Well, exciting, although I would love to see some concrete numbers. To be fair, there could be a valid technical reason - it's somewhat unlikely anyone here is an IC engineer enough to reasonably opine, however, what'd be really wicked is the behaviour being poorly undocumented, leaving customers guessing as to what cooling system to opt for (more likely complely oblivious). This could conceivably be done for marketing reasons - you wouldn't want to generally advertise a loss performance at 50 or 60C if you are selling cards that always suffer that loss in practice. Yeah, I'm starting to wonder if if 3090 Ti wouldn't be a better idea (for my purposes). I'm more VRAM bound and there is that NVLink. I can click and buy an FE right now, and if thermals suck - WC it (albeit at an almost certain loss of warranty presumably).

Safe bet. Some youtubers have bragged about being busy testing.

Well, I looked at the link - says clearly the drop starts at 70C which is more intuitive. Still, keeping GPU temps even under 70C on air can be a challenge and/or very noisy, so even if the threshold is at 70C, this doesn't detract from the appeal of water cooling in my view. Yes, but the fact that cores get minimal use can be misleading and doesn't mean that the GPU can't get moderately hot - this is due to the heavy memory controller load during mining. Going back to the miners' advice, for them keeping the GPU chipset cool can be was an extra challenge if the space is was overcrowded with devices and insufficiently ventilated. This is an equivalent of mining on a laptop 🤣where keeping GPU temps <70C can indeed also be a challenge. I am not 100% sure we are talking about the same thing, but I do see low temp throttling in practice as well. So annoying. In case the GPU is lightly loaded, say < 20% the clocks dial down to sometimes as low as 50-60% of max. This is despite max performance power mode being set in both Windows and Nvidia control panel. If anyone is aware of a workaround, I would be grateful. As soon as load goes up, so do the clocks (and consequently the temps). Nvidia, just because the load is 20% doesn't mean I'm OK with it being processed much slower to save power! Goofy indeed. BTW I tried the latest Nvidia driver 522.30. Definitely a keeper, up to +2% in *some* benchmarks!

What a mess. Wonder if the fixed the 21H1 issue with Capability Access Manager Service randomly waking up to consume massive amounts of CPU, or whether they added more bloatware on top....

That's quite unexpected, obviously not something one would be able to observe with air cooling. How much % performance loss are we talking about between say 40C and 65C? @tps3443could you run a quick experiment to roughly quantify this (assuming that @Mr. Fox's temporary 3070 is not WCed)? Could just run a GPU benchmark of choice twice: with 40C temp target and 65C temp target (assuming you can control this via cooling only), everything else being equal. Good point about the memory temps, I guess the assumption is that memory has higher temperature tolerance. The 3090 suffers from a specific issue - I don't remember exactly, but it is a combination of chip types and insufficient memory cooling due to 2-sided card design. I recall that on the 4090 all mem chips are on one primary side of the PCB, and mem temps are much lower. That said, while Ethereum mining was memory bandwidth bound, it would still load the cores to decent temps so the recommendation was probably based on some emprical results in terms of the ratio of failed cards operating in certain conditions.

Also great, I mean either is fine in practice. The recommendation I've heard in the context of mining was to keep the GPU under 70C for any long term use. If we were to draw precise comparisons, we would need a few more pieces of data here: ambient temp, noise level (dBA) and ideally extra electricity required to achieve the given temperature (e.g. someone could be using a 500W cooler/aircon unit).

40C 🤣

I presume that the external reservoir setup makes the maintenance that much easier, or does it not matter?

Pretty cool, thanks for sharing. Can't really fault this kind of look: With 18 fans this will cool down anything. Nice job with the reservoir extension too, the whole setup has a mildly mad scientist vibe to it. I like 🙂 Edit: BTW For those less mechanically equipped I assume there are some external reservoir stands too? Overall this stuff basically solves multi GPU cooling without limited and dubious top-bottom in-case radiator setups as per LianLI D001 (or something like that).

Apart from the copying issue, how is 22H2 performance looking in gaming for instance?

Ha. I'm liking the idea of liquid cooling more and more. The main problem with the external radiator grid I've found so far is aesthetics. Didn't anyone come up with a nice chassis for this, for those who don't have the time/skills/tools to make one?

