Do I need to run my pump all the time?

post #1 of 15
Thread Starter 
Do I need to run my pump all the time to keep my loop from corroding or is it ok to turn my computer off every night?

you can shut down over night.. corrosion only occurs if using wrong/cheep coolant.

Buddy you can turn it on and off as much as you like without fear of any issues. thumb.gif

I've got my server on when we need it on, sometimes it's on for days downloading torrents or no being used for weeks and no problems.

No, you can leave the pump off after your computer has turned off. You only get galvanic corrosion when you mix copper with aluminum. You don't need to worry about anything if you don't have two dissimilar metals in your loop.

right, don't worry bout it.

Corrosion is greatly accelerated when the water is not moving.

This from MartinsLiquidLabs' "Galvanic Corrosion Explored"
Quote:
We have seen failures on blocks and we have seen failures on fittings. The one commonality I have seen in all the various forum examples is “stagnant” water. Just like my radiator example, where you normally see plating fail, is where water sits still. I believe this stagnant condition is what promotes the #3 electrolyte condition. The longer the water sits still near metals the more contaminated and electrolyte like it gets. We typically see plating failures between surfaces such as the GPU block and acrylic or delrin top. We also see it between CPU nozzle plates and the CPU block bases plated in nickel. In fittings we see the plating failures at the threads…again where the water is stagnant.

How much an effect sitting stagnant will make will vary greatly depending on whether or not you are using any sort of corrosion inhibitor. That said, anti-corrosion additives/coolants will never completely counter the effects of corrosion over time. Their purpose is to try to slow down the inevitable, and to that end they tend to do their job pretty well.

Thanks for the useful info! I have about 17 cups of premixed Mayhems X1 but I put a good amount of DI water in after that so the ratio is lower than what is recommended on the bottle.

I will not worry about turning it off. smile.gif

Wouldn't deionized water be a safer choice since it has little to no electrolytes?

There is little to no difference between Distilled water (DW) and Deionized (DI), aka Demineralized water as far as it's use in watercooling goes. Either is suitable for use in your loop. Distilled is a little better in that it also is free from biological impurities that don't get removed from Deionized, but as soon as you add some sort of a biological control (Nuke, silver kill coil, etc) it makes no difference either way. If you can easily get distilled (like in the US), then by all means use it, but if, like it is in much of the world (like the EU), distilled is hard to find &/or expensive but deionized is prevalent, then by all means use it instead. All sorts of purified water, and even so-called "non-conductive" coolants start to become conductive as soon as they are added to a loop.

Martin also touched on a bit of that in this round of testing ...

As has been mentioned, it's totally fine to turn it off in keeping with normal use of the computer. That being said, if you ever plan on keeping it off for an extended period, it's probably a good idea to turn it on for an hour once every week or two.
