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.
