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

I don't think so since it has a 5 pin connector instead of 4 pin.  If you are going to spend that much, may as well get the NH-D9L.  Pretty sure is the same if not cheaper price.

What is the total amperage that you have going into the fan header? I am worried to add an additional fan to the same header in fear of frying the motherboard. Can the header handle up to 1 amp or higher? There is little to no information on this motherboard so i am trying to be cautious. I was able to add a new exhaust fan. I also want to replace the cooler but do not want to remove the mobo. I'm looking for something with the same mount so i can just screw it in to the existing pre drilled holes.

The NH-C14S is just a 4 pin PWM fan isn't it?

I'm already rocking the D9L - works great on CPU but cool air doesn't make it's way down to the GPU area very well hence why I'm thinking a really large down draft cooler might be interesting.

did you remove the motherboard to install the bracket or just screw into the existing holes

I also got the non-k i7 and it came with the basic, garbage "pancake" fan cooler and not the upgraded fan and heat-sink assembly shown in the XPS manuals.

Hey, 

I am new to this so still learning. I have been reading every post (in order from oldest to latest) and made it to this part. 

You said the Noctua NF-AF PWM fan (92mm) is a good exhaust fan. I just saw that it is 4 pin fan but others have recommended the Noctua NF-A8 FLX which is an 80mm fan and is 3 pin. 

How do I know which one I need or which one is better? I opened the XPS 8940 case up but didn't take anything out or modify anything yet as I am VERY NEW to all of this. I am literally only doing it for cooling/performance, no other reason than to make my brand new pc last as long as possible.

 

Many thanks.

You are awesome for this. Thank you. The pics do help explain the procedure better. 

 

I am very very new to PC's and want to get all possible information before even beginning to play around inside the PC as I dont want to run risk of damaging any little thing. 

 

How complicated would you say this is for someone who is beginner of beginners with modifying anything related to pc's?

 

Many thanks.

Thank you for the detailed pictures. It makes everything easier to understand for someone who is such a beginner, like me.

Tarak, thank you for this. 

 

You broke it down in the simplest manner and made it quite a bit easier to understand. Thanks for all of it!

 

I hope it is not too challenging, as I am a beginner. Hopefully will be easier with all the fans and stuff in front of me.
