Fan is too noisy
-
There are 3 fans in my old desktop computer ie 2 fans to draw out the hot air and 1 CPU fan. The noise made by the fans are loud.
Are there any ways to reduce the noise level to a barely audible level ?
Thanks for any advice.

Hi Lee012lee,
Has your fans always been this noisy or are they getting more and more noisy recently?
Cheers.

You will get used to the noise after a while.
In fact, if the noise stops, you might find that something is missing.

Fans have always been loud.
I have even replaced the newer graphic card with an old graphic card without a fan ie the old graphic card that dissipates the heat with the aluminium heat sink/coil hoping that the computer will draw less power with the low end graphic card and hence less heat will be generated and the fans will not need to spin so fast and generate less noise. It does not work. The fans are still as loud.

You may try SpeedFan to reduce the fan speeds and hence reduce the noise level, but do note that if the fans are too slow, your CPU and other components may overheat.

Hi Lee,
If that is the case, I believe it will be hard to make the fans spin at a barely audible level, given that it is a natural thing for it to spin very loudly.
My suggestion is for you to transfer all the data you needed to a portable hardware, and change your entire CPU. You can try some of the computer hardware shops for a cheap 2nd-hand CPU.
Cheers.

Just tried downloading the software but on my laptop, it does not show any fans. Does this work on a laptop? My laptop fan seems to be having problems so i wonder its the software or my fan thats not working...

Can try putting 1-2 drops of oil into your fan, I used to do that to my old heatsink fan.
I used synthetic motor oil, it really reduces the friction.

Hi dkcx,
It is possible that your labtop's fan has melted partially/bent out of shape, or there is too much dust clogged inside. The former case is likely if it sounds like the fan is constantly hitting on something, and the latter case if there is weak air flow coming out from the labtop.
Cheers.

My guess is the latter but i dunno how to open up the laptop to clean or at least check the damn fan...Starting up can hear some wierd noises from the laptop and kanna fan error message a few times...
Stupid lenovo has too many screws and after unscrewing everything i still can't seem to open the back so i given up trying before i break something...

Now need check with the sch comp shop whether i can bring it there and ask them service or must i call Lenovo...
Only good thing is my laptop is not too hot i guess, 50 degrees not very high right?

Hi dkcx,
50 degree Celsius is generally still an acceptable temperature for a labtop, though it shouldn't get too much higher than that.
Cheers.

Should I buy the Intel CPU Atom N280 since it draws less power, will this make the fans' noise be reduced considerably ?
Thanks.

Hi Lee012lee,
Even if you are to change your CPU to one which draws less power, there is no definite 100% guarantee that the fans' noise will be reduced to a bare minimum. Instead, you may want to ask about the noise level first from the seller before purchasing a new CPU.
Cheers.

Hi
My refridgerator fan also super noisy, i suspect some bolts are loose
Shld i spend 100 bucks repairing it or get new one?

Hi laurence,
Do have a look here and see if you could fix it by yourself before spending money on getting a professional to fix it or getting a new one.

laptops usually don't display fan speeds.if you're using a Dell system, make sure you've enabled the DELL feature on speedfan.

1: check how the fans are connected. firstly, if the fans are connected to your motherboard via 3-pin or 4-pin fan connectors, you may use speedfan to try and lower the speed of the fans. if that doesn't work, boot into your motherboard's BIOS and see if you can lower the fan voltage from there. sometimes the motherboard defaults it at the 12V maximum, try lowering it to around 7V for the best blend of performance as well as noise level.2: if the fans connect via molex, there's no way to control the speed, as it's running off it's 12V max power. note how the pins are arranged in molex. there are 4 wires on the molex plug. the yellow wire is the 12V supply, right beside it is a black wire which is the grounding wire for the 12V supply. on the other side there will be a red wire. the red wire is for 5V, and the one next to it is it's grounding. if you notice, the wires leading to the fan motor will be soldered to the yellow and the black wire, meaning that it's on the 12v rails. your current connection looks like this.
from PSU: fan connector:
Red (5V) ----------------> Red (pass thru)
Black (5V GND) ------> Black (pass thru)
Black (12V GND) ----> Black (black wire leading to fan)
Yellow (12V) -----------> Yellow (red wire leading to fan.)here's a picture to show.
if you look carefully, you'll see how the fan is attached to the yellow and black i mentioned about.
now, you want to reduce the noise, and to do this you've got to slow the fan down.
ideally, you'll want it to run on just 5V.so you unplug the fan from the power supply...
and plug it back in the other way. so now it'll look like this:from PSU: fan connector:
Red (5V) ----------------> Yellow (red wire leading to fan.)
Black (5V GND) ------> Black (black wire leading to fan)
Black (12V GND) ----> Black (pass thru)
Yellow (12V) -----------> Red (pass thru)this will make it run on 5V, which will effectively silence your fans, but you're sacrificing some vital airflow for this silence.
there's another way that you could squeeze 7V out of the fans, but this modification is tricky, and stresses your power supply so i won't say how to perform it here.
3: turn your pc off and remove the fan. clean out all the grime on the fan if it's really dirty. give the fan a slight spin with your finger. does it spin freely and smoothly? if not, this means the fan bearings are dry.
on the motor side of the fan (where the wires enter) there will be a sticker over the hub. peel it off to reveal the rubber cap over the bearing - keep the sticker as you'll need it still. remove the rubber cap, and drip some oil into it. best choice would be mineral oil, but motor oil as well as regular singer oil will suffice. don't use WD40, since it will just dry up the bearings again. don't fill the oil well to it's brim - the oil will spill out when the fan turns or when you replace the cap. replace the rubber cap carefully and place the sticker over it again. let the fan sit sticker side up for about an hour, then plug the fan in again and run it for awhile to let the oil lubricate the bearings.
-
don't forget that your computer's power supply also has a fan - check if it's the PSU fan that's making the racket
-
if you don't want to oil the fans, or are afraid to put oils near electronics, PM me and i can sell you some fans on the cheap. don't forget to take down your fan's measurements as well.

I'm afraid it doesn't control fans on a laptop.

You also very noisy lei, how to fix?

this is true for most modern laptops. however, some old laptops have had their fan speeds controlled by speedfan, but that's a rarity.enabling the DELL support (for both laptops as well as desktops from DELL) only allows you to view the current fan speed(s), but not control the fan speed.
