I've been searching but can't seem to find the 'power draw' (Watt/Amps) for the:
  1. Cougar Vortex CF-V12HP 4-pin 120mm PWM fan
  2. Akasa Viper S-Flow AK-FN059 120mm PWM fan
I'm building a new system with the following specs:
--AMD Ryzen 5 2600X CPU
--MSI B450 Tomahawk MoBo
--G,Skill Trident Z RGB 32GB (2 x 16GB) DDR-4 3000MHz RAM
--MSI Radeon RX 480 GAMING X 8GB Graphics Card
--Corsair TXM 850W Gold 80+ Semi-Modular PSU
--Cougar MX330 ATX Mid Tower w/Acrylic Side Panel (pre-installed 120mm Rear Fan included)

Regarding the PC Case, it can accommodate up to five (5) 120mm fans. I purchased 2 each of the above-listed fans. I was wondering should/could I daisy chain them all (including the pre-installed fan) and connect them to a single System Fan Header on the MoBo. Can one Header even handle 5 fans?
 
Solution
NO. Most fan headers are rated at ~1 amp. I usually stop a 2 fans per header, leaving a bit of room for startup current. If the manufacturer doesn't list the current in the specs, assume 0.25 - 0.50 amps @ +12V.

The other option is to go with a fan controller add-on.

I agree with clutch.
Fan headers typically have a 1 Amp max rating.
And most case fans are .25A. So the max number per header would be 3 @ .25A to allow for any spikes when the fans ramp up.
Thanks. If the manufacturers would list the Watt/Amp values on their website, I could do the math and figure it out myself.
