Review: Great Fans To Help Move Heat From Confined Spaces - Noctua are a known and very good brand of fans. I don't use Noctua as my case fans as the aesthetic does not fit my build. However, the back of my PC gets very warm. I am running a 5080 and a 13th Gen Intel along with a 1000W PSU. This generates quite a bit of heat. Whilst the case fans (Lian Li TL LCD and non-LCD) do a great job of getting the heat from the main case, heat accumulates in the back where my cabling is. I have put two of these very small fans in the rear of my case to help exhaust some of the heat and reduce the temperature inside the cabling compartment. They are PWM so I am running these from their own header and set the fan speed to around 80% minimum which is around 5000rpm (in the BIOS with System temp as the monitor). If the system temp gets over 45 deg, the fans will ramp to full speed which is around 5500rpm. These do not move massive amounts of air like case fans do, but they seem enough to deal with light scenarios. They function as they should. Fast and very, very quiet. In fact, so quiet, I cannot hear them at all (but they are in the rear so quite well sound insulated). Pretty good value for money. At £14 per fan, they are not the cheapest, but you are paying for quality (they come with a 6 year warranty which is nice). Plenty of cabling options in the box also. You might need an extension cable if you have a large case and, therefore, quite a long run. Overall, they are small, spin and move air in the direction you want! For reference, mine are in the rear compartment of a Lian Li Evo XL case running 3x140mm Lian Li TL fans, 5x120mm Lian Li TL fans, 3x120mm Lian Li TL LCD with 3x120mm Thermalright fans behind the radiator (as push-pull), MSI Z790 Edge ti max wifi MB, Corsair DDR5 (OC'd), Intel 13700k (Oc'd) on a EK open loop, Gigabyte RTX 5080 Aero (OC'd), Corsair HX1000i PSU - i.e. quite a bit of heat being generated!
Review: Quiet and Great quality - Quiet and cheap. Worked well for a PI NAS, would use again. Noctua quality is always well put together.

## 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

### ⭐⭐⭐⭐⭐ The best case fan I've EVER bought!
*by J***L on 8 December 2019*

It feels a bit strange writing a review about a small case fan, but I'm so impressed by this one that I had to share my thoughts. I've built plenty of PCs, and used many different kinds of case fans, but this particular build is a fanless PC that I upgraded to use a second SSD hard drive. I noticed that the temperature was increasing a bit to over 50C - still in the SSD safe zone, but higher than I wanted so decided to add a case fan, accepting that it would probably be quite noisy. Not so! This fan comes with all the connectors you could need. I used the Low-Noise Adapter with the extension, and the anti-vibration mounts, and the result is almost silent operation. The fan speed varies properly according to the SYS_FAN output on the motherboard, and the temperature of the SSD drive no longer exceeds 36C. I have to say a word about presentation, as the packaging is incredible (considering it's a case fan)! The box has to be the most luxurious packaging for a case fan that I've ever seen. The box has flaps on the front and back so you can see the fan and the anti-vibration mounts, and with information about the fan. Opening the box reveals well presented accessories and the fan itself. I feel that the effort spent on packaging (while probably reflected in the price of the fan) reflects really well on the manufacturer. Overall, while this is not the cheapest case fan around, for me it represents the best value, and the near silent operation was a real surprise. I highly recommend this fan.
