My GPU Fan Saga – A DIY ATX Fan Controller

In plain words

My GPU Fan Saga is a DIY ATX fan controller project for enthusiasts who want to build their own GPU cooling solution. It provides guidance on constructing a custom fan controller compatible with standard ATX cases and components. The project is designed for users comfortable with hands-on hardware modification who seek greater control over their graphics card cooling performance rather than relying on manufacturer defaults.

Having a problem-solving mindset is incredibly valuable and rewarding, especially when it leads to exciting DIY adventures. My latest experience with a noisy GPU fan turned into just such an opportunity. It guided me through fascinating explorations involving ATX power, MOSFET motor drivers, Pulse Width Modulation (PWM), ATTiny85's bit-banged 1-wire …

  Llama 3.1 70B on a single RTX 3090 via NVMe-to-GPU bypassing the CPUFeb 2026 · github.com · ▲395

  Hi everyone, I'm kinda involved in some retrogaming and with some experiments I ran into the following question: "It would be possible to run transformer models bypassing the cpu/ram, connecting the gpu to the nvme?" This is the result of that question itself and some weekend vibecoding (it has the linked library repository in the readme as well), it seems to work, even on consumer gpus, it should work better on professional ones tho

  Free e-book about WebGPU Programming2024 · shi-yan.github.io · ▲471

  I am excited to announce the launch of my e-book on Graphics/WebGPU programming! This project has consumed much of my spare time, during which I developed various tools to facilitate the publishing process, including a code playground and a static site generator that can reference sample codes. However, I'm feeling burnt out and ready to call it finished, even though it may not feel completely done. Avoiding another abandoned side project has been my primary motivation in reaching this point.

  gpudeploy.com – "Airbnb" for GPUs2024 · gpudeploy.com · ▲267

  Hi HN, YC w24 company here. We just pivoted from drone delivery to build gpudeploy.com, a website that routes on-demand traffic for GPU instances to idle compute resources. The experience is similar to lambda labs, which we’ve really enjoyed for training our robotics models, but their GPUs are never available for on-demand. We are also trying to make it more no-nonsense (no hidden fees, no H100 behind “contact sales”, etc.). The tech to make this work is actually kind of nifty, we may do an in-depth HN post on that soon. Right now, we have H100s, a few RTX 4090s and a GTX 1080 Ti online.…

  I designed my own 3D printer motherboardDec 2025 · github.com · ▲127

  3D printing is such a fascinating field of technology, so a couple months ago, I decided to take a deep dive and learn how they actually work! This took me to one of my very first PCB projects, a small, cheap, 3D printer motherboard. While it's not the most cutting edge board, I learned a lot and I fully documented my process designing it (https://github.com/KaiPereira/Cheetah-MX4-Mini/blob/master/J...), so other people can learn from my mistakes! It runs off of an STM32H743 MCU, has 4 TMC stepsticks with UART/SPI configurations,…

  I built an under-the-door fan duct to lower bedroom CO22025 · lepekhin.com · ▲64

  Hi HN, This is my attempt to fix groggy mornings by lowering my bedroom CO2 from 1700 ppm to ~900 ppm. I designed a simple, 3D-printed fan duct that directs air under the door to improve air circulation. A note on the design process: I used CadQuery, a Python library for creating parametric 3D models. I didn't know tools like this existed and highly recommend it if you can program; it turned out to be more convenient than manually iterating on prototypes in a GUI. The project is open source and the post explains the full build. Happy to answer any questions.

  Trickle - Magic Canvas ▲1,064

  Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  Ten years of running every day, visualized▲958

  Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  Draw a fish and watch it swim with the others▲935

  Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

  Use Their ID – Use your local UK MP’s ID for the Online Safety Act▲862

  Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
