Rubber areas prevent the cooler from sliding on your desk and two levers let you remove the plastic vent to gain access to the
fans. The four corners also house LEDs for fancy light effects.
The back is made from plastic, and especially the plastic vent doesn't feel as solid as I'd expect from a laptop cooler in
this price class. A major advantage of the SF-19 is that the base is entirely flat, a lot of coolers are only designed to be
used on tables but this model is very comfortable to use on your lap.
Here's a closeup of the rubber carrying handle, it makes it a lot easier to grab and transport a cooler this large. You can't
really see it on the picture, but Cooler Master also designed grooves in the rubber pieces on the rear of the cooler, they're
designed as a cable management system.
The plastic vent is easily removable and provides instant access to the two 140mm fans. Cooler Master doesn't share much
information about these fans, they are rated at 1200-2600RPM but I can't find any hard data about the airflow or noise.
A plastic fan grill is attached to the fans. The fans are secured to the plastic mesh by clicking them into place, and you
can slightly adjust the position of the fans to better accommodate your laptop.
The fans are connected to the cooler using regular 3-pin connectors, making it easy to replace them. Also interesting is that
there are a total of four 3-pin connectors, perhaps Cooler Master originally toyed with four 80mm fans before deciding to
place two 140mm models in this model.
