A major upgrade is on the horizon, and I started considering water cooling to get a nice quiet system. First I looked at the reserator and thought that'll do, then having read a bit more, it looked like it wouldn't cope with a decent cpu and dual graphics setup. Having read more, shifted to the swiftech H20-220 Apex Ultra. It doesn't come with gpu blocks, so started looking at what to do there, reading around more. Now at the point where I've nearly convinced myself to go fully custom. Might cost more and be more complex, but I'm happy to buy quality as I would like a system that will last me a good 2-3 years without too much in the way of major upgrades.

The Swiftech Storm seems to be about the best cpu waterblock around, but it seems to rely on having decent high pressure flow. So a pump like the MCP655 would do nicely. Would having a loop with these two and say 2 gpu blocks (and res with probably a 120.2 rad - maybe a Thermochill PA) affect performance drastically? I'm looking at using it to cool an 6600 conroe (hopefully OC'd a good bit), don't know which gpus yet. Would it be worth setting up two loops? If I were to go w/c all the way and add a n/b block and perhaps hd coolers how would that affect things? If I'm going to get a Storm I'd like to get the best out of it, and the more components in the loop the less well utilised it would be according to the articles I've read.

One last question while I'm here - if I were to run a single loop would a PA120.3 be worth getting over a 120.2? Looking at comparisons available it might get you a few extra degrees, but is it worth it?
 
Storm is a great block although it's getting hard to find. If you can fit a 120.3 in your case the extra surface area allows slower, quieter fans. The MCP655 is a great pump although some have complained about noise. I have a 350 which is silent and there are special version of it with built-in res and extra performance.

As for the loop, there really is no big deal with having the whole lot in a single loop. The water leaving the cpu block is only slighter warmer than when it went in. The overall heat delta between leaving the rad and entering the rad is surprisingly low. We're talking probably less than ten degrees between the water entering the cpu block and leaving the last gpu block.
 
That sounds good, some of the stuff I'd read suggested that having too many components in the loop can reduce how well blocks like the storm perform. I guess if you have pump -> cpu block then this is not a problem. Time to find a storm then...

The old D4 is slightly noisy / amnnoying, the D5 is reported to be even quieter as is the new D4 and D5.

How can you say the temperature input / output for the rad is small but then say the Delta is less than 10c in a loop? The Delta in a loop is 1c at most. The Delta between water and ambient is 10c at the very best!
 
a 120.2 should sufficiently cope with a GPU and CPU especially a PA, my BIX can cope with my CPU and GPU. But if you have the space in your case for a 120.3 then there is no harm in getting one will knock 2 or so degrees off :) but thermo PA's are huge rads so may end up externally mounted pending on the case, HD and northbridge coolers arent really worth paying for, hard drives dont get that hot anyway and northbridges can just have a silent cooler stuck on them

So the delta is less than 10C which is what I said. I didn't want to set any expectations and I don't know enough about his flowrate, blocks, heat inputs, etc. to be able to quantify the exact number. And I made no mention about the delta between water and ambient.

Estimating numbers before the rig is built is impossible. There are way too many variables to state with any confidence what deltas will exist anywhere.
 
I've got a much neglected PC70 that has been sat in a corner since I went SFF which should do the job space wise (although I might be tempted to go for a newer case that takes 120mm fans as standard) . As for north bridge coolers, I hadn't really planned on getting one anyway, but on the hard disk front I am thinking about running at least a couple of raptors and have seen some relatively well priced hd coolers.

Set the dremel on the PC-70 for 120mm fans front and rear, takes about 20 minutes tops.
