Yo dude, definitely nothing to laugh at when they're spinning over a gorgeous forest of solid chunkness! Looks brilliant inside that tent!
My only 2 cents of tips i had to give, was firstly you can also hang those muffin/computer fans from tents top bar with gardeners wire or twine through the corners of fan body and just loop the power cord round tent top bars as back-up grip - plus you could do either; (a) put a separate wire loop through each of the fans 2 top corners so it stays hanging the way it is now and it minimises spin but still keeps it swinging nicely or, (b) you could put a separate wire loop through each of the fans 4 corners and then when those 4 are tied round top bar it would face downwards and blow direct down onto canopy.
Second thing I've seen done with those computer fans to aid circulation was if your tent has bottom intake vent holes/tunnels, these fans usually fit quite snugly just inside, and if you can squeeze/seal one in to a bottom intake hole then they do draw in alot more fresh air compared to the hole just being open & passive, plus it's a breeze coming in below canopy level. A simple cut-out cardboard bracket or jacket can be taped round the outside of the fan if it's too small to stand up in & seal the vent hole on it's own.
It is abit of a DiY option, though I've seen some people who do 1 in every bottom hole available and swear by it. Though if your tent only has flat/flush panel vents at bottom it sadly doesn't work so well - they need a sort of hole/mini-tunnel to sit within.
Plus as long as your little computer fan is half decent spec, it does also allow the option to attach some basic filter mesh to outside front of all bottom intakes, which can then help lower the levels of dust, bugs, pollen, etc that can be blown in through the bottom - your fans could easily still suck in good air intake through say a pair of tights, a thin cotton t-shirt, coffee filter paper, etc.
Hope it helps anyway dude!
