Trying to figure out how I'm going to rebuild my system with these new GPU cards.. the AiO Hybrid 240mm radiator is going to be difficult to add in my relatively small case when I already have a 280mm rad on the roof for the CPU. I can either buy a bigger case, which I'd prefer not to because of space limitations, or go full custom loop in this existing 680X case with a 360 rad up the front... but will that be enough to cool these monsters (specifically the 3090) and an i9-9900k as well? Maybe too soon to ask until we see the things in the wild, but what do you think?

Re: Single 360 radiator enough for an i9-9900k + RTX 3090 GPU?

I would suggest another case if the 240 is being used to take the 3000 series cards. Not to mention the 9900k already runs relatively warm as is.

You need to dissipate the heat from a GPU that has 350W of power consumption. That and your CPU will need at least a 360mm. I do not think a 240mm would handle that well. A new case will also allow you to find one with good air flow both for intake and exhaust. The 680x has good intake, but the exhaust leaves much to be desired. How many other fans you got in it?

If you are going custom water cooling, you can remove that 240mm AIO from the top; and then you would have space for 360mm radiator up front plus 240mm radiator up top, all part of the same custom loop. That should be plenty for quite respectable results.

The case right now has 3 x 120mm intake, with 2 x 140mm and 1 x 120mm exhaust. The CPU radiator is 280mm and although the i9-9900k runs warm, it handles ok - even under full load for extended periods it never comes anywhere close to tjmax. I have a couple of very good fans on it too (beQuiet! SilentWings3 140mm PWM high-speed high-pressure fans). The cooler is the EVGA CLC280. The case is set up with the default 3 x Corsair LL120 fans in the front (intake), the 2 x 140mm fans exhausting out through the roof radiator, and another 120mm high speed fan going through a 120mm radiator on the rear exhaust (2080Ti Hybrid). No heat comes back into the case so it is a good setup as is, but the 3080/3090 cards are apparently going to run significantly hotter, so a 120mm isn't going to cut it for the GPU (and the hybrid cards are all 240mm, and 280mm for the KP I believe). Depending on the GPU length, I *may* be able to mount the 240mm GPU radiator on the front intake fans and mount the GPU itself 'sideways' with a riser cable.. although that is then bringing heat into the case which would exhaust through the CPU radiator which is not ideal.. Oh here we go - a photo of the current setup - 280mm radiator at top (CPU), 120mm radiator at rear (GPU), 3 x 120mm fans at the front:

It's a 280mm AiO up top, but yup what you said is another option, I think it can be done in the 680X case but it's a very tight fit.. I've run custom loops in the past (both CPU and GPU in SLI in a big spacious Mountain Mods case), but the maintenance is a bit of a pita - my life is a lot busier now than when I used to build water loops, which is why the AiO hybrids appeal to me so much. If I went custom loop, I'd be doing both the CPU and GPU - no point doing it half-assed. ;)

Here's a video of a 680X with CPU & GPU on a single custom loop, and a fat 360mm radiator at the front. Whether that would be enough to adequately cool an i9-9900K and a 3090 GPU is the question. Also will depend on the length of the new hydro copper GPU - not a lot of wiggle room there. Nice build though!

Yup, exact dilemma I am having. I can either change the case and go Lian Li O11 or just find a way with the current case.
What would happen if I keep my 240mm. AIO as top exhaust, then put 240mm. Hybrid AIO on front (lower or upper section) and set the GPU up vertically? With that way maybe I would avoid pushing all that hot air to the GPU directly, while sucking fresh air from bottom and 1 available front fan. Keep rear and top exhaust for hot air removal. If it's not enough, maybe set the lower fans as exhaust as well to push all that hot air out quickly.
Choices and first world problems.

That's what I'm thinking too, mainly because I much prefer the lack of maintenance required with AiO coolers. The GPU radiator would have to go on the lower 2 fans for my rig - the 280mm CPU rad at top doesn't leave enough room to put the GPU rad on the upper front 2 fans. The GPU radiator could easily sit on the bottom of the case, but it's a bad idea to have the GPU water block at a higher level than the radiator like that, it's just asking for trouble. Wonder if the heat coming in from the front GPU radiator is going to significantly impact the upper CPU radiator though... sigh.. and will it even fit, even with the GPU mounted sideways with a riser cable. The 680X isn't exactly a cheap case though, would be a bummer to have to ditch it. Totally first world problems.  Here's a custom loop build with a thin looking 360mm radiator at front and a 240mm at top, but hellishly packed in.. maintenance would suck.

