Yeah when i build the machine i got enough fluid for 2 fills of the system, so i popped the top of the spare bottle today.
It have settled a little sitting idle in a kitchen cupboard for +2 years, but no way near as bad as i have seen some other opaque fluids do ( more or less clogging up a system )
I will need much more fluid for my current project, this computer just have a dual 120 mm radiator ( plenty to cool my threadripper )
But the current project it have two dual 140 mm radiators,,,,,,, and two triple 120 mm radiators,,,,,, for pretty much the same hardware, only adding the GFX card to the mix.
On a assumption and my meager math skills, the new computer will filter the volume of air in my living room thru the PC case 4 times every hour,,,,,,, and i am not running the fans at full speed, assume i will need to run them a little over 50 % speed.
I will need filters on my intake.
