Do you use rubbing alcohol to clean or some sort of harsher cleaner?

What coolant are you using?

@Br3tt96 I use a non-abrasive (very light) polish, the hard staining didn't all come out especially on the GPU block. 

@TVwazhereIce Dragon's Pastel, the original creators of the pastel series.

This was a 18 months test with the same fluid to see the longevity of the nano-particles, fluid did great but looks like some copper decided to plate themselves onto my blocks. 

I think I'm gonna stick to Distilled water. Possibly with some sort of mix in it depending on what I need

Agreed! If I ever did a loop I'd run distilled. Although, some sort of fluid looks so good. Maybe one day I'll do a loop whenever I get out of college

@TVwazhere @Br3tt96 For something with a little less hassle a clear fluid like Mayhems X1 or Croyfuel would be better. With opaque fluids they all tend to have a minor amount of build up occurring. I've run opaque white fluids for almost 4 years but this is probably one of the worst I've seen it, that being said it's way past it's due date of 12 months.

@W-L would that be an entire fluid, or a powdered/liquid mix I would add to distilled water?

@TVwazhere It's usually a concentrated fluid you mix with distilled water to get your total amount.

@W-L Awesome, I've heard of it before but havent done a crap ton of research (the build isnt until at least 2019) so I'm taking it slow  Browsing the different Exotic cooling pinned threads and all.

@TVwazhere Just take your time doing research, and getting quality components. If you want you can always get a kit to build off of. 

Small update:

Almost ready for the Pastel, leak testing. 

Kits are intriguing but in the end I really wanna go custom, at this point using mostly EK parts with Bitspower fittings (because people wont ever stop suggesting them)
