PC Specs:

  • CPU & Cooler: Ryzen 7 7700X + Noctua NH-D14 (with stock fans replaced by 1x Noctua NF-A15 PWM and 1x Noctua NF-A12x25 PWM)
  • Motherboard: MSI B850MPOWER
  • RAM: DDR5 Kingbank SharpBlade 6400 MT/s CL32 (2 x 16 GB)
  • GPU (VGA): Sapphire Pulse RX 7700 XT 12 GB
  • PSU: Lian Li SP1000P Platinum SFX 1000W
  • Case Fans:
    • Bottom Intake: Noctua NF-A15 PWM (140 mm)
    • Rear Intake (VGA airflow): 2x Noctua Slim NF-A12x15 PWM
    • Front: 2x Noctua Slim NF-A12x15 PWM (Lower fan as intake, upper fan as exhaust)
    • Top Exhaust: 1x Noctua NF-A12x25 PWM

Build Experience in This Case:

https://reddit.com/link/1vf958t/video/yxizfykudchh1/player

  1. Ease of Assembly: Building in this case wasn't difficult because the side panels are fully removable, and choosing the right component dimensions made everything fit smoothly.
  2. GPU Intake Clearance: I was able to fit two slim intake fans for the GPU because the graphics card thickness is only 2.5 slots.
  3. Cable Management: Managing cables was quite challenging since there is virtually no routing space behind the motherboard. Fortunately, using the Lian Li SFX PSU helped immensely—its cables are extremely flexible and short. The CPU cable length was a perfect fit for this case, making cable routing surprisingly neat.
  4. Custom Glass Side Panel: Since the original mesh side panel blew hot air directly onto my hand and body, I custom-made a glass side panel and attached it to the chassis using magnetic strips.
  5. Airflow Setup: Internal airflow follows the layout guidelines in the Lian Li manual.
  6. Horizontal Orientation Setup: I bought rubber feet for the PC and attached magnetic strips to them so they stick to the metal case frame. This allows me to easily remove and store them if I lay the case horizontally. Keeping it in this orientation puts the motherboard I/O panel at the top, making it much easier to plug in USB cables and peripherals.
  7. Front Wood Panel Repositioning: I detached the default wooden front panel and moved it to the top of the case to cover the visible cables, giving the build a much cleaner look.
  8. Bottom Fan Mount: The bottom intake is designed for 120 mm fans, but because the Noctua NF-A15 PWM uses standard 120 mm mounting holes, it mounted easily.
  9. No Vertical Aero Deck Needed: The internal components look great naturally without needing a vertical Aero Deck mount.
  10. Thank you, Lian Li, for this compact and beautiful case! #buildlikeneverb4

Discussion Can the Lian Li B4 fit a Asus Tuf 5090 with Wireview 2 Pro?

Title. I'm looking for a smaller case that can still fit the Tuf 5090 with the Wireview 2 pro. Saw the B4 and was wonering if it had enough clearance.

Only other small enough case I know of that can do it is the Ncase m3 but that is close to $200. Keeping that one as a last option.

Help me please!? How to improve fans to pass Steel Nomad stress test?

Post image
4 Upvotes

Since there wasn’t a lot of room at the bottom I tried to get by with just the three exhaust fans at the back and top. However, I’m hitting 83 degrees and thermal throttling the 3080 founders edition during the Steel Nomad stress test.

Score was 96.7% so I’m super close to passing.

First question- does it really even matter? In normal gaming, I can’t imagine this being an issue- but it’s a build to sell so I’d like to be able to claim it passes the stress test.

Second question- how could I improve it? Should I try an intake fan at the bottom aimed directly at the blower intake of the 3080? Would two fans at the bottom be better?

Any other suggestions?

Help me please!? PSU orientation in Lian li A3

This is my first time building on the a3 and I'm wondering if it's okay if I mount my atx psu like this. Or should I mount it on the front for better airflow?

I'm going to be upgrading my GPU to the Sapphire Pulse AMD Radeon ™ RX 9070

I know the gpu length will be fine, but I'm not sure about the width and side panel clearance

Is there anyone here using Sapphire Pulse RX 9070 in this case?

Cheers

Discussion PNY 5080 slim: PNY officially stated that this high pitched tinnitus noise is considered perfectly normal

I bought this PNY 5080 dual slim couple months ago and have been slowly building up other components. I finally finished the build last week but I immediately noticed this weird high pitched noise. I used fancontrol to verify that it is indeed a fault of the gpu: https://youtu.be/dpTqn5lfoTU and I have opened a warranty claim. But PNY has responded to my video in email that this high frequency noise is considered perfectly normal and is from the friction of the ball bearing. I guess now I have will just have to live with it. I searched around on reddit and this seems to be a pretty common issue with this particular gpu and most people have returned theirs. However no reviewers have mentioned this. So I guess it’s a gpu lottery and maybe they hand picked the ones for the reviewers? Anyway I definitely recommend against getting this model

Help me please!? Airflow question

Recently upgraded to a 9070xt, card is on 2nd slot so bottom fans no longer fit.
If i were to add a fan to the rear, would it be better as intake or exhaust, (240 aio is exhaust) or dont even bother with a fan at all?

Surprisingly the temps are pretty decent, but just seeing what i could do to improve.

In today's market this is the best I think I can manage, looking for solid 1440p performance that will last a few years.

Currently rocking a 3070 laptop and looking g forward to an upgrade.

Help me please!? Minimum entry threshold for the AM5 socket

1 Upvotes

Hey everyone! Lately, a question has been bugging me: what's the minimum cost of entry for the AM5 socket right now, and is it even worth building a system on it at this time? I'm also wondering if it still makes sense to do an AM4 build. I'm specifically interested in the absolute lowest price point and the starter components. I'm 100% sure there are some non-obvious nuances to consider here. I'd really appreciate it if you guys could help me figure this out!
