How Effective is Water Cooling?

post #1 of 15
Thread Starter 
Just how effective is water cooling vs. air cooling? I've heard that unless you buy the more expensive systems, air cooling will usually beat water cooling. Is this true? If so, what is it about the more expensive systems that make it able to cool the PC better? If you do buy a more expensive water cooling system, about how much cooler can you expect your temps to be? To me, it seems like once the water (or coolant) is warmed up after passing through a block, it would take quite a while to cool down.

In air cooling, if your CPU starts to heat up real hot, the fans kick into a higher speed and bring down the temp immediately. Does water cooling have any sort of "over-drive" mode like that, or does it keep the CPU so cool that it should never need to kick into "over-drive"? Also, has anyone ever had a lot of trouble fitting their water cooling system in a Mid-tower ATX case?

As you can tell, I'm very very new to water cooling. Since I have an HP, I can't overclock my CPU, and I won't be upgrading to WC. However, in about 2 years I'll be building my own PC before I go off to college, and I'd like to start learning about water cooling. Thanks!

Depends on what setup you get. If you get a crappy Watercooling kit then yes air can beat it. If you get a good kit, or build your own air connot beat it. ( i suggest not going with kits ) .

Here's that might help u

Yes that's true, cheap water cooling is not as good as the best air cooling. I tried it myself with a cheap coolermaster $50 kit that only has an 80mm radiator...my scythe infinity did a better job cooling and quieter at the same time.

The reason why water cooling is so good is because of two main things:

1) water conducts about 25X the amount of heat as air.

2) Your radiator size is not limited by the space around your CPU

You still have to move that heat to a radiator and have enough surface area and fans to remove the heat, so it has the same process as an air cooled system except you have the ability to move it to a better place. Check out the FAQ links in this forum...lot of good stuff around.

You can get a pretty decent rig for $200 bux and up...I run 7-9C over whatever the room ambient is on a 3019mhz OC at 1.55 V-Core


..Water is a lot better at removing heat then air..That is what the rad in a WC loop does it removes the heat from the coolant...

Chalk another one up for peddling liquid cooling.

It is effective. Saved me having to down-clock during the Summer. Though you will have to buy quality components (US$ 200-300).

a good watercooling kit is just about the most practical cooling you can get

I like water more than phase because its just about impossible to mess up on.

with water I can run any voltage I want without having to worry about overheating

I don't think your getting paid enough for this i-rak. You have sold more watercooling parts than newegg and eBay combined! *i can't think of the name of the site with all the WC stuff....*

Do you get kickbacks in the form of overclock.net appliques?

You can get awesome temps with water cooling.

Its a lot of maintenance

Its silent

Once it's set up, you don't really have to maintain it at all.

Just make sure the res/t-line is topped every once in a while and change/flush your loop ~1-2 times a year.
