I learned most of what I know right here on OCN, some youtube channels that helped me are jayzcents, modzoo, and singularity computers. PPCS is a great etailer site, sort of the #1 spot right now at least in the states. Yes FCPU is gone but modmymods is coming on strong, newegg are microcenter on on board now, there is always Amazon, and even Walmart.com is starting to carry the stuff if you can believe that.
Now is a great time to be water cooling, either with AIO's, kits, or full custom loops with prices varying accordingly.
Google trends will disagree with you. Overclocking and watercooling in general has been on decline for a long time now to pretty much stay steady enough that it has not totally disappeared.
There are a lot of good sites that are gone or have simply stopped updating. It will take a new generation of young ones to have enough interest in overclocking to make it popular and mainstream. Skinnee
stop updating due to being bored of this hobby and has pretty much moved on. He was a great source for radiators, fans, and blocks. Now there is pretty much nothing like that anymore except for big name sites who do reviews.
Most of the things I learned was not on Youtube but on XtremeSystems.org. They had a lot of Pro overclockers there that knew what they were doing and had recorded batch #'s of CPU's and their clock rating. Of course now batch #'s don't mean much anymore for the believers as Silicon Lottery has proven for Skylake. Of course Skylake has yield issues so that has to account for the quality of the silicon too. AFAIK, Walmart itself does not carry watercooling gear. You can't count the third party sellers as they are using Walmart as a storefront to sell their products.
If you want a list of the existing water cooling retailers left:
R.I.P. Jab-Tech, that was my favorite place to shop because of prices. I'll say it again, watercooling is a small niche market. We only represent a very small portion of the PC community. Most people just want their PC to work.
