Has anyone actually found a way to slap an AIO onto a 3080 yet? I've got ideas for a SFF build, but it'd be much better if I could go dual AIOs than dealing with open-air cooling.

seems like a 3070 should fit in it, right? maybe the reason it's not already sold out is that the 650W PSU is underpowered for the 3080 and the space concern, and everyone's all hyped on 3080s rn. or maybe people have moved on from the H1, or no one noticed that it's in stock and it'll be sold out 15 minutes from me making this post

Many 3070's should fit, yeah. Hell, many 3080's fit, and even some 3090's: compatibility matrix

650W is just fine for a 3080 as long as you're not planning on trying to overclock it to the MAXXX and pair it with a 10900k you're also planning on clocking to the moon. For a 3070 it's borderline overkill.

I'm still kinda dubious of the FE style in sandwich cases tbh. I'd rather go for an AIB if I were going for case like that.

You can't. The FE is the only card that's strictly sticking with the two-slot height limit. You might be able to wedge a ASUS TUF or EVGA XC3 in there, as they're only slightly taller, but any other AIB is far too big for that case.

It's a 3-slot case.

Hence the 3090 that fit in there. IDK what 3090 AIBs are like size wise but I should have clarified that I was talking about the 3080 in my post, my b.

It's a modifiable case--you either get a 2-slot GPU side and reasonable space for a CPU cooler, or a 3-slot GPU side and miniscule space for a CPU cooler. If you want to stay with the 2-slot GPU setup, your 3080 options are quite limited--FE, TUF, XC3. If you do the 3-slot setup, then yeah, you can fit some other cards in there.

It looks like a lot of the 3090 AIBs aren't much different in size from the FE, and in fact some of them are actually thinner, so they'd fit even better. Obvious exceptions for fatty thiccs like the effectively 4-slot Auros cards, of course.

But yeah, I think you're right that if you're gonna do a 3080 in the 3-slot configuration, you'd be better off with one of the AIBs with more aggressive cooling capacity.

Specifically a 3080 or 3090 - the 3070 is supposedly going to draw much less power (somewhere in the 230w range) and should be more than fine with ~600w.

As long as you're not trying to run an Intel chip OC'ed to the moon, plenty of people are running 3080's on a 600W PSU without issue. You can't really overclock them meaningfully, anyhow. In fact, a bunch of people have been able to undervolt and shave up to 50W off the things with only low single-digit performance loss, which is hilarious. If you're going AMD, overclocking their CPUs is basically a pointless exercise, too.

I mean, all things being equal, sure, a 750W unit over a 650W makes sense. But if your choice is 650W or nothing, or the price delta is considerable, a 650W is unlikely to actually limit you.

Also not sure what the market in the UK looks like, but in the US Seasonic has a SFF 650 for basically the same price as the EVGA one, and Seasonic has a 10 year warranty, which you simply can't beat.

The Phanteks Enthoo EVOLV SHIFT might also suit your needs. The profile is eye catching, and it has tempered glass if that's your thing. IIRC you need to give some thought to cooling though unless you're going full custom loop (but that's the price you pay for tempered glass).

I am trying to build in this case now (pending parts). Finding this case is a pain in the rear end right now, to the point where I ended up having to buy it on eBay. It's beautiful, though, I'll give it that much.

That said, it looks like it can only support an ever so slightly thicker than 2-slot GPU (like, maybe 5mm larger). Width and length are no issues, though.

Apparently temps are much improved if you're willing to take the front and/or rear panels to a local CNC shop and have them mill vent holes in them.

They are harder to find, yeah. I'd go through Amazon, so at least you're still backed by a real return policy.

ATX brackets are pretty much fine. If you're going to 3d print it, just up the fill reasonably high, or buy one from someone. As long as you're not putting the thing on an earthquake plate or something, it's not like it needs to be able to withstand all that much shock or anything, and if it's getting hot enough in there to melt/deform the plastic, it's way too hot in there.

Related, if you don't have it yet, you can use CamelCamelCamel on Amazon as a historical price tracker to see how badly you're getting gouged.

600 is more than enough for a 3070 (~230W) unless you want to run an Intel 10th gen chip wildly overclocked. A Ryzen 3700X + 3070 + 16GB RAM + 1x NVMe SSD on a normal motherboard should be <500W, probably closer to 450W peak.

