View Full Version : heat pipes and water cooled pcs...I

are they worth it?
i see some motherboards now come with heatpipes.
and that cpu, video cards and memory can all be water cooled now...
using water means no fans so less noise, but is it better?
is it really water inside or some other liquid... doesnt it evaporate over time? some of it looks like its neon... i guess it'll be cool if your case has a cut out window to see the light show.
This (http://www.xoxide.com/water-cooling.html) might interest you, although it kind of reads like a high school science project.

I'm not really convinced of their value as a computer cooling system. It isn't hard to quiet a computer with air cooling for less work and less risk than liquid cooling. I have a quad CPU computer next to me and it's close enough to silent for me that I have to put my head within a foot of the system to hear the fans. The loudest part is actually the hard drives, and those are very quiet. I say that because liquid cooling can't do anything for hard drive noise. And you still often need a fan to cool the radiator, so water cooling is mostly about relocating the fans.
The best step is to dump the stock cooling system on a graphics card and replace it with an aftermarket one. I've seen decent ones go for $20-$30 USD, price varies by region. The stock graphics fan is usually the worst in a computer anyway.
If you truly needed dead silent, you'd get the funky heat-pipe type Zalman case, which the entire case is tightly sealed and the case itself is a heat sink. It's rare to need that type of case, which is fine because it's expensive.
Water cooling is still considered exotic and it's not really worth pursuing unless you really want a high-end system that's super quiet, but motherboards and coolers with heatpipes are very common now. In fact I wouldn't trust a motherboards that isn't passively cooled. The idea behind the heatpipes is that it can shed above average heat generated by overclocking, but the design usually expects the builder of the system to put an appropriate amount of active cooling in the case in the form of intake and exhaust case fans. The heatpipes aren't much help if there is nothing to carry the heat away afterall.

It depends how far you're going to push the machine. For most intents and purposes, I'll agree that liquid cooling is pretty much about geek cool. But for bleeding-edge SOTA builds, it makes sense. I've heard anecdotal accounts of people overclocking C2D processors up to 4-8Ghz with liquid cooling. But that's very much the exception rather than the rule.
