Help: Problem with Fan Noise / p7-1011de

Hi,

 

I bought a p7-1011de couple months ago and everything was fine until today. While opening this morning my desktop pc, the fan noise was really loud, extremely loud. This problem persists the whole day long, although I have not noticed anything different in the PC perfomance. Quick as always.

 

I opened the pc, cleaned the dust, tried to locate which fan was the problematic one (I am 99% sure it's the processor's) and the problem still persists. It's not a problem of temperature either, since it does not get any less noisy when I boot the computer without it's cover. From the moment I push the button, it makes a hell of a noise.

 

I checked also via HP Support Assistant and Hp Update, but it did not locate any problem or the need of an bios-hardware update.

 

I hope someone can give me a tip, because I am really clueless and I definetely want to fix this because my appartment is pretty small :mansad:

Re: Help: Problem with Fan Noise / p7-1011de

Pimpin2111,

Fan noise can be caused by several different problems.  I would suggest you d/l this, and report the rpms.

http://www.cpuid.com/downloads/hwmonitor/1.19-setup.exe

 

Causes:

1) dust build-up under the CPU fan, and in-between the heatsink fins.

2) Cracked fan mount

3) Loose fan screws, allowing fan to vibrant.

IT's time to call HP and get that unit replaced. Those temps and fan rpm are too extreme.

Re: Help: Problem with Fan Noise / p7-1011de

See http://h30434.www3.hp.com/t5/Other-Desktop-PC-Questions/fan-runs-full-speed-at-start-up/td-p/1525155... for more on this topic.

 

It appears HP service does not know what they are doing.  This defect seems common and is likely a defective LPCIO chip (this HP P7-1222 uses a Fintek F71858DG according to CPU-Z, and one of its temp sensors comes up at 99C on startup, intermitteently, causing the fans to race.

HP service is clueless despite my repeated contacts with them, and I am about to recommend to my university and to everyone I know to stop buying HP.


What more can I do when I cannot even get intelligent responses regarding a low-end model?

Re: Help: Problem with Fan Noise / p7-1011de

Problem is defective CPU. 

 

I had same intermittent fan problem and SIW showing TMPIN1 at 99C when this occurred (which is physically impossible).  Replacing the CPU, in my case an Intel Pentium G630, cured the problem.

 

TMPIN1 I believe is a sensor in the CPU's "northbridge"-function area for memory control, etc.

Correction.  Fan problem recurred - even after 2 motherboard swaps by HP, and a new CPU (intel boxed) put in by me.
