What's the coldest liquid temperatureanyone has ever run though a Koolance CPU-330?

Ok. So now I have everything except my radiator(s). But I have an important question. I went into Lowes to purchase some parts. I came out with 10x #8 hose clamps and 2x 1/2" > 1/2" barb (splicer) fittings. Essentially, it is a (symmetrical) double-ended 1/2" barb fitting. But the thing is, it's brass. I just want to know if that's a problem or not. I couldn't find anything else to do what I want. I intend to expand two (1/2") holes in one of the air vents on the back of my server, and pass my coolant lines through them. Actually, these double-ended barbs (splicers) will fit in those holes. They have a lip at the halfway point between the ends of the splicer. So the idea is to pass both units into the case from the outside, allowing the lip in the middle to keep the units from passing all the way through. I then intend to secure the barbed splicers in place, by attaching the inside coolant hoses to them. The face of the hoses on the inside will hold the splicers in place (with the raised lips against the outside of the case) by the hose clamps on my inside hoses.

But I need to know if there's going to be a problem with corrosion due to dissimilar metals being used?

BTW. I also purchased a gallon of denatured alcohol to mix with my coolants. Most of the water that is present, will be diluted just enough to keep the coolants from being flammable. I think I have enough other ingredients to make everything perfectly safe. So how much corrosion would I expect from a very strong antifreeze solution?

Speak up folks!

ps. I really have to tell you guys, this looks very cool (pardon the pun) with four Koolance CPU-330s on the board, and using 1/2" ID heater hose!! Just too damn cool!!

I should get an award for the slowest @$$ person on earth. Chalk this up to procrastination or just simple fear. After spending all that money on my setup, I then got scared that I might have screwed something up, only to find out the board was damaged by my actions.

Something that I noticed while coating the board, was that the liquid I was using had siphoned (by capillary action) up into the memory slots. I think I removed all of it, but I kept having to do it until the thing dried. In the future, I will seal the area around the memory with fingernail polish, so as to guarantee that can never happen again. Then I would apply my sealant.

I was having to apply the sealant with a brush, since the components are so cramped together on that board. It's literally only 4 processor sockets and 16 dimm slots. It does have one and only one pci-e. But if you look at the board, you'll see that it's very demanding on one's attention to detail. I never realized the liquid I was applying would siphon up into the memory slots. I do now, and won't make that mistake again.

So, maybe some of you will understand my fear to finish it. But I have now set out to do just that. I am buying my radiators today or this week. I only need to find a reservoir now.

Ok folks. I've finally done it. I went ahead and brought two of these as my radiators.

B&M 70274 - B&M SuperCooler Oil Coolers - summitracing.com
Perma-Cool 15156 - Perma-Cool Hose Barb Fittings - summitracing.com

Yes, most of you probably would never have considered doing this. But the sheer size of these things and the efficiency of their cooling capacity made me consider them. That and the price was also convincing.

I ordered the fittings for these as well. The fittings are 1/2 inch male NPT to 1/2 hose barbs. I don't think there should be any problems here. At some point in the future though, I may add another pump to the loop.

Well folks, I now have my radiators. As goes with life, I have (had and eliminated) some questions that arose after making my selection. I came across further details about how these B&M Supercoolers are supposed to operate. Now since they are nothing more than aluminum radiators, I didn't think anything would be "hidden" in their design. However, there's some mention about the viscosity of the fluid influencing the amount of flow through the device. No need to worry! I just tested the flow through the device, and it works just fine. Without any pressure, the flow is complete and free.

So now I'm up to installing the radiators and setting the system up. I'll stop here and post more later.
