Hello all. I am about to embark on a high-end build and while I have some experience from my last two builds, this time I want to make extra sure all the hardware I am gonna use are a-okay to run in the least possible amount of complications possible when eventually assembling. I am a triple A game player with a 1440p 144hz current system and am planning to upgrade to 4k 144hz+ in the near future. In the past, I have always had SLI systems but nVidia is killing the SLI driver support for new games this month and therefore I started putting together a list of my future specs. Some of my questions are very basic, some will be very specific. First of all, let's go through a list of all the hardware that I plan on using:
https: // ca.pcpartpicker.com / list / ZWjRHz
 
Case: Lian Li O11 Dynamic XL
CPU: AMD Ryzen 9 5950X or 3950X, depending on availability
CPU Cooler: Corsair iCue H150i AIO, top mounted (Push + Pull)
Motherboard: Asus ROG Strix X570-E Gaming
RAM: G.Skill Trident Z Neo 32gb (2x16gb) 3600mhz CL16 DDR4
Storage: Samsung 970 EVO Plus 2TB M.2 2280 NVME SSD (Windows + Games)
Storage: Seagate Barracuda Compute 2TB 3.5" 7200RPM HDD (Slave)
GPU: EVGA RTX 3090 K|NGP|N Hybrid, Front (side because of the Dynamic XL) mounted (Push + Pull)
PSU: EVGA G5 850W 80+ Gold
Display: Either eVe Spectrum 4k 144hz or LG 27GN950 (no stock anywhere)
Alright so here are the questions I have:
 
1- Will I be able to fit a push/pull system both on the top AND on the front of the Lian Li O11 Dynamic XL case ?
First of all, I did watch Steve's great "documentary" on gamersnexus and will mount both of my AIOs adequately. But, as I am already running a push/pull config with my H100i actually in my "Super tower" from Corsair, I remember back 5-6 years ago you had to pick a very very big case to be able to mount a push/pull on the top since most CPU VRM plates and RAM didn't allow for that space. And that is why I want to be sure before I go ahead and order all of those fans.
 
2- Regarding my fan set-up and air flow/pressure, Here is what I'm considering on doing.
Intake: 6x 120mm fans on the front(side) rad, 3x120mm fans OR 2x140mm fans on the bottom
Exhaust: 6x 120mm fans on the top, 1x120mm (or 140mm?) on the rear
Will that be too much in take for the exhaust I have ? I could drop to a single fan at the bottom of the case to help with the K|NGP|N's hybrid cooler and VRM temps if that's best. As for the fans, in the past I have always used Noctua NF-F12 3000rpm everywhere, but this one time I am strongly considering a white case and some white Corsair LL120 2200rpm RGB fans to reduce fan spin noise a bit.
 
3- Regarding those 14 or 15 or 16 fans, I have never had that many and therefore am not sure what would be best to plug them as I am pretty sure that my motherboard won't have 14 SYS_FAN ports. I am also considering buying a Corsair Commander Pro to sync all the RGBs together, but am just now noticing that it only has 6 fan ports, so I would be unsure what to do with the remaining 8 or 9 or 10...
 
4- Regarding the Mobo choice, I am also considering the ASUS AM4 X570 Crosshair VIII Hero since I have read tremendously positive reviews and have seen it in a ton of builds since 2019, but I can't tell the difference between the two of them, even when I use the compare tool from newegg. I'm like 99% sure both of them will have enough USB ports and a user-friendly BIOS for all of my needs.
 
5- Regarding the CPU: AMD's Ryzen 9 5xxx series just came out in nov. 2020, but I can't see any stock anywhere for the 5950x and therefore am guessing that the best purchasing option for these is to sign-up with an auto-notify system just like EVGA's K|NGP|N purchase queue, but with amazon or newegg ? And furthermore, is it worth the wait for the 5950x or should I just pull the trigger on a 3950x when I get the Kingpin? From what I've read, they are both of the Zen 3 architectures so am unsure of the difference between the two models.
 
6- Regarding the PSU, when I used the power calculator tool from EVGA it recommended a 750W PSU but I want to leave some headroom for OCing either CPU or GPU in the future. I am therefore wondering if a 850W is enough room or should I go straight for a 1000W ? Is there a downside to picking too big of a PSU?
 
7- Regarding the Display, recently a linustechtip review for the eve Spectrum 4k 144hz monitor came out and it wasn't too positive. With that in mind, I am considering pulling back on my contribution to their kickstarter and just trying to find a LG 27GN950, which is the panel that the eve spectrum 4k 144hz uses anyway. However, stock for this monitor seems to be a son of a gun and am not looking forward to another auto-notify or queue system. I guess it wouldn't be too bad though because I could keep using my current 1440p 144hz monitor in the meantime.
 
