Anyone using one of these to cool?

Basically I'm looking at various cooling options and came across this the other day...

Xigmatek AIO-S80DP All-in-1 liquid cooling system (x2 80mm Rad/x2Tank/12v Pump/80m Fan/Copper Block)

700893-A.jpg


Description:

The all-in-one liquid cooling system combines all of the key components we need into an integrative one,
without tedious assemblage, users can have cooling ability with high capacity and efficiency.

All S775 CPU - S754/S939/SAM2

Combines with radiator, pump, water block and cooling fan, the looks of all-in-one liquid cooling system is just like a
single cooler which has the same installation steps with others.XIGMATEK AIO-S80DP is powerful, performing
similar to other internal or external liquid cooling systems.

An all-in-one liquid cooling system design provides quick and easy installation.

It combines dual 80x80mm radiator, dual tank, 80x80x25mm PWM ball
bearing fan inside, 12V DC pump and copper water block.

Any ideas anyone? I like the look of it but should I just go for a thermalright or tuniq?
 
I would spend your money on a decent hsf rather than that item, the few reviews Ive read about it a while ago said its performance is fairly average and only a slight step up from stock solution. Add to the fact its weighty design and general bulkiness I don’t think there’s much going for it.

Yet another compromised water cooling system that gets outperformed by many better air cooling solutions.
If you plan to cool a quad core don’t even consider this item!
 
It's probably the lack of water volume that leads to such poor results. A standard watercooling system relys on the water cooling down again by the time it gets back to the CPU. With lengthy tubing and decent rads it should do it. With that though there is very little water so it's just the same stuff getting pushed around it over and over staying hot.

Rubbish, water volume has very little to do with it. It's all about having decent radiators, pumps and blocks. The only way your statement is indirectly true is that a decent radiator is large and will hold more water than that thing up there. It's the surface area of the radiator that makes it decent, not necessarily the volume of water it holds.

As stated above, if you want watercooling, do it properly. A decent air cooler would likely be cheaper/cooler/quiter/lighter than that all-in-1 thing.
 
I was trying to use common sense. More water volume in the loop means that water that's heated up by the CPU takes longer to get around and back to the CPU. More time = more heat dissipation even if just through the looping and reservoir stages.

So technically I'm right, it just mightn't make that much difference.
 
Fight fight fight!

It's both. How long does it take you to heat a cup of water in a saucepan? Now fill the same saucepan to the brim and time how long it takes to heat it.

More water means the processor has "more to heat".

If rads/pump are crap then a system with very little water is going to perform much much worse. Think of it this way, if I ran a watercooling loop outside (in tubing), 3 times around my garden and back to the CPU then I could push it round pretty slowly but still get great cooling (assuming the sun isn't heating up the tube!). If I did the same with a 20cm loop and no rad, then I'm gonna boil the water!
 
You're both talking about how long it takes to heat up and not the systems capability of dissipating that heat.

This is rather like the debates of using a res or T-line in water cooling. They will both reach the same load temperatures, but the system with the res (in an otherwise identical loop) may hold twice as much water and take longer to reach max temp. Likewise, the reservoired system will also take longer to drop temps back down to idle after load is reduced.

Heat loss from tubes and res's (unless specifically designed to do so) is negligible. Surprisingly, the temperature variation in a loop is very little ~1 degC.

If you only ever stress your PC in short bursts of less then 10 minutes or so then maybe volume might be influential. Or maybe if you had an impractically large reservoir you could extend this further. But for most instances it's all about the components you choose and not the volume contained.

I'm not sure if that's correct. The volume of water will simply alter the time taken to reach an upper equilibrium temperature when under load, and also the time taken to reach a lower equilibrium temperature when idle.

The only place that significant heat is lost to the surroundings is the radiator, so the rate of heat dissipation depends on the effectiveness of the radiator and the flow rate through it.

If you're trying to push more water around a loop, it'll be slightly more work for the pump than pushing less water around a loop, so more water in a system might even increase the temperature on the whole, because of the slightly decreased flow rate.:)
 
To be honest Fiz, you're just nitpicking Darg's reply. His comment was:

The way I interpret that is the total rad size and tubing size in that "CPU All in one" device is too small for decent cooling. It doesn't matter what kind of materials it's made of or how fine the radiator fins are, there simply isn't enough surface area in contact with cool air to compete with a custom watercooling system.

I believe you misread his post and are now clutching at straws. no one has said quality components don't make a difference, but if you take the best rad out there, compress it into a 7cm x 7cm cube and weld it onto the block, I think you'll get pretty *oi no swearing!* poor cooling.
 
I beg to differ. Only the words you have highlighted in red are the valid ones. The actual content of the sentences actually imply that the volume of water and the fact it will just magically cool because the tubes are long are critical factors and that getting pushed around and around a short loop is a hindrance.

While my original reply may have been a little harsh and flippant, it was constructively argued. Thankyou.
 
WTF is happening in here then?

I only asked if the above cooler was any use which the its seems it is'nt.

With that in mind, can some recommend me a water cooling solution for the CPU only. Im not interested in cooling anything else in my system via water currently. I've already got a Noctua U-12F on my chip but would like to take some more degrees off, I can't see a thermalright or a tuniq knocking more than 2-3 degrees off, so would water knock more than this off?

From the review i saw about the cooler it cooled quite well at max speed but was far too noisy to have running at that speed at all times. In which case the Tuniq, TRUE or Noctua would be the better bet as they cool just as well but without the noise.

The question is how much do you have to spend, if less than £150 I wouldnt bother going water unless you source all the bits second hand.

Well cost is no issue really. I'd much rather know that my chip has the best cooling solution on it. I've only just really started looking into this water cooling lark, hence why I just to start with my cpu first and learn from there.

Yes, but that only affects the time taken to reach a stable equilibrium. What this temperature will be depends upon how good the water cooling system is at getting rid of the heat by transferring the heat to the room air via a radiator. Having long hose doesn't affect this, and has a negligable effect on tranferring heat to the air in contact with the tubes as rubber is a good thermal insulator.

If rads/pump are crap then a system with very little water is going to perform much much worse. Think of it this way, if I ran a watercooling loop outside (in tubing), 3 times around my garden and back to the CPU then I could push it round pretty slowly but still get great cooling (assuming the sun isn't heating up the tube!).

Rubber hose is a thermal insulator. All your system would do is introduce massive resistance to water flow, so that the radiators would do a worse job of getting rid of heat, and mean you'd need more a powerful pump that dumps more heat into the loop.
