Still working on it over the weekends when I have some free time. Let me know what you think of this new Mach 3 version of this. The last 2 versions can be seen in the previous post. The link is still the same

Thanks Reddit, Much love

Thank you again for all the help on our little weekend project. Couldn’t have done it without you.

Working on a few more things like having presets for the more popular cases as well as figuring out the 120/140mm fan situation which isn’t really a big issue other than visually as you can adjust the CFM which reflects on how the fans perform irrelevant of size.

Thanks again. The link is still the same if anyone wants to try this tool out

Original post from about a week ago.

This little weekend project has been fun. Thank you all for the feedback.

You can try out the new version using the same link as before: https://fanconfig.mivibzzz.com

I think this version is much better than the old one thanks to all the feedback. Hope this helps with your next build. Still going to be tinkering with it to improve some things on it. Looking forward to feedback. Should work much better across devices in this form also.

What it does

• Plan your fan layout in 2D, then watch the airflow in 3D.
• It simulates how air actually moves: intake fans pull in air, it travels through the case, warms up, and exits through the exhaust fans. You can rotate the case and watch it from any angle.

---

What you can configure

• Case size: Adjust width, height, and depth (150–700 mm) or use presets like Compact, Mid Tower, or Full Tower.
• Fan positions: Choose where you want fans (front, top, rear, bottom, or side), and how many (0–4). You can also select different rear layouts (1 top, 2 stacked top, or 1 top + 1 bottom).
• Fan settings: Set RPM (0–2000), choose intake or exhaust, pick color (black or white), and select blade type (normal or reverse).
• Global controls: Apply settings to all fans at once, toggle airflow particles on/off, switch between 2D/3D views, and save your setup as a PNG.

---

What it shows you

• In real-time, it gives you data like:
  • Intake, exhaust, and total CFM
  • System pressure (positive/negative/neutral)
  • Air changes per minute based on case volume
  • Total system noise (dBA)
  • Power draw in watts
  • Number of fans

Each fan’s CFM, noise, and watts are calculated based on its RPM (74 CFM at 2000 RPM, scales linearly).

---

Other features

• Mobile-friendly: The layout adjusts for phones, and particle count is auto-scaled to keep things smooth.
• No tracking: Everything runs client-side—no data is sent anywhere.

Would love to hear feedback—especially from anyone who pays close attention to airflow when building a PC. What other stats or options would be useful?
