Cooling fan noise in my XPS 13 7390 2-in-1

I had a similar situation with a loud fan noise followed by an error message at boot time.  I'm also out of warranty, so I opened up the case and blew out the fans which fixed the problem.  I thought I was done with this, but maybe the fan will fail again in a few months like yours did.  I found a replacement dual fan and heatsink unit on eBay (the part number is 0VMDK), but the service manual for the laptop doesn't say how to remove the old one.  I asked the seller if they could tell me how to get the old one off, but I haven't heard back from them yet.

There are detailed instructions for removing the heatsink assembly (note -- separate from removing just the heatsink itself) in the service manual.

@ejn63 Incorrect. You are referring to the 7390 clamshell model. The post is about the 7390 2-in-1. There are not instructions in the service manual for how to remove any combination of the fans or heatsink. Here is the proper link to the service documents library:

I had the same problem. Opened and dusted fans with compressed air and fan continues to work nonstop regardless of level of computing activity. Am trying this next: https://youtu.be/nA1qFjOJ9Y4

(reinstall older bio version, reset power settings) 

Fingers crossed. 

Similar issue. Noise would come and go. Only recently I started seeing actual fan failure errors. Opened 'er up, carefully cleaned the gunk off the two fan blades, and (for now) I'm good. Unfortunately, when we're not really filtering incoming air, this will keep happening. 

Yep, it's back. It's clear from all the posts related to this topic that these fans were lemons. Normally, I'd chalk this up to the physical wear and tear a laptop takes, but with the pandemic and working from home, this thing's been sitting on a clean desk for 95% of its life. I'm out of warranty at this point, and I don't think Dell will do the right thing here -- guess I'm off to eBay or the like to find a replacement part and hope it's any better than the original...

Yep here's another one after ~3 years. Granted, I load this thing heavy. Gonna look for spare parts then.

Looks like there's a couple of versions of 0VMDK, possibly shared with 9310. AFAICT specific to our machine is AT2C9001DT0.

And from 0VDFK8, I think Sunon EG50030S1-C170 and C180 could be a drop-in replacement. At least I can't tell any difference:Delta ND55C43Sunon EG50030S1

Further detective work seems to reveal that 0VDFK8 AT2WX002SCL might be compatible.

But even if not (for the whole unit), fans can be found separately: Delta ND55C43-18M14 and ND55C44-18M15

(Confirmed by a shot from https://youtu.be/86TCA26YwMc?t=2311 disassembly)

Left: Sunon - Right: Delta (original)

Today was the swap day

I see the difference now why they replaced original Delta ND55 fan with a "secured blades" Sunon. If you're swapping, I'd recommend the reinforced Sunon.

With no accidents, it's a fairly comfortable ~1h job. Just follow the Service Manual PDF for how to remove the System Board, because you need to access fan body attachment screws from both sides of the board. Not complicated - you don't have to disassemble WiFi, nor heatsink.

@lkraav​ Which part no. it is and where did you buy it from, i have several latitude 7390 2 in 1 having the weird squeaky sounds.

Please can I order for a single unit?
