Dynatron Crossflow Blower

Today with PC's consuming as much power as they do and CPU's requiring heatsinks of huge proportions, we all know that heat can cause problems and cooling is a very important thing to consider when building a computer. Dynatron has sent us an interesting fan. Its a Crossflow Blower as they call it, designed for places that a standard high air flow fan won't fit. It is Primarily designed for 1U/2U server applications where a standard 60 or 80mm fan will not fit.

• Fan Dimensions : 48 x 136 x 40.5 mm
• Rated Voltage: 12 Volts
• Weight: 191 gm
• Current Draw 0.2 Amps
• Static Pressure: 1.84mm-aq
• Air Flow: 11.12 CFM
• Rotations Speed: 7400 RPM
• Noise Level: 38 dBa dBA

As you can see in the pictures above it is a rather unique looking fan. The fin design is that of a "squirrel cage". This works out particularily well because it allows the fan to be long and have a small diameter all in the same time. Only downfall to this design is that the fan is long. Its almost the same length of a 5.25" slot so length wise it takes up a lot of space. But at the same time the overall height of it is only 40.5mm so if your working in a space with little height and plenty of length this will work out well for you.

The motor for it seen above is just your standard magnetic motor that is found in practically every fan out there on the market now. As far as installation for this fan goes, I myself have never messed with a 1U or 2U case so I'm not real sure how they are designed. There are plenty of threaded holes in this fan so it doesn't seem as if mounting should be an issue no matter how your going to install it.

Since I don't really have a server case to install this in that will actually show the benefit of this fan I decided that it would work out good to cool the northbridge on my Epox 8RDA. It isn't very heavy so it was placed on top of the Radeon 8500 with some 2 way velcro tape so that it blows right across the northbridge.

I was quite surprised when I powered this fan up. Dynatron rates it at a measely 11.12 CFM but if you ask me its more in the 50-60 CFM catagory. I don't have the proper tools to measure air flow other than the human sense of feel but it moves probably about the same amount of air that my 68CFM Delta fan does. And to top it off this thing is actually very quiet. As you can see Dynatron definately has a different style of fan that could very well benefit the cooling in those rack mount server cases. If could also be used for a sweet looking case mod as in a HDD cooler of some sorts.

A special thanks goes out to Dynatron for allowing us to review another top quality product of theirs!
