Taking the Plunge: Converting my ATCS 840 to Water Cooled - Page 3

You guys may be 100% correct and I'll have to loop in a rad after the CPU...but that's the beauty of going simple w/decent bits and adding on...I get to play and experiment (and spread my budget across multiple pay periods). My initial goal from day one was to make the case as quiet as I could, reduce the fan footprint as much as I could, and maintain what I had previously w/combination of air-cooling and H50 cooling. We'll find out soon enough. That and the 460's run very, very cool to begin with in comparison w/the nVidia 5-series and the 470/480 parts.

You have to understand with 11 fans going it was LOUD at full power...

Leak tests tonight and temps test over the weekend if all goes well.

Running the leak test now. I have a small seep in the lower-most 90 degree swivel (Koolance) compression fitting (intake to the pump)...but only after I power down the pump. I't was a tad loose so I tightened it but still getting an occasional seep and not sure I can tighten it up anymore. So...after running this thing overnight (does not appear to be any additional seeps) I'll drain it, replace the washer, try it again. If that fails I'll put a straight compression fitting on and test again. If that fails...maybe a little plumbers-helper tape or in the extreme...replace the front end of the pump (If I stripped the threads).

Since this is my first shot at this I have a few observations:

1) The pump is so strong that other than the vibration coming off the pump, the loudest sound is the water pulsing up into the reservoir.

2) Noisiest thing is the pump...this is a HF system pump. I think the noise is primarily vibration-based. I suspect once I install the foam pads and bolt it down the vibration will be dissipated a tad.

3) I'm curious at how fast (in rpm) I should run the three fans. I know that's dependent on the heat coming off the bits...anyone have an "average" rpm?

Fixed the seep and threw everything together to run both leak and performance testing. Wiring will take a day or so once all is set. It's not sexy...but it sure is efficient.

The GPU picked up the best performance gains. I used to hit 50-60C w/my top 460 and now it doesn't go above 38...amazing gains there. I'll need to look into OC on that. I just put an air-cooled 460 in the box and while playing TF2 my water-blocked 460 never went above 32C while the air-cooled hit 56C. And...the case fans are only running at 1000RPM...about half what they can go at. Going from 15 fans to four also really cut the noise pollution.

So...for this setup one RAD is just fine. After I add another vid card and perhaps some mobo parts I'll add another RAD...for now it's tweaking, wiring, adding some drain and filler tubes.

Pics later but I added my second GTX 460, a 120Rad (between CPU and GPU's), and while pulling on a PCIE cable shorted out my 1200W BFG PSU. I bought a new OCZ 1250W and will begin cable sleeving in a week. It's a money pit...but that's OK. I ran both LinX and Furmark at the same time w/max temps on the i7 (3.66) at 60C and GPU's at 39C. Idle temps are 21C on the GPU's and 29C on the CPU.

Running my fans at 1100rpm and the nosiest thing in the bunch remains the pump. Getting Indigo Extreme in a few days and replacing some 90 degree compression fittings with 45 degree (I have a hodge-pod of fittings...EK, Koolance, Enzo, Danger Den...trying a bunch to see what I like the best).

Cool! Can't wait for the new pics biggrin.gif

Bad pics...just wanted to throw something up...dual Koolance waterblocks....very pretty but you can't see the covers at all.

I just threw the new PSU in w/total disregard for cable management. I temporarily tied the cathodes in as well. I just bought the MDPC sleeving kit and assorted other bits to completely sleeve the machine and that will start in a week or so.

Me too. Just when I think I'm satisfied after one mod, something else comes along and out comes the credit card.
