Thanks for the replies! I'm currently designing the wc chamber, but it is getting really complex. I want to get it right the first time; this much acrylic will cost a bit and the time taken to bend/bond it is going to be immense. So I've decided I should test the plumbing in a ghetto-rig first. fut, you're right, I can't use an aluminum rad. I thought I could get it anodized to protect the system, but anodizing the inside is going to be too tough. And since copper is better anyway, well, I'll just make a pretty aluminum shroud for the thing and get that anodized
. As for the issue of the cpu not getting the coldest water possible, I'm hoping that a tall resevoire will help with that. I expect to get a layering effect of water due to differing temps. I'll pull water from the top of the res. to go to the radiator, and water from the bottom to go to the waterblocks.
Using the hydrothruster is a no-go, as it is an open motor design and is just too damn big. I picked up a big heater core from autozone this weekend. It's ugly, and will get uglier when I mod it, but it'll fit 2 120mm fans (I'm going with the push/pull you suggested, Una.)
I'd like to get some decent data out of this, so is there anything I should incorporate into the plumbing, such as ports for temp sensors (sorry if the terminology is wrong)? Also, what cpu waterblock would you reccomend for this setup (I should be able to get high flowrate for it)? Thanks!
