Hey guys, I rrcentley bought a can of compressed air as my liquid cooler is beginning to make clicking sounds from dust, I want to clean my liquid cooler and fans without takig them out is that ok or should i take them out? I can also see the radiator is really dusty when pointing flash at the liquid cooler, its only been with me for ablut 6 months, i have never cleaned it.
Depending on how much dust/debris/furballs you have in your cooling assembly, you're either going to have to tear down the entire system apart, with the fans off the radiator to get to the dust on the radiator and the fans.
Ideally you should remove the components, give them a good clean and reassemble the components to the system like you would when you've opened them up for the first time.
You could also read through the Closed Loop Coolers section in the watercooling sticky.
