Most cheap systems only have 2 fans, one in the Power Supply (PSU) and
one on top of the CPU heatsink.. If you get a plastic drinking straw or roll
up a narrow roll of paper you can poke it into the rear grill on the PSU and
stall the fan, if the noise stops, you need a replacement PSU, if noise
continues, you need to open the system and check the fan on the CPU
heatsink. See other reply for advice on replacement.
