XPS Desktops

[svdgabriel]

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

Ok thanks Tarak. I will give that a try then. I’m mostly going to be using it for mining and general web browsing so it won’t be CPU intensive at all. Mainly want to get good airflow within the system. I will monitor the temps for my CPU and then make the decision if I should by a CPU cooler then.

Remove the 3.5 HDD upper caddy and you can mount a 92mm fan at the upper portion of the case.  It will suck air thru the front cover since it got holes cut in the middle.  Mounting will be tricky but can be done.  I got the XPS 8940, i7 10700 (non K) with the RTX 3060 ti.  First bench mark causes thermal throttle since it peak at 100 degree c.  I installed the NH-D9L with the suggested method on page 5, and upgraded the rear fan with the NF-B9 redux:1600 and added the same one at the upper front.  Now CPU stay 100% at turbo speed (4.5-4.6 Ghz) and temperature idle at 75 (80 max but just spike when programs kick in) under load. 

Hope this help.

Regards.

Thanks. I wish I got a one without the 3.5” HD. I will need to see where to keep that. I don’t do cpu intensive tasks and am mostly planning to use it to mine crypto. So I just want to get good overall airflow to maintain a cool system. I was thinking I could squeeze a A9-14 between the gpu and case but I’m realizing that’s definitely not possible. For anyone who’s reading this is what a i7-10700 with rtx 3070 looks like. I’m currently running it without a side cover because the gpu fan speed drops from about 47% to 30% while maintaining temps at 57C

Hi, Exactly the same fan / cooler upgrades I bought. The rear fan is in..... grabbing the silicone plugs was a tough!  I am going to do the cooler tomorrow.  Have the M3 x 16mm screws and M3 washers.  Just to confirm, you used one washer per screw. And did you use the black spacers? Thanks in advance.

Hi folks, I'm thinking of buying a 9840. Since I currently have a 9810, which gets quite loud at full load, I read this thread with interest. Can anyone here confirm that a 9840 with i9-10900K has a better cooler built in? Somebody said somewhere that the K processors didn't have such a small CPU cooler built in. Can you rely on it?

No...I ordered the Dell 8940 white special with i9-10900......it did not come with cpu cooler upgrade...

@Own8940 i9-10900 or i9-10900k? That would be too bad.
