How many fans do you see in HW Monitor, AIDA, etc. ? I see only one on my G725VT. Is this issue? As I seen on Youtube, it has two fans!

I think they work in tandem. I also see only one in HW Monitor. This would make sense because the heat pipes are somewhat shared. So it wouldn't make sense for one to run quicker then the other.

As seen here:

The Fans do not work in Tandem. If you run a CPU intensive bench that had no GPU load the CPU fan will spin up and same goes for GPU intensive bench with no CPU load.

HW monitor, AIDA and all the others Ive tried do in fact show one fan however that is incorrect, they obviously haven't updated their SMBUS addresses so its not seeing both. No software that I know of actually has their profiles other than ROG Game center. You can however if you want verify that they run independently if you want.
Download and install Notebook fan controller and select ASUS Zenbook UX32LN as the profile (this notebook evidently has the same SMBUS addresses). You can then watch both speeds and control them manually independently. Simply drag the slider one click to the left one slider at a time and watch in amazement as each fan will spin up in accordance with each slider independently of the other fan.

They dont technically share a common heatpipe. There are two heat pipes, CPU heat pipe does extend to make contact with the GPU heat sink but the GPU heat pipe is a stingy SOB and doesnt return the favor! . Easier for you to see for youself that me to explain it. Watch this vid at about the 28 second mark you can clearly see two individual heat pipes.

Technically there are 4 heat pipes. 4 crimped ends = 4 separate heat pipes.

Ok, let me correct myself for matters of technicalities. 2 SETS of Heat pipes.
Either way doesnt matter, They do not run in tandem and are controlled separately.
