You planning on massively overclocking your cpu?

maybe a little, I know its more then likelay over kills but see packages for 150$ for a complete kit. The motherboard I am looking at, hell can't buy it for another week has water connections for the chipset even built in. So thinking screw the fan worth 50$ toss 100$ onto that and get a liquid cooling kit. I love to tinker with thigns and try new things out so maybe this could be fun.

ITs using the new chipset thats just being released by nvidia suporting ddr3 memory and whatever else. Basiclay newer version of board I was going to get anyway.

i water cool my cpu. not for overclocking but to reduce noise...

i was thinking about doing it for noise reduction myself...

Steel ive seen a few types of coolers for the water cooling. some have a fan cooled radiator, while others just have a radiator without a fan, what one did you go with? and why?

this may be a project i might do this summer.

ok steel what kit did you use, any recomended brands hints tips and such. And you hit the nail on head on why I want watter cooling. I may do minor over lcok but if I can make a quilter system great.

i got a thermaltake bigwater se. works great, everythig in one package. it was a but tricky to get the pump situated just right, but once i got it no problems.

BH, if you get one that does not take a fan it will need to be a large radiator. mine has a rheostat to control the fan speed, and i am able to have it set low enough i don't hear the fan...and the radiator/fan combo hangs on the back of my pc.

is that the one that takes up 2 drive bays ???? I looked at it and looks nice

ive been looking at the thermaltake stuff as well. specialy considering thats what my case is anyhow. Thanks for the info. will have to realy start considering once it gets a bit warmer.

Reviews seam to be good as well.

PC cooling

Hi everyone! Long time no see.

My super thoughtful husband, Grifter, forwarded this thread to me.
This is really "cool". I wish I new how to build a computer.
But I do have some knowledge about cooling.

I have so many questions!!! I hope some of you are as into it as me?
First of all, how much heat output are we talking about typically(how much cooling is needed)? Or are we just overcooling to be sure not to undo it?

Steel - I'm a little confused about the thermaltake bigwater. I think you said it was a water cool device, so I was intrigued. I see that they used the term water when describing their pump and the "waterblock" (whatever that is - looks like a device to allow the liquid to pass the hot object?)... However, they then refer to a coolant that is refillable. Very curious here. Are there two liquids? Is it a water glycol mix?

Softball - The Freezer 64 Pro looks like the heat is pulled from the liquid and drawn out with the air, which matches what we are saying about liquid cooling (not air cooled). So where in the pc does the liquid go through? I saw the refrigerant piping stopped at the top of the heat exchanger. Does that connect directly to a waterblock?

oh, and just a note about the Scythe that Vegeta mentioned. I saw a review that said it was a huge part, very large. otherwise had a good review.

Okay, have to go. I hope to learn more. thanks.

one liquid container... it is fillable, ha a removable cap. there is some liquid loss over time. i have had to refill mine once in about a year or more...

they have a special liquid to prevent rust, not full glycol.

the system has the reserviour (refillable), the pump, the water block (copper with a "maze" to maximize contact with the coolant as it flows through) which attaches to the CPU, and the radiator/fan assembly. you can add other water blocks for things like chipsets on the board and video ram and gpu's.

i use it instead of a fan to reduce noice. it is quiter than a heat pipe/fan combo - but does cost more. most folks that use these do so because they will overclock their cpu.

heat output of a cpu varies depending upon the model of cpu. some of these nowadays can consume 130 watts at full load.

The one that softball posted doesn't use liquid ... they call it a "heat pipe" but I'm pretty sure it's just air. That is what I have in my machine and it's just a slightly more sofisticated version of a heat exchanger where you blow air over metal fins to disipate the heat from the CPU. They use copper tubes to transmit the heat from the cpu to the metal fins. Not sure the thoery on that one (even though I should).

no, there is actually liquid in a heat pipe - and a wick. it is not liqiud/water cooling though. different concept. heat pipes do work well though (when designed, constructed and installed properly), better than just a heat sink.

oh, ok. I guess it's just not user accessible/serviceable.

Posted: 21 Mar 2008, 18:19
by Hammer
very correct. if you crack that pipe the whole thing is ruined...

and, it is not filled with liquid, only enough to evaporate and cool and flow through the wick.

heat exchangers

so if that pipe is liquid filled how does it cool the pc? Does it connect to a part?

Well the theory is that as the liquid is warmed up it circulates round the pipes away from the processor due to convection (same reason water in the bottom of a pan rises to the top when it's boiling) up to the cooling fins on the heatsink, the fins absorb the heat from the pipes which then get cooled by the surrounding air which is being blown through the fins by the fan. The now cool liquid returns down to the processor to collect more heat and the cycle continues.
