Noctua NF A6X25 PWM Premium Quiet Review

High quality item. Not sure if the price justifies it, but definitely quieter than the factory fan on my HP 8300 Ultra-Thin Form Factor PC. There's still airflow noise that's inevitable with small, fast fans, but it doesn't have the electronic hum or any vibration noise that I've noticed with a standard fan. Fits perfectly, looks like a long life fan (enterprise grade). This. Its small bearings are of good quality and quiet, causing no more noise than air turbulence. Works well for the PC…

I'm amazed at how far computer fan technology has come, especially for a fan as small as this. I mounted it on my Supermicro MBD-X10SDV-4C-TLN2F-O passive heatsink with the included silicone feet and it dropped my CPU temp from 100C to 46C (and much quieter) from an HVAC fan. Normally I run like the plague in front of such a fan: 60mm fans and smaller tend to be annoyingly loud, high-frequency and poorly cooling. Not this one! It's perfection in a small package.

Great fans. Super quiet, long service life. I wish they were cheaper. I've used them on a super micro to quiet the CPU fans and it works great for that. Luckily nobody will see them because they are quite ugly. RE: Replacing a Supermicro fan with a KGPE-D16 mobile device with AMD Opteron. You should also replace the thermal paste. I got a -7°C drop with Thermal Grizzly Kryonaut! So if you're changing fans to something similar but lower volume, you should definitely upgrade your thermal paste…

These fans should be bought if you want to be sure you have the right cables and can handle the noise. They're very quiet to start with (which is good for a 60mm fan) and can then be made even quieter with the included adapter cable to slow them down even more. If your motherboard has decent fan controls you won't need these, but if you need to power them directly from a PSU they come in handy. They also come with extensions; The cables on the fans themselves are short, allowing you to keep the

I'm a skeptic by nature and have been very disappointed in the past when I've bought aftermarket fans to replace the ridiculously noisy factory fans that installed in devices. I've seen reviews saying this fan is good and generally considered a real bargain, but I've seen that before. I ordered a few of these (and other sizes) expecting to have to cut some strips of neoprene to glue them on to avoid vibration noise between it and the case. The first thing I noticed when this fan arrived was…

Love it! (see photo) I have two for my computer (HP P7-1010) to get more air moving there. Also bought one of the 40x40x20 little guys to get some air in the side port of my tower. These things don't move very much air. But nothing, that's all I could really do for my tower. Who cares about color? I think they look great. If you want more air movement I would buy Bgears fans. These things are about 50% more powerful than Nactua. I know these fans are rated at 3000RPM, my Bgears are rated at…

My home computer has seen three or four case fans in the last 18 years, but the Noctua fans I installed this year have made it quieter than ever before. The first installation was to replace the old noisy 80mm fan with a new Noctua fan on the front to blow into the case. It's virtually silent, but I didn't realize I had poor airflow through the case at the time. The power supply fan was not enough to release what the front panel fan was delivering. My CPU cooler isn't very loud, but it was…
