OcShoot's WaterCooling journey
OcShoot's WaterCooling journey
Watercooling : because of safetyreasons I have been very
sceptical to watercooling, a leak can cost a lot of money. With a high performance pump
like Eheim 1048 that we used it will only take seconds to destroy expensive hardware since
this pump have a capacity of 600 liters/hour (156 US gallon/hour). Imagine what will
happen if a waterline slips of a connection .....
Getting the cabinet ready :
We had a AopenHX08 cabinet which had been stuffed away for a year which we decided to prepare for watercooling : this is not the most fancy cabinet in the world - but it's very ridgid and easy to convert to our needs.
We did cut a opening for a 120mm radiator fan in the front and did also cut away some "irritating material" to improve the airflow in the cabinet.
Radiator :CoolComputers deliver a 120mm Sunon fan with this radiator. The Sunon fan is a 2.4watt (KD1212PTB3) which is extremely efficient and noisy !

Water cooling without peltier - if you use a peltier you should not connect a additional waterblock to the graphics card since you then will add heat to it,
CoolComputers waterblocks are "crossdrilled" copperblocks and got good finish. Don't expect the worlds best performance since a crossdrilled waterblock actually is a piece of copper with four holes drilled in it.

CoolComputers didn't have a CPU clip ready at the time we recieved their waterblocks. The hoses you see at the picture are not reinforced and they can collapse at the suction side of the pump when the water gets hot enough.
We quickly discovered that water cooling without peltier(s)
would not give more than a good aircooler. We also found that a water-reservoir is not
needed since the water will reach the same temperature after a while anyway. We know that
some people drop ice packs in the water-reservoir to lower cooling water temperature - if
you are one of those persons you need a water reservoir ! There is also much easier to
fill water if you use a waterreservoir since centrifugal pumps not are self priming - by
submerging the pump in the reservoir or install the reservoir above the pump eliminates
Remember we told you that the suction hose can collapse if the water gets too hot ? Well look at the suction hose here - it has started to collapse and the water temperature is only about 40' C ! If we used a system with a open reservoir I am pretty sure it would have collapsed at this moment. What is happening in a closed loop system is that the water expands as it gets hot and actually causes the system to be overpressurized.
For a complete watercooling system you will need a waterblock,circulating pump,radiator with fan,waterlines,hoseclamps,distilled water and chemicals to avoid algae growth. The pump we choosed is a overkill in this system (and maybe in any system) - Eheim1048 pumps 600 liters/hour ! We also used a battery box from RS which were insulated to prevent condensation from the 55Watts peltier we used at this test.
