after 6 months i decided to change my cooling liquid.
when changing i didnt drain all and about 1/3 was still in the radiator and hard to get out so i filled it with new liquid.
now i have Feser One F1 Cooling Fluid (UV Acid Green) mixed with EK UV dark blue (water additive concentrate).
is this bad for the components or tubing?
or any effect on the temperature?

 
Solution
This will most likely be bad. You should NEVER mix coolants, as they might start interacting and clogging/jamming your loop and it may cause temperatures to change dramatically or very little. Try draining the loop and starting over.

thanks!, i will get off my lazy ass and drain everything this time.
 


Good luck :)
Personal experience: I was also mixing different coolants eg. feser and ek koolant, and it worked at first, but then my temperatures skyrocketd... I took out everthing and dismantled my GPU and CPU block. Two problems: 1. Heavily corroded (even though they were nickel plated 0.0) and 2. Gunk jamming up everything. So yea... My experience with mixing. 😀
 


i drained it out now completly and its now running with destilled water and new coolant is on its way :)

 


Great! Good luck on your loop :)
