Finally got my cabinet's cables managed.
But I had to invert the PSU once again otherwise the main CPU cable wires won't go back and re enter from top.
There was a empty slot at the bottom to take wires below but I couldn't see it before because of clog of wire.
Now when running photshop quadro temp is not going over 74 °C.
When running blender: quadro temp is not going over 78 °C.
This is just awesome and I think all the heating problem was happening because of the wires clog in front of the intake fan.
With the new fans it will be super cooled.
Thank You @dbrown for all the help. You might be busy so not replying any more, but this thread has taught me a lot.
