Watercooling risk, etc..?

post #1 of 31
Thread Starter 
I'm a complete noob when it comes to watercooling, I want to build myself a small cpu loop (rasa kit) as a base and I want to know the risks involved when doing a custom waterloop. Like, what are the chances of the pump failing, leakage, etc?

Well, assuming you use distilled, which you should, there shouldn't be any ions in the water, so, if it does leak, no parts can short, because the thing in water that can make electrical devices short is small particals, called, ions. This is why distilled water is great, because as far as I know it's de-inoised.

There are a few risks, things like during installation breaking certain components. If you do it well and take your time, and if all goes well on the equipment end, then you should be able to sleep well at night smile.gif

Depends on how carefully you check your loop. The risk is - it leaking, going all over your expensive equipment, and then needing to buy all new components smile.gif But that is just my own personal experience b/c of a leaking cpu block smile.gif

Pump failures, pretty uncommon and most the ones I have heard about you could see coming. (noise, heat, loop performance declines), to solve that most quality pumps provide a fan speed header 3pin connector which you can monitor pump rpm's with, many bios's allow for a setting that if that rpm = 0 the pc shuts down, otherwise third party software like CoreTemp may be used to shut down the pc if it gets beyond a user defined threshold.

Leaks, you want to use some teflon tape/plumbers tape on fittings to prevent gauling of the threads, different people feel different ways, but generally, 24hr testing using a psu with a jumper or dummy plug to run the loop before power is applied to the pc will reveal any poorly installed fittings/leaky blocks/rads (though a rad should be cleaned before use).

Those are the 2 big ones...

any water even distilled can become ionized. all it has to do is hit a particle of dust and boom, you're now conductive. I just shorted my video card which is underwater because one of my compression fittings leaked and I'm using distilled and a kill coil.

Well, you don't need teflon tape. Otherwise, good advice.

Leaking and pump failure aren't huge issues if you do everything right. As long as you keep a close eye on your rig for the first several hours, everything should end up fine.

I've watched an installiation guide by TimeToLiveCustoms (OC3D) and It seemed pretty easy to install a basic cpu loop, and since you guys said that pump failure/leakage isn't that commen (if done properly), I think I'm going to buy the rasa kit when I get the money

if you do it right:

1 - take your time
2 - Use the correct parts (thread sizes, o-rings, ect)
3 - bench test (only power up the pump and not the whole pc)

your risk of damage is almost NIL

throw it together, plug it in to see what happens and then your playing russian roulette

One last question.
I currently have a H70 in P/P with a pair of Scythe GT AP15's, I guess the 120mm rasa kit would be beaten by the H70, right? Which kit would outperform the h70?
post #10 of 31
hahah the rasa kit will kick the h70 to the curb and then some
you might use those fans on your rasa kit though
