So wait, I need to know something before I risk my PC like this, will be building water cooling for my S2E this week...
What was the main cause of this?

1) Pure PC
2) D-Tek Liquid F/X
3) Pure PC + D-Tek Liquid F/X
4) Faulty Swiftech CPU Block
5) ASUS Fusion Block
6) Other/Dirty Components/ Faulty components

Could it be the combination of those liquids by any chance? I plan on using Feser Coolant
If there is any chance the responsable is the CPU block, then I would be surprised specially from Swiftech!
If it is the ASUS Fusion block, then I dont understand how many people using Maximus Extreme block never got any problems, as well as the Blitz Extreme block. If it was for any reason, then I guess I would be better changing the heatsink, but I would like to confirm this before spending money on more heatsinks.
If it was because of dirty components, then that would be different. I plan on cleaning mines with a filter and while doing the leak test.
