Until this week I had no idea what a Crossflow Blower was, I can now say I know what it is and I think it's an awesome product. Dynatron sent me one to review so what is it, how does it work, and how does it perform? Read on and you shall see.

Nice and professional looking box.


  • Size: 48X136X40.5
  • Weight: 191 gm
  • Fan speed: 7,400 rpm
  • Volumetric airflow: 11.12 CFM
  • Static pressure: 1.84mm-aq
  • Acoustic noise: 38 dBA
  • One power hook up connector, no connection for the motherboard to monitor speed.


  • Designed for the 1u/2u servers Raid storage
  • Angle of 180 degrees
  • Low noise with large air volume
  • Low electricity consumption
  • Fast and easy to install
  • Cool looking blades. When they are carved like this you know that you will get a good airflow.


    No screws or brackets were provided, there are holes already drilled in the blower, so what I decided to do was place the blower on the bottom of my case right in front of one of my intake fans. Once I found the right place for mounting, I used two self drilling screws that I had laying around to mount it into place.

    It looks alright being at the bottom. I tried placing the blower on my CDROM as well in front of my Harddrive but I didn't get as much cooling as I did with having it at the bottom of my case.

    When it's dark you can't even see it when my case fan LED's are on.


    Test Rig:

  • AMD 2100+ (Not Overclocked)
  • GA-7VRXP
  • Asus GeForce4 4600 TI
  • Memory 512MB DDR(Infineon)
  • WinXP Pro
  • I let my system idle for 30mins before I did any readings.

    As you can see my case temp drop by 3 degrees. Very nice. I didn't notice any drop on the CPU but heck I am already running Dynatron's Socket A cooler anyway. :)


    Cooling is very important to me and once again Dynatron has shocked us with another great product. The blower itself was a little noisy, but for the performance of this blower who cares. If you are running a server, high-end game machine or you may be using a case that limits the amount of case fans that you can use. Or, lastly, you're a cooling freak like me looking for that extra cooling performance then have a look at one of these. I highly recommend it.
