Have a Swiftech H240X closed loop CPU cooler. First installed about a year and a half ago. Am noticing a couple tiny algae growths in reservoir. I only use my system on weekends. When should I do a complete coolant replace?
Is it simply at regular time intervals or does it have anything to do with usage?
Is any special 3rd party cleaning kit recommended?
What happens if I don't replace the coolant?
I'm fond of Mayhem's Blitz. Get the pro kit, that includes part one and part two. Disassemble and scrub everything you can, replace the tubing, and use Blitz afterwards. Follow the directions closely - part one is a strong acid (you only use part one on the rads and part two is for the whole loop.)
