Well, I wouldn't go that far
though I do think the anti-EK movement at OCN is a bit extreme.
The fittings they make are solid, but a bit overpriced. Their CPU blocks outside of the Monarch are outclassed by other brands, GPU blocks are middle performers, and they have a lot of QC issues as well as problems with nickel flaking off and going zooming through your loop.
I have an EK block on my STRIX and some of the best water Delta performance out of anyone with an EK block on OCN. I got lucky it would seem with a block that was machined properly. Lots of people, especially with FTW3 blocks, showed proof of their EK block literally uneven from the factory causing bad core contact.
Doesn't help that their customer support will treat you like a criminal before they send you a replacement for anything. That's probably my main issue with EK. Nickel flakes off the block into your loop and they claim it's your fault even if you just ran distilled w/ inhibitors.
