KF-101-IPF Double Fan Cooled Mobile Harddrive Rack
As with the triple fan model, this unit was also constructed very well
and was very durable and sturdy.

Now when you pull the tray from the frame you will be greeted
with a different connector than the 3 fan model. Here is a couple of pics
of the connector which again carries the power and the data signal too
and from the actual drive.


Now other than that, everything else is pretty well standard and is identical
to the triple fan version. The one main difference and advantage is the
cooling. All the cooling is contained within the harddrive tray and is
far superior.

Now, instead of two front intake fans, you have one, but that is not
the advantage. Here is a pic of the improvement.


Contained within this model is a large bottom fan which will do a great
job in getting rid of the heat accumulated around the bottom of the drive
where most of the circuitry is found.

A good close-up shot of the fan.

And it's exhaust port which will move the harddrive's heat into the case
to be removed by your case ventilation. Now this is good example of some
well-engineered cooling. The larger amount of airflow leaving the tray
than which is being brought in will create a slightly negative air pressure
environment and everyone knows that negative pressure is needed for optimal
cooling. Here are the results of the temperature Measurements.
Temperatures:
| Normal without Rack |
29 Degrees Celcius |
| With Rack installed |
25 Degrees Celcius (A Great Improvement!!!) |

Out of the two models, I would pick the two-fan model for it's more efficient
cooling and it's better engineering.
