Dust can create problems with overheating of components, causing early failures. Also check out the power supply fan which can be seen on the back of the case.

Stop each fan one by one while the system is on by a process of elimination you should be able to figure out which one is causing the noise. It should be ok to stop each fan for a few seconds. So you will come to know which fan is louder.

The fan noise is probably coming from the CPU fan. You can do a search for silent fans or low noise fans and replace it if you are careful. the CPU and PSU are always on the lowest setting (cpu <2000rpm) to make the computer as close to silent.
