Case Mod - In Progress Project Dianoga Redux

Project Dianoga





The idea.

I am forty two years old and have never water cooled a rig of my own. I built one for a friend back in 2003 but that was the closest I ever came. However, recently a guy on another forum built an entire water cooling loop for 30 euro and it gave me an idea.

What exactly would happen if you went onto Ebay and changed it to "Buy it now" and then set it "Price low to high" and bought the absolute cheapest water cooling components you could buy? well, we are all about to find out.

I almost called this project the forty year old virgin but I figured being 42 it would not be as punchy as Elvis, plus the song "In the ghetto" was simply too funny to pass on.

The components. I will list them here and what they cost. I will indicate what is ordered and what is not.

The res.

XSPC single bay brand new in the box. I got this free.



Barbs, £1 each.



CPU block £9.50 (ordered)



If I am correct and the four holes are for AMD then the rest will be coming off.

GPU block £16 (not ordered yet)



As it says on the tin. I have measured the holes and they are 61mm, however I need to break the card down and make sure it won't hit anything before ordering.

Radiators. Two 120mm with barbs £9 each (not ordered yet)



Pumps £2.90 each ordered.



Crushable hose clamps of various sizes, 10 for £2. I have not ordered these yet as I will need to use my vernier to measure the exact sizes needed once the loop has been built.



Flow meter with temp gauge and barbs £7.50 not ordered yet



Fans £3.79. I will use four



Hose - £3.50 for 5m 8m ID 11mm OD



I have decided that all of the pre existing mods will be changed and redone to suit a green colour scheme. This means I can convert the existing cables over to green to make it more of a challenge.

I will also highly likely be using a Phobya triple radiator stand but will mod it heavily to hold the first rad (will explain why later).

Please note (for certain forums) that the case has already been heavily modded but of course I will be modding it even more heavily to take this WC gear.

The first thing I will be doing is rebuilding the rig on air cooling and then installing an OS before running the air tests. I will then use these at the end to compare to the water tests.

I've obviously done a lot of research on the pumps and blocks etc and they perform very well. If you have any questions please ask

The initial plan is res - pump - rad - GPU - pump - rad - CPU - return but I will likely test it in all sorts of configurations.

Other specs.

AMD Phenom 2 X6 1055T
8gb DDR2 800
GTX 950
Asus M3A32 MVP Wifi
Cougar Commander 620w
Alienware Predator 2.1 chassis (modded)
2x500gb laptop drives in Raid 0
SSD (need to replace)

 

OK so some inventory. If you look back at the pic of the Alienware you can see where the front intake is. It's under the cages right at the front. I intend to leave that Cougar fan where it is (140mm) and then build a stand so that the front rad is at the edge of the 5.25 cages, bringing it more in line with where a standard front intake fan would sit. So the 140mm will blow air into the rads... One issue, how do I stand up the rad and hold it there? Well I had a dig through my cupboards and found a 360 rad stand which I am going to mod so that it takes a single 120mm rad.



There's also a 360mm bricky grill there I will cut for use on the intake rad. Mostly so I don't stick my fingers into any fans. I also found these.



So far I have seen two Samsung modules on the back of the card, so there may be two more on the other side? I won't know until I strip the 950 and take a look. Talking of which, here he is



I also remembered that the SATA cables that came with the PSU were not long enough so I will remove the orange Bitfenix ones I ordered and instead cut them and solder this on.



All of the cables will come out and be braided in camo fluorescent green. I used red stuff for the stereo project and really liked it The silver Dinoc will also go for something a bit more up to date and tasteful.

 

Sounds like a fun project. I wouldn't touch the GPU block with a stick. But overal I find it funny to see what will come of this gathering of Chinese components

Just make sure the barbs on all components are the same and that you are not buying an aluminium raditator since your block(s) is/are copper.

 

Sadly the barbs are not the same. They vary from 8.6mm (pump) to 10mm (blocks etc). The rads are aluminium but seeing as I will be using only distilled water (and possibly some colour drops) then I can't see why that would cause a problem. The guy who did the 30 euro loop was using the same rad (only 240mm) with the same CPU block and pump. He never had any major issues, apart from a leak from the pump before he put cable ties on.

The trick apparently is to use 8mm ID hose (ordered) and then put the ends in boiling water. Given they are PVC they then become softer and you can get them on and when they cool they form a nice tight bead The hose clamps I am using are industrial and are usually used on washing machines and dishwashers ETC so they should hold the hoses nice and tight

The guy who built the 30 euro rig saw a difference of nearly 40c from the stock cooler to his ghetto loop using a 240 rad.

 

So thanks to Photoshop working in MM I can design the internal layout.



This is where I am at so far, after measuring what I have and getting the other sizes from tech docs



I had the foresight to make everything as separate layers so I can jiggle it around without too much hassle

Neither would I, that is the whole point.

Try and remember back to the days where water cooling a PC meant going ghetto because there was no other option. A copper block that makes contact with the GPU and has water flowing through it will work. All of this anal nonsense we see now (and sky high prices) are down to the fact that capitalism has come into play. I mean seriously, £70+ for a GPU block? they're nice and all but they all serve the same function. Some may be better than others but it's only a GTX 950 with a tiny die and hardly anything else on the card.

This would be a proof of concept if it were not for the fact that some one has already proven it.



There it is alive and well running distilled water and food colouring lol. I won't be using a ghetto res though thanks to BLC

That setup there shaved 40c off of a stock cooler. About what you would expect of a 240mm AIO by Corsair etc. I've already researched the pumps too (as well as seeing them taken apart, they're crushingly simple).

