You could probably invest in a 120.3, thin-core rad and low-volt the piss out of some high-pressure fans and get decent a performance/noise ratio.

Even though I don't want to invest at VapoLS-level, budget is really my last concern.
Noise and good temperature - these are my main concerns.
Temperature-wise I want to see *at least* the same I enjoy now: my 4400+@2.8GHz and Hydrocool measures barely over 40C when both cores are running over 90% load for 20+ hours (AutoGK is converting HD .ts to Xvid w/ full color correction) already.
Since after 3 years of service it's a little bit noisier than it used to to be and it seems somebody is buying my whole rig next week (i'm selling it for very cheap, solely because I there's no X1900 AGP and never be), I'm looking for some less noisy solution with the same performance.
Trevor has the right idea on the fans. 3 (or 6 in push/pull) on a 120.3 will give you and quiet operation. What I don't know is whether you can get what you want from a kit. Your application just screams for a custom solution.
Care to elaborate?I guess under 'fans' you meant fans for the radiator - but what type? If it's not essential, I'd minimize the number of fans, so I'd rather go with some slow-moving huge animal like some 25cm under 1k RPM...
Current OEM radiators come in two basic types: thin-core and thick-core.
Thin-core = Less surface area but able to work at their potential across a broader range of fan ratings. They're much less noisy.
Thick-core = A fair sight more surface area packed into a thicker unit. These require muscular, thick fans to function well. You can use less powerful fans, but expect to really pay in terms of performance. Surprisingly noisy with suitable fans. I have a spare 120.1 Black Ice Extreme that actually "whistles." I'm using 3x120mmx38mm Panaflo's. They're good fans.
To be honest being a bit older means a bit more lazy too thus I'd prefer some good all-in-one kit like the two external ones mentioned in my OP and let's tweak them a bit...
I understand, I've been around for a good while too. But if you want a cooler that closely tracks your requirements, it's best to build one. Once you get the brain-work out of the way it really isn't all that bad, especially if you working it into a new rig.

Oh I had the idea right away. Lots of WC people do so for quiet operation. Unless you use a truly massive radiator there is going to be a tradoff in terms of performance.

I see, thanks. So custom is the way... hmm...
Ah, it's clear now, thanks. How about getting some big radiator - presumably a bit ruther away from the machine - and putting one of those 250mm at, say 800RPM?
BTW where can I get some *big* radiator?
Yeah, I see what do you mean... it seems I have to invest more time into this prject.
But it'll be fun, I'm sure - and saving some money isn't the last thing to do either.![]()
So let me collect what I want to build: CPU and chipset for now (and probably the VPU later but I'm not sure about this one yet.)
Since I have no idea what kind of case I'll buy, I'd try to get a radiator I can put away from the case (ie on the floor under the desk, that's the coolest point anyway). Problem: If I do this, I'd either has to go with passive radiator or take care of its fan's power... hmm...
Q1: recently I read about dual-pump setups - what's the deal with this?
Q2: thick pipe or thin pipe - does it matter (apart from the fact that water flows faster in a thin one)?

I just skimmed a review of the Symphony, and for a TT product I have to admit that I'm impressed. The temps reported in the review were on the high side and don't, IMO, qualify as high-perf, but they're pretty good. If quiet is your goal, the Symphony may be what you're looking for.

This is a good place. Try http://www.thermochill.com/">this</a> place to learn about the best OEM rads on the market. From what I understand, the PA series is sterling.

As projects go, I find designing and implementing a water-cooler very rewarding. As for expense, well, it MAY not be cheap. It depends on what you want and how you want it to look.
So let me collect what I want to build: CPU and chipset for now (and probably the VPU later but I'm not sure about this one yet.)
If you're going to include a GPU block I'd suggest doing so right at first. Shoe-horning one in later creates its own problems.
Since I have no idea what kind of case I'll buy, I'd try to get a radiator I can put away from the case (ie on the floor under the desk, that's the coolest point anyway). Problem: If I do this, I'd either has to go with passive radiator or take care of its fan's power... hmm...
Case metrics for a water-cooler are very important. I went the chicken route and bought mine from a place that cut the case to my spcifications before I even saw it. The Symphony is starting to look better and better for your application.
Q1: recently I read about dual-pump setups - what's the deal with this?
The reason for using a dual-pump configuration in my case was twofold:
1. I use one of the most restrictive CPU blocks (a review of it here) currently on the market and wanted to make sure it wasn't starved for pressure.
2. Since I have a 3-block loop, a hefty rad and a fair amount of tube, two pumps (in series) provides enough flow to keep things moving at a brisk pace.
Beyond these I wanted an in-case solution.
Q2: thick pipe or thin pipe - does it matter (apart from the fact that water flows faster in a thin one)?
You mean internal diameter of the tubing? Well, the jury is still out on that one. In general, larger ID has better laminar flow (the "sweet spot" right down the middle of the tube) which allows for better coolant velocity. This helps a lot with impingment-style blocks. If, however, a block is designed for low-velocity operation, you can easily go with smalled ID tubing, though I wouldn't consider anything smaller than 3/8 inch ID. Thinner tubing is also a bit easier to plumb.

