XPS 8940, Better 3rd party cooler

Hello there

I would greatly appreciate any help to find a new/better 3rd party cooler for my XPS 8940. It came with the thin and small stock cooler and is overheating the whole time. I got a i9-10900 processor with 128 GB of RAM and I need this computer to generate some GIS layers. These jobs take 2-4 hrs every time and I can see that the processor is throttling or C° 97+ all the time.

I tried the Noctua 15S but the problem is there is no space for the bracket under the motherboard. The stock fan screws directly into the chassis from above.

Thank you very much

I also saw this video on LTT (Can you cool a core i9 10900K for cheap?)

seems like the Cooler Master hyper 212 might be able to mount on to the computer directly without the need of cutting anything. My solution was a bit desperate, I needed it running ASAP and is working great right now.

Great Job! Good to hear your temps are improved.


Did you order your XPS 8940 with the 500 watts power supply?

I order a XPS 8940 and one of the component I'm interested since I place the order was the processor fan and heat-sink assembly that is shown in all advertisement Videos and photos from Dell and service manual page 12 for this XPS 8940 in this link:

I'm concern because I seen few photos and videos of people that recent purchased this XPS 8940 and shows a different processor fan and heat-sink assembly like the one you mention "like a pancake with a small fan on the top"

I called my sales rep and ask him about this, he asked his manager and the response was that the units with 500 watts power supply comes with the processor fan and heat-sink assembly that is shown in the service manual and advertisements.

I hope this is correct.

@VeloDell    . . . he asked his manager and the response was that the units with 500 watts power supply comes with the processor fan and heat-sink assembly that is shown in the service manual and advertisements.

I'm not sure what the PSU wattage would have to do with CPU cooling  

From my experience with the XPS 8930 . . . if you order a processor the ends with "K" you will get the upgraded cooling system.  For the XPS 8940, non-"K" processors are 65 watts, while the "K" processors are 125 watts . . . which would require the additional cooling capacity.

Perhaps some XPS 8940 owners can confirm one way or another ???


I have the 8940 non-K i7 and it came with the cheaper fan cooler.   The Dell marketing literature and also the service manual are very misleading as there are no pictures or diagrams showing the cheaper cooler.


FYI - The part number for the larger cooler shown in the service manual is VWD01.


Anybody installed the Intel Dynamic Tuning Driver which Dell just posted? 

It's "...a power and thermal management solution that is used to resolve fan noise, overheating, and performance-related issues ...".

Does it make any difference..?
