Watercooling plan

I've resisted h2o for a long time now....but it is on now.

I'm going to make a small upgrade in my 2nd computer (KD7-Raid, 1900+) to (2400+ Mobile and Nforce PRO) to tide me over until 939 a64's are available. I'm going to get a new case, I plan on keeping my old system intact (basically because I have so many SCSI devices in it, I can leave it as an mp3/data server and move the good innards to a smaller/newer case). The case I'm planning on getting is an Enermax Titanium with dual 80mm exhaust (I like 120mm better...but I love this case).

Here are the options:

1. One heater core that the two rear 80mm fans can be attached to
2. Two heater cores (each capable of attaching to an 80mm fan...even if it isn't to the rear 80mm fans) with two pumps.

The idea was to cool the vpu, cpu and chipset. Since each block is going to increase my flow resistance (and add heat to the water) what if I were to have one radiator and pump devoted to CPU and the other devoted to VPU and chipset. This would keep flow high on both systems AND would also, I'm thinking, effectively keep all the chips even cooler.

Anyways, here is the case:

Sounds good, but how about using a double height 80mm for your CPU, and putting hte other single 80mm rad on a top blowhole for your VGA/NB?

I have a single 80mm that's collecting dust in my room....it's nice for old school systems, but for the high heat units we have now...just doesn't cut it.
 
why waste noise and airflow with 80mm when you SHOULD go 120mm?
 
I don't have access to all my tools in this apartment in order to cut the bitch up. Having to wait 2-3 weeks to go to my parents house (3 hours away) just to cut it up is not fun :( Then I'm rushed to get it done that weekend or I'll be waiting on it again.

I could modify it for 120mm fans, I've modified enough cases now to fill my parents basement (literally).

Really all I wanted to know is:

1. What 80mm radiators are out there (for single fan, not dual) that aren't expensive (i.e. heater cores from cars)
2. Whether 2 pumps and 2 cores would be a good idea

I'm mostly concerned with cooling the vid, chipset and cpu and NOT adding heat in the parallel connections and also not losing flow. Basically, I'm trying to have the best of both worlds by covering all my hot spots w/ water cooling and keeping high flow.
 
maybe try a diff case with 120mm top/rear exhaust fan unless you've alrdy bought that one.
 
Well if it isn't laws_69 hoaehoaheoha.

Sup. Anyways, um the heatercore you want is a 1986 chevette heatercore. I know the autozone here stopped carrying it, in which case they have to order it, but that means you have to wait. That core is perfect for 1 120 mm fan.

If your case is big enough though, i'd get the 2 120 mm size heatercore, the 1981 pontiac bonneville heater core. Here's a pic of mine below.

Funny thing is it was cheaper then the chevette core, at 17.99 compared to the chevettes 19.99. 2 bucks saved, and you get a bigger block which should fit your case i would imagine. Anyways pm me on irc since you know where to find me. (#ck)
 
How is that Bonneville core working out for you? I'm running a setup with an aftermarket trans cooler, and its keeping my XP2500+ under 32C at all times (overclocked to 200X11.5).
The cooler looks something like this, but measures 7 by 14 inches and uses 3/8 tubing. I was just wondering if that cooler would work any better than mine, and if it did maybe I would buy it and mount my watercooling system inside my PC instead of keeping it in my own homemade enclosure

As for the thread topic, I think that suggestion of using the dual 80mm for the CPU and a seperate single one at the top for the other two things sounds like a pretty good idea, and would probably win you the best results, if you like the idea of having two pumps in the rig. I've seen reservoirs that fit into 5.25 inch bays that have 4 holes for hoses, so you could easily run two systems out of one of them
 
Thanks for the info. I am aware of the over-abundance of dual 120mm heater cores, single 120mm heater cores, and the other conflagrations. I'm holding out for a dual 80mm core and a single 120mm core ( I will cut up the front metal facia for a 120, but there isn't room in the backend for 120's). I'd rather not put a radiator/core in the top of the case (I would if I had to, but I'm hoping to have a nice clean design w/ as short of tubing as possible).

I went out and bought my tubing today because I'm so giddy. :)

Going to get a Danner3 Mag and start off on the CPU cooling. Once that is in, I'll put together the vid card/chipset cooling system.

Nobody knows of dual 80mm cores? I'm not interested at all in spending $50-$75 on a dual 80mm radiator.

** I am not changing the case, I've loved that case since I was the bjorn3d review 3 or 4 months ago **
 
80mm heatercores are going to be a ahrd find. Look at motorcycle oil coolers or such like that would be my only guess.

Reason is, car heaters put out lots of heat...and to put out that heat it needs lots of surface area, so usually they are somewhat large.

Now for a motorcycle, the oil cooler is right out in teh open, so the faster you move (which gets teh oil hot), the more air is going through the cooler...win/win situation...so you can use a smaller core in that instance.
 
** BUMP **

Again, I want to know what heatercore will work for dual 80mm. No problem finding the single 120mm fan in front.
 
If your willing to go with a dual 80 radiator look at the black ice micro II.

Turns out my idea for motorcycle oil coolers to be used as rads isnt going to work...they are too small (go figure).
 
Yeah, but that isn't [H]ard buying it from a computer company. I want a heater core that I can paint, make a shroud, etc. They are a lot cheaper than buying something pre-made w/ heads already on the In/Out.

I'm not trying to be a dick about it, I just will not buy a radiator/heater core from a computer company. I just want to keep this open and see if someone knows of a automotive heater core that is the same size as a Black Ice Micro II or whatever you said....dual 80mm.
 
I guess you can just buy a caprice core and cut it down to your specs. Maybe even make it single-pass while your at it.

If your going for ultimate DIY, that's about as nice as you'll get without starting from sheet copper itself.

Yeah they do. For about $40 over the price over buying it at the auto store.

I've also decided I'm going to build my own waterblock (a whitewater knock-off, if you will).
