..just (= yesterday) got an Asus X570 Crosshair VIII Hero wifi on sale, as part of an 'emergency purchase' given that my oldie X99 Rampage Extr developed some serious boot issues, with Q-codes that make absolutely no sense (to be revisited at EHW...) In 'normal times' I would have preferred the 'Dark' version of this Asus X570 board, but the price - and availability right then - was hard to pass up. Unbelievable performance with a 3950X (which was also on sale, one of two available there), even if Asus' bios seems to not take true power consumption that seriously at certain settings (according to latest HWInfo). If you see this mobo on sale, go for it...

...PCIe distribution of the Zenith Extr looks like my MSI X399 Creation layout I run w/ 2950X...never had any trouble with that board (2 yrs plus) and it does have a U.2 which I like for productivity. And yeah, some of the upper-tier 'new old stock' X399 mobos are outrageously priced compared to the original, so hoping that your mobo is ok

...tx, bookmarked that; I need one of those in a short while

@Bastiaan_NL ...I think I might have a decent 3950X sample on my hands. Apart from InFin 1900 / RAM 3800 out of the box, I ran some Cinebench R23 for the first time. CPU is not oc'ed yet (panning to really delve into it on the weekend), and have only done some efficiency work so far. Also looking to undervolt the CPU a bit soon. @BWG ...that Heatkiiler edition is exactly the one I'm planning to get for the 3950X; already have the TR4 version of that - amazing quality, performance and reliability. Right now, the new 3950X setup is running on a BeQuiet PureLoop 360 (but w/ six Arctic P12 in push/pull) and doing very well for an AIO w/ thin rad, but I would like much more rad volume

...DerBauer had an interesting comparison between D5 and DDC at Caseking 'TV' channel on YouTube...Caseking is one of Europe's bigger distributors and also does commercial and gamer custom builds (they also own overclockers.co.uk). Long story short, both D5 and DDC are good pumps...DDC gets a bit hotter etc but there is one major point to consider: D5s have a larger diameter and can 'technically' flow a larger volume, but also are more susceptible to pressure drops due to their larger diameter when encountering hotspots (ie air pockets). HOWEVER, dual D5s in series pick up much more flow than single D5 when compared to dual DDCs vs single, and the at least potential pressure drop problem is completely gone. I've built quite a few w-cooled quad GPU + w-cooled CPU systems and always use dual D5s in series...5 separate water blocks (plus plumbing) can hide a lot of air pockets even after thorough bleeding whereby dual D5s tend to flush it all out while maintaining pressure if one D5 has a bit of a hiccup. The other reason for dual pumps is of course fail-over, especially in workstation and other commercial applications. One of these days I try a build w/ DDC, but it is also a question of inventory management - always using the same pumps and only one or two different types of rads makes it easier and cheaper to operate inventory.

...busted for speeding in your digital Bugatti ? !

...not only that, sometimes the interweb fakes that and other things too...

...in the larger metro areas, FS2020 uses satellite data, modelling and photogrammetry 'skin'... ? a re-post of a shot in Vancouver (extremely accurate, we live in that part of town). Then some new pics from Moscow in bright sunshine (real weather) from yesterday

...sometimes Canada stands in for Russia (and elsewhere...) in James Bond titles...Mt. Asgard, you can visit w/ FS2020 ?

..needless to add that I'm really looking forward to sink my teeth into this (don't have any background w/ AM4, usually just do AMD TR and Intel HEDT). The 3950X does seem to have a strong IMC +IF though...and I used one of my 'early' 32 GB GSkill 3866 kits (which is known to go up to 4133 before voltage increase in other builds). Problem is time - hyper-busy at work...wish I could just dive into it now.. ...all stock re. voltages. Haven't done CPU oc yet, been focused on IF / RAM

@ENTERPRISE ...great news about the upcoming marketplace, with special thanks also to @axipher & @Avacado ...cross-border transactions soon then... ..."From Russia Canada with Love"

...quick update on 'sealing' push/pull with electrical tape: I'm just putting together a X570 Asus Crosshair Hero VIII wifi and a 3950X...got a BeQuiet PureLoop for a very low price (and it's even refillable !)...while this AIO is a great performer as is, I took the BeQuiet fans off and mounted six Artci P12 pwm pst in push / pull. Even at full song, you can hardly hear them and manages to keep a 3950X in repeated Cinebench23 in the low seventies C. This unit will get a full custom loop as soon as the 3090 Strix block and backplate is settled on, but for now this is a more-than-decent solution. Pics below of the testbench for that, not final...note the electrical tape on top of the rad...still have to do some trimming, plus the sides...

^^That ! For a variety of technical reasons, I usually go with dual D5s per loop anyhow, but there's nothing stopping someone to add a D5 to one that comes with the distro. BTW, there are several 'custom' distro plates by ThermalTake for the Core P5 as well as Bykski and Barrow - or the whole Core P5 '''case''' is a distro...first shown several years ago, now finally available...must be pretty heavy though...

