water chillers worth it?

[Teknokid]

im looking at a new water loop, to cool my cpu (q6600 OC as high as i can get it), motherboard and sli 9800gtx's when they come.
Im gonna use 2 triple rads and a dual, with a laing D5 pump.
What sort of cpu temp drops would i be able to get using a Water chiller such as this:

is it worth the money? or will standard water work just as well.
Also, can you use the loop with the chiller off?
Thanks

With 8 radiators and a chiller, you'll probably end up with room-temperature water. You'll cool the air going through the rads until it equalizes at a constant value

 

[urbsnspices]

You would get high points for coolness factor, but Im with Arcygenical.

BTW, I assume you already have the 3 rads? If not, why not just get a BIG single rad. Im a big fan of BIG rads and low fan speeds.

190w? That's not bad compared to a radiator but for the price that's pretty lackluster.
Or am i missing something?

 

[Teknokid]

i was thinking of this, would it work, pump--rads(removes heat)--chiller(lowers to below ambient)--b--locks-res--pump
what do you think?

 

[Drudenhaus]

For that price you may as well go with phase...

 

[Teknokid]

yes, but phase is cpu only.
Im going to want the max out my system, over water i will get what 200mhz xtra cpu speed, with water i can go a lot furhter with my gfx cards too

You can get a multi-evap phase unit, but I'd go for phase chilled water with that kind of budget.

It doesn't work like that. The water temperature will stabilize throughout the system. As Marci would say:

Order of components in a loop makes no difference. ...there is no "blah handles blah cos it goes to it after blah". Again... the order of components in a loop DOES NOT affect performance. It takes 261 watts of heatload to raise watertemps by 1 degree. Order in the loop is irrelevant.

You're missing the fundamentals of watercooling. http://www.overclockers.com/articles1088/

That said, I tend to agree with filthysanchez.

 

[Erasmus354]

To be more exact than Marci's 261Watts number out of a hat....

It takes about 81 Watts of heatload per Litre/min of flowrate to raise the water temperature by 1C. So slower flowing systems are hit harder by long loops (ironic being that longer loops are lower flowing...).


About the question at hand...no I don't think water chilling is worth it. You migh as well go for a multi-head phase setup.

 

[Arcygenical]

Exactly. That 190w of chilling power will only drop your water temperature by a degree or two if there's any heat-load in the loop... Not to mention the specs are all weird on that page. 100w of power input leads to 190w of cooling power? What parallel universe was THIS chiller designed in? Energy in will always exceed work-out.

And really, what's any of this going to do for you? Your temps, even with the nicest cascading phase units, barely go under -10c with a high-clocked quad core cpu... Not enough to get any incredible gains, unless heat is your limiting factor (IE: You have a kickass board/RAM/CPU.).

 

[BioVader]

I'll sell you a bucket of ice to run your loop through..

Water chillers are great if you aren't paying for the electrical bill. They do work mucho better than water cooling. Should have no problem hitting 0 degree C assuming you are using alcohol.
