XPS 8930, upgrading fan, which thermal paste to use?

I am experiencing the same high heat issues others are/have seen with the 8930 and based on excellent threads on this forum like Dell630i's post on exhust fan upgrade , I am upgrading the exhaust fan and adding a lower intake fan using the Noctua NF-S12As.

My 8930 has the same upgraded CPU cooler/fan that @Dell630i shows in his post and I need to order some thermal paste but I see that some pastes are not compatible with certain heat sink materials like aluminum or copper.

I can find tons of recommendations on thermal paste but nothing specific to the 8930 with the i9 and the upgraded heat sink (whatever it's made of).

Can someone point me in the right direction on which paste to order?

Thanks in advance!

Re: XPS 8930, upgrading fan, which thermal paste to use?

For reference, here is a pic of HWMonitor after running a load test to keep the CPU maxed at 100% and the SSD throttled due to high temperature.

If this looks normal or high, please let me know but the SSD is running very hot so I also ordered a heat sink for it.  Hopefully a heat sink with a fan blowing over it will reduce the throttling.

XPS 8930 SE

- i9 9900K

It's crazy they are installing these ... as this machine can not be factory-configured with a Liquid-Cooler.

- 64GB Crucial RAM

That much ram is going to run very hot. Would likely need heat-sinks or aux fan.

- 2TB Evo Plus NVMe SSD

A NVMe-SSD of this extreme capacity/density is going to run hot. Some kind of cooling or pad is usually required.

- 2, 16TB Seagate Exos Drives using Windows RAID 1 config

Not sure where these are, but hopefully, there are outside the machine. IMO, they belong is a Synology NAS (or equivalent).

And repeat after me ... "RAID-1 is not a backup".

I am not a TIM expert, but this is what I used, @ an advertised thermal conductivity of 16W/mK

Phobya NanoGrease Extreme 

You should see a big improvement with the 120mm top exhaust fan. I moved my M.2 SSD to a PCIe slot inside a big heatsink . . . but any kind of heatsink and sitting in front of the lower front intake fan should be a big help with your SSD thermal problem.

Re: XPS 8930, upgrading fan, which thermal paste to use?

@Tesla1856, I have a heatsink coming for the SSD so that should help.  Never had to use a heat sink on a memory module before before but it looks like they are available.  I'll try the two new fans and SSD heat sink and take it from there. 

Also, RAID 1 is for fault tolerance and not backup.  I backup to offline disks and rotate them.

Appreciate the feedback.

@Dell630i, appreciate the recommendation on the grease.  I'm curious, did your CPU heatsink have a thermal pad, grease or both when you took it off?

I really appreciate all of the pics and details you provided.  Plus this summary post really helped with the myriad of choices so thanks @HanoverB!

Just grease. I used the cleaner kit linked below for cleaning and prep. I don't know that it is necessary, but since I had no clue what I was doing, I wanted to take every precaution.

I've never heard of using both on the same chip. It is usually one or the other. For main-processors, I've always used thermal paste.

If you are sure you want to do this for the first time on your nice machine, I suggest you watch some YouTube videos and read some articles.

I just see a triangle.  Maybe the mods have to approve the pic you uploaded?
