potential upcoming loop advice

post #1 of 12
Thread Starter 
Hey everyone,

I've been considering throwing a custom loop into my rig for awhile now, the only thing really stopping me was not wanting the potential hassle that can come along with it; i.e. algae, leaks, maintenance.

But I just can't stand having my OC limited by temps, nor do I like high temps (who does?). Up until now I've been getting by with a crappy little Corsair H50, and my temps leave plenty to be desired.

I'm wondering what advice you would all have for me as I'm at a bit of a crossroads.

I either want to get a custom loop going, or absolute top notch air cooling. I was curious about a TEC cooler but I read nothing but conflicting opinions on those.

If anyone would recommend a TEC cooler or Air cooler that would dramatically outshine the corsair h50, I'd be open to suggestions - though please post temps @ idle / load, and preferably with a decent overclock to get an idea of how well it handles the extra heat.

If however the group consensus is to go with a custom loop, I'd appreciate any input as to the best possible components. i.e. brand of radiator / reservoir / pump etc.

I'm only going to be cooling an i7-950 and the NB of the mobo, but I want it to be on the overkill side so I have plenty of room to play around with the processor OC.

I figured a BlackIce 360 rad would be about right, but let me know if you think I'll need something larger.

I'm also not opposed to water chillers in the loop but I don't really know enough about them (wouldn't that cause condensation?).

Enthusiast comments/advice welcome and appreciated biggrin.gif

What are you looking to cool down in your loop just the cpu or everything else? I would go with 2x 360 rads and cool down your cpu and video cards. I also have built a custom water chiller, but mine is just a modifed air conditioner with the evaporator in radiator fluid, water chillers for hydroponics would not cause condestation will occur when the temperature of the air equals the dew point temperature so try if you would buy a water chiller try to keep the temp setting on the water chiller close to the ambient temp

I agree with wootang here. Focus on thos gx cards and cpu. 2x360 rads. single loop.

start with a rasa kit with a 360 rad
add a set of ek water blocks for your mother board

then if you want to cool your graphics cards (they give off alot of heat)
ek blocks for the cards (about 125.00 each) 375 for 3
a 360 rad possibly a 480 rad swiftech makes both for 50-60.00 range
a 355 pump and a swiftech micro res
that way you have 2 seperate loops and you dont have to out all the cost up front

Yea I want to cool my graphic cards some day but for now the CPU is what's bottlenecking the graphic cards.

@Satogd,
Would the Rasa Kit give the best performance? I don't mind spending the extra $$ for lower temps. Black Ice just seemed to be a reputable brand, but if you think the rasa kit would be best I'll take your word for it.

For CPU and 3x SLI...you are going to need some serious rads, nothing less than two GOOD, thick 3x120's.

I think you are seriously underestimating the amount of heat watts being produced by that i7 950 and 3x SLI 580's. If you are considering CPU now, GPU's later, do the Rasa kit for CPU only, and build a second custom loop for the GPUs later.

Or, better yet, start with a great pump, CPU block and 3x120 rad, add your GPU's later with more rad(s). If you KNOW for sure you are going full loop, might as well go this route now, save the headaches later.

@rubix_1011,

Thanks for the reply, I didn't mean to misconvey my plans. I definitely wouldn't add all 3 of those GPUs and the cpu on 1 360 rad. I'm planning on having 2 loops;

Loop 1- 1x 360 rad going to the Processor, then NB, then SB

Future loop 2 - 1x 360 (or possibly 480) rad for the 3 GPUs.

I apologize in advance, as I'm sure this has been answered many times in other posts, but are there any threads dedicated to the current "best of the best", showing their impact on temperatures?

I'm not opposed to the Rasa kit if it's performance is highly recommended, but otherwise I'd want to piece the loop together knowing each component was top notch (cpu block, pump, and rad in particular).

No point in having two loops, it's actually better for temperatures to use a single larger loop.

Here is what I would get:

MCP35X
EK Supreme HF Full Nickel
EK FC-580 GTX Nickel Acetal x3
EK Triple Parallel Bridge
EK GeForce Link x3
Bitspower 1/2" ID 3/4" OD Compression fittings - 2 per component - but only two needed for the entire three GPU setup - the EK Bridge connects them for you
GentleTyphoon fans (your choice of speed).
Primochill 1/2" ID 3/4" OD tubing in your choice of color - 10 feet
Reservoir of your choice - just get whatever looks nice
PT-Nuke Biocide.

Either XSPC RX series radiators for fan speeds <1800 RPM, and the HW-Labs GTX Series radiators for fan speeds above 1800 RPM. With the lower speed fans you're going to want a total of around 9x120mm of radiator, how you split that up is your choice. With the high speed fans you're going to want about 5x120mm radiator.

@Charliehorse55,

Thanks so much for the detailed response, after a few new developments, I've decided to go extreme with it and go with phase change cooling for the CPU.

That still leaves the NB/SB on the mobo and the 3 GPUs. Would you change anything with that component list without a CPU being in the loop?

Thanks again man, +rep

Nope, just remove the EK Supreme HF CPU block and 2 compression fittings.

Have you seen the FrozenQ Reservoirs? They may be the thing to add that extra special touch to this build.
