Would a liquid rad be quieter than an air cooler?
Not much I can do about my GPU fans really unless I void the warranty. I've found it has resonance at certain RPM, but I've resolved that with some silicone washers and manual fan override when idle. In terms of pure decibels though, it's still very loud.
I know performance wise, liquid is better, but in terms of dust will it be the same, better or worse than air? I predict if I bought any heatsink, the rad will be coated in dust within the year despite trying to keep on top of it.
