Improving Internal Laptop Cooling (Latitude E6430)

[Paarthurax]

Good evening everyone,

So recently, my friend let me borrow his thermal paste that he got with his CM Hyper 212 and I used it to replace the pre-installed thermal compound on my Dell Latitude E6430 laptop.

After the temps were decreased by about 10 degrees Celsius, I was wondering if it is possible to cut out and place a thermal pad (like the kind you find on graphics cards to cool VRAM) on the HD4K graphics unit, because the chip doesn't actually make contact with the heatsink, instead it just hovers above the chip about 1 millimeter.

In other words, could I fit a thermal pad in between that 1mm gap between the chip and the heatsink, and if so, what improvement in temps, if any, should I expect?

If anyone would like to know, the reason is because when the HD graphics and the CPU are both maxed out when playing games the heatsink itself can't cool all the load and temps fly above 100 degrees.

Thanks everyone for the replies, and have a great evening.

Specs:
Intel Core i5 3320m - up to ~3.29 Ghz
Intel HD Graphics 4000 - up to 1.2 Ghz
8GB PC3 12800 RAM
(Not much else that I would assume are too important, but just in case...)
Intel QM77 Chipset
Samsung 840 Evo SSD
WD Caviar Black 320GB 7200RPM HDD
(No, unfortunately for me I am stuck with Intel HD4K and am without the NVS 5200m)

The GPU itself is actually on the CPU die, not on the northbridge chip. The northbridge on newer motherboards does not get hot enough to need an actual heatsink. If it doesn't come with one on it, it doesn't need it.

Ah yes, I thought if the graphics were on the CPU chip it would be as a separate die and not unified on the same die as the CPU. I guess that was old knowledge on my part, and thank you for your reply!
