This doesn't neccesarily indicate a problem. Just to be sure, Check your systems temperatures in your notebooks BIOS.

Press F10 when the HP Invent logo shows up when you boot it.

Do not forget that a notebook generates a lot of heat. Since all internal components are literally packed. A notebook is fully filled with parts.

At what point does the fan return to normal? And at what point does it speed up?

Greetings,

Tip

Computer or laptop turn off automatically after sometimes


this reason comes due to over heat of processor.
solution-
1. check the heat sink fan is running or not
2. chech is there paste between heatsink and processor.
after solving these problem if your problem exists.
then it may be due to slowly of the fan speed and the heat sink goes over heat.
so, open the stiker over fan then put 1 or 2 drops of oil in the hole. then run your fan by manually your hands if the fan goes ok then re install it.
now your problem is finished.

Hi.

Even if a defective CPU may decide to overheat by itself the case would be quite unusual.The problem is usually caused by a defective fan or by a fan incorrectly installed. Be sure that the fan is starting and replace the fan.

As a first step try once again reinstalling the fan. This time measure the temperature using a software like SpeedFan.
If there is no change in temperature reading, try replacing the fan. A fan with damaged bearing may provide insufficient cooling resulting in overheating.

PS: be sure that problem is temperature and not system crashing. The temperature monitoring software will tell you.

Regards.

My dell optiplex gx 620 system fan run so fast and produse a lot of noise when i play games or downloading data from net


Open up the computer and clean the dust out of the fan and processor heat sink. If it is a temperature-controlled variable speed fan, it will probably not have to work so hard to keep the processor cool.

If it is a fixed-speed fan, it may be getting loud because the bearings are wearing out. Gently try to rock the fan blade unit - it should not have any wobble or slop in the bearings, and it should rotate easily.

If necessary, clean as much dust as you can out of the power supply without taking it apart.

Do not use a regular vacuum cleaner to **** dust off the motherboard. The high-velocity airflow may generate electrostatic charges that can damage the board. It's probably OK to vacuum out the heat sink if you hold the fan still to keep the vacuum cleaner from over-speeding it.

I don't think you can install 8gb of ram into that desktop. If the processor fan is too loud check it for dust or any other obstructions. If there aren't any try replacing the fan - it could be a bearing in the fan.

My hp media center m7160n computer powers up, has a definite fan sound, normally the fan sound diminishes and the computer boots up. For the last several months, the high speed fan sound would not diminish...


How did you clean it?
The last one I worked on had the fins of the Heat sink totally blocked with dust. This will make the fan scream trying to push air thru the heat sink to cool the processor. If it isn't cooled it will shut down in short order.
You must BLOW it out. Use a pressurized air can. Better if you have a compressor with a nozzle.

The other issue may be the interface between the CPU and heat sink is defective. Heat sink moved or become loose.

Of course by this time the processor could be dead also.

CPU FAN SPEED IN HP Compaq d530 Small Form Factor Desktop PC


The fan/heat sink on these models get plugged with dust very easily, use an air compressor or can of air to blow the dust out of the heat sink and fan. In extreme cases the thermal paste gets dried out and needs to be re-applied to properly cool the processor.
