From underneath on the inside, with the bezel still intact, you can spot the two pre-installed 140mm Nanoxia fans. You can also see the designated areas for the different size fans and rads that are listed. Additionally we also see some slotted areas for placement and/or movement front to back of the radiator and fans as well.
With the thickness of the top bezel at 1-5/8 inches, I am already thinking: rad attached; fans up top; followed by fans below for a push pull configuration. The slider pictured below is pushed to the fully opened position for optimal air flow and exhaust of hot air out the top of the case.
Let’s have a look up top with the bezel removed:
A simple tug at the slotted back side of the top bezel will release the eight tabs (four on each side) and remove the bezel with no problems. Just be sure to undo any cable connections before you start. After that, gently feed them from the backside of the motherboard tray and out the top as you are pulling them up through those areas.
There is a ton of real estate up top but it is mostly taken up by the mechanisms that control the air chimney’s top fans and pop-up I/O panel. All is not lost here as you can install up to six 120mm X 25mm fans to the radiator first and secure them from the inside underneath. As long as the radiator and fans together are not more than 89mm thick and the proper slotted holes are chosen, you should have no problems.
I took these two shots to show you just what’s going on under the top bezel along with a close up of the switch that will activate your three fans up top when the chimney is opened. With the cross members in three places as well as the rails on both sides, it literately leaves you with no options to place fans inside the top bezel. Off to the right and out of view are all the cables and connections for your top I/O panel.
Below is the switch that closes when the air chimney is opened, and turns on the fans when the rails move forward to raise the stacks on the two chimneys. Let’s move on to our installation.
