Moving into colder waters-build log I guess

The chiller is working the best it has though, so maybe with a little colder temps.

Awesome bro, it was just a matter of time before you figured out the ideal setup for your chiller. Maybe you'll see a dramatic drop in temps at the cpu this time.

Still waiting for the thermometer from Hong Kong. I could stick this old F probe in there but it's a lot of work to remove the block and all and I'm not sure just how accurate it is. EDIT: it doesn't even read negative when I stick the probe in the bottom of the chiller @ -10 F

I must stiffen up the gpu loop mix a little as it froze in the lines last night, but no slush on the evap today.

It seems that once the air gets out of the antifreeze it thickens up some or something, because my pump isn't moving as much liquid as before. I need to add some water I guess.

Here we go again.............

Only difference is I removed the submersible from the chiller so it wasn't adding any heat to the equation. Weird shit if you ask me.

Probably wouldn't ever have a problem with LN2 not getting my cpu cold enough to suit me.

Hehe, definitely not bro-chacho and if you wanted to run at -2c or -196c, you control that with the amount of pouring you wanna do.

Have we successfully created another sub-zero maniac?

I'm already a sub-zero snowmobiling maniac.

Does anyone make their own LN2?

No but we've looked into every way possible. They have mini ln2 factories but they run into the 40k price range.

Wow that's way higher than I expected.....I was just looking at one.

How much does it cost to keep a good supply of LN2 around?