SFF people, how do you handle multiple fans on an ITX board? The X570-I from ASUS has 3 headers (CPU, Pump, Chassis). I'm gonna go google this but is there anything BIOS related that might affect the pump header like having it run at 100% RPM, or is it just labeling and they're all the same. My next build is probably going to have 4-6 fans depending on space constraints, two on the heatsink, and two intake at a minimum. If I can, an extra 1-2 as exhaust fans.

Depends on whether you're doing an AIO or not. The "pump" header is normally just a standard fan controller that is rated for higher amperage to support the extra power draw of a pump, but otherwise should function just fine for fans. Actual speeds should be controllable in software.

If you're running them in pairs like it sounds like you are, you could get splitters and run the two CPU heatsink fans off the CPU header, the two intakes off the pump/chassis (whichever's closer), and the two exhaust ones off whichever is left over.

Other options are to use a dedicated fan controller, or go with something fancy like Arctic's PWM PST fans that let you daisy-chain them.

If you're doing an AIO, then you should be using the pump header for the pump, but otherwise can then do much the same: two intake fans of one of the remaining headers, two exhaust fans off the remaining one.

Shorter lifespan, more failure points, more catastrophic failure modes, potentially pump noise. Cheapest good aio (arctic freezer ii 280) is like $100 vs $60 for the fuma 2.

Most AIOs from reputable companies last 5+ years, but I suppose it's true that you can't just leave them on there forever. Pump noise is hit or miss, but I've never had an issue with one as long as I had it installed right and put a little effort into making sure I got any bubbles out of the pump itself. Can't really say much about catastrophic failures--it's a potential risk, albeit not one that's likely to occur. Corsair, NZXT, and EVGA have been known to cover parts destroyed by leaks, but I don't think they actually have that policy in writing. Personally, I have a cheap (like $1/mo?) rider on my homeowners insurance for computer coverage, so it's not a real concern of mine in the first place, but obviously that doesn't apply to everyone.

You really don't need a 280 AIO for a CPU though, especially an AMD one with a mild overclock. There's often only a 1-3C difference in performance between a 120 and a 280 until you start getting crazy, like pushing 300W through a 10900k. An H60 is ~$80 and performs very well and should fit well in those cases.

If you aren't going 280 why go aio at all? An H60 is probably gonna straight up get beaten by the tower coolers (context of the conversation is the nr200 which can fit the fuma 2 and the u12a).

I haven't seen a direct comparison, but a H60 is usually +/- 1-2C from a NH-D15, so you can work your assessment from there.

The "why" is space. The guy literally said the U12A didn't fit with the NR200P with his setup. But yeah, if you can fit a nice air cooler it's not like you're going to get noticeably better performance out of an AIO--and that applies to the 280's, as well. They're total overkill for a ~150W CPU.

Now if you want to talk custom loop, then a 280 makes a lot of sense if you're wiring both the CPU and GPU into it.

+/- a few degrees doesn't mean much absent noise. If you noise normalize it gets dumpstered by big air coolers.

At low temps, you're right, since the H60 is a constant-speed pump and therefore will generally be louder at "idle" than a good air cooler. At load it evens out to pretty similar, though. I finally found a direct comparison: https://techbuyersguru.com/corsair-hydro-h60-2018-cpu-cooler-review?page=3

But yeah, if you're looking for a "silent" PC, a constant-speed pump like the H60 ain't the way to go. Either you want the Fuma if you spend most of your time at idle / low load, the U12S if you spend most of your time at higher load, or a Kraken X41 since it's variable speed (but those are also >$100 so the value proposition is poor).

Basically if you can get away with an air cooler, you might as well do so. But if you can't physically fit it, there are viable AIO options that will do quite well.

Of course the real answer is to drink the funny-colored koolaid and go full custom loop and try really hard not to think about how you just spent more for pipes and pumps and blocks than you did on most of the rest of the system combined.

When I look at that load chart I see it getting poo poo on by the u12s - 28 db vs 37 dba for 175w load and 33 vs 40 for 200w load at nominally the same temperatures. And the u12s is straight up worse than the u12a.

Yeah, don't get me wrong, if you can fit them there's really no reason to consider anything other than the Fuma/U12. It's when you can't that you gotta start looking elsewhere.

