Good Box Fan With High RPM to Keep My Computer Cool?

Hey guys

I just got a Corsair 1000D case and didn't realize until I was done building it that it does not come with any fans. I did just order all of the fans but it's going to take like a month to get here so for the time being I'm running my computer and cooling it with just a regular box fan. My regular box fan is basically just a $40 walmart box fan so it's nothing special. Does anyone know of any good high tech or high rpm box fans that I could use to cool my pc right now for the time being until the official fans come it?
