *any* load on the tubes, you *might* not have an issue over time. But there's gonna be *some* load on the tubes unless you use some kind of custom setup where that is explicitly taken into account. At that point, it is no longer at the level of robustness you would expect. Especially considering all it takes is one drop of water to fall into the PSU or an electrical connection to cause far more damage than the cost of just using a better EK block.

[@Celician83]

@@Ughmahedhurtz sure, it needs to be addressed, but for now, just allow extra tubing, like whatever you think it needs, add 2mm. Also, tighten those 2 screws and you should be fine til Corsair comes up with a fix

Hard tubing also can add a lot of strain in tight areas, so I think there is quite a risk with this. Kind of lucky i held off.

At my company one of the QA tasks for our power modules is to just start grabbing wires near connectors and pulling on them. If they come out they are replaced. If they stay in they are good. If you assume that if you can break it with no special, tools the customer can. You either place a warning or redesign it.

[@WarriorProphet]

For the noobs out there that grew up with watercooling parts for PCs instead of having to cobble them together from heater cores and fish tank parts, you can fix your block pretty easy as far as your existing setup: Add silicone based RTV sealant along that mating surface and re-torque the screws. It would be helpful if someone who has a torque driver could tell us the torque specs as well for this fix, but it's a pretty easy one, just don't put the sealant on too thick, think of it more likeusing liquid metal amounts of RTV sealant, pre-spread so it doesn't get inside the water channels/block.

I think they should go with a different plastic and thicker o-rings for existing owners. They could send out repair kits to them with those new parts, and that should mitigate the issue. I don't think they need a full recall. This waterblock has been out for more than a year and the issue was just now discovered, so it's clearly not physically impacting a huge number of users.

[@lst141]

Last year after 5 years I updated my i7 2011 cpu. When it unmounted the water block I saw that the copper was tainted with oxidation. It must have been a very small leak because I did not have overheat problems nor I had any stains on the board. Anyway, I informed Corsair and even if by coincidence the warranty on both iao’s had just passed by less than one month, Corsair sent me two full new replacements. I just have to say that Corsair support and attitude in my particular case WAS ABOVE MY EXPECTATION. BRAVO CORSAIR!!!

I noticed a similar issue with my Alphacool acrylic block. During leak testing, when i moved the videocard to mess around with the PCIe riser and put strain on the terminals, it started to leak. As long as i keep the videocard seated, no problem, it has been running for months without a single drop. The alphacool block is basically 2 acrylic plates pushing an O-ring together by screws. If you put lateral force on it, displacing the O-ring a bit, it might start to drip. Tightening the screws (careful to not crack the acrylic plates) did help somewhat. It doesn't mean anything is defective, but it is something to note if you need to do maintenance on your computer.

Jay, as an Engineer, you're missing a critical part of this test. Run the loop while it's hot, and then see if torque from just tubing can cause a leak. This is a cold test. You fill the loop cold, and you run it real-world hot, which creates pressure. I have a feeling the pressure will do more (since it's omnidirectional) than the torque will. I'm sad because I have one of these blocks in my basement, sitting in the packaging for months waiting to go into my rig, and I'm wondering if I should even bother...or just send it back, and go with an EK block now...if I can even send it back. I was planning on running an external reservoir with QDC's, and then removing the reservoir after I bled the loop (similar to an AIO), but I'm now worried about the pressure and what it will do.

The EK uses a big chunky black monolith of a manifold that is next to impossible to bend, the Corsair had a nice cost-saving injection molded part, and the part itself is warping because the flange is thin compared to the leverage the tall part gives you. Given how loose those screws appeared to be, a dribble forming after a bit of thermal cycling, and a bit of deformation in the plastic from a static load by tubing being overly tight, wouldn't be surprising.
