The Top, Bottom, and Rear Panels
The top panel of the Fractal Design Define XL is plain, and one may wrongly assume that this case doesn’t have a top fan. One of the highlights of the reviewed case is the presence of an internal top fan, which we will talk more about on the next page.
The reviewed case has two USB 2.0 ports, two USB 3.0 ports, and the traditional audio jacks, located at the front part of the top panel.
The bottom panel has an air filter for the power supply fan, which is removable by sliding it from the rear panel.
The rear panel and the interior of the Fractal Design Define XL are painted black.
On the Fractal Design Define XL, the power supply is installed at the bottom of the case.
The case comes with a 140 mm fan installed on its rear panel. No technical specifications for this fan are available. It uses a standard three-pin fan power connector. It can be installed on the single-channel, analog fan speed controller that comes with the case.
This case has only seven expansion slots, which may be a drawback for users looking for a case that can fit a dual-slot video card in the left-most motherboard slot. All slot covers are vented. An eighth slot is available above the regular slots and can be used for installing the included fan speed controller.
The Fractal Design Define XL has two holes using rubber covers for hoses of liquid cooling solutions. These holes are 0.7” (17 mm) in diameter.
The single-channel, analog fan speed controller that comes with the case can be seen in Figure 13. It allows the installation of three fans, so you can connect the three fans that come with the case on it. Since it is a single-channel controller, the speed of all the fans will change simultaneously as you move the controller’s knob.
Let’s now take a look inside the Fractal Design Define XL.
