Cosmos 2 extreme water cooling system

@skyripper, I think the Y splitters tactic is probably a common one.
OCuk doesn't have many decent angle joint available, at least when I ordered so made do with that.

As for everyone else, the second iteration is stable, I'm updating it slightly and replacing all PVC pipes with copper pipes.

Got a new S2, so pics inc soon & big update, just been hectic at work & hunting for a flat near the office.

Can't wait to see how this looks with copper pipes - that's been one of my projects to do for a good while now. Once I get my head back above water financially, that's a route I'll certainly be taking...


Good luck with the house/flat hunting...
 
Not much progress at the moment. Works getting complex & flat hunting is tedious.

Few fitting problems with the pipes going into the ram blocks, not an insolvable problem but just taking time, which I'm short of. :\

Oh and I've not started work on modding the case yet to make a supporting pillar to attach the pipes to. Got it planned out, but no more progress than that.

I'm using a ram block atm outside the pc to see if its all watertight. Problem just finding a fitting the copper pipes work with, which only has 3 1/4" threads on. Other wise it just sticks out loads and isnt exactly secure.

I'd have that problem in the CPU block/RAD etc. Primarily being limited by a massive lack of time at the moment.

Hi Ricochet J,
I'm a data analyst at the moment. If stuff hadn't gone wrong I'd be doing a PHD in Physics now or Naval architecture. But thats lift.

Incropera is good, I'll take a look at Hewitt, Shires and Bott +Rohsenhow, Hartnett and Cho.

Physics books always make good reading.

I was a technical sales engineer, but I got fired for having cancer in January. So now I analyze data. Boring data but still, keeps the maths up while I look for something more permanent (and of course better paid).

As for the modeling, I was already down the 2d route. 3d is just unnecessary and given the turbulence in the pipes, largely can be ignored.

I'm working on all the thermoelectric loops at the moment. They're the more complex ones.


Still from the current flow rates, the pressure in the ram slots is good. Arguably I could use smaller ID tubes there to increase flow speed, but that depends on how good the Y splitters are. I'm already losing a lot of speed in the first Y junction.

Im also having to take into consideration the reduction in CPU loop speed that this change will have. I prefer the ram coolers being much slower flow speed than the CPU.

Its catch 22 with the fans.
While the front intake and top intake can be on full pelt, and barely make any noise as they're super awesome, the rad ones are different.
Turbulent over the rad means noise.
I've gone for sucking over the rad to allow for turbulent flow and with the blade geometry on the prop hopefully laminar flow from the exhaust of the fans. That should scramble noise.

A bigger problem at the moment is I forgot to put a bleed valve in, so once the case is filled, I'm going to have to rotate it to get rid of the air bubbles.
They're not big now (yay) but before when it was a closed loop the air all gathered in the right ram coolers and compressed so it was going no where.

how the hell can they fire you for having cancer? thats absolutely disgraceful, on the other hand, build is looking awesome, keep up the good work
 
Their claim was I lied to them on the medical they requested before hand, when the doctors thought I was cured. I was not (the docs screwed up reading the test results) so they claimed I lied to them during the interview process.

Probably completely illegal, but their loss.


Back to the build update.
These connectors are becoming a real drag, I'm trying to avoid replacing all the compression fittings and just making parts which will fit over the top. So now I have a blowtorch, and am going slightly off piste.

In the mean time I'm debating tidying up the second iteration & getting the graphics cards in now.

After moving into the new place, I'm now getting "Late CPU Initialization" errors and the mobo won't post.

Suggestions for what could have happened during transit?
PC wasnt knocked/dropped etc.
RAM hasn't changed.
There's no leaks.

The pc did boot, then BSOD'd with an IRQ less than blah blah blah error, which makes me think some ram has come unset.
The CPU is heavily held in place.

If the cpu's moved in the socket, then I have to drain my entire system & dismantle it... so help me out here, suggestions!

I would check all the cables are secure and in place properly before anything else, I doubt the CPU has come loose in the socket, they're in there pretty tight.
Also make sure your pump is still working, try with only one stick of RAM.
If all else fails then you'll have to strip the PC right back, rebuild it and if that fails then its time to start swapping out components to try and find the culprit.
Are you absolutely positive there is no leaks, even if there are no leaks now a drop of coolant may have leaked out during transit.
 
Checked the cables last night after a few glasses of wine. Couldn't see any lose ones.
Loose HDD cables wouldn't cause late cpu initialization and auto shutdown of the mobo before posting checks are complete though.

Can't remove ram without draining and dismantling all the system....
And if im doing that might as well redesign the piping.

Plus im at work now so can't check :/
Just sitting here worrying about my Behemoth. Its injured and im not there for it!

Yeah it'll post without a HDD but would just come up with a message telling you that a HDD hasn't been detected.

Watercooling has its down-sides and one of them is that it takes ages to troubleshoot a problem usually, still not much you can do until you get home, if you know the error code off by heart then you could research it at work (possibly) and try and find out what the common cause is and maybe a solution.

Hope you manage to sort it out soon mate :(
 
Cheers for the pointer
I've only encountered that error once in ~19 years (~3-4 months ago :D) twhen i ********ed up a few 2011socket pins.

Still. I suppose if i have broken the ram I cold get the new 8b sticks. My ramdisk always needs more space..
