The primary purpose of fans is cooling the pccases, so the air volume test is the first test we make.
This test majorconsideration wind volume which fans sends, in general, the bigger the bettercapacity of the fans, which means it can send / feed more air to transmitheat.
Air volume test
We use a cylindrical duct to calculate thewind volume, which inner diameter is 12 cm, length is
30 cm. In wind volume testwe use the unit CMM, namely cubic meters / minute, its conversion
method is 1 cmm= 35.245cfm, you can manually scaled values by 35.245.
First we use the simulation environmentthat all fans speed is set to 1000rpm,and thenrange these
data as descendingorder. NB fan’s minimum speed is 1200rpm, so it’s not included in thestatistics.
fans air volume comparison at 1000rpm
And then is loaded with overclocking condition,because of the difference of the maximum speed
of the fans, we take the maximumamount of fans speed and summarized below, the straight line
means the averageof these fans. Datalocated at the upper left mean fans are above the
averagelevel, the farther away from the average, the better; located in the bottom right of the
average line were below average, the farther away from the average, theworse.
fans air volume comparison at max speed
In the air volume test, Enermax, Scythe andNB fans are top three, and their maximum speeds are
also higher than theaverage amount.
