What thickness thermal pads does a Dell Inspiron N7010 have when new on CPU and GPU

Need to Replace Thermal pads on Dell Inspiron N7010 17R
What thickness pads are fitted from new and what is difference between brown pads and black pads ?
Have 4 black pads and 1 brown pad and grey paste on CPU
(Intel core I3)
Is this how it left factory?
Thanks
Steve

If you are re-doing the CPU/heatsink, use thermal compound; better than pads. Use Arctic Silver 5. The grey stuff that you see is thermal compound. Clean it thoroughly using some alcohol swabs.
