I replaced the original tempered glass front panel of the case with this hex pattern front panel. Brought my CPU temperature down by several degrees (Up to 15°C in some cases). To replace the glas the front panel needs to be pulled off. I Also removed the top cover of the case which made the process easier. After the frontpanel is out of the way the glas can be removed by unscrewing the holder on the inside. Note that there are 2 very small screws which are easily overlooked.
