Open Box Alienware 17 R4: Keep or return?

I was able to nab an open box Alienware 17 R4 for ~1000 with the following specs:

Intel Core i7 6700HQ
NVIDIA GeForce GTX 1070
16GB DDR4 RAM
1TB HDD +128GB SSD

Now, as soon as I got it home, I tested it to see if it has the core temp differences. I ran OCCT, and the temps maxed out at:

Core #0: 90
Core #1:72
Core #2: 93
Core #3: 71

Without any throttling, and once the fans kicked in they settled at Core 0/2 being ~84 and Core 1/3 being 68.

I repasted and repadded with Grizzly Kryonaut...
