And im sorry if i post this in wrong section.

I need help This seriosly starts to piss me off.

Thanks

Please post your system specs so that we can give you some meaningful help.

System Info - See Your System Specs

Are you using your PC for gaming and if so, is it overclocked?

Have you opened things up to check for dust or loose hardware?

I'm loathe to make a snap diagnosis, but I'd be inclined to think your CPU heatsink is not so good and your CPU is overheating, meaning the loud noise could well be the cooling fan cutting in.

You need to be more explicit than your thread title for us to help you as there is more than one cooling fan and any number of reasons why the problem is occurring.

My Specs:
Ram: 6gb

the pc aint overclocked

I never changed any parts on this pc so all of these are default which i got from shop.
I was thinking that it was something with the cooling but decided to ask someones opinion too

hm, how could you describe it.
Think of an fan going so fast it makes an freaking loud noise.
its like some 'hmmmmmmhmm'

every now and then, now it started to do it all time but when cpu hits 80+ you can clearly hear an freaking noise. and its that loud my friends though it was an vacuum cleaner

I really do think that it is your heat sink that is causing the CPU to heat up, which means the cooling fan will cut in.

I'd be inclined to remove the fan and replace the thermal paste on your heat sink, and then refit the cooling fan.

If you don't feel competent enough to do this job or don't know someone who can do it for you take it back to the reseller as with it only being 8 months old it should still be under warranty.

so buy a new fan or?

and how much one could cost?

No, not yet. If the thermal paste is the problem, buying a new fan won't cure it.

The loud noise means the fan is working and doing its job.

You need to get the heat sink and thermal paste checked out first.
