900D fully liquid cooled project

Hey guys.

As some may have seen in the LC-Topic, I intend on building myself a new little fully liquid cooled system. The last project of this magnitude was my "me-monstro"-build which two and a half years ago was pretty much the most ideal system. I still regret a bit getting rid of this beauty and I want to see if I can top this.

Definitely I wish to avoid the problems I had with this rig though, that's why I will take a lot more time this time around in building the new build.

Key elements of the new build I already know of:

Case: Corsair Obsidian 900D
Radiators: 2x 480 monsta (80mm thick) radiators with Corsair SP120 quiet edition fans on push.
Pump: Dual D5 pump in a single loop
Fittings: Bitspower Black sparkle
Coolant color scheme: blue (again)

As the things arrive I will make pictures and slowly but surely this project will commence. I have NOT decided on any hardware parts yet. And this thing is meant to be a project build. The more time it takes me to get it perfect the better. :) I will spend loads of time on cable management and I will also probably go with Bitspower Crystal link for every bit of the computer which can be thou the window.

I don't indent on modding the case (at least not yet).

Also the progress of this build might be slowed down as I still haven't sold my folding farm. It has to go for me to really make this build look the way I want to.

I am too enthusiastic about it so I started by ordering the first parts of it today. These were some basic fittings, reservoir (Bitspower 250), pumps and pump top (EK), a filter and some tubing. I will start by cleaning everything and making a couple of leak tests with the system. I also hope the filter will work well and get all the crap out of the radiators.

As soon as the 900D is available I'll get that and some SP120 fans. I kinda set my mind on the fans because I think I can make it look best.
 
Ok. The first bits and pieces arrived.

I'm still waiting for the fittings though. Then I can make the leak test and start to filter the loop from the manufacturing process...

 
When they make the radiators, they don't flush them. So there is quite a bit of dirt in them. Once a loop is set up, the dust or little pieces flow through the loop. At some point they can cause damage to the pump(s) or the settle someplace. Usually on the small fins of the water block as they replace the filter. This can cause the water cooling performance to go down.

If you have a water cooling, you should check out the radiator guide. It usually says that it's highly recommended to flush it before installing it.

Since I have enough time, I'll be flushing and filtering everything for a day or so. I couldn't find the Corsair 900D on stock yet here in Austria (or Germany)...

Its common practice to flush the rads before building your rig. No gay filter needed. Just put a hose in one side of the rad and flush with tap water. let the rad dry out before using it with the rest of your rig. SIMPLES>

stop braking my balls, would ya? :lol:

So I chose the filter, big deal. I think it's nice, and I might end up installing it into the case anyhow. Looks kinda cool IMO.

But you'd be surprised how many people forget (or don't know that they have) to flush and are surprised when their pump dies within a few months.
 
When I first started watercooling I never flushed the rads, and was never told to or even knew I was supposed to as I didn't look for advise (oops).

Now when ever I do a rebuild or a fresh build everything gets flushed including blocks, barbs, rads and tubing. Everything is then left to dry and then the system is built.

Anyway looking forward to seeing this build, as I cannot wait to see a proper build done in a 900D.
 
I always, without fail, new or rebuild, always flush my loop.

And I always without fail, new or rebuild re-clean and flush my radiators seperately.

Never, in 8 years+ of watercooling have I ever needed a filter... (or have I had anything growing in my loops)...

From a neat and tidy point of view, I'd send the filter back. It won't do anything but slow down your flow and potentially if it DID catch a bunch of muck and dirt, it could clog up and stop flow altogether... worse-case-scenario

I've also had a loop that didn't need ANY maintenance for 3 of those years and never had a single issue with it. :)
 
Ok. Now finally all necessary parts arrived for me to do some leak-testing and cleaning out the radiators.



Gonna do 1h with tap-water and then another hour with destilled water, and then I'm letting everything dry before the next phase. Which should be the case at this point







Hopefully the 900D will be avialable not in the too distant future
 
Okay.. to me... Flush means, water in one end, and emptied out the other, not in a loop. Otherwise it just re-circulates dude?

Big bucket-o-h2o at one end, bucket-o-air the other, use pump and couple-o-tubes to transfer water from A to B. Empty, rinse, repeat.

Also, you left the filter in! Thus rendering the flush even more pointless! lol
 
I flush with tab water both radiators. Then I set up the loop for leak testing as mentioned. If there are more parts in the loop which need to be flushed, the filter should take care of them. That's why I bought it.

Seems you missed the posts and discussions of the first page where we had that debate whether flushing or filtering is better. It's the first time for me to filter too.

Every radiator was flushed for a few minutes and now the filter should take care of the rest. 1 hour tab and one hour distilled water. In a few minutes I'll take the loop apart and let everything dry out properly... I haven't decided yet whether I'll put the filter in the 900D...
 
Gonna be watching of course, looks interesting.

Aside from that, wouldn't it be interesting to have a really effective, high quality filter for a (for arguments sake) 10 litre flush of various new rads from different manufacturers. You can't say you're not curious to see which of the makers are better or worse for bits of crap left inside after manufacturing ;)
 
I did flush both radiators first for a couple of minutes. After that I started filtering the tab-water loop for an hour and then I changed filter and water and there were more bits and pieces after the second hour.

So I suppose filter might become a part of the finished product too. It seems that no matter what you do, you can't possibly flush out the rads perfectly. Probably I will always end up finding waste in the loop...

No mate, I was actually quite involved in that.. perhaps you missed it?
 
This looks to be a great build :) Just a quick question about that pump top, do you block off one inlet and one outlet and the pumps work in parallel, or do they work independently?
 
the pump-top is made for a single loop and for two D5 pumps...

This is the one I use: http://www.ekwb.com/shop/pumps-and-...ies/ek-d5-dual-top-g1-4-csq-black-acetal.html

Alternatively if you wanted to gave a dual loop you'd need this one: http://www.ekwb.com/shop/pumps-and-...ries/ek-d5-dual-top-2-loops-black-acetal.html


The pump top I use has two inlet and two outlet. I have a hard time thinking of how to use all 4. But there is definitely the option. In the picture of my leak testing you may see that I use 3 of the 4. Two for the loop and one being a draining system....
