Just wondering if anyone has run water cooling for a CPU or GPU but not with a radiator, just a constant steady flow of cold water from the tap? In scotland water is free and overly plentiful... I was just wondering to myself...I wonder what overclocks you could hit with a constant and rapid supply of 8 degree water. I bet it would be awesome.
 
YEah, not thinking it would be a good solution for home use, but just to benchmark and out of curiosity? The water up here is ridiculously soft actually, like zero limescale. My kettle element looks like the day I got it and I've boiled it 10's of thousands of times over many years. I would say if there was a place to test this, it would be here.
 
If you wanted it for benchmarks then get a phase change unit and get sub temps. If you were going to prep the stuff for condensation, might as well put some proper below ambient cooling in.
 
You'l notice LN is required for 'awesome' over clocks, however the gains are never magnitudes above a standard recycled water closed loop system, even when there is 100 odd c difference. The diminishing returns of overclocks from cooling more than what the chips are designed for hits very quickly. I doubt you'd get any more than a few mhz than a closed loop if any. Time spent on fine tuning your bios/system etc will likely result in a faster overall speed.

Water pressure from the mains is not constant, I wouldn't trust low pressure fittings designed for computers to withstand what the mains could potentially put out. At best you'd kill your hardware at worst you'd soak the PSU and flood the room with the live mains.

Thinking water is free and plentiful so it should be wasted, is the wrong mindset.
 
yes it could be done but it would be some serious water bill aswell lol. Hour of surving the web and gaming would net you nearly 300 litres an hour of water.

You would need to keep it at a reasonable 0.8-1.0gpm through the entire loop and oviously not full pressure.

As blackbadger said atleast with a custom loop you have a few litres. but mains would be constant and you could end up with your room like a swimming pool.

Phase change unit and you can run 24/7 at -50 degrees. If you are going to prep for condensation anyway, might as well go the whole hog rather than getting temps just low enough to cause condensation.

Dont want to go that far? Then grab a 1080p external radiator but tbh, your chips wont gain much if at all going from a decent custom water to your tap set up.
 
:D The amount of people who say LN is the only way to get amazing temps for ridiculous overclock need to do much more research xD. Even a weak sauce Phase change unit would be able to run a cpu at 5+ Ghz and not reach 10 Celsius. And if configured correct would still be subzero at those speeds.
 
The best thing for you would be a bong cooler or geoloop.

A bong cooler looks something like this.

Very simple to make and can get you sub ambient watertemps but not so much that you require a comformal coating on the mobo to combat condensation.

A geoloop is a bit more time consuming/effort to make. It requires a trench around your garden around 1/2 meter deep with suitable tube buried in it,connect your loop to it,backfill the trench and fill with water,the buried tube gets cooled by the earth around it.
Two things about this technique,you require Iwaki pumps....2 of these is prudent. And the second is a glycol coolant for winter use.


Both of these techniques are very simple and effective to use.


TEC's are not at a stage where the cooling is worth the power used,plus if you overwhelm the TEC plate,it will do its level best to cook your CPU
Phase is noisy as hell and also power hungry.

If you are creative with the phase unit, you can get rid of the sound all together (my unit was located in the garage with the PC and only the peripherals and screen was in the room i benchmarked in. If you were creative with the set up you could have a phase change unit cooling the waterloop indirectly through an exchange plate if you wanted to go through the effort of tackling condensation and wanted to just use the unit for benchmarking, therefore saving on power and having low noise when it counts.

I find it funny how you think that a bit of manageable noise and extra power is unacceptable to OP while digging a 1/2 a metre trench, getting heavy duty pumps and running a loop through walls into the house is fine.

Because the trench is silent,Phase is not.
The trench costs minimal outlay,a bit of effort for free cooling.
The phase unit is hot,noisy and expensive to run.

Benchmarking is not a true use of a PC,tailoring your cooling solution to singular use is...well....stupid unless thats all your are doing. You would better off with a chiller if you want to go the plate exchanger route.....

I find it funny that you complain about me having tubing routed thru the house and yet you do it yourself to mitigate the noise from your phase kit.....and Iwaki pumps are hardly heavy duty.

Speaking of which....

Still needs a rad to pre-cool the fluid before it goes back to the chiller,they are also noisy in use and are not cheap to run. You are looking at £360-ish for a 395w capable unit tho, which is not a bad deal. I know someone that has a pair of the 500w units in series, it can certainly get the water cold! They also has a nice feature of being able to hold the water at outside ambient to mitigate any condensation issues.

They measure radiators in resolution now? My things have changed :eek:.

It's a nice idea but seems pointless really. As avenged mentions go phase change for constant coolness (and noise) or go with a normal custom loop.

I can't imagine any of the extra chemicals doing much good for the block over time running a straight pass as you suggest. I'm not sure if the copper is coated in blocks but upon turning off such an experiment I wonder if the air in the system could lead to corrosion.

I suggested a way to keep a phase change unit off when you dont need the extra cooling, given the OP is just playing with clocks this is totally acceptable. My suggestion for keeping noise down was based on my personal experiences; you dont need the PC in the same room you watch the screen and use the keyboard in, so no need to route tubing through walls, just have a wireless set up.

Also heat exchange systems are not always loop to loop heat transfer. You can DIY a phase change cooling plate to a waterblock block to cool a loop and switch it off when it is not needed or pay extra for a proper one.

Anyway these posts are all a bit pointless, i very much doubt OP is willing to dig up his garden and drill through his house to set up a loop or splash on a chiller/phase unit and it really is not worth it outside of benching.

Spending too much time in the GPU section these days :D

You should check out those new Freesync radiators though, they sync the cooling needed to your pumps flow rate for optimum noise levels!
