Customer Reviews

Very quiet for its size


I used this to replace a 40mm 'screamer' in a PSU. This one is indeed very quiet and pushes enough of an airflow to keep the unit cooled too. I've dropped 2 stars because of the cable on this fan. It is simply too short to do anything with, and I had to get the cable modified to make it longer, which means my warranty is not valid and it ended up costing more than it should. As supplied in the box, the cable is barely 4 inches long. The product page on doesn't mention this either.

Overall very quiet as described but investigate your cabling options carefully when considering this fan.

Delivery from flawless as usual.

Good to quiet Microserver N40L


A great replacement fan for the noisy 40mm PSU fan in Microserver N36/40/54L.

Only issue is the cable on the Scythe is about an inch too short - needed to splice and solder a slightly longer cable to make it fit.

Talk About Quiet.


I purchased a Pro Powered Mixer but sadly the cooling fan was to say the least loud, though for stage use would have been fine, but in my lounge not good, then I found this site and took a chance in opening up a brand new piece of equipment to see what the fan was, then I ordered two fans from here and had great service and very fast delivery, removed the old and in with the new, and what a change, now you can't hear any fan noise, a fantastic product and I thank Quiet Pc, and will recommend them to anyone, if you want a quiet life this is the place.

Scythe Mini Kaze Ultra quietly rocks


I bought this fan as a replacement for a very noisy (you could hear it from the next room) Cisco Catalyst 1924 fan. This fan is so silent to you even forget that the Cisco switch still exists. I highly recommend Scythe Mini Kaze Ultra

Silence in a box...


Brilliant little fan, used it to replace the rather noisy fan in my SKY+ box (Pace 3100). Works great, almost inaudible. One note though, if you're thinking of the same thing (fitting it in a PVR) you may want to look for some different screws as the ones supplied pass through the mounting holes rather than gripping...

Top score for delivery too! :)
