Hi all,

I have a problem with the power ventilator of my computer and I couldnt find much info on the net about it.

So thats why I turn this forum, which I found while browsing

My computer is about 2 years old and has never given me any problems.

But lately, almost every morning when I switch my pc on, the power ventilator suddenly makes almost no sound anymore.

This is really strange as it used to make quite a bit of noise.
The noise was also very consistent.

But now every now and then the noise goes up a while and then goes down again. At that time my computer is really quited, which is nice ,but also quite suspicious as he never had this behaviour.

When I check the ventilator it is turning but somehow he makes only a half of the noise he used to make...... and then after a while the noise goes up again....

I still dont have any other problems with my computer and its functioning pretty good.

I hope you can give me some suggestions as to what I should do...

Please let me know

Some fans inside computers can adjust themselves according to the temperature - they slow down when everything is cool and they speed up when it is getting a bit too hot.

However, if your PC has never done this before, I wold strongly recommend getting a new power supply immediately (I assume that it is the power supply fan that you are talking about). It sounds as though the fan is not working properly and it only takes a small cooling problem for some parts to get slightly too hot and become permanently damaged. This often means that you could have to buy a new processor or motherboard or both if you do not make sure everything is cooled properly.

Thanks for your answer!

I guess I need a new power supply.
The only question is what kind of?

I mean what specs does the new power supply needs to be compatible with my computer?

If you open the system case, you'll see the big power supply unit (PSU) at the top. They are normally labelled with a power rating in watts, e.g. 250W. That's basically all you need to know. Make sure that the power rating on the new PSU is the same or higher than what's fitted now. Most people would take the opportunity to get an extra 100 watts to allow for future upgrades.

The only other thing is that, if the processor in your PC is a Pentium 4, you need to get a Pentium-4 compatible PSU - most new ones are.
