Power supply is making loud grinding noise

I've never bought a power supply before, so I'm lost. Here's the parts I think you need to know, I bought this computer from cyberpower in 2007, let me know if this isn't enough info:

CoolerMaster Unit 600 Watts eXtreme Power - SLI Supports
(Quad-Core FSB1333) EVGA nForce 680i SLI Chipset LGA775 FSB1333 DDR2 Mainboard
CPU: (Sckt775)Intel(R) Core(TM) 2 Duo E6850 CPU @ 3.00GHz 1333FSB 4MB L2 Cache 64-bit
NVIDIA GeForce 8800 GTS 320MB 16X PCI Express

Total of 6 fans, only the ones on the graphic card, CPU, and power supply works. But the power supply fan makes really loud grinding noises and the graphic card above it gets extremely hot. I need to somehow connect the other fans since it seems cyberpower never fully installed them.

Thank you for any help!

  1. I heard that CM units make loud sounds or grinding noises when they reach the end of their lifetime.

    Its possible to open a PSU and replace a fan, but should only be done if you REALLY know what your doing. Otherwise you could kill yourself, no joke. A better option might be to pay someone to do it for you, or perhaps just buy a new unit. CM isn't the best out there.
