I have an Omen X with the i7-7820hk and 1080. I am re applying thermal paste and just wondered if anyone could tell me what it is that I have circled in my picture? The die in the top left is the CPU and to the right is the GPU but was just curious what that was I circled. After new thermal paste I'm still getting CPU temps close to 90 celcius