Not all apparently, only the ones involving their products 🙂 Apart from the somewhat unsightly external multi-radiator grills, there are the freezers - this is supposed to generate just 20 dBA noise, less than the new EVGA fans 🤣 https://www.aquatuning.co.uk/water-cooling/radiators/chiller/7248/waterchiller-hailea-ultra-titan-150-hc130-110watt-cooling-capacity?c=2745

Alright, that's good - the nightmare scenario is the installation failing while unattended. So was it worth it in the end? For me the extra hassle (and perceived risk) never seemed to justify the effort however, I am beginning to see the appeal, especially given the fresh realisation there is the distilled water / low conductivity liquids option. Of course, looks like a decent CPU+GPU loop would cost a good few hundred $. Can you even cool someting like a 3090/4090 + 12900KS using a single thick 360 radiator? At the moment the CPU AIO coolant temp is maybe around 35C, so seems like there is headroom. Edit: Nope, need two radiators therefore a new case or one of those external radiator setups...: https://customerservice.ekwb.com/hc/en-us/articles/205235861-What-size-radiator-do-I-need-for-my-system- Gosh, that's fugly... sorry. The other question is: how often does one need to service the setup? AIOs claim 5 years+ lifetime.

You're right of course. There is actually another header (which confused me) but it's not powering the fans, it's just for the RGB. Sorry, I couldn't actually look on the other side of the case so took a bad guess 😕

Must have been a bit annoying/laborious to deal with. How long did it take for the leak to develop?

Could you please explain this build a little? Where does the black tube go? An uber external reservoir/pump/radiator presumably?

This looks really tempting, but wouldn't there be more of a leak risk when going with budget components? For me the biggest draw would be the ability to use slim liquid cooled GPUs, but that seems to involve custom water blocks, at least for the 4090 so far?

Interesting point, but it seems that fans and pump can't can be independently controlled on the Arctic. Anyway, good thing it's so quiet it can also be run at full speed no probs (as I have to do anyway) 🙂

Not necessarily. Some fans are louder along the entire RPM curve. In other words, you might need to turn them down to a much lower RPM point (obviously resulting in worse cooling) to achieve the same noise level as fans with better accoustics. If you look at the specs, even if you turn the EVGA fans to the minimum, they will still be louder than the Arctic fans at max speed.

Ah, you're right. Still, those seem to be very loud fans. The fans in Arctic Freezer II ARGB are 0.3 Sone which apparently is 10.6 dB... I understand that the impact of RGB on fan characteristics has more to do with the additional resistance / airflow disturbance caused by the LED+wiring. The amount of heat emitted by these in operation is negligible.

My bling bling was already on, but then again there is no cooling issue to worry about at present. If there is in the future, the RGB fans will be the first to go. Whether they are good or not depends on the criteria, but yeah, they look quite powerful. That said, they don't specify noise levels, probably for a good reason 🤣

The new bling bling will look nice in open/glass cases, but will probably provide slightly negative value in terms of cooling performance. RGB fans perform strictly worse.

Fun, but ultimatley close to worthless video, even if not fake - yes, if you are GPU limited a faster CPU won't help average FPS much🙂 Just 3 more days to real benchmarks people! This will turn out to be a good upgrade for both professional applications and enthusiast gaming. A healthy boost in clocks plus the 60% increase in L2 cache size (and potentially the stock 5600Mhz DDR5 support) should translate to meaningful improvements. I am just a bit worried about the L3 cache. Unfortunately, with the likely 5 month+ gap between this and the KS, a purchase will be hard to resist especially for those in an urgent need of a CPU power boost.

"The RTX 4080 12GB is a fantastic graphics card, but it’s not named right. Having two GPUs with the 4080 designation is confusing." Translation: damn, this Ampere stock really isn't selling and we refuse to discount it because the ever so pleasant memories of the glorious mining bonanza are still too fresh. Consequently there is no point in releasing a $1k Ada card yet, let's go to plan B and kick that can down the road under a plausible pretence we had cleverly prepared as an option in advance. Nvidia RTX 4080 12GB performance mirrors RTX 3090 Ti without DLSS 3.0