What I'm thinking about is some automotive part w/ a 200-250mm fan at ~600RPM - is this totally crazy or just a question of time and energy?
I'm also toying with the idea.
Sure. In my case I have some flat and fairly large Ikea desk (the suspiciously-named Jerker or whatever its name), so I can hide everything...
You're right, of course. Even if I don't apply it, it can be there, in the loop already.
Dunno, I'm having problem finding a good midi case... I want not only tool-less but specifically latch-based card slots, an easily accessible side panel like the TT Tai-Chi has (it opens towards, not from the back), no cover plate or opens from the side panel's edge, front or side-panel-edge I/O ports (no top or other sided edge ones) - these are my basic needs. I'd prefer a see-thru side panel but it's not that important, just like multi-thermal zoning would be nice but not a dealbreaker if it isn't there... same goes for future BTX compatibility.
Dunno, maybe it's just me but I think when you do have the option to take the heat out of your case easily it's kinda weird not to do it and cool it outside, (unless you're short on space, oif course.)
Another crazy thing I'm toying with: how about oil cooling? I mean not submersing but using oil as coolant: oil pump with an automotive radiator I mentioned above? Is it very noisy?
I see, thanks. In case of a "thick" tube you may can spare the reservoir if the tubing is long enough, right?
Another question: I read a lot about that Swiftech Peltier-based WC block and sounds interesting... how much would this Peltier help?

Just trying to adapt my perspective.I'd consider my water-cooler high-perf, but it ain't nowhere near quiet.

A man after my own heart.
You're right, of course. Even if I don't apply it, it can be there, in the loop already.
Another functional way to prepare would be to just plumb lots of extra tube after your CPU block.

That's some feature list, and all things I'd like to see in my next case. What do you mean by "midi case?"
Dunno, maybe it's just me but I think when you do have the option to take the heat out of your case easily it's kinda weird not to do it and cool it outside, (unless you're short on space, oif course.)
This is perfectly reasonable, though many water-cooling people don't see it quite that way for some reason.
Another crazy thing I'm toying with: how about oil cooling? I mean not submersing but using oil as coolant: oil pump with an automotive radiator I mentioned above? Is it very noisy?
Noisy? I doubt it. What you'd be loosing would be the superior heat capacity of simple, unadulterated water. Even the most highly-rated water-cooling additives decrease waters natural ability to pick up and move large quantities of thermal energy. This isn't to say that your idea has no value, only that it's going to be difficult when you take things like block\pump design into account.
I see, thanks. In case of a "thick" tube you may can spare the reservoir if the tubing is long enough, right?
Conventional wisdom says that shorter tubing runs is better, but in my experience it doesn't matter much if you have a powerful pump, which is advisable in any case. As for whether you should use a res, I think it's a matter of pros and cons. I like the idea of having one plumbed for ease of fill & bleed, extra coolant and a place that allows the efficient stirring of water and additive. However, T-lines have their benefits as well. 6 of 1, half dozen of another.
Another question: I read a lot about that Swiftech Peltier-based WC block and sounds interesting... how much would this Peltier help?
TEC units are, IMO, a bit TOO extreme. If intensely low temps are in order, short of something like phase change, a peltier-based cooler is the way to go. For me, though, the extra potential danger, large power requirements, not to mention having to technically ruin a mb and CPU, just aren't worth it. My last water-cooler (less than half the capacity of my current unit) kept my box running with a 106 degree ambient. That's good enough for me at this point.
If you're interested in TEC's, you might want to take a look at this. The previews are sterling.

Mid-tower: neither full tower, mini, micro etc.
BTW I think I found one: Enermax CS-718 aka MaxFlow - it's almost perfect, most likely it'll be my next case...
But I've seen that silver block at DD... does it worth the high price?

Not much in terms of performance. The Storm v2 (I have a v1) is a true impingment, "cup/jet" block that requires a fair amount pressure to function well, so it's restrictive to a high degree.
The v2 has has channels that supposedly make it a bit less restrictive.
The Apogee is a modified "pin/grid" blocks that isn't as restrictive and should function almost as well without the micro-jets that the Storm has (which can clog if you're not careful with your coolant).

Not inherently. It depends on the pump. My twin 655's are very quiet.

Yes, but the blocks aren't THAT different, though. I'd still suggest a relatively powerful pump.

1-2c, if that much. I still can't easily translate between celsius and fahrenheit, sorry.![]()

Be patient, eventually there will be. Cooling tech WILL march on.
