They do sell portable swamp coolers. They are about the size of a night stand. You fill with water and the air blown out is cold. Not cheap, but disturbs the air less than a fan.
We moved to a new building and I was the ranking person of my level so I got first choice of an office. I picked the perfect office. Not too many many windows, east side of the building. I was happy. Then I got a slight promotion and had to move to a bigger office. I lost the coin toss and got the SW side of the building with 5 huge windows. I was hot even thinking about it. I complained constantly that my office was too hot. This went on for months. One day I went over to the other side of the office (it was like a horseshoe with the offices on the outside and the support staff in the center) and it was like a meat locker!
It was my old office. Every time I called to have them turn down the a/c the maintenance guys did. They looked on the office blue prints, saw my name on that office and turn the a/c down another degree. It was about 60 in that office by the time we figured it out.
