Questions...what causes this...is it the nickle plated barbs?

What's the best way to clean out the ASUS fusion block? what should i use, is rubbing alcohol ok?

I used Primochill PC Pure fluid if that helps.
Wow, that's rush in it? You may have a defective block or something. Make sure you don't add any dye into your loop. If you already did completely clean it and test each block plus the motherboard one, but I think the ASUS block is unlikely to cause this. Good luck!