Vid of pump.

I will be using two.

 

It doesn't matter what you put in there I think. It is a liquid that is a bridge between the copper and aluminium. In the short run you won't notice, but in the long run your copper block will have a very nasty colour.

 

I see. I'm not really worried about that. Will experiment with liquids and coolants when it arrives

On a cold and gray Chicago mornin'
A poor little baby child is born
In the ghetto (in the ghetto)

Set up ghetto, set up ghettoooooo



Argh, forgot it doesn't have an OS on ! when I robbed the Mars I also robbed the SSD



So I grabbed a ghetto laptop mechanical drive and started the install.



It's finished installing, I'm just installing the Nvidia drivers etc. Then I will get it into Steam and leave it benchmarking for about an hour then take all the temps

 

Morning update

After installing Windows 7 Pro yesterday afternoon I was having some serious issues. I could not run the benchmarks, because they were making the rig black screen and become unresponsive. I have heard about black screen issues with Nvidia cards but had never had the issue myself. Until now.

I tried pretty much everything (older drivers, DDU etc) but nothing helped. As soon as I launched a game or benchmark that used the GPU it would black screen and become unresponsive whilst the monitor remained on.

I then read about some laptops having this issue with new games and the solution was to run them windowed. I ran Valley windowed and yeah, worked perfectly. So I started doing some digging into the issue myself and eventually I realised the monitor was running at 59hz so I force changed it under the adapter settings and the PC black screened no game.

So now I knew I was onto something but still wasn't sure what to do about it. I upgraded to Windows 10 whilst I still could but the problem remained.

Then after a nice big cup of tea this morning I realised I could create a custom resolution under the Nvidia control panel. I created one for 1440p leaving everything alone except the refresh rate which I changed to 59hz.

Problem fixed.

So I will get on with the benching later

 

Just a quick update. Now that I have the rig functioning as it should I have decided to do some design work on it also. When I quickly restored it back in December of last year it was just that, a quick restoration to get it going and a few minor upgrades etc. However, I have decided I want it to look better inside. I am going to go for a silver/met green/black colour scheme. I only need to braid three cables (6 pin PCIE 24 pin and 8 pin EPS) so I have decided to order this.



It costs twice as much as regular cheap paracord and will probably be harder to use (as it's thicker and jams pins easier) but I have fallen for it. I am then going to make my cover panels out of silver acrylic.



And in a tribute to my first ever Alienware computer this.



Candy apple metallic vinyl.

 

OK so the air testing is complete. First thing I did was install CPUID, GPUZ and HWMON then open them all, using the latter to record temps.



I then set up Realbench to stress mode/8gb ram and set it for an hour. However, after thirty minutes it was obvious that things were not going to get any hotter. Any way, I also ran Unigene Valley (just left on not benching) and again after thirty minutes it too refused to get any hotter.



What surprised me was how responsive the system is now that I have fixed the issue it had. I was easily able to browse the web with the crap being thrashed out of it.

And the results. Lowest temp on the CPU was 17c. Highest temp was 39c. However, I expect these numbers to be false and highly suspect that the actual temp is TMPIN0 like it was on my 8320. This showed a minimum temp of 33c with a maximum of 49c.



Moving over to the GTX 950. Minimum temp shown was 29c and the absolute maximum was 65c.



As I said, pointless going on as it was just staying the same (or dropping a few C when the new scene loaded on the GPU, or when the test changed on the CPU).

 

You have made someone in HongKong very happy.

 

Haha not yet I haven't

All I have ordered is the CPU block and two pumps. I was going to order the rest next week. However there has been an interesting development and Elvis may be performing in a rhinestone suit

 

OK so here is where I was at at 2am lol.



There's only one thing worse than dirt. Tape adhesive.



And there is only one thing worse than tape adhesive and that's moar tape adhesive.



I'm not sure of much but I know this is going to SUCK.

 

Iso alcohol will bring that off , soak and rub with a cloth and it will be gone in no time

 

Yeah that's what I'm using I just hate it cause it goes all gummy and nasty.

 

Naptha. That and toilet paper removes tape residue completely.
Just don't smoke and do it outdoors.

 

Sorry for the lack of updates. It's not usually my thing to start a log and then go quiet but I have been in talks about this build and instead of having cheap laughs I may invest into it a little more. We shall see

Any way I got all of the gunk off.



The back side was actually easy as the alcohol cut straight through it. The other side though? nightmare. At some point in time I thought it was a good idea to stick the graphic from a XFX GTX 260 Black Edition over one of the case's holes. What I did not realise was that it was double laminated with cardboard and all sorts of other crap on it. It was literally like trying to remove that 1970's vinyl tile on a roll crap with a steamer. After about an hour and a half I finally got it off but I'm never sticking anything stupid anywhere again.



You will notice I have removed all of the cable management trims. There's a good reason for this

I managed to cobble up enough cash to buy the braid so that I have something to do over the coming days. I don't get paid until Friday and I'm already pretty bored lol.

 

Braiding done. Like a wally I did not look before I ordered the other stuff and had forgotten that I had neon green and gray left from a project I didn't bother with.



8 pin EPS



And all of the cables I needed for the rig. God bless simple GPUs

 

So I dug out a few old molex connectors and some wire, in order to make a few extensions and splitters etc so everything reaches.



Harvest a few pins.



New braid.



So the first extension is finished. Very difficult braid to use but looks lovely.



Then the doorbell went



And.



And a massive thanks go out to Lewis. Ain't gonna be no ghetto now

 

Oops forgot the revised plans



Noting the res will be facing you as you look in.