Nice ! I have a work-play TR4 / X399 MSI Creation setup that does all the heavy lifting...most reliable and powerful thing I built ever ..tx - was accidental more or less... tried out the 3950X and saw one core at over 4.7 GHz after 1st boot-up, a few others not far behind. For now I'm using a BeQuiet 360 AIO (but with six Arctic P12s in push-pull) and highest temp w/ 24 C ambient was 73 C in stress-runs of Cinebench 23....just got to get used to that idle voltage ?

...started to have irregular boot issues with my 6yr old X99...no time to fool around on a hybrid productivity / gaming system right now...so, I got this, at pretty decent prices actually. 3950X instead of 5950X, but at least it was actually there for pickup (1 of 2 left) instead of 'out of stock'. Custom w-loop comes later...

Tx ...I hope so...I did that with my 200GB cache but every time I go from one system to the other (never concurrently), there's all kinds Microsoft 'validation' going on...syncing both at the same time would be perfect.

....great ? .I get to download 'massive' twice, for two builds ?

...check out DerBauer vids on YT on this (multiple O11 builds, rad configs)...after all, his name is on the O11, too ? more > here

One quick tip when talking about positive pressure, push pull etc with PC rad fans in particular. More often than not, I noticed a tiny gap between the fan 'body' and the rad, often because of the vibration taps, sometimes because of the fan body design in general. With my GentleTyphoons in push/pull, I actually use electrical tape all the way around the edge of the 360 rads to seal that gap between the rad and fans...not scientific, but I think I picked up a 1 C+ drop, and also slightly better noise readings ?

Thanks ? ...good to know. I'm considering the Bykski for my Strix

...it's a long weekend here...lounging in front of a 55 inch TV with a big cup of java and pushing the 3090 a bit in FS2020. Enjoy the real-weather NY scenery:

" As it happens I still have some of those Gentle Typhoons hanging around never used lol. Wish they were PWM but generally speaking a decent DC control is fine if through the motherboard or external controller." ...ohh, but there's a solution: https://www.overclockers.com/high-speed-gentle-typhoon-pwm-mod/

...re. your question as to whether push+pull makes a difference, 'yes', but it depends to some extent on the rad setup (thickness, fin density) and of course the fans themselves. I build my first quad-SLI back in '12 and used a custom 1080x60 rad (equivalent to MoRa360) with 18x static pressure fans, 9 at the front and 9 at the rear...the difference on that particular setup was about minus 5 -6 C for the CPU under load but more pronounced when loading the Quad-SLI with benches. ...same with the 2080 Ti SLI-CFR setup, it uses 3x 360/60 in push+pull with GentleTyphoons (and one w/ ML 120s in push pull)...static pressure isn't a problem and the resulting 'noise' is largely mitigated by baffles I added (which also help airflow, btw) as those rads sit 'on their side'. Key is to have 'matched fans' running on the same controller - you don't want the fans to hinder each other ...with the Arctic P12 PST I'm just getting into, installing them on one side dropped temps by over 4 C compared to the ML 120s - and the P12s are amazingly quiet even at speed...adding push/pull to those tomorrow in the new build and will update here ? ...in the meantime, check this out:

Amazon and eBay for the 3090 Strix OC below as of today...I could more than double my money in two weeks...nutty times we live in. Point being though, keep looking for a good deal, there are some to be had behind all the scalper noise...

...some excellent points ! However I prefer not to mix anything into the final fluid combo before leak-testing. As I build both servers / workstations as well as fun machines, I have a setup with an external Molex that powers all the pumps etc for a new w-cooling build w/o having to turn the main mobo on. I let that run for several hours, power and cool down, than run for another few minutes - be that for a single loop or dual loops. More on fans below... ...I have a collection of the Noctuas - but that colour ! I use them for workstations that go into 'boxes', but for open builds, no thank you. I got so desperate on a personal TT Core P5 build that I actually spray-painted some Noctuas black (still work, btw). ...for benchers and heavy duty, I use the tried and true GentleTyphoon 4K rpm models, each w/ 183 CFM...they are for example on my GPU loop for dual 2080 Tis and they just keep everything below the first speed-bin loss...so far, I haven't been able to 'heat-soak' that GPU loop with 760 W in 2 years, and not for lack of trying ! ..we also have a big pile of repatriated Sunon 5K rpm server fans, but while they certainly cool very well, they just can't be used if you sit within earshot, whereby I find the GentleTyphoons 'somewhat bearable' ? ...GT 4K on the left, Sunon 5K on the right: ...lately however, I have been getting into Arctic P12 pwm PST fans - and I'm genuinely shocked at the great price-temp_noise performance ratio, especially if you buy the 5 value pack. Obviously I don't know yet how reliable they are over the longer term, but they sure beat the cr_p out of for example Corsair ML 120s, both in terms of noise at full tilt, and temps w/ all other factors held equal. I just put 5 of those into 'The Thing' (you know as the Strix 3090 OC testbench) - 3 for the CPU, and 2 for the GPU backplate (double-sided GDDR6X = toasty). When I watercool the Strix, I'll be using those. The question is whether they last as long as for example the GentleTyphoons (some of those are over 8 years old, & in continuous use...).
