I know you can't always believe what's on the box. But...
Better said, you can never believe what's on the box.... tho ina sense, the data is true, it's how they present it. Fans will sometimes deliver what they say on the box but under conditions that no fan was ever installed under.
Typically, you can depend on them delivering about half

Cougar advertised:
Max Airflow = 70.5CFM
Static Pressure = 2.2 mm H20
Cougar delivered:
Max Airflow = 35.0CFM (49.6%)
Static Pressure = 1.0 mm H20 (45%)
Nidec advertised
Max Airflow = 58CFM
Static Pressure = .080 inwg = 2.03mm H20
Nidec delivered
Max Airflow = 37CFM (63.8%)
Static Pressure = .047 inwg = 1.2 mm H20 (59%)
As you can see the specs say that:
... they can deliver the 58 and 70 cfm .... but only against 0 SP ... and condition which will never exist
... they can deliver the .08 and .082 SP .... but only at 0 cfm ... fan isn't doing anything for you at 0 cfm
Therefore much like monitor response times, advertised specs have no bearing on realty. 1. Use a respected test site to get real data. 2) Observe the above graph... the fan with the highjer cfm and higher SP will deluver less cfm and less SP once installed.
The chart linked below provides a reliable rating of fans based upon performance and noise. It's a bit outdated, the Silent Wings 3 are right up there with the Phanteks.

However, the best option available to the OP, for the lowest price is sell the card and replace it with a decent AIB card... avoid reference and EVGA SC cards and get a good AIB card
