Scythe Mini Kaze 2, Quiet 40mm Fan, 3500RPM, Single Pack

Added one to a Adaptec RAID SAS 12Gb/s card CPU heat sink... saw almost -10 degrees Celsius drop in temps... Wow (MaxView Manager software stated chip temp. around 54-55 before, after install 47 degrees). Installed in a home server NAS case with little airflow around mobo and the manual said 200LFM required. First photo shows heat sink without fan. Last two photos show mounted fan to heat sink.After that I upgraded my older NAS home server case, similar design with most airflow pulling through the HDD hot swappable bay area and not mobo. This time on a LSI SAS 12Gb/s card with similar heatsink. Mounting was not perfect but does the trick. The last two photos are of the LSI MegaRAID controller, as you can see different sized heatsink and had to mount off center but have not seen any errors yet.Both cards were purchased super cheaply used of eB... so don't forget to reapply some fresh thermal paste while your at it!

I have a Asus Strix TRX40-E Gaming motherboard with a hot chipset, it went from 76C to 73C after replacing the thermal paste, but that was still too close to the 75C "critical" temperature Asus uses to spin the chipset fan to 100%. Used 3M double-sided tape to "install" this fan on top of the chipset fan cover (with the chipset fan still running as normal), and then some electrical tape on the sides to seal the airflow. 73C -> 69C. Nice. It's set to 70% speed via DC control. You can hear it (if you try) at 100%, but otherwise silent. Does the job!

I bought this fan because I was disappointed with the clumsy 3-pin to 2-pin adapter I would have had to use with the Noctua. I have a small case to fit one of these fans into, and all that extra cabling the Noctua had because of the extra length the pin adapter adds is unacceptable.This fan is just a quiet as the Noctua, pushes a comparable amount of air, is cheaper, the cable is the perfect length, and has a 2 pin connector! A winner hands down!

It doesn't move as much air as the 40mm fans that sound like jet engines but it's not meant to do the same job. This fan is not as silent and does not seem to move as much air as the Noctua I have but it is very close in both respects. It would probably be a good choice for a Raspberry Pi case that accepts a 40mm or any other application where it will blow directly on a heat sink and you want quiet operation. I'm using one in a custom mount to cool an IBM PCIe quad NIC and it is working well.

Tried replacing the 4000RPM fan in my Security Camera NVR. Boy was that a mistake. Huge wine on power up, at least twice as loud as the stock fan, peaking at 60 dbl..

I don't have a noctua since I refuse to pay 15$ for one fan but I installed this to cool the case for my ender 3 pro CPU and its whisper quiet and puts out more air than the stock fan. You will need a Buck converter to knock the power down from 24 to 12 if you want to us it in this way.

The fan is very quiet and other than changing out the connector it was a breeze to install.

Used this in my Asus motherboard to keep my name cool. Runs full speed and can barely hear it.
