Thinking Of Getting This WC Setup, Help Plz :)

[Nick2k3]

I'm thinking of getting the following components for a watercooling setup:

CPU Block: Danger Den Maze3 478 1/2'' Chrome Fittings

GPU Block: Danger Den Radeon 9000/9700 1/2''

Radiator: 2x Black Ice Extreme

Pump: Eheim 1250

Reservoir: Tube reservoir, not sure on the fittings yet.

Tubing: Supersoft Silicon 13mm ID Tubing Per 300mm (Metric Foot)

(I'm assuming 13mm is the right size for 1/2" connectors, or do I need the 10mm size one)

My main concern is, will this all work together?

I've read you shouldn't mix metals in a water cooling system and because the waterblocks have chrome fittings, the blackice extreme has a copper core and I'm not 100% certain yet but I think the reservoir has brass fittings... will this cause a corrosion problem or can it be solved with some water wetter or something?

The idea for my setup is like this:

http://www.da014a0002.pwp.blueyonder.co.uk/wateridea.jpg

It would go from pump/reservoir to radiator 1, then into the CPU waterblock. From the CPU into radiator 2, then down onto the GPU waterblock, then from there back into the reservoir. I thought this system would be better because it means that at all times when the water enters the waterblocks it has been through a radiator to cool it as much as possible :drinky:.

Will this setup work? And will the pump be strong enough to send water through this amount of radiators and waterblocks?

Also... are the waterblock fittings compatible with each other and if not what can I use to stop corrosion?

Thanks :)

Also, just noticed this:

Hose connection (suction side) ¨17mm (3/4")

Hose connection (pressure side) ¨13mm (1/2")

The suction side of the eheim pump is 3/4" so, the res has plastic fittings (just found out) and also 3/4" so I should be able to connect the res straight to the eheim pump but the problem is... at one point I will need to go from a 1/2" size to 3/4" size when the water comes in from the GPU waterblock and into the reservoir so will this damage my performance or cause any problems? Thanks :)

hiya

mixing metals is generally bad but all the metals you've mentioned are pretty non reactive so you shouldn't have a problem... if there was any aluminium in there then you'd have trouble

next... why 2 radiators? i think you'd be able to get away with one unless you going for tecs

i changed all the fittings in my system for 1/2" brass ones (including the ones on my eheim a lot of people do that and its no trouble... either that of get a cup of boiling water and just strech the 1/2" tube across the larger connectors, its no big deal

If you really do want serious rad power, you might get better results from a single large rad (like the ThermoChill HE120.2 or even the HE120.3) than from two smaller ones - the pressure drop should be lower with just one rad.

Also, I wouldn't worry too much about the inline temperatures at any given point in the loop. There is actually very little temperature difference around a w/c loop (typically of the order of 1 degC) so the precise order of components shouldn't make that big a difference - it's much more important to keep the flow resistance as low as possible, IMHO.

The reason I was thinking to do it this way is if I took the cooling straight from the CPU to the GPU block I figured I would be dumping all the heat from the CPU and putting it straight into the GPU. This would limit my OC on the GPU because of the extra heat coming in off the CPU? Maybe I'm thinking wrong lol :drinky:.

yeah like greg says the temperature at any point in a WC system will be basically the same so i'd stick to the one rad

I like the dual rad idea, or get a dual-120mm radiator like the BIX2 or the HE120.2. It will probably be cheaper than two seperate rads, easier to mount, and give more performance.

Why go with a dual rad? More cooling power = quieter system. You can get away with using low powerfans. But if you use just one BIX, you may have to use higher power fans to get the same performance.

Plus, if your hacking a case, might as well go all out if yuo can. If yuo ever add a tec later, you will want this.

There's a Maze4 out now you know. It should work better. Actually, there is a new block out called the WhiteWater, check out Dtekcustoms.com or um... cooltechnica.com. They will have the LWRR blocks in soon, and they are supposed to really work extremely well. I hope to test one soon myself.

Dont worry about mixing metals, because you will be adding 10% anti-freeze to your water. This prevents metal corrosion, algae growth, pump failure, and deposits. Mix 90% distilled water with 10% antifreeze.

I would do my waterflow as below. However, as the guys said, the water temperature from point to point in the system will only be marginally higher than other points!

Resevoir -> Pump -> Cpu -> Gpu -> Radiators -> Resevoir.

A newbie might think that the GPU will run hotter than it should like this. Nope. The water coming from the CPU should only be like 1/2 degree higher at most. It WONT make a difference :)

If the resevoir has a 3/4" intake fitting, it wont cause any problems to reduce that to 1/2". Thats fine.
