How to clean a GPU block?
So I was doing a rebuild using some new and existing parts and this is my first vertical GPU attempt.
The card had been running in my old case since summer 2025, that's the age of the GPU block. Though the rest of the loop was older.
My new case has, 3 new rads (all flushed multiple times before use) a new CPU block and new pump and distro plate.
I was running some EK Cryofuel Superflush for 24 hours and noticed that there was a good deal of crud / gunk caught in my GPU block.
Truthfully I didn't look too closely when I was disassembled my last build so it could be that the block was like this in the old build but because it was mounted horizontally I just didn't see it.
Big question is what's the best way for me to clean the GPU block?
Thanks.
