Hello. I own the G752VY and it's summer here where I live. The temperature is absolutely not hesitating to go over 35 C. In winter my CPU temperature is around 75 C which is fine but now it goes to 90 C and it is throttling (checked with HwInfo64). I can also see my game get all choppy and laggy. The CPU starts throttling as soon as it hits 2 hours of constant gaming. I never play for more than 2 hours straight, even in winter so it's not that big of a problem to exit my game and go do something else. However I'm really worried about damaging the CPU. Can it even be damaged? I exit the game as soon as I see it stutter so I don't let my CPU stay in 90 C for long.
What can I do to help it cool down? My fans are not blocked by anything and my laptop is on a hard, solid and straight surface. Thank you.
Thank you for all your replies so far. They've been really helpful.
I doubt I will go for a repaste because I am not capable of doing it myself and by no means after my previous experience with ASUS RMA am I going to send it back to ASUS. One last question. If I make my CPU fan work on 100% every time I play from now on, can that damage the fan?
(If you are curious, basically I sent my G751JY because the battery died and was in need of a replacement. 2 months later it comes back with screen bleeding (the battery had been replaced) that wasn't there before so I decided to send it back. Throughout the next month every time I would check for an update on my service status they would reply "We are running tests on it". This made me furious because what kind of tests does someone run on screen bleeding? I even went to the point of bringing a friend of mine who's a lawyer to the retailer and he spoke with the manager. 2 weeks later they call me and give me a full refund and thus i bought the G752VY. This whole story lasted for 4 months).
I'll keep that in mind but I hope that I won't ever need to recall that information. About the CPU fan, can it be damaged if I make it work at 100% when gaming from now on?
And one more thing I'd like to ask is; I installed my A/C system a few days ago. During the last month (June) I've been running my CPU at 80-85 C all the time when playing because I thought that it's something normal because it's summer (same thing happened with my G751JY, in winter my CPU was around 75 C and in summer it went to 80-85 C, that's why I thought it was normal). Given that I've been playing for 2 hours before taking taking a break and maximum hours of gaming per day was around 6 hours, how does that 80-85 C affect my CPU in the long-term?
Fan longevity is reduced under sustained high-duty-cycle - meaning that if you keep the fan spinning up at high (or at max) for long periods then yes it will shorten its life. Burn out the bearing, mostly likely, or perhaps the motor, possibly even seize it up through some sort of electrical failure.
I don't know the part/model numbers or specs for the fans ASUS installed in that machine. They're probably good or excellent (but not truly superior) quality, probably rated to last about 2-3 years of "heavy/continous" use or maybe 3-5 years of "average/normal" use. Lacking any specific details, the warranty on the laptop itself is probably a fair indicator of when the most failure-prone parts (like drives and fans, stuff with moving parts) are expected to start dying.
I wouldn't worry about 100% fan too much. It's probably got a good motor and liquid- or ball-bearing system, built to last several years. It costs maybe $10 or $20 to replace, it might even be the sort of part that's replaceable or upgradeable with aftermarket kits. It might die an early death (no sooner than 24 months from now) in the noble cause of increasing overall laptop performance and adding longevity to the $500 CPU that's permanently soldered onboard.

I really appreciate all the trouble you went through in order to edit those pictures. I'll give it a try but I'm worried about the impact it'll have on performance. As far cooling pads go I was thinking of getting one, if not for blowing air at least for having my pc raised a bit in order to get better airflow from below.
I don't know about you, but I have a perfect temperature in my room, and the ambiance around my PC is fine because the temperature is always the same. I asked the guys from air conditioning servicing to make the A/C in the way that will keep the temperature okay just for my PC.
