6x140mm Radiator

[ddbtkd456]

 

So my question happens to be this, if I put 2 of these in a custom desk...would 1 loop 1 pump work or would I need dual loops & pumps?

[Excon]

1 MCP-655 will do fine with 2 of those

Alright what this:

 

Radiators:

2x840 mm

2x420 mm

 

Water-blocks:

2xGPU

1xCPU

Having that much radiator is just pointless.

Any reason as to why?

Because even with 2 420s you can run your fans at like 500 rpm all the time. It's just a waste of money.

Any reason as to why?

 

Also, super long loops may cause higher temperatures.

In the for whatever it's worth department, I have a XSPC RX 360 in a loop with an external MO RA3 - 420 Pro (size of 3-420 rads). I have a 3930k @4.6Ghz and a EVGA GTX780 Classified OC to 1306 core and 1697 mem, both under water. I had a single D5 XSPC bay res and flow and temps were good. I decided to opt for a Twin D5 bay res where the pumps run in series. The flow rate increase helped a few degrees.

 

A single loop is generally simpler and with that much rad space temps would be VERY low either way.  What are the cpu and gpus?

One the pump is a D5 you will only need one pump but you can run two for redundancy and slightly better temperatures.

Listen to ExconHD. He knows what he's talking about. A single or dual loop is up to you. Most people do dual loops for aesthetics. Since you're clearly going for killer temps and low noise with that many rads, personally I'd go with 2 or 3 480 UT60's in a single loop with a single MCP-655.

up to a certain point the reduction in temperatures just by adding fans/radiators

gets to be a non-return on investment. for e-peen/ballin' looks-wise it'd be epic,

but for actual usage, you'll find that one would prolly suffice and the other would

be just for kicks. but if you have the free-cash to do so, would be pretty neat, don't

expect 10° above ambient device temperatures, just won't happen.

@airdeano Would 4 560 be better?

@ddbtkd456

better at what? temperatures? not really. once you get past 6x140 you really

are not getting much more temperature drop (considering fan speed). device

temperature will be no lower than 65° on a massive overclock on CPU and

45° on GPU with voltage overclocking. there is a point of diminishing returns

past a certain point.

If I had a single exhaust (6x140mm) radiator and the 2 (4x140mm) as intakes on both sides for serious positive pressure or what do you think this is just kinda open planning here. The desk is 71.5" long by 30" wide. With a glass piece on top.

[airdeano]

@ddbtkd456,

what fan and what speed?

[ddbtkd456]

@ddbtkd456,

@airdeano

I was thinking either the 140mm xcpc fans from frozen CPU or rosewill hyper sorry I don't have the time at the moment to look them up will post back when I can link. I think rosewill are 1200 but I could be wrong and the xcpc ones are 1350 but for silence I really don't want to run them above 500 run, at least that's what I think but an area that big I could run the xcpc ones at full speed as intakes and then exhausts at half speed.

@ddbtkd456,

 

well at 500rpm, you are almost passive (non-fan use). sure, 8x140 cooling is overkill,

but for your plans just fine.

Well thank you so much for answering all of my questions... It's going to be unique that is for sure. I will be using 45 degree boards within the inside to direct airflow as well.

[airdeano]

@ddbtkd456,

 

at 500rpm, there is no-flow to route.you'll have enough to get the air possibly

through the filter, then through the radiator and that'd be the feat. nuttin' after

the rad(s).

I think the intakes and exhausts will be at full speed....I will have a couple of fan controllers to quiet them if needed.

No just want my 71.5" by 30" computer case to be cool...in a normal rig it is kinda pointless.
