Your fan needs to stay on to keep the board and devices cool but if it is making noise you may want to try to clean it with canned air and if that doews not make it quieter than you may want to get a new fan

Fan slow down and them high speed


change the fan ASAP, since the zooming noise and the slow performance will affect even the processor and you might end up replacing the processor as well if it persists. So get the fan ASAP and problem will be solved.

You may try to remove the fan, clean it up. Also try to remove the processor heat sink (clean the thermal paste), reseat the processor, put a little thermal paste, that assemble it back. Before you do this, ground your self first(the easier way, hold any metal).


If this can't help,check the capacitor at your MoBo and if you found any unusual look like, it mean you need a new MoBo.

Compaq Presario SR2150NX doesn't turn on. Front panel green light turns on but nothing else happens (no fans, no boot, no noise, nothing) Please advice


On the back of the Power Supply there should be a Green LED, When you power it on if it is flashing, this means that the Power Supply is dead and you need to replace it.

Suggest you change out the power supply if this indeed is the fan noise.

Why?

1) Because it may not be a cracked mount for the fan casing. It could be the fan bearings are bad, allowing the fan blade center hub, to rub.
This would mean the fan is on it's way out, and you sure don't want a PSU without a fan!
(Will burn up in a matter of hours)

2) It is Not advisable to open up a PSU!

Inside are Electrolytic Capacitors. They are used in the Input stage as Filters for the incoming AC electricity.

They are used in the Output stage for the rectified DC electricity the power supply rectifier bridge converted.

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Even after unplugged from power, Electrolytic Capacitors can hold a charge for Weeks, sometimes Months!

If your fingers create a circuit path with the terminals of any capacitor, the stored charge could be released to YOU!

If your fingers complete a circuit that one, or more capacitors are in, the stored charge could be released to YOU!

Bad shock to Fatal!

Replacement is the best advice.
Be safe, Live long.

[Your PSU is an ATX style of PSU.
90% of personal computers out there, use this style of PSU.
It is a common style.

One of my fans has started making noise, how much time do i have to replace it? Am I right in thinking that it making noise that it needs to be replaced?


fan noises are usually caused by worn out fans. but can be also caused by IDE/power cables hitting the fan blades. you will have to open up the computer to see where the noise comes from.

if it is a faulty fan, replace it sooner than later as it will get louder and louder. then stop making noise all together when the fan fails.

Acer aspire4920 makes loud noise at start up


This could be caused by the harddrive. There might be a bad bearing or something. Please backup all your data. You will probably have to replace the hard drive sooner or later.

Noisy system fan


Here are a couple things to check.

  1. Are there other fans (other than the one you replaced) in the system? Many times, even with systems that use one main fan to cool the CPU and case, there can still be a fan within the power supply. There's a good chance that the power supply fan is the noisemaker. Also check for a fan on the video card.
  2. Check to make sure there are no wires or debris that could be lying against the fan blades.
My guess is #1 is the culprit.

PC Noise Problem


the noise will be excessive dust on the heatsink fan or the extractor fan, gently hoover off the dust, if after that the noise continues the bearings in the fan are failing and a replacement will be required.
