Hi @claire

To avoid fan noise :-

Method : Make sure you clean your computer with blower every 3 months at-least.

To Repair fan noise: -

Method 1: check is your fan have suspension spring. If yes, check is the spring is not rusted / in dirt. You can replace the spring if got rusted. You can clean the fan with a blower (safest method) or painting brash (should not disturb the circuit).

Method 2: Their is no other way, replace the fan with exactly same brand and modal to avoid complication.

your PC could have lot's dust, causing the fans to kick in faster than they normally would.

I've tried using a program called SMC Fan Control for PC which can regulate when your fan kicks in, and how fast it would be etc. Try using that.

Turn off your computer. Unplug the power cord. Open your desktop PC. Use a can of compressed air to blow out dirt and dust that accumulates over time, paying particular attention to the fans on the motherboard, the case vent and perhaps the fan inside the tower's ATX power supply. Close your PC. Plug in power cord. Power up your PC to test fans' volume levels. If cleaning has done the trick and reduced the noise, then your problem is resolved.

If not, you may have a damaged fan... perhaps the bearings have worn out... or maybe something came into contact with a fan blade which caused the blade to be misshapen and resulting in an imbalance... It can be hard to tell what exactly is wrong with your PC's fans, but if cleaning the PC and fans doesn't fix it, just replace the fan(s).

Normally, system fans will rev up and down based on temperature readings as monitored by the system. Unusually loud fan noise can indicate a failing piece of replaceable hardware (such as the fan), but unusually loud noise from a system fan can be the result of the system trying futilely to cool the CPU on the motherboard; this may happen when the CPU is being strained with too many ongoing operations.

Consult your PC manufacturer's website for desktop model-specific fan specs, including the fan's wired connection to the motherboard (2 wire, 3 wire, etc.), and note all the fan's dimensional measurements to ensure that a replacement fits perfectly and is wholly compatible.

There are any number of places online (newegg.com, tigerdirect.com, amazon.com, ebay.com, etc.) to purchase a new fan, so you might want to shop around for the best price for the fan model you need.

If you have to order a new fan, replacing the old one is relatively easy. In some cases, you are likely to only need a basic Phillips screwdriver. Be sure you power your PC down, and remove the power cord from the electrical outlet before opening the case of your tower. There may be four screws to remove (one at each corner of the fan), or there may also be a spring clamp that locks the fan down to the motherboard. That aside, there is likely one other thing to remove, and that is the fan's wire leads (and its connector) to where it connects onto the motherboard. Of all the things to repair, a fan's replacement is only normally no more difficult than installing RAM cards.

Run the Troubleshooting server system boot issues wizard to identify and isolate problems with the setup or configuration of the system.

Download the latest BIOS/firmware update package. Applying or reapplying the latest firmware quiets fans more than half the time.

If only a single power supply is installed in a dual power supply system, check that the power supply is installed in the first power supply bay.

Make sure the chassis intrusion switch is connected properly, if your system has one, and the top cover is firmly seated.

Check the fan cables and headers on the server board against the System Integration and Service Guide for current systems or the Quick Start Guide for older systems. Fan cables can potentially be plugged into the wrong header, causing the fans to run faster than they should. For more advanced users, complete fan header and pinout information can be found in the Technical Product Specification for your system.

Set your BIOS for Acoustic mode. This reduces the power used by the system and reduces the noise.

If none of the above solves the issue, download the BIOS and Firmware Update, Configuration Utilities for current boards and systems, or download the System Event Log (SEL) Viewer for older boards and systems and check the SEL for errors. The SEL may show where the problem is.

Use the troubleshooting wizard for resolving high fan noise issues

Cannot believe somebody has not suggested this first unreal! You need to earth yourself b4 u start seeking out what the problem is inside ur computer. To do this.. with the computer off..with one hand grab the main power cord..and with the other place hand on main chasis of computer..with 2 points of contact at the same time..this is to prevent static doing more damage! once u done this then u can proceed to dive in so to speak! Also far as compressed air goes..sometimes can to more damage than u think..We use a electric air pump..on all our clients computers..basically we control the airflow..which is what u need a 220-240vac 50hz.130w is sufficent to accomplsih the task!

Most likely you'll have to clean it, most likely it's dusty. There are products for it, but depending on your computer, you might need to open it to reach the fan. I do suggest to clean it, though, or you might be putting your computer in danger.
