Will my watercooling system get frozen?

[drightjustin]

Hi, guys
I just got my H100i, and I mount the radiator on my window to suck the cold air outside.
I am worried that my radiator may get frozen in the night because the temp can get as low as -10 celsius.
I don't know the freezing point of the cooling liquid, anybody knows?

BTW,. the cooling effect is fantastic: 4770k@4.5Ghz: full load=20 celsius, idle=0 celsius

According to Corsair, the liquid is made of water and propylene glycol:

So, from a physics or chemistry stand point check this out:

Based on this you should be okay up to -34C on a 50:50 mixture. I'm not sure if that's exactly what Corsair has. Even then, I wouldn't recommend it unless you're okay with replacing the h100i in case of cracking the tubes, damaging the radiator or whatever. I'm not trying to scare you out of it but I'd be concerned about using something in a manner it was not specifically engineered for other than to fill a curiosity. It's cool to see what something can do but I'm not one to play with my computer parts like this.
So, that's just for the liquid. I'm not sure what the tolerance design levels are for the other components so keep that in mind while you continue to do something like this.
I appreciate you being brave enough to try! I sure wouldn't but more power to you! Hope it doesn't cause you any problems! Have fun!

Thanks,

I just want to know how the hell you survive in that kind of temperature. No heating of any kind in your house?

The temp in my house is 25 celsius, but I mount the radiator outside the window, where it is really cold( Boston, -haha)

You are right...My radiator get frozen last night when the temp dropped to 5 degree..

Is your rig ok? What are you going to do then?

put the radiator inside for a while, and all set!
