Single D5 pump enough for my planned WC loop???

[felang]

I have a single XSPC D5 vario pump that came with my XSPC raystorm kit.

I´m planning on expanding my loop to accomodate my cpu, 2 video cards, 2 radiators (360mm + 240mm). Should I get a second pump or is this D5 powerful enough at max speed?

Thanks.

One pump should be sufficient.

One pump should be sufficient.

Thanks, also forgot to ask what case you guys would recommend for a 360mm + 240mm setup, so far I´ve been looking at the Corsair 800D and NZXT Switch 810, any other options I should be looking at?

 

[aigomorla]

use low restriction eq, and 1 d5 should be sufficient.

That means no high performance injector cpu block for you.

Either case should work. I'll refrain from suggesting other cases as options that I would suggest would easily double the price of the Corsair 800D.

Raystorm has low restriction compared to other blocks. Whether its a good thing or not depends as there are high restriction CPU blocks that perform better at cooling the CPU.

Thanks, I would love to find a smaller case for a sli gtx 680 + 2600K loop but so far it seems like I´ll have to go full tower. Especially since I currently only have a slim 240mm rad so would probably need to go for a normal thickness 360mm. The Switch 810 seems to be quite a bit cheaper than the 800D, so I´ll probably with the NZXT.

The 800D wouldn't easily accept the 120x2 radiator without modification, so keep that in mind. I've had to hack the heck out of my 800D just for my loop!

Switch 810 it is then, thanks. Although the phantom 820 seems quite nice too, more expensive though

Enough? Yes. Would I recommend it? No. I will never not dual pumps. Pump parity is worth it 100% of the time.

What´s the worst that can happen if my pump fails? Isn´t thermal protection built into everything nowadays? Won´t the system just shut down if video cards and/or CPU get to hot?

It´s just a gaming system, I´m not doing any mission critical calculations for NASA LOL

Now you're making me want to add another pump! Although, I kind of want to do it just to raise my LPM without raising the noise.

I'd rather not risk damage from overheating when an extra pump is so cheap. I leave my system on pretty much 24/7, so if a pump were to fail in the middle of the night and my CPU / GPU didn't shut off for some reason, I could easily fry it.

And in the event a pump does go out, you don't have any downtime. You can order a new one and continue with your daily activities until it arrives. And last time I checked, Amazon doesn't sell watercooling gear so no $3.99 next day delivery. =(

Pumps are cheap? I have to ask... what sort of pumps are you going with? D5 variants seem to be the quietest compared to their performance, but they're also about $80+ each. My system is pretty much inaudible, but I bet my performance is suffering because of it consisting of only one pump (lower flow rate ).

Plug the monitoring cable of the pump directly into the CPU fan header. Then set the machine to shutdown if there is no fan rotation. This is a common feature, its often something you need to do to get the motherboard to even boot without a HSF and it defends you from the potential pump failure.

I agree with the sentiments that the pump could fail and produce a lot of downtime, it does take 5 days for me to get water cooling parts and some water loops have taken a very long time to go together due to that delay. But strictly speaking you don't need 2 pumps, I ran on 1 for 5 years without issues, they are remarkably reliable considering what they are doing. The previous loop to that one did die on a pump failure, but it ran on idle for days without the pump, its only on load it crashed due to the heat.

That seems like a great idea, will definitely try to get it set up that way in my Asrock mobo´s Bios.

One day, young grasshopper, you will master the dual pump.

$80 is a lot cheaper than a new CPU or GPU. I saw something awhile back that 1.5GPM is your ideal flow rate. Anything about like 2GPM gave no improvements in deltas.

That is an option, but not always a viable one. My pumps don't have monitor cables though. Just 2 pin Molex, however, they are a bit old. >_> The last time I had a pump go out in a single pump loop, even at idle, my system would climb to quite a high temp very fast. I could not run for more than say 5 or 6 minutes before it would shut off.

Oh, I think it may definitely be rather soon, sensei! I just need to decide whether to swap to a new reservoir that supports dual pumps or just toss a pump somewhere in my loop. The prior is simpler and easier, but the latter is definitely cheaper. Although, if you combine the price of the prior with the latter, I can go with a dual-pump top and have three pumps! :twisted:

Only problem is that I have no idea what my flow rate currently is! I'm guessing that it's not high because the PWM for my motherboard is set to SILENT and the RPM is being reported at ~1500. I've seen that companies like Koolance have in-line devices to measure flow rate (and monitors to hook said meters up to), which might be nice to have. Do you use anything in particular?

This....this guy knows his stuff :thumbsup:

 

[aigomorla]

.75-1gpm is ideal...

1.5 is where u start seeing things flatten out.

Dual pumps gives u more security incase u do have a pump failure.
Also it allows u to keep your system running while your pump is either getting an RMA, or your buying a new pump.

I will never run a system without redundancy because ive had pump fail on me before.
Ive also ran into every type of worst case scenarios, that i learned what to do to stay very far away from them again.

U wont get a major performance boost from a second pump unless ur system is very restrictive.

But statistically speaking... if u have a 1% of a pump failure.. the odds of 2 pump failing at the same time is 1% of 1% = 0.01% or your PSU just died and took your entire system with it.

oh boy... need CDC STAT!!!
we got an outbreak of watercoolingidus loose.

u can also use martin's flow calculator to do the math and get a rough ballpark.
Go on skinneelabs and look for it.

Haha! To be fair, the reason why I am considering beefing things up is because I like to also keep things quiet. My pump is on a fairly low setting (PWM-controlled), and I'm a little worried that it's not really pushing enough. Since I don't have a flow meter, I kind of have to eyeball it... whatever that means! Anyway... I barely see any turbulence from the water entering my reservoir, so that doesn't seem too good.