I mean I am totally against going custom loop just because of the maintenance. I cannot keep up with that, and being in constant worry would wear me personally, I am that kind of OCD.
I remember asking custom loop question in Corsair's own forums and HydroX specialist specifically said that I could vertically mount my GPU while still having the radiator and the pump on front chamber. So I am %99 sure that we can mount that 240mm. AIO on top and still have enough clearance for the vertical GPU. Of course we need to assess the temperatures under stress to find the best place for AIO, which in your case is on the lower 2 fans. I can rotate my 240mm. AIO so that the reservoir or the protrusion is on the other side so that I could fit 240mm. Hybrid Kit on top 2 fans. With that way the radiator would stay higher than GPU block.
Since your's is 280mm. AIO, only solution is of course would be lower 2 fans and that would make the radiator below GPU block. Solutions for you are going custom loop, changing 280mm. AIO to 240mm. AIO for CPU or changing the case I think. None of them are easy but most certainly much much easier and cheaper than going custom loop.
I can't think of anything else for our case sadly.

Yup, 100% agree with everything you wrote, and I'm the same way with custom loops - do not have the time for it these days. Perhaps switch to 240mm for the CPU would be the cheapest option for me, I can just up the fan speed curve a little to compensate. Thanks for the comments, helps clarify things in my mind. Just as long as the new cards aren't too big...

Go custom and fill in all the intake spots with a 360mm front and a 240mm top. Rads might have to be up to 30mm thick + 25mm fans but the new 3090 might get in the way so measurements will need to be done or that might put the breaks on this whole case, dependent how long the 3090.
Or you can stick with a hybrid GPU, keeping the CPU AIO and be done with it that way, again presuming everything fits.

FYI, I just realized the LL120 fans that come with the 680X case don't have very good static pressure (only 1.61 mm/H2O) so they'd have to be replaced as well - they are fine as case fans, but not so much as radiator fans. Corsair don't make a high pressure fan with the dual light loop, so if you're into that bling, it's going to be compromised to some extent. Their highest pressure RGB fan is the HD120 @ 2.25mm/H2O. I have some bequiet! SilentWings3 BL070 fans which I'd probably use instead - 120mm, 3.37mm/H2O pressure, 28.6dB(A) max noise level, PWM fans - no RGB.

Get the exact GPU measurements and work from there. You need to measure the gap between the gpu and the rad you will be putting up front. I wont be surprised EVGA will come up with a hybrid SC2 version of the 3090. Heck, send Jacob a pm and ask him if they will have one and what type of rad EVGA will be using.
T hose who abuse power, are nothing but scumbags! The challenge of power is how to use it and not abuse it. The abuse of power that seems to create the most unhappiness is when a person uses personal power to get ahead without regards to the welfare of others, people are obsessed with it. You can take a nice person and turn them into a slob, into an insane being, craving power, destroying anything that stands in their way. Affiliate Code: 3T15O1S07G

Yeah it's going to be very close.. I believe Jacob said they are using 240mm rads on all the 30xx series hybrids except the K|ngP|n, which will be 280mm. It will probably be the same radiator they use for the CLC240, but I'll have to wait until they post it on the website to know for sure. If the GPU length is ~same as the 2080Ti hybrid then it will fit. Big "if" though.

Custom loops do not have to be high maintenance... don't use dyes or coolants and then there is nothing to break down in the loop. Use a reservoir + biocide + distilled water and you can build loops you won't have to crack open for two years. I use a pond algaecide as the stuff is so concentrated a single capful keeps the loop clean for two years. As for what the 680X is capable of, here's Corsair's chart:  There's clearly multiple options here including the bottom of the case. A single 360 rad by itself wouldn't be enough, things would run on the warm side. A 360+280 would be much better, and you apparently have the option for a second 280mm rad should you want it. It' unfortunate the front intake only uses 120mm fans, 140mm radiators have a lot more surface area...
 Have water, will cool.

