We have developed an event-by-event relativistic kinetic transport approach to study the build up of the anisotropic flows 
for a system at fixed 
. The partonic approach describe the evolution of massless partons which imply 
as Equation of State (EoS). We extend previous studies to finite partonic masses tuned to simulate a system that expand with an EoS close to the recent lQCD results. We study the role of EoS and the effect of ratio on the build up of 
up to 
for two beam energies: RHIC energies at 
GeV and LHC energies at 
TeV. We find that for the two beam energies considered the suppression of the due to the viscosity of the medium have different contributions coming from the cross over or QGP phase. We shows that in ultra-central collisions (0–0.2%) the have a stronger sensitivity to the T dependence of 
that increases with the order of the harmonic n. Finally, we discuss the results for the integrated flow harmonics 
in ultra-central collisions pointing-out how the relative strength of depend on the colliding energies as well as on the freeze-out dynamics.