The other use for an AIO is when you want really directed thermal control. For example, I'm trying to figure out a build in a Evolv Shift, which is well known for looking cool as hell and having abysmal thermals because it was designed by someone who apparently never bothered to actually run a system in one. I could toss a Fuma in there, but it would cook itself because the airflow is so poor--so I'm likely to end up either with an AIO or possibly a full loop if I get drunk enough one of these nights with my wallet near my computer, simply so I can redirect the heat out the bottom.

The evolv shift is brutal for thermals especially if you want the glass version. I can definitely see going with 2 120mm aios for that case with one on the gpu (or custom loop with 2 120 rads).

Of course I got the glass version! ~*~aesthetics~*~

I am idly considering doing the CNC mods to the front and rear panels, though, since apparently just drilling some holes in them drops internal case temps by like 15C, which is...not indicative of a well designed case. gently caress, I wish it didn't look so good and I could convince myself to use a much more sensible case. Plus I haven't found a local CNC shop, anyhow.

The best part is that it only sorta supports 2x 120's, in that you have to get thin ones and use thin fans on them. If I go custom loop I might just do one of the double thick (~50mm) 120s, since last I checked there wasn't much performance difference between a double-thick 120 and 2x normal 120's.

That a block for a 3080 is gonna cost ~$170 is an obnoxious price-add, but AFAIK no one's yet released any G12-style AIO adapter for the 3080, since NVidia went and changed the mounting holes for the first time in like a decade. Drunk engineer me wonders how effective zip-ties through the holes would be in holding a AIO block on, though, because dumping 300+W of heat into that case with an air-cooled 3080 doesn't sound like the best plan.

An AIO for SFF to me is better suited for GPUs rather than a CPU unless you're running primarily CPU-bounded tasks like non-GPU accelerated video encoders all dang day. GPU power usage has climbed dramatically for the mid and upper end while for consumer CPUs it's mostly held steady or dropped within their respective user tiers.

Oh yeah, AIOs on GPUs even for non-SFF cases is magical. Better thermal performance, lower noise, and you can actually dump all the heat out of your case instead of hot-boxing everything inside. I've been running them since the 980Ti, and A+ would recommend.

Oh, it's totally doable. Just for $500+ with a custom loop, at which point it looks fantastic. Or you use an AIO-equipped GPU--that all the 3080's are going with 280+ AIOs angers me.

Funny thing is, it's not really a small case to begin with. Frankly what I really want is a Corsair One, but those guys are always a year or so behind with components and don't support TB3, so I'd have to give up 10Gb networking, and that ain't happening.

What's a suggested size for an aio for a gpu in a cramped case like the nr200. Is the general consensus of 120mm rad per component still apply for sffs?

If you've got the space for it, get a 240/280. Not because it'll actually cool much better, but because you get much better options in terms of variable speed pumps (which you want) at only slightly higher costs. If you're just looking for the cheapest, you could do a H60 or similar, but they're constant-speed and thus a bit louder than a lot of people would prefer, given that a SFF is often located closer to you / more obvious than noise in a tower case shoved under a desk would be.

From a pure cooling perspective, a 120mm is more than sufficient for either a GPU or CPU, though as noted up-thread there are generally quieter CPU options available if you can fit them.

Nope, the FE makes an effective price floor: everything else will be more expensive unless you find one of the cheaper cards with a $50 sale or something.

Or just use the fan control software either built into basically every motherboard these days or via Windows to set a fan curve that skips that particular RPM segment, and just jumps from like 900RPM to 1100RPM. Not every P12 exhibits the issue, either. But it's like 10 min of work to save $20/fan.

It's a difference between being effectively silent to "I think maybe I can hear something?" So if it's just there for 1 second as a transient state you're not likely to notice it.

The biggest spike I've seen so far is ~330W, with sustained being down in the ~290W range mostly. So even a 550W PSU would be able to keep up with that without much issue, though for safety I'd probably get a 600 or better.

If the prices are similar, I agree: I'd pay $10 or $20 to bump from a 550W to a 650/750W, sure. But there's been a tendency to drive people to buying these $200+ overbuilt PSUs on the thinking that they need them to power a 3080 + Zen3, when that simply isn't the case. Same with pushing people to get Plat or Titanium rated PSUs, despite the price increases there making no sense whatsoever for 99.99% of people (haven't seen much of that pushing here, but certainly on other forums it's rampant). 2% extra efficiency is never going to pay off the up-front costs, sorry.

