What have you used as a cleaner? Have you tried diluted white vinegar?
That's whats in there right now - very very diluted, with the primochill cleaning kit coming in
What set this is off is the dumb pump block/res design i have - it's designed for in-flow at the BOTTOM, and has huge dead spots if not used that way. That let all sorts of crap build up and broke the EK mystic fog (it doesnt like sitting still for long periods, it would seem)
This meant it had a location with low to zero water flow where sediment would collect -even just particles of the coloured dye slowly aggregating - and if or when it eventually got stirred up, it'd be big particles.
Those would then meet my EK CPU block with its very very tiny fins, and clog shit up. I have a filter in line, but the particles that pass through the filter get caught in the CPU fins - they're way too fine.
Long term i want to get myself a distro plate with a D5 mount, and do away with that drama... but it's not practical with my current case. a 120mm distro plate instead of a rear fan is the best i could achieve, and it's not exactly ideal (although it would make hose routing way easier)
Oh i need to REALLY praise this fractal PSU
1. It really is silent at all times
2. The way the PSU fan stays on when the PC shuts off to vent heat and drain capacitors* is pure genius for longevity and safety
3. I love the size. 140mm vs 180mm is massive. I could fit a bigger rad in the bottom of the case Or even better... i can now fit fan controllers, ARGB controllers etc in that space. Cable management holes built into the case are all reachable again, when some were previously blocked.
4. No matter what unbalanced load i throw at, zero whine.
Load screens at 800FPS, unigine heaven at 600FPS, 4K DLAA? Nope. No whine at all from the PSU or GPU.
And this is coming from a platinum rated corsair, that most people assume would be higher quality
*It wont drain them dry while its connected, but if flip the PSU switch after shutting the PC down it'll spin til its drained. I could do this on my corsair by pressing in the 'fan test' button, too.
