Review on Noctua NF-A20 PWM: The Ultimate 200x30mm Brown Quiet Fan by Gabriel Tomato

I have a Noctua NH-U14S and an extra fan. Great products. I had a noisy 200mm fan on top of the case and thought I'd order one. I even paid 5.99 for same day delivery. Well, it didn't fit. I went to the site and there. Not compatible with my very good Thermaltake Core V71 case. I can't return it because one of the (for me ;=)) silicone screws that can't be used broke. I hear other complaints in the reviews that they break easily. Either way, they make great products, but check the site or contact them before purchasing. It was my fault but I just wanted to share my experience.
