Do you know a way to increase the Speed of the computer Fans

Dirt and Dust build up over time, its worse if you smoke around your computer.
Your fans may be slow due to accumulated debris.

Pop the case and give it a good cleaning. Make sure you pay attention to the fan shafts, blades, and housing.

A little light oil or silicone spary in the bearing will help too.

I did this on my previous machine and it made a world of difference.

OK I see you are referring to case fans. I also see you have plugged them into the dedicated "fan" connector comming from your power supply. I think these are usually full voltage connectors. Those fans also look clean to me so I doubt they are being slowed down by a lot of dirt. Most case fans that claim to be "quiet" on the package or advertising run purposely at low speed.

My favorite fan is the Thermaltake MadDog MD-TTF-DB-A1357. It's a high speed (4800 RPM) fan with both pot and thermal sensor speed controls. I attach the sensors to my Video card and chipset heat sink. As the demand on my system increases, the fans speed up and they go much faster than typical fans. When I'm at the desktop doing 2D stuf, can't even hear them. When running SH4 they howl. Been using this technique for three years with no heat failure even when over-clocking. Of course my CPU and Vid card have a lot more cooling capacity than it looks in your pic where you have a standard CPU cooler that came with the CPU.

I see one of ur problems, the fans are blowing air thru SMALL holes in the case. If you cut out a hole the same size as your fans airflow, 140mm, you'd see an increase in fan speed an air flow. I did this to my case an there's a vary noticable differeance.... It cuts done on noise too, the fans not working so hard..

You have THREE 140mm fans at 1400rpms in your case... and you have a problem with airflow? I think not! Is something overheating in your computer? Because that would indicate a poor setup of something in your case... a bad heatsink, I notice you have a stock CPU cooler and passive video card? Is these overheating?

Zalman coolers for the CPU and card. You can't do better.

I've a Thermalright on my 8800GTX, it used to run 75C idle / 95C load on the stock cooling, now it runs 50C idle / 75C load with the Thermalright cooler. Amazing difference!
