"The F12 airflow is only about 13% lower than the S12A", lower in what? regarding the GPU thing, perhaps diagram is in order. the intakes would force the hot air back into the GPU and hopefully out the top. or at least a turbulence, mixing hot and fresh air together. I am no aerodynamics engineer, so maybe my visualized scenario is wrong. I doubt my air pressure brain-simulation.

I thought LNA stands for "low noise amplifier" not "low noise adapter". I for one thought that there's a circuit in there when I read LNA (its probably just a resistor). Silly comment but I had to.

The GPU is vertically mounted, meaning that it takes air in from the glass side of the case, and exhausts hot air to the top and bottom. The bottom intake fans would work against the GPU's exhaust + won't efficiently supply the GPUs fans with fresh air, hence the idea. My question is, for those bottom intakes, do you think that I should go with static pressure fans or airflow focused fans? I do not want to go with an allrounder.

Updated. Thank you for pointing it out

Hey guys, this is my first post (I think) and I don't usually post of forums/reddit, so please take it easy on me if I don't lay thigs out probably . I'll make edits as we go. I finally made the money to build my no compromise computer, bought the parts (Link: https://ca.pcpartpicker.com/list/P9kztn, GPU is vertically mounted) and built it last night. While I see the comments regarding the AM4 platform coming, this it not the help I need. No compromise does not mean optimization can go out the window, and AM4 fits my use case perfectly. My issues are not ground breaking, just annoying little things, mainly about the case. I'll put TL;DRs in bold (Most Important) Airflow or Static Pressure? I was feeling smart and got 4x Noctua A15 HS-PWM Black for the side (main) and bottom (GPU) intake instead of 3 by 3 120mm fans. It works but here's the thing. Its ugly, and that's not acceptable in a no compromise build. So I am opting to get Nuctua 120mms, but now I have a choice to make. The 140mm black fans come only in A flavor (all rounder), the 120mm blacks come in all flavors S (airflow), F (static pressure), and A (all rounder). I could just get the all rounder, but in black it is 150% the price + I am getting 6 of them. Also, I am not letting an optimization opportunity slip my fingers. I know that airflow is great to move large amounts of air (which is what I want), but it struggles with obstruction. The question is, how much of an obstruction is too much obstruction? or more precisely: are the dust filters on the side and bottom of the O11 D XL case too obstructive for 3x Noctua S12A PWM intakes? A clearance issue . The whole point of an XL full tower case is that I do not get any clearance issue and I got the NH-D15 cooler (you can't pay me to use a water cooler. it is not happening). But the outer fan has to shift up to clear the RAM, and now it looks ugly-ish. The worse problem is because of the shifted outer fan on the NH-D15 cooler, the glass side panel doesn't close up anymore! I had to replace the RAM with a shorter one and now it pushes right against the glass, and mayyybeee even flexing it a little (or the mobo, or the finn tower on the NH-D15). I wonder if that's ok or if the should remove that fan all together, reducing the cooler to an NH-D15S, since performance would probably not get a hit. I could also get a 120mm fan if I am worried about performance, but I decided against it since it would look like a compromise. I don't know what exactly to do in this case. I could just mount the extra fan at the top (there's nothing there atm). Since I am reconfiguring the fans anyways, maybe there's a better config (water cooling is not an option). Here's a summary Currently: Top: none, Bottom: 2x Noctua A15 HS-PWM (intake), Side: 2x Noctua A15 HS-PWM (intake), Back: 1x Noctua S12A PWM (exhaust), Cooler: NH-D15 (pushing on the glass side panel) I am thinking: Top: 1x Noctua A15 HS-PWM (intake), Bottom: 3x Noctua ForS12 PWM (intake), Side:3x Noctua ForS12 PWM (intake), Back: 1x Noctua S12A PWM (exhaust), Cooler: NH-D15S (outer fan goes to the top) Note: I am going to 3D print something to direct the airflow from the bottom away from the vertically mounted GPU's exhaust and right to its fans. Any ideas are welcome. I can 3D print things to accommodate wild ideas! I am against just slapping fans everywhere because it (a) worse for performance, and (b) wasteful and not optimized.

So did that work? I see the answer is "accepted" but there's no word from @Lord_Montague. I am not familiar with the culture on the forum and not sure what to make of it. I am currently planning out a build and all budget 12th gen mobos are made by Asus, otherwise they are either miniATX, only 2 RAM slots, or expensive. This would hinder the entire build. It also seems that there is a general XMP issue with these boards, not just the RAM sticks mentioned in the Reddit post (even if that's not the case, the ones posted are pretty much the only reasonably priced ones). To top it off, it is only sold by newegg (flashing back to the recent newegg/TechJesus battle )

October 2019 (will this end....) Btw, anyone got anything recently? They have resurfaced again asking people to reconfirm their orders. I was still an amature back in 2015 and used my university email for backing. Now that I have long graduated and lost that email (the entire university domain is changed now) and there's no way for me to regain my supoosed "account" unless they decide to reply to my email/chat/comments/FB chat. Oh, did I mention that they disontinued their twitter account? in KS recent update: Enter your information and it'll probably reject it (its been 100 years ago, of course it would). best option is to have your order ID to link it to your new email address, but surprise surprise, it must me in that long gone 4+ years old email (though I don't remember recieveing it, I probably recieved it after I lost access to that email) I also found a "warning update" from them which made me super worried (update #61): For the people who reprted to the FTC and such. Any updates?

