Risk of pump failure

[azhari]

I'm finally going water cooling. The noise is driving me more nuts than I usually am ;)

Anyways, I was thinking about the chances of pump failure. I'm getting the Maze 2 from DangerDen with an Eheim 1250 pump, and my system is in my sig. I'll be using a small closed reservoir with a Super Cube radiator. I'd like to know two things:

1) How reliable are the Eheim 1250's? I've heard a lot of good things about them here and that's why I decided to buy one. But should I be worried about it dying anytime soon?

2) If the pump does die, would a case fan aimed at the Maze copper block be sufficient to make sure the cpu doesn't fry?

I have been running Eheim pumps for a long time. One of them has been in service for a couple of years now and still works fine and I have never had one fail yet. A good pump like a Eheim is a lot more reliable then a fan. People should be more worried about there HSF quiting then pump failure. It takes some time to get over the fear and paranoia of such a trick cooling system, I know it took me a while but in time you will feel more comfortable with it. If it makes you feel better you can use software to shut down your system at a preset temp.

It'd take quite a few minutes from pump failure to critical temps in your system. Much longer than if you cpu fan failed.

Thanks for the reassurances. I feel a little better now.

Ken, what software are you referring to? Since I leave my comp on all day while i'm gone i would feel much better with that software protection. I would appreciate a link if you have it handy.

its motherboard monitor is what i use very nice and simple imo.
http://www.aoafiles.com/ is the link to it

even with direct die cooling a pump failure will not kill a processor straight away. and ehiems have a lifetime warentey so i doubt any will break

I have had my eheim 1250 in service for about 9 yrs ...7 of them it ran 24/7 in my 110 gallon aquarium till I broke up with my girlfriend and she poured bleach into my tank :mad: The past 2 years it has been in my computer and I even unplugged it to simulate a failure and it took almost 5 minutes to go from 30C to 60C at which point MBM shut down the system. Only thing I can think of to warn you about is don't do anything stupid like I did and overtighten a brass fitting into the outlet :P use the proper plastic fittings...seems I cracked something and could'nt get rid of the small leak...no problem it works well as a submersive pump too.

GREAT :) I feel much better now. I just can't wait to get the stuff.

I'm a newbie to the Eheim 1250 but I've been using Eheim cannister filters on my 2 aquariums for several years. All the equipment that Eheim makes is quality stuff. That's why it costs more than a lot of other products. The 1250 I installed in the P3S system is dead silent.

Just get a program that turns of your computer if the temperature gets ridiculously high... I can't think of one of the top of my head (maybe motherboard monitor?), but they are out there.

Just a quick note - I just installed a (standard?) kit from Swiftech - don't know a THING about it, yet, and I'm getting LOTS of noise from my EHEIM. Did I get a bad one? Not bleed it enough? It's easily as loud (uneven, quiet vibration/clicking) as the 4 old case fans and proc HSFan I had running - which was the reason I switched to water cooling in the first place...so far, I'm not impressed with the noise, though the temp is great. It almost sounds like the noise is coming from the intake nozzle. Could there be a bad seat there?

It's an Athlon 1800...Not OC'd until I figure out the problem.

Any thoughts? It did take about 6 tries before the pump would even start...the instructions from Swiftech sucked big time. The materials were good, and the mounting is all external

My eheim was making an uneven sound semi loud sound when it was sucking in air from the res. when I first to setting it up. It also made a lound vibrating sound when it was set on a aluminum table I was able to make it almost silent by getting rid of the air bubbles and setting it on a piece of carpet.

Look and see if there are air bubbles in the lines and set the pump on a mat or something rubber mounts would be good.

Im not watercooling yet, but when I do I'm using two Pumps...

My career was in Aviation and in aviation everything has a backup.....Call me paranoid, call me Ishmael, I dont care Im using two pumps and if many of you pester me about it maybe I'll use three :)
