Kraken x60 Freon Mod?

DeltaRecon2552 · Jun 6, 2014

Hello all. I just bought a Kraken x60 and I'm rather disappointed with it. But then I had an idea. After my two year warranty is over I was thinking of draining the water and filling it with Freon or some other coolant. Any ideas or guides on this?

That doesn't sound like a good idea on several levels:

1) THe system is only water tight, Freon is a gas at room temp and pressure, so your coolant will boil off in no time and escape anywhere gas can, namely the reservoir and possibly the radiator.

2) In order for Freon to cool something, it must change phases, even if the water cooling system was airtight, it doesn't have the capacity to allow phase-change from liquid to gas to absorb heat, then compression to force it back to liquid and release that heat.

3) Freon can be absolutely nasty on plastics, so any plastics in the system (lines, pumps, cooling blocks, tanks) can be attacked and corroded over time, leading to a failure.

4) refrigerant based setups also include a small heater plate to prevent condensation and thermal shock, or sometimes an insulating foam or goop. Even if all the above three were worked around, any temps below ambient will cause condensation or frosting and could cause a short, or even thermal shock to components.

Well. Thanks for shooting me down and save me the problems. Lol.

Completely agree with Saberus on this.

The upgrades you should be seeking if you want to increase the cooling efficiency of a liquid cooling loop would be a coolant with a higher specific heat for the X60. This is the amount of energy that is required to raise a material 1 degree C.
The link below contains a number of typical liquids available to engineers and to other commercial outlets.

You'll see that water and water mixes are among the highest specific heat fluids, allowing them to absorb, contain and transfer more heat energy than most. This is why automobiles use a water/glycol mix for their coolant.

On the other end, if you had a very high flow rate cooling loop, you could use something with a lower specific heat which would allow for an more efficient drop in liquid temperature at the radiator end given sufficient surface area and heat dispersion but in turn would lower the overall efficiency of the system due to the liquid inability to hold as much energy on transfer. And on top of all of that, you would need a fluid that would not act against the materials used in the entire cooling loop.

It's not meant to rain on your parade, just to save you frustration and possible harm. A full load of Freon released into a closed room could also be a danger for asphyxiation, and liquid Freon spraying from a leak is a serious frostbite risk.

Okay guys. Thanks for the help!
