Made a little cpu fan duct mod for the A4-SFX. Compatible with the Noctua NH-L9a-AM4 CPU cooler that I believe most of us are using. It is 3D printed in PLA, doesnt use support material (for the printer i used) and just snaps on to the top of the fan, so no installation tools or fasteners required.This duct fills the gap between the CPU fan and the case side panel so that the CPU is only drawing external air for its intake. I made it flare outwards so that the intake cross sectional area is not restricted at all by the side panel's perforations. I'm noting about 3C lower temps running the timespy CPU test. But considering how much the fan throttles up when it hits 80C, the temp delta would be a lot greater if the CPU fan was set to constant speed. Because my EVGA 3060ti never gets very loud, this has noticeably lowered my PC's fan noise during regular use. Could look in to sharing the 3D file if people here are interested. Cheers
