Really glad to see you picking up new sponsors
I'd previously thought (after the rebuild) that it was a teal pastel coolant you were using, noticed on the last post that it was actually mesh around the tubing!
I've been thinking about whether I should consider the extra expense to get a blitz kit and give everything a proper clean (for my 280 and 240) as the rads have been sat unused and mostly drained for quite a while (1yr+)
I've been using an aircooler since and was considering just picking up a better one (TT PA or Phantom), as it would give me more freedom on cases (cos 280 Monsta and a 480 that I haven't used yet...)
Looking forward to the next update
