Silent Build / First Attempt

post #1 of 10
Thread Starter 
Firstly thanks to everyone who contributes here, I've been silently lurking on and off for a few months now and am always impressed by the knowledge and willingness to help others.

My conundrum is a brand new AMD Phenom II X6 1100 (running stock atm) that now resides in a Silverstone TJ06 (front & rear 120mms, front 80mm, PSU top mounted), which sits in one of those prefab compressed sawdust office depot desks that has less than ideal airflow (I removed the back long ago). In turn the desk is in my study, which on an average day has an ambient temp of 27C/80F. The room was poorly designed in terms of airflow, and since it is an interior room on the first floor there isn't a whole lot I can do about it.

My goal is to build out a future proof (i.e. capacity for additional loops/blocks/etc) cooling system that is also as quiet as possible. Previously my system could be heard two rooms away before I upgraded my E8500 @3.81. This irritated my wife who works from home a good deal, so most days I would come home to find my PC turned off. The noise has dropped a bit recently, I replaced my 4870X2 with a dual fan 6870, removed the True 120 (using stock AMD HS), and turned off the 5.25 HDD bay 120mm fan. Unfortunately I think the biggest culprit now is my PCP&C 850 PSU. (any suggestions for a decent 1KW+ PSU that isn't as loud as a 747?) I'm still playing with the idea of positive/negative pressure. (tons of dust)

Anyways I am probably going into too much detail. I am considering building a custom cabinet/desk for my PC with externally mounted rad(s). I don't want to get into putting blocks on everything right now so I know I will need some decent airflow in the case still. I'd like to start with the CPU and build out, but I don't want to be buying new rads/res/pump every time I add either. I figure I can start rough get the basics down then start planning my desk/etc. (think I saw pics of some here) My thought is if I have a big enough rad(s) with some decently quiet 120mm fans at low speed it will be as good as or better than air with less noise. Or perhaps I'm clueless...

As for parts I don't have a preference yet, though I have quite a few ideas, but most of the builds I have seen thus far are all performance without much need or care for ambient noise levels.

I'm looking to start piecing together something soon as I'd like to OC this new chip, and get my VMs back online during the day. I'm open to any and all ideas right now. I'm considering maybe a new case as well, not sure this one is suited to the task/environment.

Anyways thanks for reading.

P.S. I have little concern for looks, more interested in function/performance.

Well if you are going to build your pc into the desk I would suggest an open air system you can make your own mobo tray from a sheet of plywood. And either cut holes in the sides of the dest to run your rads or run the rads in the front or back of the cabinet. There are some projects going on in the case mod section where people have buit custom desks with the pcs integratedin theme so you can look there for ideas.

As for psus look to corsair they make some quiet units and are reliable. There are many good fans out there for quiet cooling. My favorite are the gentel typhoon fans for rads they move a good amount of air for thier minimal noise. I can keep my pc in my room on 24/7 due to their low noise output.

I didn't think of checking for a case mod forums, thanks headed there now! I've seen mention of those fans before, definitely adding to my research list. Thanks!

Np. Always feel free to post more questions/concerns even concept pics/drawing, lots of people here will try and lend some constructive criticism if they can.

You going to be building it in this thread? Watching if so

Otherwise I love the idea, there are a few I have seen with the idea and builds are amazing.
If I wasn't so portable with my PC I would do a desk PC in a second.

For low flow (air flow) radiators look into the SR-1s... they are really amazing for low RPM and silent solutions.

I am still still trying to size this project, but unless there is a major road block I intend to see this through. I started pulling out all my wood working tools yesterday, I need to build myself a new workbench and my son needs a new train table so I've some opportunities to practice before I start.

I think I'll be starting with a basic loop, looking back at my post yesterday I've realized future proof is a probably not the best idea starting out. So I'm going to dig and get my hands wet on this.

Thanks nickbaldwin86 for the radiator suggestion. The specs on the SR-1 480 is definitely where I want to be!

I've also started a rough sketch of the case enclosure, planning airflow, etc. I am wondering, if I chain 2-3 480s together, will I need more pump? I assume each rad is considered resistance, but I've no real experience with fluid dynamics (yet). I guess i need to order one and see how well it dissipates heat at what fan levels and pick a noise level that works for me.

Which reminds me I need fans.. off to look read up on gentel typhoons.

You need to make a work log I really want to see the progression on your project it sounds super cool. For 3 480 ease I would look to a a dual mcp 655 setup. 2 480s is more than enough for CPU and 2 to 3 gpus were you gonna cool the mobo as well?

SSDs, low-RPM fans, Black Ice SR1 rad(s) (http://www.hwlabs.com/index.php?opti...&id=6&Itemid=3), and a capable PSU. I've never had more than a 750 PSU since I've never needed to run the rest of my house off of it so noise from a PSU fan has been super minimal.

2 480s for a CPU and 2-3 GPUs?

A 360 for that would be fine. You only need 1 480 my friend.

So I've been cruising the case mods forums and found some great inspiration, particularly here. I'm going to need to rethink a few ideas and start putting things down on paper soon, or firing up my old CAD station (old as in 486DX2). Though maybe I'll try google sketchup instead, less heavy lifting.

I think when I get down to actually building out the desk I will start a new thread in the other forum, it seems more appropriate. I'll try to keep this thread to my WC questions and ideas.

Speaking of WC, bought my first parts today!

Black Ice SR1 Low Air Flow Optimized - 480 Radiator
MPC655
(missed the EK sale on Tilatech for the nickle supreme HF)

Since I am not overly concerned with aesthetics, if do not think i will bother with 45/90 fittings unless I need to. It seems the 655 has 1/2 ID barbs, so I'll stick with that. I don't see a whole lot of difference between barb and compression fittings, still looking though.

So things still needed:
Reservoir (leaning towards the one from danger den)
Tubing (thinking Tygon)
Silver coil thingie
Anti-gunk stuff
CPU Block (EK Supreme HF Nickle)


More later.
