air and water are ok but..

so if you lock a box full of 50% of water and 50% of air lets forget about volumes here as in rooms etc

say a cube half water and half air the water will always be a lower temp than the air ?

if so great .. but i cant see it

If you're using that water to cool a CPU, the water will be hotter...

i want to keep my room comfortable without pumpin tons of AC controlled air into the room cause it gets a bit chilly, but dissapate the heat from the pc so it doesnt effect the ambient and therefore not kick in my ac as much. if you see what i mean.

so the thought was a chiller with an external vent so no heat is dumped into the room similar to my ac without me feeling cold but am not sure of the best way to do that

no i dont want the rad outside the room as in the summer i would be worse off tbh than just having my ac on

The problem with a Hailea unit is that it just dumps heat straight in to the room it's in, not just the heat from the PC, but also the heat it generates from actively cooling the water with a refridgerator - typically 100-200W for something sized to deal with a modern CPU. You would need something with a flexible duct and run it to a hole in the wall or out the window and have the waste heat carried out the room like that.
 
yer i have an ac duct that i can use for the unit so thats not a prob tbh i will connect the exhaust from the chiller into my AC ducting ..so any heat from the unit will go directly outside, the only thing is the unit i guess as in the body will also get hot . that may be more easily hadled by the AC so as i dont have to run it so much and sit here cold.. when it kicks in so often..

"If you're using that water to cool a CPU, the water will be hotter..." surely?
the water will remove heat from the cpu then that heat will transfer into the room eventually the room will heat up and the temps will equalise within a degree or so .. im not talking absolute but the ambient will get to close to the water temp and then consequently the cpu temp.. i accept they wont be = but the point is they will grow closer as in +/- a degree or two

tryin to chill pc with less room heat dump is what its about..

is there a alternative to the Hailea? or are they the only really small effective units 250 - 300 quid is okie as a expense i guess so thats not the prob so the 100 range ?

If you've got an ac duct, you might as well use it for your radiator, it'll be a far more cost effective means of getting rid of heat.

Nope. When you start with everything off, everything is at ambient, when you turn it on, the CPU produces 100W, heating the water, which in turn heats the air. For the water to transfer 100W of power to the air it needs to be say 10degC hotter than the air.

Just for example the CPU is 50C when pumping out 100W and cooled with the water at 30C and the air at 20C. The air gets heated to 21C, meaning that the water can no longer transfer 100W so it heats up as well to 31C and in turn the CPU heats upto 51C. As the air in the room heats up to say 25C, the water temp will increase to 35C with the CPU at 55C. Eventually you reach a point where the heat loss from the room to it's surroundings is also 100W, so you end up with the room at a constant 25C, water at 35C and the CPU chugging away at 55C, plus a tiny addition to global warming.
 
ok first damn the mutli quote bit as it still dont look right so...

"If you've got an ac duct, you might as well use it for your radiator, it'll be a far more cost effective means of getting rid of heat.
"
my rad is external but 10 feet from the window and i would rather pipe the chiller along the skirting to that unit i think the benefit from the chilled water ( as in time to heat everything up) will out weigh the heat transfer from the pipes into the room so most heat will still go outside. ( hope so anyway) tbh the cost of the unit isnt a problem anyway as its going to be a little project of mine along with a wave machine type header tank and the cooler water will provide more water density.

"Just for example the CPU is 50C when pumping out 100W and cooled with the water at 30C and the air at 20C.

okie got you .

so instead of chilling my bollux of with my AC better to chill water and get heat outside as effieciently as possible then...

we all know that water is more effeicient at removing heat than air, but ultimatley all water is doing is delaying the process of your pc heating up longer than an air cooled system. as when you water reaches the same temp as the temp in your room it will then gradually increase warming the ambient at the same amount untill everything is the same temp,

obviously the bigger the room the longer this will take but we cant increase the size of out rooms easily. yes you can open doors and windows in the winter but opening a window in the winter will have the same effect as having aircon on all the time. and in an attempt to kool your pc you may have to suffer cooler than comfortable room temps.
so water chiling is the only real answer to nice comfortable room temp and a cold pc.
what a long winded way of asking are there many options other than Hailea water chillers? as sometimes i dont really want to put the aircon on just to keep ambient temps down as the room warms up a hell of a lot

and if i can chill my water and keep pc kool but still in a comfortable room not to hot and not with ac on all day would be nicer

hailea or anyother ideas ?

I drilled two holes in my wall and mounted my rad on the outside of the house ;-)
 
this is my chiller mounted under the floor so i dont get any issues with noise or heat from the back of the unit

this is my pc with what i am cooling of the chiller

pc6.jpg


these are my cpu temps at full load

my pc is near silent now and cooling is fantastic, i love the chiller it was a bargain price of £186 brand new from the bay :)i say go for it mate if your a pc overclocking junkie like me :)
