Acer Aspire V3-772g suddenly dropped in performance.

Hello,

I've bought the v3-772g around 1.5 years ago, and it used to run really nice until a few days ago.
I woke up one morning to see that GTA V runs at 35-40 fps even on the lowest settings, while a few days ago I was able to get 55-60, mostly high settings. Then I got curious and tried to run some other games in my steam list (CS:GO, Smite, Chivalry, Paladins) just to notice the same ~20-30 fps drop, depending on the game.
I'm basically going with an i7-4702MQ @2.2-3.1 Ghz quad-core; 8Gb DDR3 RAM; a geforce gt 750m 4Gb; 1Tb HDD.

I've checked my CPU temperatures with HWMonitor and they're around 37-40C idle, and they go up to 90C while in full load. GPU sits somewhere around 75C in full load, it doesnt even run in idle.

Things I've done:
-opened up the case to try to clean the dust build-up, only to see that there was no dust blocking the vents or the fan;
-updated GPU drivers;
-reinstalled windows since I've got separate partitions on my hdd;
-checked my power settings, my laptop is set to max performance both in Power Options and in the nvidia control panel;
-checked the overall usage of the parts: Gpu is mostly going 98-99% while the CPU is usually at 70-80%
-tried to find older temp records/screenshots to compare, but I didnt. Yet I do not think they have increased a lot since I used to play with the laptop's keyboard so i'm pretty much used to how the full load temps feel at touch.

The laptop has never shut down by itself so I don't know if it is an overheating issue. I've also got a CoolerMaster NotePal U3 supposed to kill some of the heat. Doesn't really seem to do it though.
So now that I have basically no idea what to do, any help would be greatly appreciated.

Well it seems that Speedfan won't even detect my fan. I also tried to check HWMonitor and it won't detect it either.

I've turned off the cooling pad so I can hear it clearly, and it seems to behave just like it did before. It may run just a little slower, based on how the air flow coming from the vents feel.
What I find weird is that when the cooling pad is on it doesn't seem to reduce the temps as much.
Also while I was trying to see if the fan is making weird noises I found that actually the first core of my processor was actually sitting around 68-70 degrees, while the 4th one was at 92. I then opened task manager to see if somehow the cores were not used equally, but apparently they were.
Now I really wonder if it's a thermal compound problem since it seems that a part of the processor is actually getting cooled down or if it has something to do with my cooling pad's fans since I moved them around recently.

Hopefully I can get my hands on some thermal paste soon enough. I'll reply back here if that fixes it just in case somebody else has the same problem.
Thanks for the help, I really appreciate it.
