Wall mounted & passive cooled

Hi all

After a bit of water cooling advice, for my Folding@home cruncher.

Rig:
[email protected] (375*8)
Abit AW9D-Max
1gb Geil DDR2 667@750
36Gb WD Raptor
200Gb Barracuda 7200.7
Enermax Liberty
7300 SE (passive)
Silverstone TJ05
currently cooled with a xp-120 and three ambers (in-on-out) at 7v's (coretemp - 45c)

Looking at a silent solution and just got a good deal on a Zalman Res2.
Extra complication is I'm thinking about wall mounting the lot but the pump only has 1m of lift :eek:

So Firstly I'm in need of a better pump if I do mount it above my case - surgestions please.
And secondly how many Alphacool cora will I need If I go quad?
would be mounting these in a 'ladder' so boost the cooling potential of the Res2

I'll be writing up a log of this when it moves from the floor to the wall.

Swiftech kits seem good little kits for the money im considering getting one myself

I haven't seen any data on the heat capacity of the Cora. But with this unit at least you can add more if you need the extra capacity. A complete guess says 4 cora's on top of the resorator. 18wDDC with aftermarket top and barbs for 10mm should be plenty.

You are looking at c180w of heat with your current CPU I guess. c220w with an overclocked quad. That's a lot of passive cooling!!!!

Would I really need a 18w pump? or is that for the quad build.

The DDC-1 Ultra has a Max head of 6.1m - thats massive :eek:

and it's also arround 30dBA - which is to noisey

The 10w pro seam more like it - Head (4m) 24dBA
But even that seam a little over kill for my current E6400.

Res2 has a 3w internal pump (1m lift

) but your expected to have it at 'or slightly above' the case (aka base at GPU level)

I'll be looking at mounting the Res2 ~7-800mm above the case so I'd expect a pump capable of 2-3m lift addaquate (tell me if I'm wrong)
If and when I upgrade to a quad I'll resize the pump then or if the price differance is minimal I get a more powerful pump now.

Would multipul smaller pumps in series work - thinking about sound more that efficency
