The Ultimate Water Cooler Project... - 2005/02/24 18:49 These days if you want to overclock your PC with the standard off the shelf heatsink and fan are just not upto the job. They provide sufficient cooling at the CPU's default speed but with increasing the Core speed and voltage this produces alot of heat and we all know heat is bad for CPU's, GPU's and memory and the overall system.

So this story is about my Water Cooling Project which to be honest with you has taken me about 2 years to have the bottle to do.

I have been look at various water cooling solutions over the past few years and one thing that has always struck me about them is that the water reservoir are very small indead, some only holding a couple hundred ml of water, which requires addional radiators and fans to cool the water being pumped round the system.

In my opinion this defeats the object for water cooling as its not only for cooling the system but also for running a silence system.

So I started to gather parts and components for my project, it started of with in my opinion with the best case money could buy the Yeong Yang YY-0221 Server Cube. Here is a link with some nice pictures of the case.

It cost around £180 inc vat at the time. What is so special about this case you ask? It has two chambers inside it, on one side of the case is the motherboard chamber and on the otherside is the harddrive/CD-Rom and power supply chamber thus keeping the vital compents free from clutter and heat build up of the other compents.

Spec are...
- 6 x 5 1/4 bays
- 2 x 3 1/2 bays
- 8 x 3 1/2 Harddrive bays (cooled by two 60mm fans)

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:03 Second on my list was a office 18.5 litre Chilled Water Dispenser. But these things are not cheap and i was trying to do this on a tight budget. A new one is about £300 to buy.

Luckly I found one on Ebay that was in a office in Edinburgh that was shutting down and it was on Ebay for a whole £10 quid yes a tennar. I found it strange how no one was bidding on it, until i read the full auction page. It stated that buyer must collect and as i was working in Edinburgh at the time this was not a problem for me to uplift. So I placed a bid for £10.50 with a max bid of £80. I checked the Auction to find that no one else had bidded on the item so i won it for £10.50. Could not believe my luck.

Next on the list was a good pump and water block. So I ended up going for the Water Chill Antarctica Block at a cost of £40.

The water pump I decided to go with was the Danger Den DD12V-D4 at a cost of £45.

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:10 Putting the thing together...

I decided to use the tap on the water dispenser as my water outlet to the cpu as it has been cooled by the compressor chamber just above the tap. This was quite easy to do with no major modifications required.

This I ran 10mm/6.5mm diameter piping from the tap outlet back into the rear of the water chiller where I had decided to place the Danger Den water pump.

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:12 Which then I joined to the Danger Den Pump at the rear of the Water Chiller.

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:22 I then took the outlet of the Danger Den and attached it to the inlet on the Antarctica Water block, it is the centre pipe in the picture below (please note that the Antarctica water block has 3 pipe connections 1 for water in and 2 for water return thus removing the hot water faster from the water block than anyother water block on the market).

So I feed the pipes through the back of the PC case, using the redundant COM port slots. You may ask why I never fitted nice connection taps here?

Due to the high pressure that the danger den pumps water at, I did not want to risk a leak. It is capable of pump 1200 litres per hour.

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:36 This is when my problems started...

I actually ran out of piping. Due to the height of the water cooler I had to run the return pipes back to the top of the water bottle so that by the time the hot water had returned back to the CPU it had been cooled by the compressor at the bottom of the water bottle. So the only option I had was to travel 40 miles to get some extra piping or put the 2 return feed's back into 1 return feed.

So I put the 2 return feeds back into 1 this take place about 2 feet from the water block to stop any back flow of hot water.

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:44 I then placed a small hole in top of the water bottle and filled it with deionised water from halfords (battery topup water) this cost me about £20 for 20 litres.

You should always use deionised water as it has very low conductive properties, so if you were to have a leak it should not damage your components. It also prevents lime scale from apearing in the water supply. I then placed the return feed from the CPU block into the top of the water bottle and sealed it with water proof silcon sealant from homebase.

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:48 The Danger Den Pump comes with a 3 foot 5 1/4 inch pc power connector. So the pump is power direct from the pc's power supply at power up.

Re:The Ultimate Water Cooler Project... - 2005/02/24 19:57 The big power up...

I fired her up, holding my breath. It took about 10 seconds to clear any air trapped in the piping. which you can easily hear until it settles down to a almost silent operation. I was really suprised at how quiet the pump was you could hardly hear it.

Oh sh*t leak leak leak...water was flowing out of the water bottle around the bottom where it meets the water cooler itself. Doh! I forgot about the laws of gravity here. Due to me making a hole at the top of the water bottle there was no back pressure to stop the water level from dropping even though the system was completely air tight.

So to stop the leak I had to turn my project into a snow cone of silicon sealant to stop the leak.
