Always wanted to do a computer build, and finally got the time to.

This is a build that has evolved over the past 2 years from a Z97 build with a G3258 to a 4790K, and finally to an X99 with 5820K. It has also evolved from an air-cooled system to fully water-cooled.

It has been quite a learning experience, the Ncase M1 is simply brilliant. Its very adaptable and the removable panels come in handy for all sorts of mods. I originally made some inlet and outlet ducting for the GPU to guide it out of some milled slots on the front of the case. Since going water-cooled, I've managed to fit all 3 EKWB Coolstream 240 radiators into this build: SE 240, XE 240 and PE 240 (as a Predator 240). Mostly it has been fun to tinker, and to mod. Next steps will be sorting out the cabling from the PSU.

Current setup is: Predator >>> CPU >>> SE240 >>> GPU >>> XE240 >>> Predator

The SE 240 sits on the bottom with some Slim Scythe 2000RPM fans. The Asrock board recognises non-PWM fans and so it can still profile them for reduced noise. I have also installed the Lian-Li SD-04B feet to give a bit more clearance for the air inflow. I doubt they actually do anything, especially given that the outflow is equally blocked by the GPU. I have previously shown that modifying the SE radiator fin spacing can yield a couple degrees of improvement, this would be a more significant change than the new feet. The fans are fed from the worst-placed mobo fan header on the planet. I had to mod a fan splitter to be able to access it under the PCIe clip. The Ncase frame also took a hit: one of the mini-DTX standoffs was removed to allow the SE240 to sit better with the GPU angled fittings

The XE 240 sits on the side bracket and is fed by an F4-120ER and an FF5-120. More than enough to overcome the resistance of this 60mm thick rad at higher RPM. At 85mm total thickness, the rad contacts the PSU, so the fan there acts to help pull air though which is then ducted up. The hose from CPU >>> SE240 fits under the PSU to allow easier installation of the radiator.

The Predator has been upgraded to push/pull and is on top of the case. It is mounted on rubber stand-offs to decouple vibration, prevent the fans from rubbing on the case and also help to ensure it gets some fresh air. The top panel has seen a lot of mods for the hoses and better routing of the power and PWM cables. These were CNC milled so that parts lined up properly.

The pass-though internal power cable has been modified to prevent interference with the rest of the hoses. This was inspired by: https://smallformfactor.net/forum/threads/black-copper-ncase-m1.1313/page-2#post-28171

This is still not finished. PSU cables need some shortening, and I will probably re-do the water-cooling hoses for better fitment, but I had to post something eventually. I will also post a few more images when its not looking like a gutted animal.

Edit 1 Anyone wondering why I didn't just get a bigger case: I didn't plan to do this originally. But given the option to start over again, I would make the same choice. Much more interesting to make something original/different than just install bits in a bigger case. You gots to have a bit of a challenge.

The titan Z is the finest demonstration of NVIDIA's math abilities. $1000 GPU + 1000 GPU = $3000 GPU.

Jokes aside, awesome build! Take a +1 :)

AndyAD submitter 1 Build 2 points 25 months ago

Thanks! I got the Z 2nd hand, would never have paid full price.

rhali8 2 Builds 2 points 25 months ago

That's great to hear :D

Again, awesome build! Enjoy it :)

Another rare TitanZ Build

Nice Titan Z, costs more than my car does!

The Titan Z on the Canadian PC Part Picker is 11 000$. It's always fun to do 2-way SLI with the Titan Z when making 100 000$ builds :P, when I clicked on this build it said it was 17 000+ XD.

AndyAD submitter 1 Build 1 point 24 months ago

It was never worth that much really. Hah- SLI, you crazy!

Tobi_Kenobi 1 Build 1 point 24 months ago

Holy rads, Batman! It was hard enough cramming 2 in my NCase M1, haha. Well, done. Temps?

AndyAD submitter 1 Build 2 points 24 months ago

Cheers, I'm still tweaking so temps aren't great at the mo- trapped air somewhere most likely. Will update when its sorted...

Chapeau 1 Build 1 point 24 months ago

Good to see this build posted!!

  • How to you find the slim fans? I guess you have so much cooling capacity you're not taxing them... Hows the noise/performance?
AndyAD submitter 1 Build 1 point 24 months ago

The fans aren't too bad, have tailored the fab profiles so they don't spin up much below 40degrees. Will post some info soon when I properly stress the system... bleeding the air took a while. So far it idles ~8C above ambient.

Or Sodium Azide.

AndyAD submitter 1 Build 3 points 25 months ago

True, and Sodium Nitride is Na3N. I suspect NaN would be quite reactive so would probably form an intermediary part of a reaction.

I was originally playing off​ the computer science definition of Not a Number - NaN. Though I do like a bit of sodium chemistry.

If you like halides, have you come across ClF3 ? Looks like great fun.
