Is it possible to use 3 radiators for a single cpu water cooling?

[etalns]

I have an athlon xp 1900, and I Was talking to a person and he told me that if I have the following

Pump --> Radiator 1 --> Radiator 2 --> CPU --> Radiator 3, repeat infinite.

That I will be able to oc my cpu like mad, the one question I have is, is it really worth it to cool avideo card? I've heard that ocing a video card doesnt really create a visible difference and your giving yourself a huge hassle for something that relaly isnt worth it.

What's your thoughts on this?

Everyone has their own reasons for OC'ing. Would I overclock a GF3? I doubt it. Would I overclock a GF2 MX? Heck yes! The reason being is that with a GF2, I may get 19-20 FPS, and with overclocking, I will get 25-27 FPS. That is a visable difference, and worth it. As for a GF3, I would get 100-110 FPS, Oc'ed I would get 130-145. That difference is not visable at all to the Eye. ( everything over 60 FPS is wasted, as most people can not see anything over 35-40 FPS, but I would prefer to have about 60 FPS )

As for a CPU, more is ALWAYS better, IMHO

A for the setup you have listed, why the 3 radiators? You are not going to get any better cooling, as you can only cool the water to ambient tempeature ( room temp ) Adding more tubing and radiators will just slow down the water, and ot help much at all. Just get one large ( AKA Good ) radiator, and be sure you get all the air out of it. If you are going to overclock your vid card, you can add an extra radiator ( read: loop ) to cool that.

<edit>
What is overclock like mad? You WILL hit a limit based on the reistance inherent in the CPU. The only way to get past that limit is with more voltage, or lower temps.

Example: Most 600-750 AMD durons will not post over about 933-950 MHZ at 1.85v at ambient ( I have 4 durons all got to that range ) if you up the voltage to 2.0+ you will be able to get farther, but getting above 1.85v on most boards requires soldering (read: mod ) the board. If you lower the temps to below ambient ( even below freezing ) you will be able to go farther at 1.85v because you lower the resistance in the CPU. The only way to get below ambient is with some kind of heat pump such as a Pelter or refrigeration. The problem you run into then is the condensation ( ice ) that can form. Ice = water = bad for electricity = dead CPU or Mobo You will have to find a happy medium. As of yet I have yet to try water cooling ( not enough $$ yet ) but I have done tons of research on it, including helping build a friends non-pelter system.

If he has a good enough pump the slowdown won't matter. And if the one radiator doesn't cool down the water to ambient, the water to the CPU will get warmer and warmer. And having a faster pump is better for cooling anyway, provided you have enough cooling (which he will if he has 3 radiators).

I would not watercool my video card. There's no point to it.

Use a bucket filled with water as your reservoir, and put ice in it. That should do the trick.

Here's a dumb question-- I am new to water cooling but considering it. If one were to put two GOOD radiators in the loop, is it possible that you could eliminate fans? My goal is complete silence, and I have lots of room to work with. If this person were to put two good radiators in, with decent exposure to ambient air, a good pump, and a large enough resevoir, can we eliminate fans altogether?

that would be sweet.

Anyone have good pointers to water cooling web sites/purchase places for the novice who wants to set up a high-quality system?
