I bought them with reservations after reading the above comments....let's see...I have them for air extraction in my PC...the LED appears faded in the photos but it is actually a vibrant red and nothing like what it seems...as for the RPM, because they are low, they still have a good airflow, so it balances out...they are quiet...

Relatively mediocre! The cable connects directly to the power supply. It could have had a cable that connects to the motherboard instead.

Do not be misled by the photo, the LED is not as bright red as it appears in the picture! Actually, it is a regular red, not even a bright one as it shows! However, for the price of 6 euros, it is not bad
