Laptop cooling isn't really considered liquid cooling even though the copper heat pipes do usually contain a small amount of liquid. The liquid is turned to a gas which is sent to the end of the heatsink and cooled by the fan and then returns as a liquid. You can try to find a replacement heatsink for your machine but usually a thermal compound repaste and blowing out the heatsink fins and fans will reduce your temps. It's good to repaste once a year or so. 

oh yeah, when I was cleaning the CPU fan there was a T H I C K layer of dust which my dad and I (who also has pretty good knowledge in building computers) thought was a protective layer. Lol!

Hi, Sorry for the very VERY late reply, so uh I did replace the old liquid metal ( or the remains of it) and replaced it with a thermal paste. Temperatures are MUCH lower than before BUT. The GT 650M which I have in this laptop seems to throttle down to about 135 MHz (or maybe the motherboard couldn't withstand that.) I do get about 69-80 Degrees in gaming now compared to the massive 99 Degrees for running a low-end game. Unfortunately, I ran into an issue when i was replacing the thermal paste. I have broken the left hinge of the laptop's monitor and the (bracket?) thing snapped off when unplugging the alien FX keyboard which has seemed to completely ruin half of the keyboard and the alienfx colours ( if i selected a full blue colour scene, then the eyes would be purple and the Mouse-pad would only change 1 colour. Blue.)

That hinge you need to replace as that’s what’s causing the screwup with your colors being mismatched.

i know this isn’t the same product but when I had my x51 R2 back in 2018 every time I’d change the colors it would literally make the colors such as red to pink or blue to green.

i ended up reseating the cmos battery and disconnecting it then the problem got fixed!
