Finally managed to watercool my X1900XT, decided to run a second independent loop for the gfx, its running a Laing DDC+ pump with plexi top and res, Swiftech MCW60 block with AS5, 120mm rad, and oversized 3/8th barbs.
Was a tight fit and took quite a bit of thinking to figure out how I could fit it all in my already rammed case. Managed to get it up and running with little issues though.
Load temps have dropped dramatically!! With the stock cooler I was seeing 80C on load when looping a 3d benchmark. With this watercooling setup the load temps run no more than 38C!! I was expecting an improvement but not an improvement that actually halves the previous temps! I’m pretty chuffed tbh.







Now to tidy up inside the case and overclock the heck out of the gfx :D with cat 6.9 the card is stable at 741mhz stock voltage which I think is real good on stock cooling, hopefully now with these improved temps I can up the gpu voltage and up the frequency even more.
 
Good Job mate,I'm in the process of adding a second graphics card to my loop so have some thinking to do also,not quite sure how i'll go about it yet.

Your setup looks great,is that a Lian Li v2000 case?

Using an original CM stacker myself,currently have a 120.2 rad at the bottom of the case,it fits perfectly over the pre installed vent,I reckon i'll extend the vent and ditch the 120.2 for a 120.3,should hopefully be enough to cool an extra gpu.

na, its a v1000 plus, a v2000 would offer up loads more space inside i should imagine, damn big case externally though!
think jokester runs a 120.3 in his single loop to cool 2 gfx cards and a cpu. I prefer the idea of multiple loops for cpu and gfx, but it makes your setup a little more complex and slightly more expensive.

I prefer the idea of a dual loop also tbh.Instead of disrupting my current loop,I'm thinking of adding a 120.1 loop just for the second gpu,all I need is the rad as I've already got parts such as a Laing D5,aquatube res etc sitting around doing nowt from a previous setup.

I've even got a rad (Thermochill P.A 160) but it's just so damn big! can't see how I'd fit it in along side the existing H.E 120.2,so I'm thinking a 120.1 rad mounted externally with a radbox would do the job.

All this thinking is giving me an 'eadache man! :eek:

Yeah, I've just got the one loop, not sure if it makes that much difference if you've only got one pump and split the flow.

Looks like you've made a neat job of it.

Good job Heskey temps look fantastic just ordered the swiftech gpu block on Friday so it,s nice to see some pics of it installed and temps..
 
Had a crack at overclocking my newly watercooled card today, I'm well impressed!! Had a feeling the low temps would help my overclock but I didn’t expect it to help my stock voltage overclock so much!! as I said before the card was stable at around 740mhz with no overvolting, simply thanks to this watercooling setup I'm 10mhz shy of 800mhz that’s a 50mhz boost!!! This is on stock vgpu to. a while back I managed to net around 45mhz extra with a slight overvolt (1.4v) with stock cooling before but temps were always an issue and they went uncomfortably high at times, and I’m sure they limited me. Shouldn’t be a problem with this water setup now though, 850mhz here we come :)

Simply can not believe how much this stock cooler holds this card back!

Have you got ELSTRING inside your pipes their bud?
nice one if u have.....
 
Decided it was worth spending that extra 7 bux on the sapphire card over the connect3d after all :) these BJ11 1.1ns ddr3 ram chips have come good! managed to get a game stable 1890mhz out of the ram on this card with just the stock 2volts! I'm not sure if running higher will help but I would think it would be safe to go as high as 2.2-2.4v, not sure as I haven’t tried overvolted the ram yet. but atm the extra clock on the ram gives a real big boost in performance. pretty sure the ram is runnning much cooler now they have there own ram sinks and no longer share the hot gpu heatsink

It's two watercooled PSUs and that tubing is the steel re-inforced stuff.

oky, forgive me for asking what might be a stupid question but....
how come you got re-inforced pipes on some areas and not others?

simply because of the bend radius I would assume. all tubes have a minimum bend radius, if exceeded the tube will pinch.
