Chiller over Rad?

[0iD]

Does anyone have experience of running a water chiller, shuch as this one in stead of/as well as a std radiator in their watercooling setup?

That doesn't take the place of a rad, it's a waterblock. It sits on the CPU like how it is in the pic. I have that one without the fans (they don't really do anything on it, they won't save your pc). It's for sale once I find it, given up on the watercooling.

Well that clears that up, cheers m8.

For water chilling the best way is to stick a proper rad outside in the cold, or add lots and lots of ice to your res, or get an old freezer to chill the water (most effective). Freezer is better imo than direct phasechance because its not just doing cpu its gfx and nb aswell if you have w/b for them, and is less risky, sorta...

Indeed. Remarkably effective during the winter with a big rad. Of course it depends on temps outside.

With my large external rad I get relatively good effects just by putting close to a single glazed window (on the inside).

my rads

Want to put them outside. Hopefully that big fan is ok with moisture, some fans moisture will rust the motor. I might make a passive rad (lots of large copper pipe with fins) which I could put onto the outside wall.

Have you tryed outside? my main problem, apart from the fans (new large moisture protected fans cost about £70!), is how to connect it to outside. My dad doesnt really like the idea of two holes through the outside wall, and neither do I, as I would have to make them and I dont know how to make them properly either...

I already hav a big airvent knocked thro the wall behind my desk. Dont think the mrs will take too kindly to a big rad on the outside of the house somehow...
Was thinking of running copper pipe into the loft & into a coil in the main water tank. That must hold 1-2 cubic metres of water & it's constantly getting replenished. An old central heating pump should do the job & they're quiet too. Hmmm best call in a plumber (mi dad) for a quote

Yeah i tried it outside on the window sill of my apartment. My setup is a large passive rad which works very well and when i built the system i left quite a lot of extra piping to allow for some flexibility as to the placing of the rad (my 3/4 inch powerhose piping is quite the opposite to flexible though!). Pics Here.

If i want it extra cold i just open the window and put the rad outside leaving the window open just enough to let the pipes in. This is good if you have the space as it gives you flexibility. And you can move it in if your worried about frost damage when the comp is off.

Nifty piece of engineering there turkster! Impressed.

Thanks 0iD. IT is my first attempt at building a computer but i had a good bit of experience with the practical mechanical stuff. Still I was surprised when it worked!!!!!!!!!!

using a freezer or fridge is only a good idea if the pc is not on for a long ammount of time, fridges and freezers are not designed to handle constant heatsources, even putting something like a piping hot pizza in a fridge can damage it

s'cool! My last foray into extreem watercooling involved connecting the system directly to the (unmetered) mains supply. However, owing to the dubious legality & un environmetally friendly nature of the setup it had to go Worked like a charm tho & totally silent.
Next project, gravity fed/pump assist cooling from header tank in loft. If th mrs lets me

[turkster]

Interesting (the loft tank idea). IT would probably be very effective as the large body of water would have a massive heat capacity hence evening any load/idle variations in the CPU temp etc. Also if the water in the tank is being replenished regularly the water tank temp would probably be close to ground temp which is usually a lot lower than air temp.

Seeing as your going for the full installation coundnt you try exterior evaporative cooling mounted on the roof. That would be fun.

Hmmm...interesting idea....worth investigating...
Getting the idea past the mrs, let alone any planning regs might be different Would be a top project tho.

[turkster]

Yeah planning might be a problem. You could always say it was a solar energy device!! Youd surely get planning for that! Environmentally friendly as it would seem.

yes if it cant handle the heat output the compressor will get damaged from overheating. Fridges and freezers only cycle once or twice an hour iirc just to maintain the temp, remove the thermostat and it will stay on all the time and it should then work well... The condensor may need active cooling if its not good enough...
