Running Your Radiator Outside For Subzero Temps

Recommended Posts

Posted · Original PosterOP

I live in North Dakota where subzero temperatures are a regular thing in the winter. Am i the only one who routed their radiator outside my window for -10F ambient temps? It works incredibly well.

Thought this would be a fun discussion. Thanks guys.

The idea is not old.

Linus did a whole room cooling this way.

Whole Room watercooling!

 

It works but you risk condensation if the fluid gets too cold or the actually frosting up due to the fins/rad building up frost if it's let to heat cycle. The reason why the whole room watercooling setup at Linus's didn't have issues was due to a constant heat load and temps not going below around -20C on the coldest of days.

This idea started when my q9650 started to become a major bottleneck. When I was ordering A new CPU and motherboard i decided to try and push it to stupid limits because why not. I used a specialty automotive anti-freeze, and silica gel paired with tons of dehumidified airflow. I believe I achieved 5.2ghz. Fun times

Just for clarity, ambient temp isbroom temp so its probably not -10.

Old idea, it obviously works, but it also obviously causes condensation issues, which in turn requires the system to be adequately protected. Subzero temps also require a coolant capable of staying liquid at those temps.

 

So yes it works but realistically it requires a bit more preparation that just hanging a rad out the window during cold weather :P

Hi NachoGenocide,

 

(chuckle) I recently had a problem with my temps getting to cold. My apartment building has the heat way too high, so I have to leave the door next to my computer open to cool the place down. Last week I woke up and kinda freak out about the temps on my system. -5c on a water cooled system? 

 

Since your from a region that has similar shitty weather to mine, then the thing that you have to worry about is freezing your cooling liquid. This can cause your radiator to crack, (just like a car), or burning out your pump as it tries to push the pre-freeze slush through the system.

Linus lives in Vancouver, where if the temperature drops to 15c/60f people break out their winter parkas!

Too much effort for zero gains. I could just turn down the heat.

My problem is that I can't turn down the heat. I actually have it turned completely off and it's still to warm for me. BTW, I'm originally from the LA California region, so I'm not a huge fan of the cold!

I don’t like the cold either as I can’t play like that. But the pcs produce too much heat. Nothing opening a window won’t fix. 
I’d need some very long runs and strong pumps to do that with a lot radiators or large ones.

Also... the reason whole room watercooling was doomed to not be great was because they didn't insulate the lines. Instead they had like 20 meters worth of copper line directly throwing heat back into the room heh.

 

Doing it right, things have so much more potential than LTT showed haha.
