My advice would be to switch the pc off and go and chill out in a room you can put the aircon on.. Failing that..
a cheap rotary fan on one side of you, pointing towards the window might help a bit.. But you've also got to think about how this heat will affect your pc aswell, as the fans in it will be pulling in hot air from outside to cool it down and then they'd speed up to counter this problem causing more noise...
Once you get the fan, switch it on to high, and go right near it and say "Luke.. I am your father".... Oh i'm not immature at all, i do it all the time to my kids, and they just give me dirty looks!!!
