Critique on loop please?

post #1 of 14
Thread Starter 
Hi,

Just putting some plans together for my first loop. Space is a little restrictive (case is a Cooltek W2), but I think I have what looks on paper a reasonable setup.


Click for larger

WC Spec:
Radiators - 2 * Hardware Labs Nemesis 240 GTX X-Flow
CPU Block - EK Evo
GPU Block - EK (when it's released for my card)
Pump/Res - EK XRES D5 100
Tubing - 16/10mm Flexible

Hardware it's cooling:
Xeon v3 1275, basically an i7 4770 (yeah, not overclocked but will be updated to something quicker next year)
GTX 1080 (Palit Super Jetstream).

Regarding the radiator choice, firstly I'm restricted to 30mm clearance of the graphics card - also these seem 'well optimised' for low rpm fans, I'm aiming to keep sub 1000rpm at all times if I can. The reason I'm thinking X-flow is that they seem to work better in terms of layout keeping the tubs as short as possible and keeping the internals fairly open. Also, the non xflow variants of these rads have much more restriction (as they're 2 pass). In my head, this may mean having to increase the pump speed to compensate?


Some questions:

Is PWM worth it for the pump? The pump noise is the only thing I'm 'worried' about per se, so being able to control it via PWM based on temperatures is appealing - but I'd lose the ability to control the 4 radiator fans independently via PWM as my motherboard only has 1 PWM header for CPU, so I'd have to control those from the system fan header which is only voltage regulation.

I was planning on having the drain on the return from radiator 2 before it enters the res/pump by means of a quick disconnect fitting or valve of some kind. I'm actually planning on running the return tube on the case floor, so it would be almost at the bottom of the loop, with the exception of radiator 2. Is there any issues with doing this?

Is there any problem having both the inlet and outlet of the pump with a 90 degree fitting going straight up/down? I've seen pictures of setups similar, but just want to check...


I know plans will likely chance once I start to get parts and test fit etc, I won't be picking anything up till I get back from honeymoon at the end of August - so have plenty of tine to plan! smile.gif


Thanks

No need for a PWM pump really.

That location is pretty good. Use a valve.

90s out or into the pump are just as bad as anywhere else, so no it isn't bad.

Loop is fine.

X-flow rads are fine, there is only a marginal difference in cooling vs. U rads, and you have enough rad space it you will probably reach diminishing returns anyway.

PWM pumps are all personal preference. I don't like to throttle my pump, I would rather set it and forget it, but some people like PWM. PWM pumps can have issues when bleeding the loop because they don't run at 100% when no PWM signal is connected.

I don't see any issues with your drain plan.

The more elbows you have the more restriction you have, but it has been tested that it takes about 30 elbows before it adversely affects flow. Some people still believe a 90 on the outlet is bad, but realistically I can almost guarantee you it won't be an issue.

Be careful with 4 fans on one Mobo header. Depending on how much juice the fans pull, it might be too much for one header to handle.

Yeah I'm looking into either a pwm splitter (powered) or maybe the Acquero 5 LT

As long as the fans are under 1A you should be fine. The amp ratings on Corsair fans already take start up boost into account as well, so you're good there. But beware of Gentle Typhoon fans, because they have some pretty ridiculous start up boost. When in doubt just check out geggeg's site (Thermalbench) and see if the rating on the fan sticker takes start up boost into account or not.

I personally wouldn't put more than 3 fans on a header with a splitter. If you need more than that then use a fan hub. However I also use all my headers so I can adjust fans differently in groups. Like at load temps I like to ramp up my high FPI rad fans more than my low FPI because they will give better performance.

I'm more than likely going to be using an Aquaero 5 or 6 for the fans I think now.
