Really, it’s all to do with how fast the heat can be permanently ejected from the system, almost always as heated air.
Analogised to a storage array, metal heat sinks and water reservoirs are a high performance write cache. Brilliant for bursty loads but once the cache is filled they don’t improve sustained performance.
- p1necone 6y agoThere was a Linus Tech Tips video where they water cooled via just running water from a tap through the system and then dumping it back in the sink - no radiator or fans involved. The performance was of course fantastic, but the amount of water you use running a tap constantly is pretty astronomical so it's not actually practical. https://www.youtube.com/watch?v=CFXyyJyEtVI https://www.youtube.com/watch?v=CFXyyJyEtVI
- sjwright 6y agoYes, hence the strategic use of the word “almost” in my post. :-) In that scenario, the water isn’t a write cache, it’s just sending the heat directly to /dev/null
- paulmd 6y agoThe other problem is the mineral fallout in the water. A month or so later they had destroyed their waterblocks. What you really want is a closed-loop heat exchanger, where the components only touch distilled water, and it gets pumped to a bathtub somewhere with a heat exchanger that pushes the heat out.
