Phanteks release their new Halos Lux RGB fan frames

These do look good and can improve the general aesthetics of your case, however the 140mm version reduces the airflow, the actual diameter of the the RGB ring is 125mm which is 10-15mm narrower than my Noctua fans. The restriction is obviously on the tips of the fans which reduces more airflow as they move faster than the rest of the blade. When comparing thermals on the CPU, there is a 2-6°C increase from stock temps. I'm seriously thinking of sending them back.