Yeah my last custom loop was distilled water & silver coil only, I should have added biocide. I'd never put a radiator at the bottom of the case, that's just asking for issues with any air bubbles having nowhere else to go but into the water block for an AiO. The depth of the 680X case (front to back) is very shallow, which is the problem. The 280mm rad I currently have at the top does not leave room for a 360 or even a 280 rad at the front as they didn't center the 280 option, it sits high just like that image shows. A 280 at the top will only allow a 240 at the front, and only if mounted on the lower 2 fans, and even that may not fit depending on the size of these new cards (even if it's mounted vertically with a riser cable). As I mentioned earlier I think, a 240 at the top and 240 at front (AiO) should work.. and that might be what I have to do, but I'm concerned how a 240 will handle the i9-9900k compared to the 280 I have now... the surface area is I believe about 30% less, and the i9-9900k is known for running pretty warm. Still a little tempted to go for a custom loop, but I'm still going to have the same radiator issues, plus needing to squeeze a res & pump in there as well... My mountain Mods case was amazing for water loops, I miss that big 18" cube, but just don't have the space for it (NYC - space is always a premium here).

Still undecided... so I tried an online " decision maker" to decide between AiO or custom loop. - It came back 3 times in a row with custom loop.  Also saw this 680X build with a 360 at front, 240 at top, and the res/pump in the 'rear' compartment.. interesting. The radiators are thin 30mm ones.. turns out those Corsair radiators are actually HardwareLabs Black Ice Nemesis GTS radiators... nice.

Yeah my last custom loop was distilled water & silver coil only, I should have added biocide.
Please don't do the silver kill coil thing. That fell out of approval, hard. At least one shop went bust over the whole corrosion fiasco which resulted from that trend (Petra's Tech Shop got hit hard for recommending silver kill coils plus PT Nuke). A kill coil IS a biocide; that's not the problem with silver and distilled water. Adding biocide on top of the silver kill coil REALLY escalated the corrosion issues; so it is probably a blessing that you didn't add biocide. Just buy a reputable coolant and you should be fine for years. You can mix your own, but it is risky. If you buy it from a reputable manufacturer, you can be confident that their recipe is approved by a chemist, is scientifically valid, that they have already done the required testing, and that you will have very minimal risk. If you do it yourself, risk. A good coolant should have water, antifreeze, antioxidant/anticorrosion additives, and additives which prevent bio/algae growth. Distilled water on its own is not sufficient. Distilled water plus silver kill coil handles the coolant and biocide needs, but doesn't have antioxidant or anticorrosive properties to prevent corrosion (and actually increases the chances of corrosion due to galvanic reaction). I've been using this for years. I haven't changed my coolant, except for when I had to for hardware changes, and I have had zero noticeable gunk buildup, growth, corrosion, particles, ... nothing. A really good result. https://www.amazon.com/Koolance-LIQ-702BU-B-Liquid-Coolant-High-Performance/dp/B004WSBQTU It is cheaper direct from Koolance's website. You don't have to use that coolant. But please use some coolant. Trust me. Like you, I did the distilled water thing. And I had issues. Probably the same issues you had (you elude to the notion that you had issues). Fortunately for me, my radiators and blocks weren't ruined because I detected the issue in time. There's no reason to try to do it yourself and potentially fail. In the grand scheme of things, the price of coolant is pretty low.

Please don't do the silver kill coil thing. That fell out of approval, hard. At least one shop went bust over the whole corrosion fiasco which resulted from that trend (Petra's Tech Shop got hit hard for recommending silver kill coils plus PT Nuke). A kill coil IS a biocide; that's not the problem with silver and distilled water. Adding biocide on top of the silver kill coil REALLY escalated the corrosion issues; so it is probably a blessing that you didn't add biocide.
I guess I was lucky then! That particular loop I used only the Bitspower .999 silver-plated compression fittings and all-copper radiators and water blocks specifically to avoid corrosion issues, so in that case I had it covered, at least for the silver coil. Any aluminum in there would certainly have caused problems. ty_ger07
Just buy a reputable coolant and you should be fine for years. You can mix your own, but it is risky. If you buy it from a reputable manufacturer, you can be confident that their recipe is approved by a chemist, is scientifically valid, that they have already done the required testing, and that you will have very minimal risk. If you do it yourself, risk.
A good coolant should have water, antifreeze, antioxidant/anticorrosion additives, and additives which prevent bio/algae growth. Distilled water on its own is not sufficient. Distilled water plus silver kill coil handles the coolant and biocide needs, but doesn't have antioxidant or anticorrosive properties to prevent corrosion (and actually increases the chances of corrosion due to galvanic reaction).

