water cooling question

[RJ]

If I were to get a water cooling system (aquastealth)for example,do u leave the thing running all the time or is it switched to come on with the PC ?

well i guess you don't have your comp on 24/7, you can rig it turn off after you turn off your computer or leave it running 24/7. My only thought is that you want the water to circulate a little bit after you turn your comp off, so if you made something like a time delay switch, would be perfect. Just whatever you want to do, the main thing is that you want to have it on when the computer is running of course!

My box has two relays. One turns the pump on with the system, the other switches the external pelt PSU voltage to the pelts if I am running them (I have two Danger Den blocks, one with pelts). I also have and suggest a bypass switch so you can run the pump without turning on the rest of the system.

The main potential problem with this is the pelt only comes on with the PC, therefore there is no time to chill the cpu. if your running way overclocked this could mean you can't boot (at least the first time).
I use a similar idea on my rig but I power up my 15V-25A power supply first which gets the pelt going and also switches a relay that turns on the power supply to the PC and turns on the pump. I can then leave it a few seconds to 'chill' before I boot the PC, works great.
It also has the added advantage thet a failure of the pelt power supply will kill the power to the PC thereby avoiding a meltdown.

The Vapochil systems incorporate what you have described Badger. Heres a quote from a review I read recently, "Running your CPU at high speeds and thus generating a lot of heat in your CPU before the cooling process has started may cause severe instability in the start up phrase - and maybe the system will lock up. To avoid this, VapoChill have provide a Chill Control Printed Circuit Board (optional), which holds the system in reset mode, which will prevent the CPU-core to generate heat until a desired cold plate temperature is reached."
I have not yet used a pelt (still trying to find a suitable ps) but did you experience this problem Badger?
