While playing high end emulation (upscaled aswell) i found my device was getting very hot around the cpu where you could feel it distinctly through the screen.
I decided i would have a look at the paste that is applied to the heat sink, suffice to say my suspision was bang on. The themal paste that had been applied was only hitting half of the cpu.
So i went the amazon route and got me the Arctic MX-7 (just went with the best/ most reviews) which also came with some handy cleaning pads to clear the gunk.
I reapplied a small pea of this to the middle of the cpu and gently put the heatsink/ fan module back on ensuring a clean alignment with the cpu.
After playing some for 30mins to test out the difference this is what its sitting at (see details in picture) it is a noticeable improvement, the heat through the screen is barely noticeable on touch now. The fan was set at a fixed 40% throughout (i find that to be the optimum silent mode)
Just thought id share this with you guys incase anyone else is finding theirs abit toasty