Thanks @wojtepanik. thanks for the HDD recommendation. I just threw that particular part in for price estimation (the SSD choice is probably what I'll go for though). I'll keep in mind a WD one. Also, how do you define as "high end calculations". If you could provide some examples for me to compare with

Background: I am asked to get a "server" for our research group in the university with a budget of >3K CAD, and I thought I could just build one to pack in as much bank for the buck as possible. Now I should start with that it is not really a "server". We will use it to run our CAD simulations (something like ultrasim and Cadence tools) kinda sounds like a typical workstation. We call it a server because we access it through SSH sessions controlled remotely (hence me naming it workstation/server system). This kinda makes it hard for me find a proper guide online (because servers or workstations usually mean something else), so I am relying on the information I have gathered through watching countless hardware videos and reviews over the years (most of which are on LTT). I have watched the recent video What CPU to Buy - Late 2018 and started from there. Another build that I see very relevant is Ultimate Mega-Workstation PC Build Guide . in short, the system requirements are: 1- Handle intensive simulations 2- Handle multiple sessions of 1 3- Handle 1 and 2 for an extensive about of time (days) 4- Can be as loud as it wants to. RBG is not a concern. Current build: https://ca.pcpartpicker.com/user/himura/saved/ckMr6h <detals at the end> Burning questions: 0- The obvious: any overkills? anything I am missing? is this a good build? what would you replace? 1- This vs. ready-made workstations: This https://www.servergiant.net/product-page/dell-precision-t5610-6core-2-26ghz-workstation has a xeon and a quadro, but (8?) years old (ancient big guns). Should I just opt for this instead? it is cheaper. 1- Team blue's Xeons: Should I even consider these for my price range? 2- More weaker CPUs or one Stronger one? basically, I am debating if I should have gone for multiple CPUs (i5s or i7s) instead of the 2950X (keep the MB in mind)? Is there a way to have two 2950X in one system? 3- Water Cooling: I have decided to cheap out on this one and opt for a normal cooler since I don't see us overclocking this thing (I know that the entire system can be overclocked, am I missing alot and could have gotten cheaper/weaker parts?). 4- ECC memory: I know what it is and seems like it is needed, but I have never used a machine with ECC memory on it (even research servers). How can I tell if I really need ECC memory (also they seem to be slower). 6- Graphics: We don't need any kind of graphics card at the moment except for something to connect a display to for basic configurations. This system will almost only be controlled remotely. 5- Scalability: We might add one or two GPUs for parallel computations and such and I think that this build can handle that, am I correct? Also, we might need to add more memory. 6- Memory: Since the board is rated for dual and quad channels, I decided to get quad channels for more throughput. Is my logic correct here or am I better off with a 2x 16 GB kit? 7- Memory again: what’s the difference between F4-3200C14Q-32GTZR and F4-3200C14Q-32GTZRX (they are like 6 CAD extra). Will the X work on my X399A board (I can’t see it in the QVL)? (I chose F4-3200C14Q-32GTZR for now). 8- Power supply trivia: Is this have 2 8-Pin EPS connector? I tried to look but it said 4-20pin connectors which completely threw me off (I am nor really familiar with power supplies) Detailed build: Component Selection Base Promo Shipping Tax Price Where CPU AMD - Threadripper 2950X 3.5 GHz 16-Core Processor $1172.75 $1172.75 shopRBC Buy CPU Cooler Cooler Master - MA621P TR4 53.4 CFM CPU Cooler $79.99 $79.99 Newegg Canada Buy Motherboard Asus - PRIME X399-A EATX TR4 Motherboard $374.99 FREE $374.99 Mike's Computer Shop Buy Memory G.Skill - Trident Z RGB 32 GB (4 x 8 GB) DDR4-3200 Memory $641.00 $641.00 Newegg Canada Buy Add Additional Memory Storage Corsair - Force MP500 120 GB M.2-2280 Solid State Drive $89.99 $89.99 Canada Computers Buy Seagate - FireCuda 2 TB 3.5" 7200RPM Hybrid Internal Hard Drive $119.99 $119.99 Amazon Canada Buy Add Additional Storage Video Card MSI - GeForce GT 710 1 GB Video Card $51.15 -$10.00 $41.15 Vuugo Buy $10.00 mail-in rebate Case Deepcool - MATREXX 55 ATX Mid Tower Case $59.99 $59.99 Newegg Canada Buy Power Supply SeaSonic - FOCUS Plus Platinum 650 W 80+ Platinum Certified Fully-Modular ATX Power Supply $106.99 $106.99 PC-Canada Buy Optical Drive Choose An Optical Drive Operating System Choose An Operating System Software Choose Software Monitor Acer - ET.VS0HP.A02 23.0" 1920x1080 60 Hz Monitor $97.99 $97.99 PC-Canada Buy Add Another Monitor External Storage Choose External Storage Expansion Cards / Networking Add Expansion Cards / Networking ...
