CPU Fan. I recently opened up the tower case on my Gateway 500GR PC desktop to clean up the dust off. I also did take outthe fans and dusted them then put them back. However, the CPU fan sounds much louder now, like its spinning too fast than usual or something like tha. What could I have done wrong.. I checked it again and looks like I put it back correctly.

    I have the exact same problem. Mine is a Packard Bell PC. Normally when the PC is first started the fan runs at full speed for a few seconds and then slows to a normal speed and is very quiet. Since I tool the fan out and cleaned off the dust it is running at full speed all the while which is fairly noisy too. The noise is due to the speed of the fan. Could I have damaged the fan while cleaning it and putting it back in? Would a new fan solve this problem?

    Fan runs constantly. Runs very loud.

    I have the same exact problem. I've never had a problem with my computer's fans being loud until I recently removed them to clean the dust out. Ever since I reattached them they have been EXTREMELY loud. But only occasionally. It only happens when I'm doing something processor intensive.

Make Sure your thermal compound is properly placed, check the temp of your CPU. CPU might be overheating due to destroyed layer of compound and therefore Fans run faster...

You cleaned the dust off, therefore it will run faster, and louder.
Also, you probably didn't place it in right or tight enough and so it vibrates against something.

Don't worry, but make sure that if you notice that it gets very quiet all of a sudden your fan may have failed and u should save all work and shut down immediately. Not very likely.
But fans are usually easy to replace; you could buy fans for 15$ and all you have to do is place them on the case and plug them in. There are instructions all over the internet.

    For certain temp-sensing fans, if there are two short wires and they are separate but seem to touch each other they may cause the sensor to think that it is extraordinarily hot inside.

  • Anonymous Jan 06, 2008

    to mickyboy73, well it was a fan problem so replacing the fan would have fixed it...

    Well hopefully you won't have any more fan trouble for a long time after doing all of that.

MBA Runner has a Gateway 500GR whose fan ran too loud and constantly. I simply removed the cpu fan and heatsync then cleaned out excessive dust. That solved the problem. Heatsync is bolted to the mother board by a bracket. Should the bracket shift, you will need to take out the mother board to reattach the heatsync.

Ok, what I did to fix this was removed the fan and heatsink. Put some fresh thermal paste on the heatsink and then replaced just the actual fan and now it runs much quieter than before.

I am monitoring the fan speed and CPU temp and all is fine ;-)

I could have replaced the heatsink and fan I guess but I wanted to know what was causing the problem.

New fan and some thermal paste and it's all good again.

Thanks to all for your help and I hope this may help others too.

DONT EVER PUT A COMPUTER ON ITS SIDE UNLESS IT IS NOT RUNNING!!!!!!!!! If the fan was a thermal sensing fan then the sensor might have got bent. If both wires on the thermal sensor are touching, It will run at full speed. This will make it quite a bit louder.

Well a fan that is 4.5 years old can really be dry. You might check to see if it can be lubricated by pulling up the sticker on the fan. Sometimes you can add a drop of oil on the bearing and stop the noise and increase the life of the fan.

Some times a fan will tilt just slightly off its axis. Even a small difference can cause the plasdes of the fan to touch againts the casing and be the source of increased noice. Try setting the PC on its side. Does the noise level change? Fans are a part of a PC that are almost always in constant motion, and thus are subject to faster degradation than other PC components. You should be able to easily replace the fan with a new one to eliminate the noise.

SOURCE: Gateway 831GM Eratic Fan Noise

Hi,

This can be caused by several things:

1. Bad temp sensor
2. Bad voltage, but that will usually cause the whole system to restart
3. Too low maximum temp setting inside the chassis(setting is in bios), often denote as max case temp.

One way to bypass the problem is rig the fan to a molex adapter with a variable voltage molex to 2/3/4pin fan connector and adjust the speed to the maximum quiet setting.

The 831's did run a bit warm so if the case temp setting is set to low it will fluxuate quite a bit. Try adjusting the max case temp up around 50c just to see if that does it, if it does either use the variable voltage dial solution or add a second case fan that's always on, prefferably a low RPM running direct off molex so it will reduce the average temp and therby the need of the monitored case fan to rev up.

Cpu temperature error

Turn off PC, Unplug PC from power. Open PC case. Examine all fans including CPU fan and heatsink. clean the fans and heatsink. With case open but everything inside connected properly, Plug pc back in. Power up the PC and check that all fans are running. If not replace fan that is not running. Place PC in a well ventilated area when operating. I use a new small paintbrush for cleaning dust from inside of PC.

Clean heat sink

Yes you can, remove the cover off the desktop computer to get access to the fan and heat sink over the CPU.
Use a stiff brush to loosen the dust off the fan and heat sink and vacuum the dust off the fan and heat sink. You may need to use a can of compressed air to blow the dust off the fan and heat sink then vacuum the dust out.

My NB temperature over heats really easy. What can I do to fix this?

Your computer is overheating. Three causes of overheating are:
1) Dust - Dust inside the computer, dust clogging the fans, dust clogging the vents, dust around the cpu and heat sink. Remedy - Open the case and blow out the dust with a can of compressed air.

2). A fan is not working. Remedy Replace the fan. There are two so find out which one is not working. One is inside the Power Supply where the power cord plugs in and the other one sits on top of the CPU and Heat Sink on the motherboard.

3) The Thermal Paste around the CPU and Heat Sink has dried up or is too thin to keep the unit cool. Remove the Fan, CPU and Heat Sink and apply a fresh coat of Thermal Paste.

Cpu overheats

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

When i turn on my dell dim 8400 the fan races very fast i have to power down and start back up sometimes it takes 2 or three times then starts to work but after awhile it freezes up or if i wiggle the...

Normally, when the fan gets loud and races, it means that the CPU is getting too hot. The normal fault is that the case and ventilation block on the CPU is full of dust.

Disconnect the tower and take it outside or somewhere where a bit of a mess isn't a problem. Open the tower and look inside. Is it full of dust?

Using a dry soft bristle paint brush, CAREFULLY liberate any dust and fluff, if you have a hoover, brush to the hoover to remove dust.

The CPU is under a big metal blob with a fan on the top, Underneath the fan there are a load of ventilation duct in a metal block. See if you can clean them out, compressed air in a can is a good way. In conjunction with the brush.

Check all the vents and fans are clear of dust, including the PSU.

Once done, try it again, does it still race / lockup / close down.

If so, then you may need to renew the heat dispersal grease which is placed between the CPU and the Heat sink (Vented metal block under the fan).

The best place to find how to do that is look on Youtube for CPU changing / fitting / upgrading.

It will not turn on

Assuming all leads are in place, mains plug fuse is good.

Remove all power sources and leave for 5 minutes, allows all stored energy to dissipate.

Take the cover off the tower and check the fans, vents and the cpu fan.

if they're full of dust and fluff, clean them out.

Don't take the heat sink block/plat off the CPU, just unscrew the fan and clear from there.

Put it back together and try again, if this fails, then there's a component failure, possibly the PSU
power supply unit. Unless you have someway of testing it, you need someone who has.

My computer turns off and when restarted says it was shut down due to thermal over heat. Both fans are working.

I would take the unit outside and give it a thorough cleaning, lots of dust accumulates on the cpu fan and heatsink ;)
Afterwards if its working stable I would update the bios firmware, just make sure it doesn't overheat during the upgrade, it's critical!

More than likely your computer needs a good dusting:

  1. Unplug the computer
  2. Take it outside
  3. Open up the case
  4. Spray all the dust out.
  5. Plug everything back.
That should take care of your problems. Let me know if it doesn't.
