100% new to water cooling - Page 2

post #11 of 29
Do you want me to explain every part of a loop for you?

I'd be happy to.

Thanks guys.. I am still a tad bit confused as to how the water is cooled. Do we know how cold the water actually is? I feel like a cpu at 50C will heat water quite a bit, and that a radiator with 2 fans wont exactly cool the water fast enough?

I guess I just don't understand how the temperature of the water is changed so rapidly through this simple loop... Is the water fast moving..?

dumb questions I know.. I am sure once I get my hands on it, it will make alot more sense.



Also, do I keep the radiator outside or inside of my case, and is there a simple water cooling loop like this H70 but for GPU's? I like the simplicity of this, and maybe when I learn a bit more I will get a real water cooling setup.

The "heat capacity" of water is very high, it takes a lot of energy to raise it by one degree, so it's better then air to use for cooling. Don't worry, the Corsair H50/70 are a proven design, they work well.

There are designs like that for certain GPU's, but they're quite bad. I would either ignore GPU or go full loop. For a few dollars more, you can get an XSPC RS240 kit, mount it at the top of your case, but for your needs, I'd just get the H50/H70 for simplicities sake.

Mount it at the back of your case where there should already be a white bladed fan, internally.

Water has a very high specific heat (the amount of energy it takes to increase it by 1 degree Celsius) because of this the water will remain at a stable temperature even with very high heat. The temp of the water is not changed rapidly... on the contrary it is changed very slowly that's why you see very stable low temps with high cpu temps and volts.

Works very much like your car's radiator works.

The heat from your chip is absorbed through the medal of the block into the water. The water in turn is being pushed through the system by the pump into the radiator. The radiator is being cooled by fans pushing air through the radiator. The water passes through the radiator back into the cpu block. The process repeats.

There's a little more to it than that, but that should give you an idea on what is happening.

To explain how the water is cooled, you have to go into the laws of thermodynamics (movement of heat).

Heat will always move from a place that is warmer to someplace cooler. In essence the temperatures want to normalize, so that the cooler and warmer objects reach the same temperature. Think of a cold drink sitting on a counter top. When you first put it there, it's cooler than the air surrounding it, but leave it there for a few hours and the drink will be at room temperature. This is because the drink absorbed the heat from the air.

The same applies to water cooling loops, but in an accelerated way. The greater the temperature difference between objects, the faster the heat moves. So your CPU running at 50*C will transfer heat to a 20*C water block fairly rapidly. The caveat here is that the water temperature will always be higher than the ambient air temperature, but still much lower than the CPU temp. This is because it is constantly being heated by the CPU and cooled by the air being forced through the radiator, so it will want to normalize somewhere between the 2 values. Think of taking that drink you left on the countertop and adding ice cubes to it.

Now we come to why the radiator works. Heat is transferred more efficiently, the more surface area it has. This is why radiators have fins. The heat will spread over every little bit of those fins which gives the fans more area to hit with the air, which as stated above, is cooler than the water. The other thing to keep in mind is that heat transfers better to forced air, than to still air. Hold your hand out, it feels fairly warm in the air. Now hold it in front of a fan. It feels much cooler. The air temperature didn't change, the speed did. Your hand feels cooler because the heat it transferred from it to the air faster than it would in still air.

Sorry for the overly long explanation, but I hope it answers your question as to why it works. And yes, the H70 will work just fine for your system.

LOL at this which is quite right but also way over the OP's head.

Gotta love OCN....

To the original poster, get the H70, follow installation instructions, and enjoy lowered temps on your CPU.

Thanks guys, some really helpful posts here. If only there was a local computer store that sold these components so I can get my hands on it faster!

Maybe so, but I did make an effort to explain in laymans terms.

I also didn't tell him to build a custom loop when he had no such intention in mind.
