2 pumps???

[Red Harbinger]

hey guys i was wondering if im going to need 2 pumps i am new to water cooling. i plan on running a single 480 rad and a 360 rad, and the whole setup will consist of cooling my cpu, 3 graphics cards and using 2 250ml reservoirs (if that matters) and the pump i plan on using is the Swiftech MCP655-B 12v Water Pump (is that a good pump? like i said first time water cooling)

 

Also a side note, how power does water cooling draw?

I don't know much about water cooling, but i'd think that one stronger pump would be better than two. Having multiple points of failure in a system is never good.

If you have two reservoirs you should have two pumps, however you should also be fine just using one good reservoir and pump combo.

a second pump would add redundancy, so it would decrease the amount of points of failure

i recommend a single D5 pump

Is that really the better solution. Hum... When I think of it that way your probably right, but for your money i don't think it is necessary when computers today shutdown when they are in real danger.

 

Do you agree?

No need for two. What will happen is that the marginally stronger pump will push the water from its mechanism, through the tubing, filling the res too high and pushing too much water into the other pump.

D5? is that a better pump then the swiftech i was going to get.

seems like now im going with just a signle pump just wanted to make sure that it could handle alll of it so thanks for the responses but which is the best pump to support my entire setup???

Centrifugal pumps don't add much resistance if they fail, in fact having to pumps means the loop still works if one pump fails. It's not a point of failure, it's a backup.

No; really, a reservoir is just a really large bit of tubing with air at the top, when it comes down to it.

 That depends if you want your computer to still function with one pump. If your pump fails and you have no backup you have to wait a day or two for your pump to arrive, during which your PC won't work.

A Laing pump is a good choice. A DDC may overheat with the amount of resistance in your loop so a D5 is your only viable option if you want a Laing pump.

 

You then have the Choice of the Laing D5, D5 Vario or D5 Strong, a D5 strong is much more powerful than a D5 but requires a 24V power input to "be more powerful".

 

A D5 Vario if probably your best option unless you want to play around with converting the 12V rail on your PSU to 24V and use a D5 Strong.

Nope. You can have 2 res with one pump.

thanks man thats exactly what i wanted to hear im going to get the d5 vario like you suggested considering as i dont know how to convert the 12v rail to a 24v

Koolance sell converters.

[Red Harbinger]

Koolance sell converters.

do you think its worth it to get the converter or will i get same performance out of the vario 

[Ghost]

You will get a much higher flow rate with the strong version at 24V but your temps probably won't decrease significantly. Expect a very small decrease if anything.
