Finally!!!

[Turbokeu]

Yeah people, after about two years (since June 2001) my watercooled PC-70 is finally operational (in test phase anyway)...
I already told it several times, but my own company, KD Computing Services, takes most of my time...

I'm quite satisfied with the results for the moment, taken into account the age of most of the parts (radiator, WB, mobo...):
Asus A7V333 Raid with XP2400, softly overclocked to 2250MHz@standard 1,65V and 1GB of PC2700 DDR (although I could reach easily 2500MHz@1.85V on aircooling with this CPU).

Still lots of finishing work to do but I can see some progress...

As usual, some pics:

Mounting of the Danger Den GF4 block on my MSI Ti4400.
As usual everything in hardsoldered 15mm copper tubing.








15mm copper inlet and outlet on my Maze3 WB (the long outlet has been modified afterwards with pieces of Tygon tubing to prevent torsion from the Maze3 onto the CPU).





PS: All pics are hosted on my Skynet webspace for the moment, we are migrating our IIS-server at KDCS to Linux-Apache, and I don't have FTP access from home for the moment...
(www.turbokeu.com is hosted on the webserver of the company)

To be continued...

Connections between WB's and copper tubing are sealed with this product:


Settings of the XP2400 (1st week 2003 AIUHB).


Motherboard Monitor Dashboard Idle (Ambient temp=25.5°C and Panaflo M1A radiatorfan at 6.5V)


Idem 100% CPUload with Prime95 after half an hour.

Difference between radiatorfan at 6.5V or 12V is merely 1°C...
Watertemp is measured with 10K NTC in my airtrap (and connected to mobo) and fishtank termometer for calibration.

To be continued...

Overview: Please note that finishing isn't done yet.
I have blue dye lite from Becooling but I ran the tests with the rest of my old coolant mixture with green dye lite + Purple Ice.


Airtrap with 10K NTC resistor in waterflow for tempmeasuring of coolant (upper arrow) and cable to JTPWR-connector on mobo (lower arrow), and fishtank termometer in the coolant.


Lower arrow indicates my Swissflow SF-800 digital flowsensor connected to the outlet of the Eheim 1250.
Upper arrow indicates the cable with the output signal to my digital flowmeter cicuit.

I bought some (25 pieces) blue rectangular leds in the US...


To replace the red leds of my radiator fanregulator and voltage monitor.
Before:


After:


Meanwhile I connected also my Seetron SGX-120L grafical LCD...




And the digital Swissflow flowsensor too...
Waterflow is 4.39 liter per minute (variates between 4.39 and 4.41 liter/min).
Seems a little low to me, but is probably caused by the flow restriction of the cube-style radiator, and the flowsensor itself whose ID is 8mm (the rest of the circuit has an ID of minimal 10mm and the total length of 1/2" Tygon tubing is less than 1.20m (four inches)).
I still have to set the CPU speed indicator to the right speed (actually 2250MHz)


Overview of the electronics:
Digital flowmeter on the left, CPU indicator on the right, on the lower right the Seetron LCD, and on the left of it (not visible) my radiator fanregulator and voltage monitor.

Do not pay attention to the cabling spaghetti, has still to be finished...

you just now got stuff in there?? better late than never i guess lol

nice and clean just as befor. i await the final pics

[JokerCPoC]

Yeah Me too, That's cool, The plumbing kinda looks like a plumbers worst nightmare, But as long as It works and You like It, That's Ok by Me. I just hope It gives plumbers nightmares.....

[murray13]

I like it! You spent a lot of time thinking and working on this project.

Can't wait to see your next one...2005 maybe???

Just kidding...nice work!!!

Hey Turbokeu, looks very nice!

BTW, is your ICL7107 Thermometer circuit finished yet? I'd like to build it for use with that Swissflow flow meter.

In fact that nightmare works quite wel...
I can fill (and empty) the system in a couple of minutes, bleeding is done by the airtrap in less than an hour, all turns are 20mm PVC or 15mm copper.

I thought they were discontinued?

I like it too, maybe not as performant as a heatercore, but easier to integrate in a case, very compact and it has no problems with air pockets in the prechambers as the rad is made of two 3/8" parallel copper tubes of about 5 feet.

Some advice: Put the fan on the opposite side of the rad (sucking through the rad) and with a shroud of at least one inch between rad and fan (less fan noise and better airflow, the death spot in the middle of the fan is further away from the radiator fins).
Also, try to install a duct on the other side, so you feed the rad with fresh ambient air, not "hot" air from the case.
(See also the pics on my webpage)
Beware, there are about 160 pics on that page! (didn't have the time yet to split it in several pages... )

Have fun with your AquaCoil II.

Thanks,
Did you acquire a Swissflow sensor too?

In the meanwhile I decided not to make the ICL7107 thermometer because:
- I already have onboard CPU socket temp and CPU on die temp readings (Asus A7V333).
- I used the A7V333 onboard JTPWR connector to measure the coolant temp through a 10K NTC in my airtrap.
- Initially I planned to convert the 50-2000Hz signal from the Swissflow SF-800 flowsensor through a National LM2917 (frequency to voltage convertor IC) in a proportional voltage to feed the ICL7107 voltmeter, but since that causes conversion errors (digital to analog to digital), I decided to go the digital only way.

