XPS 8930, is noisy under load, #2

Do you know which fan(s) is noisy, CPU, GPU, case...?

Do you have all the latest drivers, especially the video driver, installed? Have you installed the Intel Processor Power Management Utility for this PC model?

"The Intel Processor Power Management Utility helps lower the system temperature and fan activity through reduced CPU power consumption by low Quality of Service (QoS) threads."

Is it possible the thermal paste between top of CPU and heat sink has dried out and needs to be replaced? Lots of youtube vids about cleaning off the old paste and applying a thin, fresh coat of new paste.

Check the Service Manual for instructions to remove/install the CPU fan and heat sink.

Desktop was having issues with overheating and fan making noise. Dell provided in-home service after remote diagnosis 2 years back.

Desktop worked fine after that without any further issues. But since last 3 months, facing these issues:

1. Overheating, CPU and GPU temperature very high even when it’s not summer.
2. Fan noise – unbearable fan noise.
3. Even when computer resources are not being used for 25% - there is a huge CPU, GPU and power consumption.

As I am Computer Science major so I can figure out these issues are due to insufficient air flow, some components either not working or working poorly.

Visual inspection inside the CPU case, verified that side fan is died. Not loose connection but it died.

Computer case is not holding well from one side which is letting the dust to enter the case.

Also, could be issue with power supply.

Lack of airflow which is slowly deteriorating the computer.

Temperature inside is too high.

Even when the processor is being utilized for just 23% - CPU temperature is too high.

@ashutoshsharma  Have you replaced the failed fan now?  Also, have you considered reapplying thermal paste to your CPU cooler? 

I got the diagnosis done by one of the vendors. His suggestions/recommendations:

1. Computer case is very tight and having bad airflow. Suggested replacing the computer case with good airflow-based case.
2. Also, they suggested installing more fans on the body of computer case for better air flow.
3. Also suggested putting CPU cooler with thermal heat paste.
4. As the fans are dying and the Power supply unit(PSU) is not working efficiently asked me to buy a better Power supply unit that can support extra fans. Recommend modular power supply with Gold rating and slightly higher wattage.

Do you think, this will fix the issues?

@ashutoshsharma  As long as nothing vital to a transplant has been damaged, then I'd say it should provide a much better cooling solution.  Check out this thread to see what a few others have done.  You probably don't need to go as far to get reasonable temperatures.  Note the comments regarding the front IO panel.

Thanks.

I have ordered these parts:

plus some more fans and cables for the entire fix.

@ashutoshsharma  Are you going to be able to connect the motherboard in that new case? Dell uses customized connections between motherboards and front panels. So unless somebody has already done it, you'll have to map those connections in order to connect the motherboard to the front panel in the new case.

I have an i7-9700 CPU in my XPS 8930 and it rarely gets above ~40ºC, but I don't game or do intensive video processing, etc.  It sounds like your problem was a failed case fan, so wouldn't a new case fan have been a less drastic fix?

I replaced the fan on my own. Top fan was not working, fixed that. Power supply fan is also not working.

As this computer is really running at the very high temperature, it might have messed up a lot of components like fan etc...

Dell Support is of no help. They are asking me to buy their warranty even when I have warranty from Citi Visa credit card.

@ashutoshsharma  -  The power supply fan in the XPS 8930 only spins when it's needed. It does not run all the time like fans do in older PSUs. It's an energy efficiency thing.

Have you tried applying a thin, fresh coat of thermal paste between the CPU and heat sink?

already applied thermal paste also.

@ashutoshsharma  Have you looked at those CPU temps again, now that you replaced the case fan?

Yet to finish this work...was very busy with work and Dell's motherboard is not super friendly/documented. Moreover new case - I am planning to use more fans. unfortunately, only two fan headers are available on the motherboard....so finding the issue and then ordering the stuff....taking extended time.

As the main issue is too hot temperature, worst airflow, and power supply degradation, I tried using this

but Dell's motherboard has an almost soldered metallic part at the back, which cannot be taken out otherwise processor won't be held.

Dell's motherboard is definitely not easy to work with.

good day, 

I don't know if you have looked around at all the posting relating to the xps and this same issue of continuously running noisy fan and the computer running like a oven. 

here is the bad news, if you buy one of these xps its buying that problem and I say that because. firstly I used to work in IT.

I bought one of these xps 1320 back in 2007 I believe because the warranty ended in 2012 (I had it exteneded) during that warranty time they came out and replaced the heat sink twice I believe but the problem was always there.

I think originally I used it solely with external monitor (think it was a bit quieter then) but the problem was always there , noise and heat.

when I went to win 10 it became unusable  , speed or lack there of.

I still have the unit, it still looks pretty new.

its really unusable with win 10 and the heat and noise.

best thing is to avoid.

I am trying to put linux on it but that too is a challenge.
