Glacial

[Risky]

Well this project has been going several years but since its vaguely close to something near completion I thought I throw in a few posts.

Gettting Rpm of three fans and one of Starbuck3733T's fine Max1668 units has got the cable menace going again, I'm afraid.

I've got a few oddments comog in soon so expect this to get a lot more complicated soon. I'll list out what's in there tomorrow and start to turn this into a decent write-up. However the cooling is working and keeping a 2.8Prescott at ~40C under UD load with the fans down to minimum voltage.

Hi

I think the first thing thats going to put your case looking a whole loot more scweeter is putting rounded IDE's in.:cool:

The huge ammount of fans etc you have in there makes it look rather like spaghetti junction, and beleive me, i was their once, but now alot is hiden behind the MB tray and ive cut/lengthened appropriate lengths for custom molex's to fit to each device:h34r:

I would say completely remove the psu and start braiding it unless your going even more custom!:blink:

Anyway i dont quite understand your watercooling setup but i think it would look alot nicer with less of the brown fixings :confused:

Hehe sorry for moaning i do like it really :) esspecially the way you can keep a prescott that cool!!

hehe, when i first saw the photos i thought ... Risky's cables were neater than that! .... ooooh hang on whats that cable going to the NB .... aahhh one of star's SMbus doohickies..... coool :cool:

Where is your step up transformer for the AP1500, i cant see it anywhere! Fancy giving us a clue about your "odments"? sounds interesting :)

[Risky]

Well lets explain the mess:

THe ide cable are only for the Optical drives and are folder and hidden top right. The ribbon cable accross the bottom is from the PCI card for the RD2 PC Geiger (http://www.ioss.com.tw/web/English/RD2PCGeiger.html) - this one could be folded but I need most of the lenght so it has to stay pretty much as it is.

Now to explain the setup:

Watercooling
The cooling contains:
Asetek Antartica cpu block
Alphacool AP1500 pump (on 12V while I finish my PSU mod)
Asetek 'original' waterchill radiator - modified to take pushfits
Innovatek Fass-O-Matic resevoir (at top out of shot)

The tubing is clear Legris Flexible poly-etc 10/7m exchept from res to pump to rad which is nylon 12/10mm. I'm taking adavantage of the multiple res connections to run the dual outlets seperately to the res. The fittings you can see are brass SMC KQ2s on the rad w ith norgren compression fittings to provide the thread. The eblows and Ts are Norgren Stainless Steel but show a little brown form reflection in the pic.

The T gives me a drain line with a valve. The advantage of the Norgren T fitting is that it rotates freely so I can drop it to drain off the system. Iam going to add a second t line and two more valves (like a fill/bleed setup) so I can loop in additional blocks to leaktest when I need to. (parts arriving today!)

Pump
The pump PSU isn't in place yet. (I'm just using 12V). I need to break out my soldering iron to do it and I'm feeling too knackered in the evenings to do that without maiming myself. THe psu is a bit too big for this rig unless I rehouse it so I'm going to have to velcro it to the back of the case and run the control lines across the case (yes more lines).

I want to get one of my front panel LEDs to show pump ower on and I'll tap the line for voltage measurement while I'm at it. Phase 2 of the pump project will require a current transducer to measure the power consumed.so I'll have to cut the supply cable and make a small pcb for all that. (If you know anything about current transducers please throw a reply to my post on BiT!)

In the meantime I think I'm going to show the voltage on an analog meter I have handy!

Stray cables

The messy bits are mostly down to the fan and temp sensors. I mighttry to route these a little but to be honest it hardly matters.

You might have spotted the huge grey able bundle across the bottom of the case. This is to reroute the three channels of audio to the front panel and back to the rear (pass through sockets from FrontX) I've got theose Zalman 5.1 headphones and would rather plug them in at the front.

There's a three channel can controller in one of the 3.5 bays which is why the upper HDD isn't in the whole way and I've actually got 4xUSB and 1xfirewire at the front without too much mess this time!

Core Hardware
Asus P4C-800E Deleuxe i875
P4 2.8E Prescott
2x512Mb Crucial PC400
Radeon 9600XT (to be replaced with 9800Pro w/c with Alphacool NexXxoS GPX-A when it arrives - I have a asetek block on it but I can only afford to lose 1 PCI slot)
SB Audigy2 ZS OEM
VisonPlus DTV card (bargain at 40+VAT - all freeview channels)
RD2 PC geiger bus monitoring card and Drivebay unit
Adaptec 2410SA PCI SATA Raid 5 card
4x Maxtor 120Gb SATA (two on order will be 3 disk Raid 5 with hotspare)
Sony DVD
Sony CDRW
and ye olde floppy drive (which I actually needed!!!!)

Case

Its a GlobalWin 802 - (Classic case?) with a few years hacking, namely:

Sides, top sanded to bare metal
Plastic front bezel romoved
Drives slid back flush or close
Bulgin switches for pwron, reset
Front 120mm intake
Fass-o-matic in roof of case
overloaded castors (botch, tbh)
side 120mm fan (will probably remove and mindow at some point.).
Front 5.1 headphone ports.

:eek: crowded!

[Starbuck3733T]

Most definitly.

I think i see something familiar.

[Risky]

Forgot to say, "Glacial" refers to the speed of construction rather than the temps!

Regarding "Crowded" - thats the design concept - take the case I had and fit as must hardware as physically possible. I'll try and keep it as tidy as I can but its not going to look like a rig with just a video card in a PC-75!


Starbuck3733T, the little fellow is working very nicely. I'm going to have to do some work to get more usefull sensing. I think I'll mod one as a water temp sensor. Should fit nicely in a drilled out plastic 10m plug (The ones I have (SMC, Norgren, I can't remember) are mostly hollow so I should be able to drill out and seal with araldite (as I have it to hand). Pic attached.

[Starbuck3733T]

you'll get the best temp results with the top of the transistor casing exposed to the top of the water. Thats the way mine is connected - casing is Goop'd into my reservior. The aldralite acts as an additional thermal transition and your sensor won't respond as quickly.

[Risky]

Will do. Might even get on with it soon. I'm buying a G1/4 res sensor to connect to the boards, third sensor and I guess I'll have this one after the rad.

Between this and my bleed/test fittings (later) there will hardly any tube left in that line!
