Hello,

I am experiencing a problem with my 2010 Dell XPS-9000 (aka XPS-435T).  

The CPU (Intel 17 965 Extreme) is running very hot (up to 100° C at times).

As a result the fans are constantly running.  I'm not sure why there appears to be a change in it's behavior but I'm a pretty concerned.

I've taken a screenshot of the current operating environment.

In the last two weeks out of 10 times it booted it gave a BSOD 2 or 3 times near end of booting.

What suggestions or questions do you have to help me solve this issue?

TIA for your replies!

Phil

Sounds like you have an issue with either the heatsink, heatpipe or the thermal compound attaching the Heatsink to the CPU. or it could just be and obstruction like dust or cables.

Take off the side cover look to see that the airflow is unobstructed around the CPU and blow out the heatsink, if the issue is not dust, then you are going to have to replace the thermal compound / heatsink.

If you are not happy attempting this, I would suggest asking for recommendations from people in your area for IT/Computer companies who are able to help.

If the CPU is running hot, consider the following things:

1. Dust and air blockage - clean the computer.
2. Thermal compound dried out - remount the CPU and GPU.
3. Run Task Manager and look at CPU usage. CPU usage should run < 5% more than 95% of the time. What is chewing up CPU, if anything?

Hello
Check if the heatsink is fully attached in the cpu
If it's ok then apparently a problem exists in the heatsink and/or in the fan of the cpu, That's the reason of the BSODs


They need to be changed or repaired

Ok, sounds like I should consider doing a good cleaning.  I've never cleaned it myself and its been at least 2 years since it was last cleaned by a pro. Is there a good FAQs that goes into the best way to clean it?

I do the following:  Open the case, use a vacuum cleaner MOST gently, brush (paint brush) dust AWAY from fans, parts and so on into the waiting vacuum hose. It is kind of obvious and takes more time to explain that just do. Do not put the vacuum brush directly on any parts. Keep it up and brush dust into it.

Compressed air is usually not a good thing.

Never use a vacuum cleaner / Paintbrush inside a computer case.
The server manufacturers warn against it and always recommend compressed air, so why use it on a desktop?

We always use compressed air, we have several hundred PCs, Servers et cetera on site and none have failed due to compressed air cleaning, and we clean them out once every 6 months.
One caveat though, but if you do use a compressor, ensure that it is limited to <3Litres per second and you have a condenser or dryer attached to the hose and ensure that you wear a mask.

Also, always ensure that you are properly earthed before attempting any cleaning, withy brush / vacuum cleaner or other.

Cheers

Got it. Since I don't have an air compressor I will have to rely on the compressed air that comes in a can. Will that be alright?

Think about air movement. Compressed air forces dust into crevices. Sounds good, but generally does not work well. If you try it, go gently. I never use compressed air to clean electronics (computers, power supplies, generators. you name it).

Most of the canned air products are HydroFluoroCarbon based and are not the best, go with John's solution.
Just be careful, go slow and make sure you are grounded, and if the wand of the vacuum is metal, ensure it is grounded to you. the vortex forces within the vacuum usually build up a static charge.

Ok, I will get going on the vacuum solution.  Will get to this over the weekend and repost with results.

i use always an air compressor - but several metres away from the pc to clean, and of course powered off.
that way nothing can happen
the fact that the cpu is hot can point to a bad cpu, or bad cpu voltage also
i would check the power supply outputs also - here a pinout :

Thanks to all who posted. Ended up just spraying with compressed air in a can. Took 3 cans to complete the job. CPU temp is now averaging between 40-60 deg. C.
