Obsidian 800D project, need your advise.

post #1 of 11
Thread Starter 
Hi
I'm planning to mount my first watercooled case.
First of all, the components:
Mobo: Big Bang Marshall B3 (available 2nd or 3rd week of April, info from MSI)
CPU: I7 2600K
Memory: Corsair Vengeance
Video: 2 HD 6950 CX
SSD OCZ Vertex + HDD
PSU: Enermax Modu+900W
Can't get the Kingwin Led Mach1 here

Watercooling parts:
Phobya G-Changer 360 with 3 Gentle Typhoon 1850 on top (inside the case)
TFC XChanger 240 with 2 Thermalright TY 140 in front
Aquacomputer CPU Cuplex Kryos XT and AquagrATIx GPU
Pump: Swiftech MCP655, reservoir Phobya 150
Tygon tubing, Rheobus Zalman ZMMFC3
Liquid: PC Pure Primochill electric blue or Feser UV Blue

I know it would be better to use a couple of pumps to separate CPU cooling from GPU cooling but I want a single loop, don't want an Hydra of Lerna in the case
Front panel : here
I will get rid of the separation panel above the PSU (and strengthen the case), and the hotswap bay. I will drill a 120mm hole behind it, so I will be able to put a couple of 140mm fans to cool the TFC XChanger 240.
I will put a grill on the front bay such as this one.
The fans: Intake---> 2 in front, and the rear one, or bottom if the pump don't block it. Outake ---> 3 gentle typhoon on top.
I want to maintain an equal or slightly negative pressure inside the case, and have the best noise/performance ratio possible.

Since I am a beginner, I would apreciate your comments, suggestions, concerning this project and also the watercooling hardware I have selected.
Thanks a lot

Yes, one loop is fine.

Go with a high performance radiator, like the RX360, GTX 360, TFC TA360 as its good enough for a cpu and 2x gpu.

If you need more rad, you can install a 240mm rad @ the bottom (click my project where I put an RX240 at the bottom of the 800D) or modify the top for a 480mm rad. These paths are not as complicated as your idea to put in the 240 on the front.

GT fans are the best (if you can swallow their fairly high price and can find some ). Also, avoid dyes, as they stain and most irritating, they clog up your blocks. Get distilled water and silver, add color tube and leds if you need color in your setup.

Consider EK, HK, & Koolance for cpu and gpu blocks too.

good luck.

Exactly what wermad said.

Stay away from dyes...colored tubing (feser/primochill) or even the uv reactive tubing would be your best bet (unless you want to use clear and add a bunch of led's/ccfl's into your case)

If not a silver kill coil, you can use silver plated compression fittings...performance-pcs (or frozencpu...I forget which...senility) carries them for $7.99 a pop...best of both worlds with them. (unless you're taking the barb route)

GT AP 14's/15's are great choices for fans...with RX rads the 14's would be the ideal choice.

Thanks a lot Wermad and Mongoloid, the tubbing infos are really helpfull.
Your Obsidian looks great Wermad, could you tell me the gain in temperature in a push/pull mode for the 360 compared to a single line of fans ?
Don't you get dust in your bottom rad through your xtra fan ?

load it goes up ~5c when I shutoff the pull fans. That was the last phase of my build, Im working on a new one that will incorporate two 480mm rads

Cut the top and put in a 480!! Btw, just use water and uv tubing.

Just had to add: CM Excalibur fans sure push a ton of air...1700-1900rpm, and they go up to 2100)

Plus the fan noise is bearable with no detectable rattle.

These fans are in my final list, I was just worrying about the noise . I like the holes on the frame of the Excalibur.