Last but not least, while these are the questions that come to mind, I am also accepting all suggestions/criticism/hints with this build.
Thank you very much!

 My only gripe with your list is the Samsung 970 SSD. PCI gen 3, not gen 4. You can get faster with the 980 or the new WD SN850 line.
 
Start buying what you can get and keep scouring for opportunities to buy that CPU. That seems to be super elusive at the moment.

The 980 line doesn't seem to have a 2TB option out tho, or at least not on newegg.ca. This is a dealbreaker for me. I currently have a raid0 with 2 500gb SSDs and it's almost already full since we now have 150gb+ games. Should I just get two 1tb 980 pros?
I also just signed up for an auto-notify on three retailers for the 5950x. We'll see what happens.
I think I will cancel my eve spectrum kickstarter and keep using my 1440p 144hz until the 4k 144hz is a bit more available.
Thank you castrator !

Honestly; when it comes to loading games, etc. going from M.2-3.0 to 4.0 speeds is nearly irrelevant; no need to RAID the new ones! Buy two 1TBs, if you want.
Keep an eye over at r/HardwareSwap for people who'd be willing to sell/trade/ship a 5950X to you.
 
Even with a 3090, 4K 144Hz is still asking a bit too much of it in modern titles.

I know I'm mostly replying to myself with this but for those who are lurking/reading, here is a list I just put together of the specs that I currently have, this will be what I upgrade from: https://ca.pcpartpicker.com/list/dkmB4d

Everything sounds great , except the PSU.     
 
Even the 3080 cards are melting some 850W psu's.  I would highly recommend you get no less than 1000 W Platinum/ or Titanium rated power supply for all that gear.  preferably 1200W - 1600W

I don't have an answer for all of those, so I'll just list out my 2 cents.
 
The case you selected is really geared towards custom water cooling builds.

Yes, that's true. However, I feel like I'm not at that knowledge point in my life and will still do AIOs and air. I read/watched a few reviews of the Dynamic XL for air and it's still very good. The gamersnexus one was the most convincing. Thanks Steve !

 If you are going with a RTX 3090, go 1000w or higher. If you score a RTX 3080 instead, the 850w should be okay but i'd still recommend 1000w.

Alright, as per yours and aka_STEVE's recommendation, I will switch for a 1000W.

If you are looking for the best gaming monitor, you should probably check into one of these:
https://www.samsung.com/u...onitor-lc32g75tqsnxza/

That monitor does look dope. I have never tried curved, I've always felt like it's a "gimmick" and isn't really needed.
Also, I kinda told myself that if I were to upgrade, it would be a mark up in terms of resolution. That's why I was gunning for the 27GN950 or the eve Spectrum (that was just further delayed, rip me).
I will definitely keep the G7 in mind tho, I've heard great things about it.

Usually, most modern mobos have 3 or 4 spots to plug fan headers into. Most have PWM headers for CPU fan, AIO pump, Case 1, Case 2, etc.
 
You'd put your set of 4-6 fans into a controller hub. The controller then plugs in using a single USB header port. You can control individual fans through the maker's controller software or the entire set of fans hooked into the controller through the PWM header that you can plug in to the mobo pins I mentioned earlier.

Okay. I just spent the better part of the afternoon reading on Controllers, hubs and headers. I think, since I will be using tons of fans, I will use an internal USB Hub like this one https://www.newegg.ca/p/0J2-009Y-00003?Description=nzxt%20internal%20usb%20hub&cm_re=nzxt_internal%20usb%20hub-_-0J2-009Y-00003-_-Product and use double-sided tape to place it on the inside of the case.
Thoughts?

You're going to connect multiple controller hubs to that? I don't know how well the individual addressable lights will work off a splitter. Something like the iCUE Commander PRO lets you control 6 fans, so two of them is 12 fans. If you really want the fans underneath the radiators to have RGB control you might email Corsair for what they recommend. Somebody probably makes a compatible splitter cable, the issue is RGB splitters tend to be proprietary and I don't know what would work with Corsair's own but they would. (For example Cooler Master has these). 

Interesting... well good luck with it then!

Hey all, as I read more and more on the 3090 KP I see that people report very high Backplate RAM temperatures and therefore am a little worried about the long-term life of my future KP. Now, I know that Lian Li manufactures "vertical" GPU display mount/cables (https://www.amazon.ca/O11D-1X-Premium-Extender-Riser-Bracket/dp/B07F6TY23V). I haven't looked too much into them because I didn't think it was necessary for this build, but with the O11 Dynamic XL bottom fans, I am now wondering if that would be better for said high backplate ram temps. I haven't seen a build with a Hybrid KP displayed in a vertical position with one of these, I was wondering if any of you had any thoughts on if it was relevant or even doable at all. Maybe it's not because of the pump or anything like that and I am too dense to figure it out? Hit me up !
