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

Good info, thanks. I will monitor temps and see if I'm comfortable with the system 'as is'. It's clear if people are after max MHZ of the CPU, keeping it cool is a key. I'm not certain why others are making these cooling mods but I can see doing this if they have added more memory, a higher power GPU, more hard drives.

@Anonymous @redxps630 Thank you both for the very detailed info

So here is my result! Took me a little more than an hour to complete, most of that was because of the silicone hooks for the rear fan, I was afraid that if I pull them too hard they will break, but they are actually very strong!

Assembling of the CPU cooler went smoothly, I actually live in Germany so I ordered the M3 screws and M3 washers on ebay from schraubenkasten.de for 5€, for those who aren't sure where to get them.

Temps have gone down to about 65, those were 95 before so I‘m very satisfied!

Although it also means that the total cost I spent for the PC was more than expected, but for the long run I‘m sure it‘s worth it!

Hey guys. Very new to all this pc stuff so just want to make sure of things before I go ahead.. About to fit the nh-u9s to my 8940 with a 10700 non-k processor. I have got all the required hardware (m3x16mm screws, m3 washers and the included noctua brackets etc), but have seen some conflicting posts about what spacers (black or white) to use... Can anyone shed some light please? I have already done the nf-a9 exhaust fan upgrade   

TIA

As per Darren_F, you will need to use the white spacers.  Darren_F also stated that he used two washers on each screw, A M3 and an M4 washer.

@Tarak Abu Adam  Yes but also in this thread JamesonB stated that he used the black spacers and only 1 washer. So confused now lol

Indeed, you are correct.

I ordered all the parts (cooler, 2 X fans, and NA-FC1 kit) and waiting for them to arrive from Amazon.  I got my screws and washers (M3 and M4) locally.  I will try the white spacers and see if only one set of washers (M3) if enough.  If I end up having to use the black spacers instead or also adding the M4 washers as well I will post here and let everyone know.

Ok so I just installed nh-u9s into my machine. Even as an absolute amateur, it only took about 30 mins all up. Can 100% confirm that the black spacers in the intel kit are what you need to use, along with the m3x16mm screws and a single m3 washer on each. Has dropped my idle temps from 35c to 28c and my gaming temps (fortnite and warzone) from 88c to 62c. Absolutely worth it imo, very happy with results
Cheers guys.

Nice.

BTW, did you add a second fan to the cooler, and/or replace the original rear exhaust fan?  If so, did you use the NA-FC1 kit?

I haven't upgraded mine yet as I am still waiting for my parts to arrive.

Just running the cooler with the single fan at the moment, and upgraded exhaust fan to nf-a9 pwm. Plugged both straight into their respective headers on the mobo and all was good.
