Should I ever have to do that in the future, thanks for the credit card tip!  I was not confident that I could put the correct drop size in the center of the CPU to get full/uniform/effective spread.  The more I see this done, the less scary it looks.  But Dell hooked me up with what I wanted so I'm good for a few years 🙂

rh310, I just want to verify:  you upgraded your chassis fan from 92mm to 120mm and it resulted in no change in termperatures, just noise?  I am getting high CPU temperatures doing moderately intensive things and it's really making me regret my decision.  I have the 8930 with the i7-8700(non-k).  I think what might really help is the CPU cooler that comes with the K processor models.  Dell is really cutting corners with these machines and making them hard to upgrade in terms of case volume/arrangement, I'll have to recommend no one else buy one.

Options I can think of: complain to Dell to get the better CPU heatsink and fan

Complain to Dell to get the 120mm chassis fan, improving noise but maybe not temperatures

Underclock my processor to 3900mHz as described here https://www.dell.com/community/Desktops-General-Read-Only/Dell-XPS-8930-is-noisy-under-load-How-to-i...

Apparently pre-emptive underclocking can prevent both throttling and temperature spikes.

 

I would really like to know if a bigger chassis fan improved temperatures at all for anyone!

The 120 mm top exhaust fan will improve temperatures somewhat by removing hot case air. The noise/temperature issues are related. However, with an air-starved case design, you should considering adding additional front case fans and/or liquid cooling options.

Everybody; just do like I did in my "added front fan" thread.....….it's not that hard to do, get all that air coming through the front where it's supposed to.

Search for;  added 120mm front fan (with pictures)

If you are still interested in the "K" model CPU heatsink/blower fan I have one that I am no longer using I can send you. You would need to obtain the heatsink mounting screws that screw into the mobo. Just let me know.
