The Big Question. Air or water? - Page 3

post #21 of 37
NamelessMC...yes, water has 23x the thermal capacity of air, but in the end, where does the heat go? to the rad. and how does the heat leave the rad? air. so either way, you are stuck with the fact that the ambient temperature dictates the CPU temp. true, it takes longer for water to reach the max load temp, but if you run a CPU at load for 24hours, i doubt you'll see much of a difference between air and water. Plus, all the heatpipe coolers have a liquid inside of them anyways...

The surface area of a radiator > any retail heatsink on the market right now. It's a combined effort. The water has a higher heat capacity, a higher thermal conductivity, and it's able to transfer the heat to a separate device that dissipates the heat more efficiently than any heatpipe/heatsink. Sure, air pushes the dissipated heat from the system, but the air pulling cold air into the radiator is more important. The radiator evaporates the heat through its fins and then colder water circulates back into the system.

Regardless, everyone posting in this thread about air did nothing but theorize and argue without facts.

The best water is no longer $600+. You could get the best water for a full CPU/GPU loop for less than $350. Anywhere from $180-300, you could have a water cooling system that takes your system to a new level of frequencies. Of course it has its cons, but it wouldn't be as popular as it is, if air offered the "same performance".

watercooling systems take ages to config, more danger if leaking
aircooling's quick to do and less risk

but that's what I think anyway

Ok i can see there are alot of opinions out there for the different types. I've been keeping up with my reading elsewhere and i understand now that with both WC'ing and air cooling room temp is the main limitation in both (correct me if am wrong). Your temps can only go as low as the temperature inside the room on vital components like cpu's and gpu's.
I've read up on Thermoelectric coolers like the ultra chill tec which claim and have been benchmarked going around 20 C under the other temps. so wouldn't a tec be a better buy than air and water?
Don't get me wrong i do realize that air dissipation is still a big factor, am just looking at the temps on the component instead of at the heat spreaders.

I ran a Thermaltake Big Typhoon on an AMD Athlon64 X2 4400+ at 2.4GHz and it only went up to 40C at full load. I would get a Tuniq Tower 120 and some Arctic Silver 5; you'll never pass 35C even in stress tests and suicide runs.

My Big Typhoon was stock and was applied via Arctic Silver 5 Thermal Compound. My vCore was stock. I highly recommend getting a Tuniq Tower, Big Typhoon, or Ultra-120 CPU Cooler.

Why wouldn't it be as good? You can feed 12v with or without a fan controller.

The problem with the tec coolers like that is the long term reliability of them, you'll see a lot of posts from people who have them talk about having to replace pumps and stuff after just a month or two.

As nameless pointed out, watercooling very effectively transports the heat away from the cpu/gpu to a radiator that has a much greater surface area than any air cooler on the market. WC'ing is still in essence air cooling, it has just been transferred from the limited space of the CPU area to a much larger and more effective area where the radiator is. Additionally, heat has to be conducted from source to target, the greater the difference in temp, the faster the flow of heat. With watercooling, your water temp varies very little across the entire system and stays very close to ambient so your temp differential will always be high. This is not the case with air cooling even with the ability of heatpipes to transfer the heat more evenly throughout the heatsink

Is there a problem with that example of a tec i gave? or are all tec's prone to components needing replacement? Am just looking for some seriously powerful results. am planning on doin some serious overclocking and u guys complain about ambient temps, lol i live in the bahamas we hit 80-90 degrees a few weeks before summer started.

As u can see hoping for just about ambient temps aint much of an option for solid benchmarks.

Properly set up, TEC's can give you incredible performance gains, but you are looking at a full water cooling setup to properly remove the heat that a TEC creates in addition to the heat it will transfer from your CPU. The TEC's in most of the off the shelf solutions like the linked one are fairly low power. You might want to check out some of the information in the TEC cooling section
