The heat sink may be clogged with dust and ifthe BIOS temperature sensor controls the fan speed then it may be compensatingfor the reduced cooling by the dust build-up.
If you are not using your laptop on a flat surface, it may beobstructing the cooling vents on the bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem

My PC's Fan has a loud humming sound every time I boot up PC, how do I fix that?


Hi.

As Dean said, if the humming noise is always present even with the fan spinning at low RPM, replace it. If it's only loud when booting it might be normal ; some computer's BIOS spin the fan very fast when booting and when the Operating system or preset parameters take over, they gradually lower the speed. By the way, unplug the fans one at a time to find which one is causing the noise. If it is a case fan they cost only a few bucks, if it is the CPU fan it is a bit more expensive but aftermarket cooler can be found for around 20$. If you need to replace the CPU cooler, make sure you clean the old thermal paste and apply some fresh one. For a tutorial how Youtube is your best friends ;)

Really need more information, but my guess is dirty fan. If fan is blocked by dust, it may make noise and may run at high speed all the time because the CPU is overheating. If CPU gets hot enough, the laptop will shut itself down without warning. If dust is the problem, get some canned air. Before blowing into the air vents, try to spot where the CPU fan is and gently insert a toothpick to block the fan and prevent it from turning. A long blast of compressed air can spin the fan too fast and burn out its delicate bearings. Blow air from underneath and also from the side vent until air blows clear. In some bad cases of dust, the bottom or top cover must be removed to get it all out.

HP Compaq 6200 Pro Microtower XL504AV - doesn't boot


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with 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 sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Won't start but CPU fan vibrates but will not go full blast. Intermittant


It appears you have a faulty CPU fan and it is causing the CPU to overheat and shut down.
I suggest you replace the CPU fan. remove any dust from the heatsink and put new heatsink compound on the CPU/heatsink.

When I plug the unit into power, the CPU fan runs very fast but no boot, and then when I press power on the fan slows down and the PC boots normally. It shuts down in about 30 minutes with no sign of...


Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

It is possible that the fan is making the noise when it goes to fast speed as the cpu gets hotter, it could be a sign that it is starting to go and will stop running at some point, or it could be the hard drive as well, you can vacume out the inside of the machine as well as the fan and see if that resolves your problem. You also may want to order a new fan before that one stops running. I hope this helped. Good luck and have a fantastic day.

One day when i went to play my xbox i turned it on. It made a weird noise it had never made before. Then i realized my TV had no picture or sound, my controller won't connect and the usb ports are also...


It could be a couple different things , the cpu/vga fan , or the dvd drive are the two most common . If you can tell wich is causing the noise that helps a lot . If it's the fan , I would get a can of compressed air A.S.A.P. , more than likely if this fixes it , it will only be temporary . In the case of the fan making noise it's normally about to die or has some sort of blockage ( either way you don't want to even risk running your system without having it repaired / replaced ) . If you have to open up the Xbox 360 it's not a bad idea to put Arctic Silver #5 on both the CPU / VGA then replace the Heatsinks ( minus the horrible X-Clamps , check http://www.dcemu.co.uk for a full tutorial ) . If the sound is coming from the dvd drive you can easily test by swapping out discs , running a disc drive cleaning device / kit , disconnecting the dvd drive & booting your system without it or with a compatible replacement .
One last thing , take note of any blinking lights ( RROD , E74 , Etc.. ) as this could be causing your noise issue or just a symptom .

Cpu fan noisy/chip fan fail error messages


pils,

Yes. This sounds like a fan issue. The noise often comes from bearings failing within the fan. Also, a failing bearing can make things harder on the motor as it brings the fan up to speed. This is likely the reason that you see increased warnings during the fan speed check while booting because it comes to speed more slowly as bearing wear increases.

I give this a 90% chance that your CPU fan is causing the issue. Since a decent CPU fan will cost you ~$20 online, it's not much out of your pocket if you happen to uncover another culprit.

I'll keep an eye on this post. Let me know how things go.