Basically a lot of people are being told they "need" a much more expensive PSU than they actually do, based on outdated rules like "don't run it over 60% load" or other nonsense. But yeah, if it's only a couple of bucks more, why not get the bigger one?

If you're searching for a "silent" PSU, a few more watts isn't likely to make that much of a difference, since most of the "zero fan" ones stop running silent at 250-300W, and once the fan kicks on, straight wattage isn't often a good indicator of how loud it will be. You end up having to dig through reviews to find out if a given model bothered to pack a good fan in there, or if it's some loud rickety mess.

But yeah, other than the ease of managing power input (which is legit something to consider when you're strapping it all to your back), as a $400+ board that one struggles to find much reason to exist considering the other much cheaper alternatives already out there.

e; or really need onboard 10GbE in a mITX format, but can't/don't want to use a TB adapter, which is...uh...gonna be a very specialized need. Which, I suppose, is why it's a $400+ board--likely super low volume, so high cost amortization.

So as far as CPUs, the conventional wisdom lately seems to favor AMD for price/performance but does that change at all when trying to consider cooling in a particularly squished SFF case? It seems like I see a lot more intel builds on the SFF reddit, but maybe that's just my random sampling. My usage is gonna be pretty moderate as I'd just stream from my desktop for anything intense. Probably my most intense cpu usage I'd rather do local would be Civ6.

You see a lot of SFF Intel builds because Intel CPUs, up until Zen3, were still notably better for gaming than AMD was, and a ton of SFF builds are made by gamers.

Cooling, if anything, favors Zen3 even more: you get excellent performance at stock / very mild overclocks while staying within very reasonable power profiles. Intel chips right now often need to overclock into the 200W+ range to be competitive. One thing that's true is that there are more SFF-compatible Intel-style coolers than there are AMD, but most of the big-name ones (Noctura, etc) have AM4 mounting brackets, so it's not a big issue. Also some mITX AM4 boards actually use Intel 115x mounts specifically to expand cooler selection, so be sure to check on what you're getting there to make everything match up.

Depending on how much you value FPS on Civ6 and the like, you might want to check out what prices you can find Ryzen 3600/3700's for: a 5600X is a fantastic chip, but at $300 might be a little overkill if all you want to do is light gaming for the most part.

Speaking of AMD CPU's. Hot drat I can't find a 5800x anywhere. I guess the new GPU's aren't the only thing that's hard to come by.

5800X's were always destined to be very hard to get: they require a "perfect" CCX complex to make, vs the 5600/5900X which utilize "imperfect" 6-of-8 core CCX's, and so are enormously easier to make.

I'm guessing this is just covid or is there really an insane surge of people building computers?

Same difference. AMD has limited production capacity, and a ton of people want those chips, for various reasons. They'll be a bit annoying to get for a while, I'd think.

Enjoy jumping the board with a screwdriver.

Real men use knives. Just sayin'. (which they then wave threateningly at the board when it doesn't work right)

Do any of you guys have a 5800X or 5900X to help me activate a game code? Or does anyone actually want Farcry 6? I think my code expires at the end of the year.

Yes to both? If you've got a NVidia account, I could try trading you for CoD: BO CW (jesus gently caress they need shorter names) that I've got spare from buying a 3080.

Makes me wonder how the Corsair One accomplishes putting all its I/O out the back when its GPU is vertical. :thunk:

Small (~6") cables that connect to the outputs of the card and then are routed to the ports exposed on the back of the case. They didn't go with right-angle ones because there was (barely) enough room to just use "normal"-ish cable connections. It worked well for them since you weren't supposed to be mucking with it basically ever.

You can see if the motherboard exposes VRM temps, otherwise do you have a temp gun or sensors you could stick to them? All the wattage for your CPU goes through those, so they could be disappating a considerable amount of heat from shoving 150+W through them--a "good" temp is usually around 60C, with poor implementations hitting 90+.

The X570 chipset is only supposed to draw like 10W, so it needs a lot less cooling.

Anyhow, it's hard to say what will or will not be sufficient, especially since lower fin cross section can be made up for by better airflow (or vice versa), and I have no idea how much air it'll be getting with your setup. Try it and see? Worst that happens is temp skyrocket (have a sensor to be able to see this!) and the whole system throttles because the VRMs start choking off the power so they don't cook themselves.
