I just recently did a repaste on my G750 and it turns out my temps lowered down by a staggering 10-15*C BOTH on CPU and GPU
My past temps were 83 max record on the CPU and 82 on the GPU
EACH TEST WAS DONE FRESH AFTER REBOOT -- TEMPS RECORDED WITH CPUID HWMonitor
CPU used handbrake bench, before 83*C, after 71*C
GPU used Furmark (Burn In 15min 1920x1080) before 82*C, after 68*C
The process took me 6 hours, ( of course I will be careful ) but when I pulled off the GPU heat sink, there was crap EVERYWHERE.. all over the board, even under the plastic protectors of the chips.
They use this sort of weird.. "paste" looks like it's some blue-tack like strip you just put down, unless it's machine applied.. it looks extremely formal. It was practically dry in my understanding.. after 9 months use on low-end games ( I play stuff like Warcraft 3 mostly with my friends, and high-end games on the side, temps never exceeded 65-70 on the GPU Tweak report )
I was literally scraping off the old stuff with a paste spreader, it looked like a cracked wall, and crumbled like plaster.
Replaced with Arctic MX-4 (I didn't use silver, though I could have for the main chips on the die, but everything else was quite small and difficult not to make a mess, I didn't want to risk getting it onto the board.)
It looked like this when I first removed it

What ever that paste is that came stock, it's simply terrible.. 10*C I understand is quite the improvement. Also got a chance to clean out my fans which was nice.

I put paste on, yes. All 38 chips. Which used an entire tube of MX-4
I spread my paste though with a paste spreader with a dot in the middle, but I did make sure I put the plate on square.
I'm pretty sure I did the chips on properly, I put on a thin layer on every chip + a dot method to make sure I got the corners and no air was caught under. I'll check with one of those programs and see if any artifacts happen.. I haven't played a game yet.
Those pictures aren't mine, but I will soon show the ones I took.
I didn't take a picture of the dust on the fins, it wasn't too much though. By the way, for future note, if you ever want to clean your heatsink fins, the fan flips open like a door, the first I've ever seen.
P.S. I am not THAT good with peripherals about where you're talking about sockets and so on.
When I posted a question about how to take off the GPU mount, it turns out that since there's 38 chips all pasted with this.. adhesive crap, you need to literally wedge the corners ever softly off of the PCB for a few minutes to break the connection.

Crap. I think I've made a biiig mistake. I'm assuming my paste won't bridge the gaps for long, then. What's the best thermal tape or pads best for the job?
