Been using these fans for about a month now and have no complaints. Using them as front intakes and at 35%. I love being able to drop my temperatures by 10 degrees just by pushing these fans to 100%. Though many people say these fans sound like a jet engine at 100% I have to disagree; I've heard pre-builts that are louder than these fans. They feel sturdy enough that I can stand on them and the brown accents actually compliment my blue and black build and I can always order replacement sound pads or just take them off.