This is why I conceived a frequency meter based on the all-in-one National 74C925 4-digit/counter/latch/driver/multiplexer IC.
See schematics and PCB layouts here.
Initially I used the three most significant digits to display 00.0 to 99.9 liter/min on the display, but since the actual flow is less than 10 liter/min (actually about 4.40), I changed the schematics and PCB layouts to display 0.00 to 9.99 liter/min (3 least signifcant digits of the counter).
Beware, this modification is not yet updated in my flowmeter page !

Nice, very nice!

How much did that SwissFlow meter cost you?

[JokerCPoC]

Nice, Doesn't even begin to cover this creation, That's fantastic! I wish mine would look half as good as this one when I get all the parts and get It working.
Wow!
right now I only have a few parts:

MaxXxpert Radiator 3/8" connectors $30.00 @ ebay, Free shipping.
D-Tek Drive Bay Reservoir 3/8" connectors $25.00 @ www.case-mod.com/
10' of 1/2" OD 3/8" ID Clear Vinyl Tubing $5.00? H&E Hardware
12 Hose clamps $1.00? H&E Hardware

My Shopping List is like this:
1. 120mm*120mm*38mm thick fan (cheap) to use as a shroud (I know It's a waste of a good fan, But, It's Ouick),
2. UNI BF-1 Bulk Filter Foam - Green Fine Foam. Size: 12" x 16" x 5/8" thick (Needs Support from a Fan Grill) $??.00,
3. 90 degree duct (1.75"x6"x5") and a hole in bottom of My case,
4. PCI Relay card $28.00,
5. Eheim 1048 pump $80.69,
6. Gemini Cool Water Blocks (Cpu, Gpu, NB & SB) about $120.00 or so.

My Radiator is in the front of the case so It will dump inside the case, Which since I have Pyramid V Temperature controlled fans (3-120mm and 1-80mm) possibly means I need a better case or I need to vent (Duct Tube or Box Vent? That might work.. If I can keep It short.) the warmed up air out the bottom of this small (17"x17"x7" or 425mm*425mm*175mm Internal dimensions of My) case.

7" length for Duct+Fan+Shroud+Radiator.

Edit: I may need a new case anyway, My last 5.25" drive bay of 3 is useless for anything longer than about 6" due to the case being so short.

Thanks for the info Turbo.

I have an invoice from Swissflow for the SF-800, but I don't want to actually pay for it until I know I have a solution for the electrics (BTW, the meter is ~$75 for me in the U.S.). However, I am electronics challenged (my background is mechanical) - I can put a circuit together and do basic troubleshooting, but need a circuit like yours to start with.

I was looking at your ICL7107 circuit because I liked how you could switch between the different readings all on one display. Would it be fairly easy to add this cabability to your 74C925 flowmeter circuit? I noticed that the two circuits interface with the 7-segment displays differently - one through the ICL7107 and the other through the 74C925 - and I don't know how to go about using the 74C925 circuit and still be able to switch between the flow and say the water temp (and others). Would this functionality be fairly easy to add to your 74C925 circuit?

BTW, here's a link to the thread I started on my project. I just posted two updated images at the end of the thread:

Your idea seems well thought, and I liked to see it in practice.

BTW, you're lucky... I paid 127$ for that swissflow about two years ago...

Temp sensors, whether they are NTC resistors or silicon based sensors like the KTY10, are resistance based, through a voltage divider they put out an almost linear voltage.

My 74C925 flowmeter is basically a frequency counter, it counts pulses (coming from the swissflow sensor).

If you want to measure temperature with the 74C925 you will need a voltage to frequency convertor like the National LM231/331 and calibrate it for the right voltage to frequency conversion.

As you see it's perfectly possible but I didn't dig it deeper...

How's that case holding up? I'm looking at the PC-71 and I was worried about the weight possibly bending the aluminum. I just wondered if it would stand up to being carried around to LAN parties and the like. I can't really tell how much mine weighs since the case (an old Chieftec Dragon) weighs so much to begin with.

Also, how heavy is it fully stocked? Mine's so incredibly heavy I dread lugging it around.

-Nice work by the way!

[trit187]

just in case anyone is looking for the rad, xoxide has a maxxpert one which looks fairly similiar to this one for $30, http://www.xoxide.com/mara.html

and if your looking for a small watercooled lan case check out this guys, managed to fit it all in a PC-60

Thanks,
The empty PC-70 weights almost nothing.
As it is for the moment (only one CDrom, one HDD but WC completetely installed) it's very heavy, but nothing is bending.
It's big and therefore not easy to transport.

That's cheap!
It's only a pity that the tubing is 3/8" OD and not 1/2"...
The Aquacoil II has two times this number of passes (two parallel 3/8" copper tubes with 1/2" inlet and outlet).

Very nice job Turbokeu. I am in the proces of redoing my PC-70 too. I ducted my radiator to the MB case side instead of the top. Mine is fairly full with a water cooled dually, two SCSI hard drives and three SCSI CD ROM drives (burner, ultraplex and DVD). Weighs in at 53 pounds.

[trit187]

anyone know of a place where you can still pick up The Aquacoil II radiator?
