Product Reviews
- “Overall, this is the best case fan I’ve seen in a long time and although many people will quibble about the high price, in my opinion it’s fully justified for the quality of the product that’s achieved.”
- “Simply put, Noctua have a very quiet but effective fan with the NF-S12B FLX. The NF-S12B's role is predominantly as a case fan, but we have seen that it can be used to good effect with a CPU cooler. If equipping my case though I'd be inclined to use a mixture of the NF-S12B FLX as case fans and the NF-P12 for the CPU cooler or radiator.” (NF-S12B FLX)

Yes, you heard it right. Those clever chaps at the Institute of Acoustics have come up with a fantastic way to keep your PC cool n quiet. Build a good quality fan with silent bearing mechanics, angled bevel blade technology, an odd khaki colour and hey presto - it works!! These really are quite expensive but very, very good fans. I have had stock Thermaltake/Coolermaster and paid-for Zalman/Akasa fans but forget the rest - just buy the best. I guarantee no disappointment. With silicone fastenings, resistor cables etc it is just amazing. Joy, joy, joy!!!

When I replaced my noisy stock AMD CPU cooler with a much quieter Arctic Cooling Freezer 64 Pro I found the stock 92mm fan fitted to remove the hot air from the case was also making a lot of noise, so I decided to do the job properly and looked around for a 120mm fan, and after reading dozens of reviews and reports purchased a Noctua NF-S12B FLX, yes it did cost a bit more than the majority of fans on the market, but the old saying is certainly correct, "You get what you pay for" and for the amount of time I spend on my P.C. it was well worth it, it also dropped the case temperature down a couple of degrees, it is certainly the quietest fan I have ever heard, even on the highest speed, and am very, very pleased with my purchase from Quiet PC.
