Yeah, the ad-funded model and how that supports reviewers seems to have damaged well structured and comprehensive independent review sites. It's all in videos or really low-effort stuff nowadays, and that makes it hard to draw conclusions without significant effort - and even then, considerable risk of drawing the wrong conclusions.

I think this affects far more than just coolers; it's simply that for categories that have few options (say, CPUs) it's easier to slog through all the youtube videos, and there still exist a few text-based reviewers.

But cases, ram, motherboard AIB versions, GPU AIB versions... even power supplies often - reviews are suprisingly sparse and hard to compare and rarely comprehensive.
