I Have A Hypothetical Question

AirAssault237

38 months ago

Has anyone ever tried putting thermal paste in a water-cooling loop?

Wait a second, wait a second, at least hear me out first:

Thermal paste conducts heat, right? that's the whole point of it. So would it be crazy to assume a thermal-paste-based loop would provide better temps? Obviously something would have to be mixed with it (it ain't called paste for nothing) in order to make it flow.

Discuss below (beyond just "BUTT TEH POMP WUNT WURK")

I have a feeling that even it were mixed with something it might build up in parts of the loop like in the radiators or something.

conducts heat

........right.

Actually if you wanted to get slightly better performance, you could drain the liquid and replace with distilled water. Water has better cooling performance vs. the anti-freeze based stuff they put in the loops from the factor. This is also why race cars use straight water in their cooling systems, NOT antifreeze coolant.

Wouldn't the water become conductive much faster as it will affect the parts much faster though?

What do you mean?

Water tends to corrode metal parts faster than the stuff they use by default now doesn't it?

As such, when it starts to have particules in its flow, itll become conductive over time right?

I would think the tubes should be designed to not corrode over time since they're designed for water. Otherwise I'd imagine that would be a quality issue and I'd be disappointed.

Rusted/corroded metal is basically "iron oxide", which is a chemical reaction between iron (one of two elements in carbon steel [iron + carbon = steel]) and oxide (another word for oxygen, which is in air). I'm not sure whether or not that would be electrically conductive.

But theyre not designed for water in this but the stuff they put inside instead.

As long as don't have any mixed metals, regular distilled water should be fine in a sealed system.

Good to know!

Possibly meaning that the water might conduct heat faster than thermal paste (even though thermal paste may theoretically have higher "thermal conductivity") because water can travel faster through the tubes than thermal paste.

Not that I'm aware of, and it might clog up over time and result in shorter lifespan of the cooler.

I would imagine it would have to be mixed with something other than just plain water so that it wouldn't be sticky.

The big issues which thermal paste would have are: It is very viscous vs water, so it will be hard to move around the loop and also the heat capacity of the thermal paste will be much lower than water per gram put in, so it is going to be less efficient.
