Waterchiller build
41 - 60 of 130 Posts
Thanks guys,
ok, small update time,
I mostly finished with the cork tape insulating around the motherboard. Takes quite a bit of time around those MOSFET's, attention to detail here can save your board. Next, I need to work my way around the power MOSFET's, the more difficult part, they are currently being covered by a stock heatsink. I'll probably take that off and order some new ones, and use some sticky thermal tape to attach it. That's still in the books, but next up, I will be using silicone for an airtight seal around some of the capacitators near the CPU, seal off the northbridge and seal off the ram sockets and the PCI-E socket.

lol I know, it actually feels a lot like gum, and works like gum. It really isn't to difficult, just time consuming, and sometimes anoying when it comes to those small cracks. Just wait till we get to the CPU socket, then the delecate/hard part comes, expecially for my board, with the pins in the motherboard

That prettyness factor will jump when you see the temps

I'll see If I can get the silicone on before too long so I can give you guys another update, unfortunatly, I'm in the middle of reading Ken Kesey's Cuckoo's nest for school.

but I guess when you computer run at sub-zero temperatures you can show off with that

Ok, so tonight I compleated the front side of insulating my motherboard (- CPU)... I had to use silicone on the capacitators to give them a watertight seal, this protects the connectors from condensation and possible corrosion. It's messy stuff, but it's much faster, and better than using the cork tape, expecially in those small, hard to reach areas. Boy, I'm burned, I got a lot to tackle comming up.
What's next?
1. Insulate back side of board using more cork tape, and foam tape for added protection
2. Order a Heater for added security
3. Work on the CPU (dielectric grease + airtight seal) and fitting in the waterblock.
4. Sleep until my pump arrives (thanks lando

I'm open to any questions you may have.

lol good question..
Well, I still have to do the following
1. Order the condensation heater (maybe by the end of the week because I am ordering some custom ones)
2. Wait for my water pump to arrive
3. Insulate my waterblock
4. Install the heater and inulate the back of my motherboard
5. Insulate my accumulator so it doesn't crack
6. Insulate my waterpump from frost buildup
7. Insulate all my tubing using the stiff celled tubing insulation and pipe wrap
8. Get the right ratio of de-icer and watterwetter correct.
9. Pressure and leak test the system
10. Post a lot of pics on my backup 700MHz mac w/64 megs of ram and intagrated gfx. (the longest part)
11. Start to OC and get some 5GHz results....
So for time estimations, Mid next week, you will see my waterblock covered in ice, by the next weekend, I hope to have my Heater in, and back of the board inulated, and by 2 weeks from now, pressure and leak tested to profection. Not to mention I still am looking to buy a raptor..
for temps, a safe guess on temps would be -20c idle and -10c load, mabye lower if I decide to mod the setup. My goal is to get better temps than the OCZ phase change system when it comes out

Dude, don't insulate the pump.
If you insualte the pump it'll melt because it can't dissipate any heat.

You need to insulate the connectors, otherwise they will freeze over and crack, causing major problems to the pump. I won't insulate the back side so it can breath

Hadn't planned on using anything, the dielectric grease and all that crap will be overwelming.. mabye the ceramique, or the stuff they use on the vapo kits.
Edit: This is what i'm talking about Tuchan link

All I can think to say is you should pass around the hat just for the information and excellent, HOW TO DO IT YOURSELF GUIDE?
I got to say your Nickname fits you well I only wish I had your vision, drive and ambition. Good going wowsa!

Was this the reason you were thinking of trading your 640 for a 550?
There are a bunch of us that are following this thread very carefully in anticipation of its functionality, Cant Wait for results!

Yes that is what I am talking about. My chiller failed because of two things I am thinking. Firstly I didn't have the correct paste to seat the very cold block on the cpu with (coudn't sourse it but have since), I think the As5 was just not coping with the cold and 2: I wasn't using enough paste. I have learnt to use more with my particular block, especially when I am running the TEC. The clamping pressure you apply on the cpu will also make a difference to the point of even 10C. When my block is too tight it seems to squeeze all the paste out and underperforms. Loosen it off so I can just wiggle it a little and it seems to be happy. That applies to only using water for cooling, no chiller and no TEC.

@ Oknlip, I might turn this thread into a guide / sticky so I can help other's with their builds (if anyone dares

) and then add in some basic information that will help the general pub. to understand what is going on.
The main reason why I wanted to trade processors is, because the 640 is in my bro's rig, and he is an anti OC dude, so a faster stock processor would probably be worth more to him. (640 = 3.2, 550 = 3.4). Of course, I am going to be using my Presler in this setup, my goal is 5GHz which should be possible depending on the motherboard droop. If the droops bad, then Lando95 will get another vdroop order from me.
@ T, yes, you have to use a ton of dielectric grease, silicone, about 5 in of padding around the block, and for saftey, a custom made heater that I talked about earlier to evap away the frost buildup. (takes 2 weeks to manufacture, but well worth the wait IMO)

If you insulate too much of the pump it'll just melt the plastic.
I'm going to be building a water chiller soon, i've just bought an FR85CL and i'm gonna get some R404a, it's a bit expensive so i might have to use 290 but it should hold -20c idle if it all goes to plan, then i might even try and build a cascade water chiller or i could convert it into a DD SS/C.
I look forward to seeing your result's though.

i really dont see teh point in making a cascade water chiller, you have to let all the gas out of the compressor anyway, why not just make a cascade phase change system. and if you do make a cascade water chiller, it would be very hard to find a liquid that didn't freeze at evap temps of around -100C

nice, I look forward to seeing your results!!! that R404a ain't going to be cheap, that's for shure. I don't have the guts to cut into my chiller, R-22 is good enough for my uses.
@ R, Pure Denatured Alcohol freezes at -90c, so I'm sure you could probably beef that up a little, and add some anti-corrosion properties to it, but it's really all about the propane

Well, I will be gone monday through friday next week, college visits. I will get the insulation on the accumulator done by tonight, and then start on building a nice little box to house the whole chiller in (fans and all). I am getting a bundle of parts in by next week, so I am waiting for those to arrive before I can get much more done. Not to mention my custom heater I will be getting, takes 2 weeks to make, so I got some waiting to do.
I have followed your work WOWSA, and I think it looks really good and promising.
I have a Q about a waterchiller idea, that I have been fumbeling with in my head. I know this is kind of your treath, but I think it falls under it.
Here goes:
I asume you use a really powerfull A/C unit, because you want your fluid to remain at a constant very cool temp. Could this be done with a smaller compressor, say one from an old freezer, if combined with a larger amount of fluid to absorb the heat?
I guess that what I really need to know is, what are the relation between the A/C units BTU output, and the heatoutput from the CPU.
Reason I would like to go that way is, that I could make a system that don't say no more than a fridge then.
Well .. keep up the good work.

Skipper
