What methods are being used to make sure the pump isn't forgotten when the computer is turned on. I ask because I dont want my chip to fry when somebody uses my computer (Like my little brothers friends or something) in my abscence.

Are some (or all?) pumps on when they are plugged in? If they use a switch, is it a single state switch (like on any ATX case), or do they use a 2 step switch (like the old computers where the button would feel all loose when the computer was on because it was really down)?

If they use a single state switch, it would probably be pretty simple to wire the computer power button into the pump, right?

I just leave it plugged in...

I used to do the whole on/off thing but one time I forgot to plug it in and I have never left it unplugged since unless the computer itself is not going to be on for long periods of time (out of town, etc)


I eventually want to incorporate a "monitor center" into a box I am going to be build to hold all my cooling kit. Just some basic flip switched (off, high, low) monitors by LED's and stuff. A pump switch, and a master kill switch - etc. Been thinking about maybe using some kinda flow meter and possibly rigging it to set off an alarm if the flow drops to a certain point (is that even possible with flow meters? cheap ones)

That will pretty much be my solution.

[thegrouch187]

u can buy these flow regulator things that plug into the mobo that u hook up to ur tubing and it moves a little fan and if the fan stops it tells the computer to shut down i know innovatek sells them but i dont know how to hook them up but i know there out there.

the psu that I have has an ac output socket that I modded an old monitor cable for. so if the psu is getting power my pump does also. others solder the pumps power cord into the psu which is abit more direct. there are many articles on how to do this.

what you do really depends on how much you trust your skills and what kind of power your pump uses.
as for the power button that would only work if your power button was not a momentary switch and your pump runs on dc voltage. it would be possible to find a way around this but it would be beyond what I can think of right now

I hope that helped abit.

get a relay

[Stoanhart]

im not quite the electronics expert (i get the basics). What is a relay though. A quick explanation would be great

[Penguin4x4]

Relay - device that responds to a small current or voltage change by activating switches or other devices in an electric circuit.

Basically when you push your case power button, the relay turns on the pump while delaying the system from booting up, so that you can get some water flowing through the blocks before your system boots up.

[Stoanhart]

Cool. Sounds very useful. Allthough I really think the delay is trivial. People have run 3dMark without their pump on, and their temps only got to lke 62 after like 10 minutes. I forget who posted that, but I remember it. Anyway, when I turn my computer off, though, won't the pump shut down first then wait a few seconds before turning off my computer (I use the press the power button and computer shuts down method.) Again, this is probably trivial, since like 30 seconds with the pump off won't kill my CPU

this should answer all your questions:

hi

i'm going to use a relay but to get the mains power for pump i did this, and also got a cable for the monitor, so in effect i get 3 power pionts off one mains plug !!!

outside:


inside: notice white plug for pump connection!


i cut the back of case yesterday just got it in! and used old psu(120watts) for all the sockets....

[Stoanhart]

cool site. I've only glanced, but it looks to answer pretty much everything. thanks for the help

[Malpine Walis]

I know that this would be going about things the easy way but why not use a powerstrip or surge protector so that is simply not possible to turn on the computer without having the pump on?

[Inept]

That's the correct way, Malpine and it's what I do. It's free since I'm sure you've got a power bar already. It's easy since anybody can plug in a cord.

I have my computer and pump attached to the same power strip. The computer will not run unless the pump is on. Just that easy.

[HaywirE]

Why not just leave it on?

Cant you get a flowmeter or something?

You could always have some sort of switch on the front of your case, that when you turn on your cpu it turns on the pump as well... hmmmm..

Like jumps it..

[Stoanhart]

I think I probably will just leave it on. I never thought of doing that since I figured I'd be wearing out the pump. That website that tseongsun posted made a pretty good point. These pumps are designed to run 24/7. Turning them on and off once a day just damages them. I'll probably wire it so that if the power cord is in the back of the PSU, the pump will be on. That way, if I go to a LAN or something, I wont forget to turn on the pump.

Thanks for all the responses. they've been very helpful

[HaywirE]

Yeah... like someone said before.. just turn off your WHOLE surge protector, because if you just turn off your pump you may forget after that nice vacation.. just turn off the whole surge protector.. other then that just leave it on, That way you're computer will keep cool.

no dont worry about your pump burning out :O

hi all

i just bought my relay 12v from the house electrics shop, normal house hold gear...



its 2 pole so i can use the off position as a buzzer warning if relay dies in mid quake3 an alarm goes off due to the power still coming from the psu !!! as it flicks back to its off position.

and off course when the comper is turned off theres no power from the psu so the off position would be dead so the buzzer will be switched off.

also i bought the mount housing so when the relay needs changing i can pull out the old from the socket and stick in the new !!! easy life yeah.....

and all working from the compers main power on switch, ummm nice......and also i am waiting for an inline flow meter to come with my water cooling kit from innovatek.

thx.........

[Friend]

IMO the realy os the best idea...

Murphy was an optimist...if you leave your PC unchained around little kyds and parents they will fry it at the first opportunity and feel no guilt whatsoever...they will probably blame you!

It's a relay or a Pit Bull staked next to the PC if you wanna be sure.

Oh yes you aint kidding there !!!

just need a water kit to turn up now cos i'm ready for it, well had to do something well waiting?

this "IMO" word what deos that mean???

thx........

IMO = In My Opinion.
