The Delta 80 x 15mm 11 Blade High-Speed PWM Fan is a slim fan with a lot of cooling capacity. This little fan kicks out nearly 48+ (max) cubic feet per minute with a mere 15 mm depth. The fan makes 41 dBA (max) of noise for a better than 1:1 airflow to noise ratio and uses a standard 4 Pin PWM connector so your board can contol the speed automatically.

Bought a pair of this for my build. The fans move a lot of air at high speed, normal airflow noise, not the motor. But at low speed 40% or less the motor make an awfull clicking noise, not great when surfing the web.

Great volume of airflow in a small package, high static pressure, PWM controlled. This fan works wonders for cooling the back side of my motherboard processor socket. I''ve owned alot of fans, and this one from Delta really moves the air, only becomes noticeable when I am O.C. or the system is really loaded. About the same noise level as a video card fan at full speed. It''s PWM ability keeps the noise down when system is idle or low demand. So if your looking for a small fan for the back side of the motherboard that has to be a 80 x 15, the is the puppy!
