Whole Room Water Cooling Part 2

[13CA350]

Love the people who are like 

"The fans aren't gonna work outside you know that right"

"The water is going to freeze"

"You're just doing all this now even though you're moving?"

A few possible reasons for not using a car radiator:

- It was intended to run at a higher temperature, so maybe it will be less effective at transferring heat than the computer radiators.

- It was intended to run with an aluminium (probably?) engine block, so you may get a bad reaction somewhere when you use it with copper/nickel waterblocks and copper pipes.

- It was intended to run with a mix of water (for heat capacity), glycol (for freezing point depression) and anti-corrosion additives. Without the anti-corrosion additives, the car radiator may corrode. With the additives, a bad reaction with the waterblocks _may_ occur (I really don't know).

 

Better to use the safer, but more expensive, computer radiators rather than gambling 5 computers worth of waterblocks and pipes on an untried component.

 

 

Hopefully they make a Q/A video like they did for the mineral oil pc.

 

A car radiator would have been sufficient.  It offers larger surface area for heat exchange, and more fluid volume increasing the total available thermal mass.

 

A good quality coolant should be selected that has additives that protect against electrolysis and the other corroding effects that can occur when dissimilar metals are working together.  It is not uncommon for an automotive cooling system to have to work with copper, cast iron, aluminum, plastic, rubber and brass... all in the same system. 

 

Linus's idea has merit but is missing a number of design considerations.  By his own measurement at the input and output almost all of the heat that is being removed from the systems is being expelled back into the room.  Copper looks pretty but there is a reason the best radiators are built from it.

 

So if more thought was put into it, this absolutely could have been a success.  If he wanted to get really insane, he'd ditch the external radiator and put on inside the room with a nice fan and a bypass valve and then use the appropriate sized water chiller.  Then condensation would become an issue, but the room would also get air conditioning!

So, I just watched this video and I'm appalled at how Linus connected those SLI cards in series instead of parallel which increased the amount of pressure required to push through each loop and carries the heat of one component to the next.

My personal favorite setup starts by splitting the flow via Y-connector to the CPU and top of the first GPU. Then the output of the CPU to the other side of the top of the first GPU. Then connect each GPU together with two connections in parallel with the output on the bottom of the second GPU on the same side as the CPU input. 

It's maximum flow and no carrying of heat to the next component. 

Shame.
