How many people run there PUMP 24/7??

[Sproket]

I have had a fish tank for a long time and running a pump 24/7 is what the pump is designed to do.
BUT for a computer running your pump 24/7 you create more RISK. I have a Eheim 1048 now it does not get that hot but if the computer is Not on the little heat from the pump will build up in the case b/c of no air movement, so when you start your system your starting out Warmer than usual, including water in Rad.
PLUS if running pump 24/7 there is more chance of having a water leak, burning pump up, ruining hardware, etc.

NOW having pump on a Relay you just keep hitting the pump with voltage every time you turn it off or on. Pump really not designed for that, could cause it to get noisy over time or burn up.

These are all the Negitives I can think of. What do you Do or Suggest?

Thanks

i run both pump (via aqua 1300) and computer 24/7

yeah me 2

Same here. Computer and pump running 24x7. No problems yet.

With an aquarium, it isn't much of an issue, because the flow restriction is just not there.

With a rig, the load is well out of a pump's optimal flow range and so, you can expect your pump to draw more power, and heat up more.

A lot of people run their pumps 24/7, and don't report any problems.

If you want, the simplest way to shut off your pump, is to wire in a relay, so that the pump shuts off with your PC. It's a really simple mod

You also have the option of adding a bypass button, in case you're working on your cooling system, and you want to turn on the pump without turning on the PC.


edit: you can also put in an outlet, on the backside of your PSU, so that you don't have to cut into the pump's wiring. Like this


edit2: you can also use a solid state relay, instead of a mechanical one, for more reliability.

Danger Den sells a PCI relay card that allows you to run the pump without the machine being on, or have the pump turn on when the machine is turned on. I ordered one of these when I ordered my watercooling kit last week.

There are a couple of pump relay kits out there that do the same thing, and cost about the same. I think Swiftech also sells one, but it's nots based on a PCI card.

Im putting my system together right now and I have a relay kit from D-Tek. I just thinking whether to use it or not.
I will have to cut my wore for pump.
No big deal just thinking twice.
I have read other threads here about the subject also.
Thanks Again.

Cant wait to see the results of WhiteWater over Air Cooling

Run pump 24/7 but switched computer off at night in the beginning in case it leaks.

I run my Eheim 24/7

[Cova]

I run my ViaAqua 1300 24/7

It's wrapped in foam to make it quiet, and it gets very warm in there when the PC is off - I stuck a thermistor under the foam for a while, and upon turning on the PC and taking a reading as fast as I could before it could cool off, the pump was around 62C

Then again, it only takes about a minute if that for my water-temp to return to normal idle temps once that rad-fan starts turning. If I was OC'd to the point where it wouldn't boot without first getting the water to idle, I would just build a small circuit like in a Vapochill that would run the PSU (and all the fans) for about a minute while holding reset, then let the system boot.

FWIW...

I just pointed out in another forum that the Rio 1100 would be ideal to run in series:
Max head: 6 feet
price: $19.99
price @ qty6: $17.99
Max flow: 382 gph
(from: www.greystonecreations.com btw you might still get the ProCooling discount)

Putting 6 in series would give a total head in the order of 36 feet (10.97 meters, or 15.6 psi).

The problems are:
1-the pump housing may need reinforcement, as the amount of pressure may cause leaks.

2-this pump may or may not last long, in-line. Rios are very popular, but the bigger ones can get fairly warm. They are designed to be run submerged.

I run my Gen-X pump 24/7, and have been for about five-six months in a highly resistant system, so it stays pretty hot. I haven't had any problems whatsoever. I am planning, though, on replacing it in a year and a half ... I'd rather spend $100 on an unnecessary replacement than lose over a thousand dollars on burnt equipment, and it will leave me with an emergency spare.

I think they heat up less with more restiction. at least thats what I've been told. Next time I take apart my rig I'll have to test that.

Anyway relays are stupid. Just leave the pump on, its made to run years without fail, so why bother switching it on and off?

I run my MaxiJet 1000 24/7 inline for almost 8 months now, no problems, works great.

[p0b0y]

Ive run my eheim 24/7 for over a year now without any issues.

I run a Laguna Stat3 24/7.

I used to unplug it at night but it makes a horrible buzzing racket when I plug it back in. After about a month of that I decided to just let it run one night to see if the noise would annoy me. Ever since I suspended the pump in the res with its own tubing it doesn't make very much noise at all. So it runs all the time.

Since about 50% of my cooling comes from evaportation there isn't a build up of heat with my PC off. Infact it drops from a stable 31.4°C (water tempature) when my PC is on to 24.8°C everyday while I am at work. It won't go below 24.5°C with the pump running with a room tempature of 21°C.

I've been running my VIA 1300 24/7 (usually) for nearly 2 yrs with no problems (Glue Mod)

[golovko]

i run my danner mag drive 3 24/7 (with the inlet-seal mod), no problems yet ~1.5 years of operation...ive heard that most of these pumps are designed to be run 24/7 and not be turned off and on (by a relay for example), i dont know if thats true or not tho

[mfpmax]

My MaxiJet 1200 is on as long as the computer is on.

Hi BigBen2K,

Just wondering if you could provide some evidence that backs up the statement the pump is running out of its optimal range, as everything that I've been able to find suggests that something like an Eheim 1048 pump is actually quite likely to be running in it's"optimal" range in a computer setup.

Thanks.
