Excellent quality product as at the radiator (with the sober appearance and class) that the fan running on average at 500 rev / min, a little care! noiselessly with ruthless efficiency! Frankly if you hesitate between a feverish watercooling of poor quality, it is worth taking a cooler that takes up more space certe but made quite a job! I went from 35 to 23 degrees for office use and 75 to 80 to 55 in maximum load with an i7 4790k so it's perfect.