Thanks for the links and pointers, much appreciated. I didn't have any corrosion issues in the build mentioned above, but after a while the water started to get a very slight bit cloudy which indicated there was some sort of bio material in the water despite it being distilled and all the silver there.

Personally I'm against silver coils.... it's adding more (+ a different) metal to the loop, and after it dissolves it's still floating around reacting. As long as metals aren't being mixed you don't need anti-corrosion additives... nickel and copper are generally a safe pairing. But even the small details like barbs and fittings need to be matched.
I understand about the space constraints. Some watercooling radiators are designed to mount external to the case, and others like the Alphacool Eiswand, or the NexXxos, or even the MO-RA3 simply stand externally. My very DIY first cooling loop was a 360 rad that mounted off the back of any tower case, something made by Koolance. Either way it's another option at least.
Have water, will cool.

I stopped using distilled and silver kill coils a few years ago after a long run on it. Sure they were nice and cheap but why spend a ton on a loop and cheap out on quality liquids and have to deal with oxidized copper blocks? Done the whole cleanup with a toothbrush and ketchup but didn't want to deal with it no more on a almost annual basis. I says the heck with it and went with Aquacomputer's own clear Ultra Double Protect fluid. Just a annual drain and refill, it's that simple now. Everything has been great since.
Also, if you ever upgrade, I recommend sticking with 120mm sized rads since 120mm rad fans outperform the 140mm. They are quieter and have more pressure while the 140mm outperforms in the CFM department as they are best used as case fans if one needs a 140mm in their life. Other than that, if you're happy with 140mm than that's all that matters.

I'm leaning towards a custom loop now, despite the work involved.. damn this build is going to get expensive! A Corsair 360mm thin (30mm) radiator at the front and a 240mm thin radiator at the top will *just* fit apparently - see photo below. Those Corsair 30mm thin radiators are actually HardwareLabs Black Ice Nemesis GTS radiators, which is noice! The res/pump will have to go in the other chamber where it's basically hidden.
🤔 You can attach the radiator to the fans bracket and have top and bottom fans pushing or pull leaving the middle of the radiator fan-less so there is space for the GPU😼.
T hose who abuse power, are nothing but scumbags! The challenge of power is how to use it and not abuse it. The abuse of power that seems to create the most unhappiness is when a person uses personal power to get ahead without regards to the welfare of others, people are obsessed with it. You can take a nice person and turn them into a slob, into an insane being, craving power, destroying anything that stands in their way. Affiliate Code: 3T15O1S07G

Nickel plating and copper and brass are ok together, right? As long as there's no aluminum in there.

Yes, as long as you're not introducing a silver kill coil or silver/copper based biocide to the loop. EK has warned about using silver with their nickel plating blocks since it was would to create issues. The nickel plating started flaking off the block for some. Mind you this was almost 10 years ago. Also for warranty reasons, say you were to build a all Corsair loop which I think isn't a bad idea because I feel their lineup is actually nice especially knowing their rads are Black Ice, I would stick with a clear fluid from Corsair. Just use either the tubing and or RGB LEDs for coloring via iCue. I'm sure you could build a massive ecosystem with liquid cooling, monitoring and controlling via iCue.

Yeah I've been looking at the Corsair Hydro X gear so I'd go with their fluid as well, but probably a different CPU block, possibly Optimus. I planned out a loop with a 360 and a 240 radiator in series.. with all the fittings etc it comes up to around $800.  ..that's a lot of cash just for cooling, and that's not including the GPU block (I'm assuming I'll get an EVGA Hydro Copper). Sure makes the AiO GPU more attractive lol.
