Hi everyone, My PC at the moment looks like this: https://imgur.com/a/ynvkPy3, with the fans pushing air out of the bottom I'd like to build some sort of shroud that comes from the fans, up around the sides of the GPU - helping to ensure that all the air that the fans are pumping out is pulled through the heatsink of the GPU. I had thought of 3D-printing something, but I don't really have the skill with the CAD tools, nor the time or inclination to learn at the moment. Can anyone recommend me some sort of sheet material that is soft enough to be relatively easy to handle, but hard enough to not flap around, and not too ugly? I had thought of a thick piece of cardboard or some thin perspex sheeting, but perhaps I'm forgetting something? I'd love a recommendation. Note that I live in a flat (so few tools) any my DIY skills are *very much* minimal compared to the modding crowd on here! Bending hard plastic with a heat gun, for example, is probably a bit too much. So please keep it simple for little old me Thanks for the help!
