Phanteks Eclipse Series Bottom HDD tray / PSU cooling question

[pdubz]

Has anyone attempted to direct air to the bottom enclosed section of the Phantek Eclipse Silent P400s?

I've been running my system with my media and archived storage on 2 spinning HDD's as well as a Seasonic Snow Silent (fan only runs when using lots of power, ie Gaming/transcoding/editing) in the bottom enclosed space which has no fans there. I'm not really sure how the test benches have rated the heat down there, but I think i'd feel safer knowing my large expensive HDD's are properly cooled. All this is of course until I can afford a NAS and this problem will be moot.

Here is my build:

Intel Core i7-6700k 8M Skylake Quad-Core 4.0 GHz (OC'ed to 4.8 stable ASUS EZ Tuning BIOS)
AsusROG Maximu VIII Ranger Z170
G.Skill Ripjaws V Series 32GB (2 x 16GB) DDR4 3200
Samsung 950 PRO M.2 2280 512GB
Corsair Force GS 240GB SSD
Seagate Barracuda Green 2TB 5900RPM SATA 6Gb/s
WD Red 3TB NAS 5400RPM SATA 6Gb/s
Corsair Hydro Series H115i Extreme 280mm
EVGA GeForce GTX 1070 FTW Hybrid 8GB GDDR5
SeaSonic Snow Silent 750W
