## Description

Premium 92mm fan with advanced acoustic optimization and Flow Acceleration Channels for superior quiet cooling. Ideal for CPU coolers, compact PCs, and other devices.

Review: Perfect as always - I used these for my 6800pro Ugreen NAS. They fit perfectly and the airflow is increased but the noise is much reduced allowing me to leave it set on default. As you would expect these fans came with loads of adapters etc and were well packed. they were sturdy and the rubber corners helped with my metal chassis. The performancce of Noctua is always great and to me the the little bit more thay cos is worth it.
Review: Excellent quality fan - Excellent quality PC fan, low noise and just keeps on working even after all this time. Highly recommend this fan cos.....I'm a fan....sorry couldn't resist :)

### ⭐⭐⭐⭐⭐ Amazing fan - quiet and moves a lot of air!
*by G***Y on 13 September 2017*

Back Story: I have a HTPC that has a small ITX case.. which had a nice low power Haswell Refresh I3 (4170T) in it and a lowish power gfx card (GTX 1030 - only 30 watts TDP).. This was used for casual gaming and media playback of movies etc. I started to get back into gaming after about 5 years away (birth of kids etc), and decided to up my processor and gfx card.. The CPU got upgraded to a Haswell I5 (4790K), and the wattage therefore went up from 35w to 88w. Unfortunately my Scythe Kodati CPU cooler was VERY noisy trying to deal with 88 watts as it was meant for only 65w processors. Solution: The solution was buying this Noctua NF-A9 fan. I took the stock fan off the cooler (an 80mm x 10mm affair), and strapped this to it with some heat resistant rubber bands used for cooking. It increased the height of the cooler from 3.7 to 6cm, but still enough room in my case, as I had a nax height of about 10cm. I then started up the PC with its new fan on the cooler, and et voila! A lot less noisy (Kodati fan was rated as 32db max, this one at 22db max) and actually allowed me to overclock a little bit (200mhz only) due to the extra air flow (from 24 cfm to 46 cfm)! It comes with a great range of stuff in the box too - a splitter, now noise adaptor etc. Very happy with the result!
