I have really noisy fan

[Eric Kithaka]

One day my pc wouldn't boot my OS, so I opened it up and reseated the fans, HDDs & the RAMs. I was however careful not to touch the capacitors and resistors and all the pretty stuff you find on a typical motherboard.

Re-seating fixed the booting problem. However, ever since my fan's been really noisy.

I have tried oiling the fan, dusting the CPU and nothing seems to work. I need help

My PC's a HP desktop, tower type

Is this a CPU fan or case fan we are talking about? Is the fan a standard 80mm, 120mm, etc... design? If it is a standard design, you can purchase a replacement from several locations. If you are not sure you can measure the fan frame width. If it is the CPU fan you may want to get a 4-pin fan.

The 4-pin uses PWM signaling to control the fans RPM depending on the motherboard temperature sensor readings. While the third pin is used for the fans RPM sensor, without a 4-pin PWM fan it would spin full speed.
