GPU Airbox/Support
Description
This thing is a GPU support, but instead of just being a bracket it also forms a duct to bring in cool air from the back of the case. I am posting this thing more so to share my general concept with others, with a very low expectation that the actual stl's would be of use to anyone. I designed this for my Corsair iCue 4000 case w/ GTX1650, but maybe it can fit other hardware? Before when I was playing FS2020 (1440/ultra/hdr), the gpu would quickly hit 75C (89C hotspot) and throttle itself the whole time (yes, with afterburner making more fan noise too). With this airbox installed, same ambient etc, the gpu now tops out at 68C (81C hotspot), and the throttling is pretty much gone altogether (shame that has not made me a better armchair pilot though ;) ). That is a major improvement for something that required no extra fans/noise... and took a few seconds to install. The bottom/top is just a tight friction fit, and the bottom is secured with a pair of strong magnets to the PSU shroud on the bottom. Works well enough, and if needed the friction fit can be secured for transport with a pair of tapered tap screws through the seam area. I had such good results with it that I plan on chasing some higher hanging fruit as far as optimizing the design. I like how it looks, but there is room for me to increase the intake area quite a bit. I had to angle the bottom part to clear the mobo io headers on the bottom. I kept that feature simple for testing, but it does reduce intake area. The box can be reshaped wider near the back (where there are no wires to worry about) to swallow up all the area available in the expansion slot cover plates. There's also the (now useless) vertical mount gpu vent holes adjacent to the side panel, which can also be swallowed up for a lot more air intake area (though my printer bed may be too small to make this). With the cover plate area fully covered, then I could remove the cover plates to reduce restrictions more (corsair vented cover plates ain't half bad though). With all that extra intake, I also plan to integrate dust filtration inside the box itself (making use of the massive area available there). I think with those mods airflow will be even better... maybe get another 2-3C lower. I will need that overhead when summer comes I think. Anyhow, if you so happen to have an icue 4k case and gtx1650 (perhaps others... idk), then this may be something you can just print and try. If not, and you end up making your own gpu airbox design, I'd love to see what you came up with and what results you got... please share in the comments.
