Review on EKWB EK CoolStream Radiator Quad Black by Brian Barnes

I bought 2 of these through PerformancePC a few years ago (when they first came out) and just put them into a build. Both failed completely (see photo. Hard to see the water I know) both shut down. I couldn't find any leaks. Show only when under pump pressure. I used to flush radiators with distilled water and never noticed a leak. As for the radiation from EKWB. Stay away! QC is terrible!
