You need to identify which leads on the Noctua are 12V and Ground. The colour code is not obvious. The Noctua does come with a short 12v + Ground cable to adapt the pins to whatever plug you are connecting too. It comes with handy Scotchlok connectors to facilitate this. **Q: Which way round to install, blow ambient air onto the hot area or 'suck' air away from the hot area ?** A: Only true answer is try both ways and see what works best for your setup, I have mine blowing on the components but they are right next to an intake fan **Q: Could i rewire this to a gpu ph2.0 mini 4pin? the 40mm fan on my motherboard is dodo, but uses this connection instead of a standard 3/4pin header.** A: As long as you know which wire is which on your motherboard yes absolutely ## Frequently Bought Together - Noctua NF-A4x10 PWM, Premium Quiet Fan, 4-Pin (40x10mm, Brown) - Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/71150023-noctua-nf-a4x10-pwm-high-performance-quiet-fan-40mm-high](https://www.desertcart.us/products/71150023-noctua-nf-a4x10-pwm-high-performance-quiet-fan-40mm-high) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-15*
