WC is more powerfull than air by how much?

[MeltedDuron]

Watercooling is better than air we know that, but by how much more.

How do we base this on what, a basic set up. CPU only pump, rad, block, res, fans?????????????

Im kinda confused to how much more powerfull WC is over air cooling on a project im working on that will use water maybe as the cooling if it can be proven to be better than air cooling but it's not for a pc but along the lines of pc stuff.

Im finding it hard to put the question into words really.

Say thus

AC can do 100w @ 60c
WC can do 100w @ 40c

Thats a 20% increase in cooling is it not?

Someone please help, im being really thick

[SoulsCollective]

Far too many variables to even begin to make accurate predictions on a percentage basis. Give us more details and possibly we could help out some more.

[Zehnsucht]

The main reason why water cooling is better is because the increased surface area of which the heat can be exchanged. And it's very easy to increase the heat exchange area for WC compared to AC.

There are other factors of course as well. Such as air resistance in the fins (both for air and water) etc.

[Caoder]

usually to achieve the amount of cooling wc can reach.. air is usually MUCH louder.

[NaeKuh]

water will not get u better overclocks unless u were heat limited.

What is heat limited?

Well lets per say, if your chip can do 1.4vcore on air and pull 80C, then on water it could probably do it at 1.55vcore Thats ASSUMING ur chip can overclock higher @ 1.55Vcore.

However if you have a bad chip and its cap'd at a GHZ @ 1.475vcore, water will NOT help you overclock.

usually to achieve the amount of cooling wc can reach.. air is usually MUCH louder.

^ this is usually the advice i normally give.
And not a promised Overclock increase.

MeltedDuron,

Just a single data point but my system (see sig) went from 79-80 deg C at ful load at 4.1GHz to 65 deg C under water (also in sig). So a full 15 deg C improvement.

P.S. See my recent thread here: http://www.xtremesystems.org/forums/...d.php?t=232964

u really cant tell people there gonna get X benifit.

Souls said it best because were missing a ton of variables.

Also what was the sink in comparision, whats your water system now.
Your gonna net a better delta if you were on stock and now your on a MCR320. vs if you were on a TRUE and now your on a MCR120.

This is why its impossible to answer the question with the an exact answer the op is looking for.


You watercool more because its fun, the performance and lower sound noise is a bonus.
But an Air system will net about 80-90% of what a water system can do.

The main factor is are you gonna have fun when its watered?

Appreciate the difficulty of providing a real answer without more data from the OP. Did you read my thread? That provides the background to the comparison in my case. I did say it was just one data point

Im moving from air

Xigmatec 1284EE and 125cfm 120mm fan

Phenom2 965@1.47v 3.9ghz

idle 35c/ game load 51c / prime95 load 55c

to water

Enzotech Sapphire waterblock
Watercool MO-RA 2 Extreme Rad
XSPC dual bay res/pump

so I will definitely be getting some results between the 2 setups within the next week or so as Im waiting on the rad.

Water has a higher specific heat capacity than air. This means you can dump much more heat energy into water compared to air, before it's temperature will raise by 1 degree.

[Tackleberry]

depends also very much on what kind of rad you are having in your system

[Asylum1]

To many variables to list but mainly water will net you about 5c-7c lower temps over air.
You may get better or worst results depending on your setup.

I've always found people to get a bigger difference between air and water than that

No, studies shows the difference being this much:

Would you say wc'n has a plethora of benefits?

Three Amigos reference, FTW!

To the OP, what fans are you planning on using? And will that pump work well with that HUGE rad??

[lesstutrey]

Personally, i think this is in the wrong forum, since you're really asking about phase cooling, just using water to replace a condenser. Well.. you might be able to beef up a condenser with water, but cooling 1500w on water == never gonna happen with common place stuff, maybe the radiator from an IROC with some sort of iwaki bilge pump. But even with water you'd need a radiator for that to vent the heat displaced into the water, so i don't see how it would save you any space in the phase installation.

[MrBean]

AC can do 100w @ 60c
WC can do 100w @ 40c

In your hypothetical scenario, it's 33% more efficient.

(60-40)/60 = 33.3%

Enjoy.

[NaeKuh]

but cooling 1500w on water == never gonna happen with common place stuff,

done it with 2 feser 480's and a san ace core in between..

[Supergroover]

In the end it will still be air cooled. Only you will have a water loop in between.

The water must be cooled by air. Since you can get a better cooling performance from your water radiator then from your air radiator, water cooling can be more efficient

You can get a much larger heat transfer from your processor to the water, but this extra heat must be transferred at your water radiator as well. The problem is the driving force. The driving force for heat transfer is proportional to the temperature difference and the area available for heat transfer. The temperature difference between water and air is much smaller than the temperature difference between the processor and air, but since you can get a much larger surface area at your water radiator this problem can be overcome.

Of coarse this is a very simple explanation, but in essence it is correct. In the end the air must cool the radiator (directly at the processor or indirectly via a water loop).

[v0dka]

The answer is.... 42!
