Two ways come immediately to mind...

If the fan is plugged into the motherboard, check the bios to see if you can turn up the fan speed.

Second way would be to get a fan controller that would allow you to control the speed of the fan. In my experience, many fans run a range of speeds, with a default speed. A good fan controller woudl allow you to turn up the speed of the fan to it's maximum. I use the Cooler Master CoolDrive IV when I'm testing fans to control the speed settings.

It will take more voltage to make it go faster and if you put more voltage to it will likely fry the fan. I would suggest replacing the fan with a faster rpm fan if you need more cooling.

Finding a 25cm replacement fan might not be the easiest thing, but like dadx2mj says, I wouldn't recommend making it go faster.

Maybe Modulok can confirm this, but I would guess it is running at full speed, and that it just isn't a very fast full speed.

Are you having heat issues on your system?

Have you tried the fan blowing in both directions? (I know it is reversible).

How about populating the 120mm fan locations? (I know it doesn't come with anything but the 25cm fan).

well, according to many temp's i've seen on people's pcs, my temps are kind of fine.
gpu 50-60, cpu 47-55

but it is still hot, i can feel it with my body and that annoys.

and the fan is only connected to the PSU.
and the two direction thing is kinda cool... but it doesn't really help.

ok, the 25cm fan with this case is pretty good at cooling. I believe it runs only at 800rpm. (EDIT: 650rpm, 17dBA, 90cfm)
It connects via molex direct to the PSU, so fan controlling is out of the question.

Try to do a quick benchmark with the fan off, then blowing into the case, then as an exhaust. The fan helps cooling greatly even at low RPM.
