You would need:
1. Make and Model of computer
2. Processor Name, Speed, and type

To replace the fan you would also have to get some thermal greese to apply to both processor and new fan. Depending on the fan, you might consider asking a local tech to install it for you.

I keep loosing conectivity on my computer. all lights shut off and can not type anything in


OverheatingWhen 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 small brush and can of compressed airto do this.

CPU fan failure causes system to aromatically shut down..


Without a proper working cpu fan the cpu will overheat and shut the computer down... if not fry the cpu. You will need to replace the cpu fan and hope the overheating didn't mess up the cpu or something on the motherboard.

I changed my cpu fan out, when i started it up it ran 30sec and shut down. So i replaced new mother board without fan., it still shuts down after a few sec. I disconected the 4 pin power source and it will...


From your problem description it sounds like the CPU was overheated (and failed) before you replaced the CPU fan - so the fan replacement was too late. Since the procesor already failed, installing a new motherboard without a fan did not accomplish anything.

The 4 pin power plug provides +12 volts DC to the processor. When you disconnected it, the processor essentially could not run at all and the system is no longer capable of detecting the CPU failure and shutting down the power supply.

You need to install a known good CPU which is the right type and speed for your computer. Unless you are experienced in replacing,CPU's, fans, heat-sinks and applying thermal grease I recommend that you have a PC technician perform these tasks.

If you believe that this information is of value to you please rate me on the FixYa website.

HP Desktop 792n Intell 4 CPU fan won't come on. Overheats, shuts down. Fan checks out OK. Replacement fan won't turn on either. All works fine with external house fan blowing on CPU


Check the pins on the motherboard where you connect the CPU fan. Could be just a broken solder joint. You can connect the CPU fan to another connector for an alternate fan as a temp fix, especially if you are not adept at soldering.

Blank screen slow coming on md6 model 7700 fan was excesively noisey before pc stopped coming on all together, almost 4years old any ideas please?


Hi,

It sounds like the CPU fan has failed and is causing the PC to overheat straight away.

To determine if the CPU fan has failed you will have to remove the side panel from the desktop and check the fan.

If the fan is caked in dust try cleaning the fan blades and the metal heat sink with a clean dry paintbrush, then try turning the PC on to see if it makes any difference.

If it still does not come on or it comes on but the fan isn't rotating then the CPU fan will need to be replaced.
If there is still no power to computer then chances are that the CPU itself or the motherboard has blown.

This will mean a new computer or replacement motherboard.



Regards.

Fan overheat


Hello there iainmurray_m.

You have a desktop PC with an internal fan that is overheating, correct?

If so, without delay replace the likely failing fan.

If the fan is atop your CPU heatsink assembly, SHUTDOWN PC RIGHT NOW AND REPLACE IT BEFORE YOU FRY YOUR CPU CHIP!

Good luck, and please do post back ...
  • to let me (and interested others) know how things worked out,
  • to provide clarification or feedback.
  • if you have any further questions,

I have IBM 300pl. And it has strange fan problem.


A fan that no longer works will cause a heat problem. While it may not cause a complete failure, it can cause some strange things to start happening. Your best best is to shut the PC down and remove the cover. Restart the PC an determine which fan(s) has stopped working.

At this point, you can either 1) contact IBM for a replacement fan or 2) remove the fan yourself and google the name and model number of the fan to find a direct replacement and either order online or 3) visit a local PC repair shop to buy a replacement fan that matches the defective one.

Buying direct from IBM will probably cost the most, but will be the exact type needed for your PC. Buying locally will probably be cheaper and faster, but may not be an exact replacement unless it is the same model, etc.

When calling IBM you'll need the computer model, serial number and any other identifying numbers on it for them to help you out.

My computer is making a noise when i use it too much......i called bestbuy and they told me it might be the cpu and i want to know what to do and what is the cpu


Hi there!

It will be the CPU cooling fan.

You need to replace it soon as you can overheat and fry chips if it fails.

There is a lot of choice, but go for a middle range one if unsure.

Replacement is straightforward, but you MUST use correct earthing / antistatic procedures! - Buy an earthing wriststrap to replace the fan.

Hope this solves the problem for you.
