PSU swaps are pretty easy. But if you aren't familiar with doing it, or don't want to risk it for some reason then replacing that lower end PSU is a good idea. A quality 450W will run your 560TI just fine. (Artic cool isn't known for quality units. Think Antec, Corsair, Seasonic, XFX, etc.) Make sure it has the two PCIe 6pin plugs your card needs. Should be around $50 online.

Otherwise, as Ram said stop the fan and make sure the noise goes away. Open the PSU and unscrew the fan. screw in the new one. You might need to rob the power connector from the old fan. If you open it before hand you can see how it connects. If it solders to the PCB then you need to either replace the unit as a whole, or clip the wires near the fan and splice in the new fans power wires. If your eyes glazed over all that, then just replace the unit.

Edited for spelling.

thank you very much i can change the power supply no problem just never changed the fan before. is it safe to stop the fan with every think turned on

 
For a system using a single GeForce GTX 560 Ti graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The XFX Core Edition Pro Series 550W (P1-550S-XXB9) power supply unit, with its maximum combined +12 Volt continuous current rating of 44 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 560 Ti graphics card.

You only need to stop the fan for a few seconds to see if the noise stops too. The fan should restart itself. If it doesn't then it's definitely the fan.

Stopping any of the fans for a few seconds will have no perceivable affect on your computer.

Fans make two types of noises. If the blades are hitting something it will sound like a very rapid ticking. When bearings go bad they make a high pitched whining noise. You didn't mention any of these other symptoms in your original post. I STRONGLY suggest you find a known good PSU to substitute with yours temporarily. That way you can see if the symptoms disappear. You can probably get by with a smaller PSU for test purposes. You must diagnose first.
