Hi all. a pc engineer came out yesterday cuz my pc was overheating. he changed the PSU, mobo and HDD. But now the pc is running flat out well i mean the fan. it never shuts up even if i turn the pc on and leave it for an hour it never idles. how do i make it shut up? if i open the case and slow it with my finger the silence is bliss.

please help me :)

thanks very much

What kind of "pc engineer" comes out to fix an overheating issue & ends up changing "the PSU, mobo and HDD"?

The P4 Prescott (I assume that's what you have) runs hot by design...58C-62C at idle is not uncommon. Plus the P4 has thermal protection circuitry built in to the can NOT overheat one to death, it's virtually impossible. If it get's too hot, it will "throttle back"...if it gets even hotter, it will shutdown completely to protect itself.

Fans make's a fact of life. If you feel it's a problem, call back the "pc engineer"

yea i know fans make noise, but they do go quiet in idle mode. and the pc engineer came out to change them parts because he was not sure wheter or not it was the fans or mobo which was causing the heat. he then changed the HDD cuz that was the warmest component. maybe he was an idiot lol. the thing is my pc has always been quiet. i mean dead silent, until i play a game or something obviously. now it is just running flat out. did ring them they said be out 15th tuesday to change the fan.

so jam the settings above are all ok though are they?

Also how do I tell what chip I have? And do you recommend i do anything to my PC to make it better/faster?

thank you for your reply!

Oh and when I had the overheating isuue it was running at 104C and kept running at this because i did not have a shutdown temp on or something. and to kind of explain how warm that was is that when i touched my tower it was like a radiator, just couldnt keep my hand on it. so i had to run it without the side on for a while.

but now if i take the side off it still runs hard. is there special fans out there which are made to be quiet? thing is cuz i have a warranty on this pc i dont really wanna spend yea im tight :) its never been noisy before.....

thanks once again.

Use this program to get the info about your CPU, board & RAM settings:

If your case felt like a radiator, it's an indication that you have inadequate ventilation. You should have at least one intake fan (usually in the lower front) & one exhaust fan in the rear. If your side panel has a fan, it should be installed as an intake (blowing in)

Yes there are fans that are quite. They run at about 2500 rpm have deeper fins with a bit more of an angle on them to push the same if not more air over the heat sink all while being very quite.

Why can't we put questions here?#

With only one fan extracting air and no fans pushing air in, it is little wonder you were over heating. The poor old CPU fan on the motherboard was working overtime just to keep the CPU temps down as it had very little cool air to work with.

I haven't seen a CPU yet over 1Ghz that didn't benefit from a rear case fan. Fans which don't come as standard.

I would install another fan at the rear just bellow the power supply fan blowing out and a fan at the front sucking air in. I think you will be surprised at the result. It will take some of the pressure of the CPU and allow it to slow down, that assuming that it is capable of being speed regulated which not all fans are.

I would avoid that "pc engineer" as well. To replace motherboard, CPU and HDD without first trying a couple a fans is a bit of overkill. But then he now has a perfectly good motherboard, CPU and HDD that you paid for.

installing fans is way above my intelligence of pc's....i dont know if your in america or something but i have never seen a PC in UK with a fan at the front EVER.what the hell is supposed to happen... cut a hole in the case?as for the back i only have one which is the power again i cut through the metal to install it?

is there a good place with instructions and GOOD fans?

thanks once again guys for all your replies.

Much appreciated

I don't know what kinda case you have, but a "normal" tower or mid-tower usually has provisions to mount cooling fans in the rear & the front...& some also install them in the side panel. You don't have to cut simply mount the fans using 4 screws & plug them in to either the motherboard or the PSU.

If you go to the following site & scroll down to figure #1 (System Airflow.....), you'll see what we're talking about:

Hey all, i know this is to do with the fan too fast, cause i'm rubbish at computers and it would take ages for me to look for the right stuff, but how can i make the fan go faster? My comp keeps overheating over nothing, im not stressing it out or anything, sometimes i just turn it on, get into windows and the whole computer shut's down and i need to take out the power supply out for a few seconds if it's to turn back on. Is it some program or something i need to get to change it. Please help, would be much appreciated. Cheers

Since it was quiet before and not now:

Since he changed the MOBO he had to remove the cpu. Did he remove the old thermal paste and apply new? If not that would account for it running hot and the fan going full bore trying to cool it.

hio guys. well he came today and changed the fan and also put thermal grease on it. he told me that because he changed my motherboard that i need to download a new bios for it as its a different model.

change the freaking motherboard anbd fan again. this time i will be in and not my partner, and he wont fu*king leave here until it works,

do have a question though, in the bios (i know nothingabout) is there any settings i should change or anything?

thanks agaian

Is everything working properly now?? If it is, don't worry about the bios.

If there is still a problem, the tech needs to return to fix it. Or ask for help here.

You obviously don't know that much about computers and so I don't think flashing the bios is something you should try. Do it wrong and you'll have a very expensive door stop.

no its still now working right, and he is coming back. look at my message above yours =\ to replace the same things again. i flashed the bios and i already had the latest bios. the tech guy is an a$$hole. i know nothing but he knows less lol.
