[Build Log] - The Big Budget Boomer Box (aka, the "BBBB") - Page 311

Powered and up and running on its own power supplies now. The difference in temps....is amazing. I'll log some extensive data for component temps and water/air delta...at different fan speeds and flow rates and show some cool charts soon. It will take awhile to compile all that. But just looking at some basic stuff, I can see how much the improvement is for water vs air:

GPU -- My 2x 690's would hit 90+ degrees during stress testing on air. I'm sure they were being throttled...although I don't know the exact temperature that it kicks in at. I would always stop the stress test because I was scared about how high the temps would get. No more. On the EVGA Furry-Tessy Donut, my GPU cores are maxing out in the upper 30's and lower 40's, depending on other factors. That's an amazing difference! Should allow me some room to use a larger GPU boost clock.

CPU -- I've toyed with mild overclocks in the past. The highest I could go without getting scared about the temps when it was on air, was about 4.4 GHz. Cores would get up into the 80's at this point under a Prime95 load. Now...on water....a Prime95 load at 4.0 GHz is maxing the cores out in the mid to upper 40's! Clearly have some headroom to play. I haven't gone higher than 4.0 GHz yet on water, but that is next.

Water/Air Delta's -- I need to finish some power connections for some of the fans...but even with not all of them spinning...it looks like water/air deltas are going to be less than 2 degrees for a CPU only load....and less than 7 degrees for a CPU + GPU load (Prime95 and Furry-Tessy Donut at the same time). Will be curious to see how much the delta's improve once I have all fans running and replace the one pump that is not working.

Flow Rates -- Only 3 of 4 pumps working...but I'm getting about 1.0 to 1.2 gpm for the cpu subloop and gpu subloop combined. Through the use of the valve system, I can divide that flow up just about however I want to between the two subloops. Right now the radiator loop is getting about 1.3 gpm of flow. When there is a difference between flow rates between the subloops and the radiator loop, the crystal link connection between the reservoirs serves to transfer water from one reservoir to the other. I've watched the flow between the reservoirs reverse direction depending on what the flow rates were (based on opening/closing the valves).

Awesome! Fantastic temps.

So glad to see this build log being updated again, I thought all was lost frown.gif

Edit: Is that Lego Harry Potter I see in the background of that photo?

Its amazing how a watercooler system can lower the deltas and keep things under control even under load.
Love your build, all the attention to detail, the patience in fitting it all. I still think that using white-powdercoated copper piping would give it a much better look, but it is amazing as is.
Congratulations, cpachris all that care and love you put into this build finally paid off... And I bet that even with all the fans spinning, it's whisper-quiet.

Really want to see those charts XD

I think you can bring your combined delta's down a bit, but will be curious to see if more flow helps any as you are pretty much in the sweet spot.

Can't wait to see difference in temps on water vs air. Wish me luck.

Implying that there is no air. biggrin.gif

Yay!

Well done for getting her fired up, looking forward to sitting down with a mug of coffee and looking through all the stats!

Good eyes. My 9yo son's lego projects grew to dominate the living room shelves over a year or so. He has just about grown out of doing them, so perhaps I can put them somewhere. But yes...Harry Potter can be seen in the background. But there are also Star Wars, Lego City, and Indiana Jones sitting n various places. Lots and LOTS of star wars...because I think they are cool too. smile.gif

White powdercoated copper, huh? Sounds nice. I like the look of plain copper tubing a lot...but I'm not happy with any of the connectors I've seen people use to attach the tubing to the components and/or fittings. Perhaps someone will create a nice one someday.

And yes...it is more silent than I could have hoped for.......when the raid card fan is not spinning. It's the only component without a water block, and the little fan on the booger is loud. When I unplug it...everything is so pleasantly silent. Will need to figure out a way to waterblock that card at some point.

There were 16 rad fans still not spinning for the preliminary delta's....so I think it will improve when they are all running. And yes...I'll be curious to see how much flow impacts component temps.

Annnddd, I've finally caught up on this log of yours. It only took an entire sick day in bed!

So question: You've got XT and LT mounted 1 space apart on the front panel. I found it's necessary for the same exact reasons though since the LT is mounted behind a one-spacer front plate, it's just ever so slightly at a different depth from the XT on top. When I attempt to plumb, there's a short gap. A connection could be made though not without bending both PCBs. How'd you go about solving this riddle?

P.S. I love your build and you hou look into watercooling your radiators ... 50+ fans ... do you have a pond outside to do swampcooling? rolleyes.gif
