I've got the same tent as you TB and I have the exact same dilemma with the fan. I've been using an oscillating stand fan and the base just takes up too much space. It would be ideal if you could hang an oscillating fan from the top in one of the corners of the tent, something like in my illustration below. Two would be even better I suppose.... obviously the main concern will be allowing the fan to rotate freely but I reckon with a bit of DIY or just securing the fans smartly to the top, and we could have the fan issue solved...
