## Questions & Answers

**Q: is this the 5v or 12v model ?**
A: 12v

**Q: Can this just connect directly to a 12v DC supply or does it need to be a dedicated fan supply/connector?**
A: You can connect the Noctua to a 12v DC supply. 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
