A bit of backstory:
When I built my current PC in early 2015, I installed a custom water loop (soft tubing) for my overclocked 4790k and reference GTX 970. The loop ran great for years with little maintenance other than routine drains/refills (using a bio-cide agent and distilled water). Recently due to some hardware changes I removed the loop and installed a Hyper 212 EVO back, which works fine for my current mild OC, but I do sort of miss have a watercooled build for some reason.
My real question today is this; especially considering Ryzen 3000 series dropping today (I think?), in my situation, would you bother going back to watercooling? I would like to upgrade to the 3700x pretty soon, and maybe a RX 5700 if it looks promising post release. It seems components are a lot more enegy efficient these days (unless you go full 9900k/threadripper), so I'm wondering if it's worth the extra cost, especially as a student), to buy a new pump/res combo and go back to water.
