XPS 8950, PSU rattle cause

Yup my XPS8950 PSU fan started rattling about 1 week ago.  I still have PROSupport.  They are trying to locate a 1000 watt PSU to bring for onsite repair.  Wondering, my XPS8950 has been running poorly for the last week, about the time I started to hear the fan rattle.  Any possibility that the fan rattle does anything to the PSU, to cause lots of issues within Windows 11?   Slow everything???   Thought maybe I picked up a virus or Malware.  Still testing for it...

@DD660​ unlikely.

Unless there is another component that goes bad in 1000 watt psu,

Mine is 750. 

PSU disassembly is not recommended by Dell because it houses capacitors that can store a lethal amount of electricity, even when the unit is unplugged. This is why our Service Manuals do NOT show how to disassemble a PSU. It only shows how to remove and replace the entire PSU.

Becasuse of the above, Dell has never offered PSU internal parts such as the fan assembly.

Thats why i specified to offer only to people who ask. Who are capable of replacing it themselves. you let it sit or drain power before you take it apart. There is no need to touch anything else besides fan plugs and fan assembly.

Im showing the solution because dell is not gonna fix it obviously

If your fan is seized already then psu will overheat and customer has to spend more money on a new one. But it will cost dell zero dollars and a lost customer

on a more positive note.

I like the design of the case and internal components.

No useless rgb fans or leds

another psu that i ordered 1000 watt just came in with same problem on the right side fan

i see the problem is cheap chinese grease that dries and damages the bearing assembly.

Not a fsult of dell but should know better to use those parts.

Chris-m can you recommend a replacement fan that will fit there and not have that problem?(better quality replacement fan) maybe one from different manufacturer psu that didnt have this issue?

Obviously for those of us who are capable of replacing it.

And for others who can take the psu unit out and have a professional replace the fans locally?

At least offer some kind of solution instead of doing nothing at all

update.
i cleaned the dirt and rust and used air tool oil
at first it was a bit squeaky but after about 3-4 months the noise finally went away and now its working good.

DELL if you fail to fix the defect in your product you have no right to tell people not to fix it themselves.

consider how many customers you have lost over this. and if it was cheaper to just replace the PSU for everyone who had this issue.

i had dell PCs and laptops for about 15 years now. and this would be my last one. because every single pc i owned had some kind of problem that should have been covered by warranty or recall but ended up costing me

@DD660​ Absolutely! As soon as mine started rattling the performance went from 100 to 5. It took about 30 minutes to close everything out and shut it down. Normally everything is closed out and shut down in about a minute. I blew out the power supply and used the compressed air to bring the fans to very high speed hoping to at least spread some lube around. On reboot, it was a speed demon for part of the day then the rattle and it dropped to the speed of an old 286. I replace the two 60mm wonky garbage 12v fans with 2 Noctua NF-A6x252 FLX 12v fans and the rest, as they say, is history. As soon as I hit the power it was a speed demon again and has performed flawlessly ever since. That was last spring and this thing runs 18 hours a day, every day.

Mine just developed this problem over the last few weeks — I assumed it was a hard drive failing until I did the stepwise diagnosis of disconnecting each internal drive and it still was happening.   Is there any official Dell response to fixing this or is the answer @DamonBob33 ‘s strategy of aftermarket fans? 

@DamonBob33​ Is the replacement fan the four pin or three pin connecter version?  Thanks

@Bjackson999​ I've seen posts and a neighbor that were under warranty and Dell acted like it was news to them. They sent out a repair guy who was not new at this issue. He brought a "refurbished" power supply, did some quick testing, and just installed the new power supply. I'm guessing repair folks and us know all about it but Dell just wants to play dumb. A replacement power supply can be found at https://www.dell.com/en-us/shop/dell-1000w-power-supply/apd/cpx-rd0g0/computer-chassis-components but note that it says "These parts may be new, overstocked, unopened, returned, or refurbished" so who knows if you're just getting the same problem again. My friend bought one and all is well so far (3 months and counting).

@Bjackson999​ 3-pin. I used the Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown) from Amazon: https://www.amazon.com/dp/B009NQMESS?ref=ppx_yo2ov_dt_b_fed_asin_title which is actually quieter as well. It's been 8 months of solid use with no issues.

@DamonBob33​  Thanks — I just ordered a set of them.  I appreciate the information. 

@DamonBob33​ Did you have to so anything to sort out which wire was which?  The colors matched on my Noctuas I got fast delivered so I just matched them to the colors from the Dell plug and soldered… but when I tested the system the performance is awful, so I am assuming it doesn’t think there are functional fans installed…
