[QUOTE="Joutungwu, post: 1192583, member: 147600"] That's a nice review. (y) Apart from this, i guess the airflow could be optimised. The two case fans at the cpu side are in intake mode, the CPU fan is in pull mode and the cover case fan is in outtake mode. That's totallly correct so far and i would do the same here. Is there a dust filter at the cover fan? Only intake fans should have dust filters. Outtake fans don't need them, because instead of catching dust, they blow it away. All intake fans should have dust filters. Outtake fans only get performance reduction from dust filters. The case fan at the PSU side is in outake mode, where it should better be intake mode, because only then it supports the Palit GTX 1070 by providing cool air from the outside in the direction of the graphics card instead of working against the GPU fans as it is now. If you correct that, you will get overpressure inside the case, which is also good to keep the dust out. For example, Silverstone recommends the overpressure airflow concept for their HTPC cases. I read about it, when building an HTPC with [URL='http://www.silverstonetek.com/product.php?pid=241&area=en']Silverstone GD05B[/URL] and i assume this concept matches to your HTPC case, too. Silverstone also recommends graphics cards that "have a fan blowing exhaust air to the rear slot", which matches better to the overpressure airflow concept at all. Have a look at page 20 of this [URL='http://www.silverstonetek.com.tw/downloads/Manual/case/Multi-GD05-Manual.pdf']manual[/URL] where the differences of graphics card coolers are well explained by the pictures. The problem with that rear exhausting GPU coolers is a taller length dimension of the card, which, as you said, is not preferable in HTPC cases. [/QUOTE]
