XPS 15 9550 PL Throttling

i have been experiencing this Power Limit Throttling issue for some time now when ever i do anything intensive mainly some CAD rendering and gaming, so i researched a lot and found out that it is very common problem with XPS so i did some repasting and undervolting and put some Thermal pads on the VRM according to some guides which helped reducing the temps a lot from 45C-48C to 33C-38C for CPU in Idle and under load i get 70C max,also the Ambient temps are now fairly low 70C max (before adding thermal pads temps reached 93C).

After all that the issue remains i have some picture to show my temps while gaming cs:go medium setting when i am in game cpu throttles i tab out to desktop everything goes back to normal no throttling ????? can any tell what is wrong with my XPS, i can't do anything but IDLING!!!, browsing and some coding without it throttling.

Everything is updated to latest i even did fresh windows install, i have the i7, FHD, 960m configuration.

the blue highlighted text (Fuses Limit,..) kicks in some times randomly and always when i stress test the system specifically with Aida64 what is the reason for this limit ? is it normal ?

some info and temps while gaming: (with intel dynamic platform and thermal framework installed)
