mcp35x2 - I dunno what got into me, but I certainly know what left my wallet tongue.gif - I imagine it was the redundancy feature, coz with only the cpu and a single gpu under water, with a few 90degree fittings, this pump is way overqualified. Maybe I wasn't seeing so many, and I compensated. Between your build and PCModderMike's use of beautifully topped D5 type pumps, I just didn't see a reason to try it, and look at the amount of money spent on this mcp duallie. I'll take some newer pix and start a log, so I can at least give you all another place to surf to and "critique" and offer advice and generally have a good time :-)
Didn't you get in on Dwood's cable clamp thingies? Since you have opened up your wallet you really need to get that build log going. The fun to me is watching the build as it's going on, not after it's finished.

Would love to have another 35x, now that I have one I really like the pwm function. Maybe not as pretty as dressed out D5's, but for pure utility and price I don't think you can beat them. I really like the amount of control I can get with it and the AQ5 Pro. When I think about all the money I sank into those two D5's on the other rig, with the BP dress kits & tops it's unreal.

Be sure to use resistors on your leds, since they have near instant response time, relative to the relatively long duration pulse of a 15khz source and would fry on anything but ne zero pulse width.

Yeah I have no idea what the 15kHz thing is all about or why they chose that freq. Only thing that makes sense to me is something that was designed in at the beginning for another purpose that never made it to fruition.My understanding (which could be wrong) is that even fans "like" a higher frequency.
All the led's I have are the type that come with resistors in line. I have never bought any single led's that I can recall.


Happy Thanksgiving, everyone, and happy birthday to me!

I decided to make a plate to fit over the back of the motherboard tray. I cut out a piece of 1/8" white acrylic sheet about 14" x10 1/2". Drilled holes to match the screws holding the rails that the motherboard tray slides on. Then drilled 4 more holes that match an SSD.
The screws that hold the tray rails in are #6-32, so I just used some longer ones in their place and then nuts to secure the acrylic.
The SSD screws need to be M3, and some spacers used under the drive so the power connector has room to plug in.

First a dry fit....


Satisfied that it's going to work, I peel off the protective backing from the acrylic and put 'er in place.
Now that area is usable if I decide to mount anything else.
I thought about cutting it to match the holes, but with it sitting on top of the rubber U channel it actually gives a little more room behind for screw heads, or possiblly wire, etc.

Thank you, pkkawakitty!
Someone let you borrow their STH10?? Cool!

My repair part for the flow meter arrived from Aquacomputer. So now I have two functioning flow meters. Had to raise the pump mount up a notch.


Recently I bought some 20 & 22 mm shrink from modDIY. Here is what it looks like after some heat:

It's pretty heavy industrial grade stuff, but the shrink ratio appears to be pretty good! Should work out OK for larger cables or wire splits, etc.
I bought some white as well. About time to redo those USB 3.0 cables with the white Techflex sleeve a la cpachris method. smile.gif

----
I finally abandoned my new SATA power harness. Evidently I get a brain freeze at the mention of SATA. The bulk of the wiring was just more than I wanted, and I had one hell of a time with the pins and connectors. Guess I'll go back to the punch down type. mad.gif
What people don't know is that when I first started sleeving, or attempting sleeving, I had an awful time. I destroyed the main connectors on my first psu (Seasonic as well) trying to get the pins out. That made me determined to, on this build, attempt to hand fab as much of the wiring as possible.
Although I've had some good success stories, the SATA power continues to elude me. I do have working cables, just not like I originally envisioned them. It's been a money and time pit.
I plan to go back and just remake the cables using the punch downs and call it quits unless/until I get better. I have thought about buying the connectors with the pig tails and just soldering them in, and I may go that route at some point.
Of course I have plenty of cables here from two different psu's so I could cut those off, I guess. Hmmmm. I just need to plan better next time.

Acrylic is truely wonderful stuff . . . thumb.gifthumb.gif

Practice makes for perfection or insanity, thumbsupsmiley.pngwheee.gif

It's which one comes first that governs the final result.



Trusting in my illusion of sanity,

Will the motherboard tray still slide out? Or do you have to remove to SSD and/or acrylic sheet first?

No, it will still slide out. I'm using the screw holes that the runners for the tray are mounted with. That was pretty much the point, that I could utilize the area without interfering with the tray. Working out pretty good. I did have to run to the hardware store and pick up some m4 x 12 screws so I could shim the SSD out from the acrylic far enough to slip the power connector in.
I placed a piece of 3/16" acrylic and two longitudinal strips of rubber plumbing gasket for the shims.
