Hot ambience temperature- Tips for cooling my pc

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.

UPDATE: I searched everywhere for those small, portable A/C units but everywhere I asked they said that they're not that good and that it's better if I get a regular A/C unit and so I did. I installed it, set the temp to 23 C - 25 C, let the room cool down for a bit and launched a game in order to test the temperature of the CPU.
The results are that the CPU doesn't throttle but (as labeled by HWINFO 64) Core #0 still has a quite high temperature of 78-83 C, Core #1 is a bit lower at 75-80 C and Cores #2 and #3 are fine at 75 C and 70 C respectively. The CPU Package has a temp equal to the temp of Core #0 at all given times. Idle temps are around 40-45 C. The GPU is fine at a max temp of 75 C

Does this sound normal to you? In winter (ambient temperature of around 18 C - 21 C) my CPU used to max out at 75 C. I know that 18 C and 25 C are quite some way off from each other but can that difference really push my CPU out of the 70s C and into the 80s C?

As far as BIOS 303 goes, I haven't had any problems yet. I just have a feeling that the CPU fan could go louder than its current state.

UPDATE 2: I had left Hwinfo64 running in the background and I saw that it actually throttled. It shouldn't have throttled for long since I noticed no difference while playing but when I exited the game and checked out Hwinfo I saw that under the "Maximum" tab it said "Core #0 Thermal Throttling: Yes" and "Package/Ring Thermal Throttling: Yes"

Here's a list of all temperature values under the "Maximum" tab;
-Core #0: 87 C
-Core #1: 86 C
-Core #2: 82 C
-Core #3: 77 C

This happened at an ambience temperature of 25 C.

What are your thoughts on this?
Honestly, I don't know what's to blame here.
I really don't want to sacrifice performance and undervolt, so how about I set up a custom fan profile?
I've heard that ASUS prefers noise reduction over coolness thus their fan profiles don't take full advantage of the fans' capabilities.
I'll need guidance though. If you could recommend the best program for custom fan profiles and help me set the right values for the right temperatures I'd highly appreciate it.

UPDATE 3: Just set my A/C at 21 C. Same results....CPU still at 84 C. However now I'm a lot more certain that the fans could go a lot louder, they seem to be quite quiet. Especially when I close the game and the "Active Cooling" option kicks in I can hear my fans go louder and I can't help but think "why don't they go that loud when playing?".

UPDATE 4- FINAL: Like you saw on my previous posts I was getting really suspicious that something might be wrong with my fan speed. Turns out I was right.
I cooled my room down to 23 C and pressed fn+pgup to make my fans work at 100% speed. The results were outstanding. The maximum temperature my CPU reached was 74 C.....74!

Obviously now I need to create a custom fan profile because the default one isn't working out for me and that is where you guys come in.
I need help doing this. I would really appreciate it if you could tell me which one is the best program for that purpose and guide me to insert the correct fan speeds on the correct temperatures.

I just checked out his personal page and just to be sure, since I have a G752 model I should get the VOLTGROUND G752 config, correct?

I don't need or use this so I would send Dreamonic a PM or post to the thread I linked you too. Logically I would agree use the G752 config as I stated I don't really know for sure. For me the updated BIOS 303 has worked my ambient is 25.5c/78F my temps are great idling in the high 30c low 40c I don't game so I can't comment on those kind of load, Benchmarking on full CPU load I'm staying in the 70's C. I dropped from the Mid 40' to low 50' at the same Idle loads. This is working for my set up. I use All CPU Gadget and I just can't get over looking over there and seeing 36C to 38 C, I've never seen that on a notebook before my desktops yes with huge Heat sinks and 140m fans. So I'm running just under where my G75VW did. I have noticed since the 303 update my fan profile has changed with 1900 RPM being minimum and 3500 max. All the monitoring I have done so far the fans never go lower than 1900 RPM. Good Luck with your system Dreamonic seriously worked with this so I will defer to him.

It's high ambient so airflow forced onto/through your parts won't move "cool" air in as much as it will move "hot" air out. It can be surprisingly effective with enough airflow and enough heatsinks/rads.

Ok so I tried his G752 fan profile and although it didn't prevent all my cores from going over 80 C (max temp was 88 C), it did not cause them to overheat.
One thing I noticed though is that in the Notebook fan control program if I click "Enabled" it makes my fans work at 100%. Although the GPU doesn't need this, the CPU does so my question is;
If I set my fans to work at 100% before launching a game and then reverting them back to normal speeds, can that damage my fans? Given max time I play continuously= 2 hours and an average play time per day= 6 hours (it's summer so I got plenty of time).
Another question I have is, if I leave the custom fan profile to just do its thing, is 80-85 C going to damage my CPU short-term and how will it affect its long-term lifespan?

I really don't know how the same BIOS can work so well for someone but for another one work so badly.

EDIT: Nvm it just throttled again 😞

Could be you need a repaste? If you read more of Dreamonic post you find that the G752 can have issue with the way the copper contacts the CPU & GPU, he has found that at the time of repasting actually bending them a bit to get 100% equal contact. In other words your heat sink could be pressing on your CPU more on one side than the other this causes unequal cooling to each core? Its worthwhile to read his post he is really into G notebook book Modification for performance which of course includes cooling

I will read it.
What I noticed now that I gave it one more try is that if I set it to "Enable" (previously it was set to "Read-Only" and I don't think that enables the fan profile) and set my CPU fan speed to 100%, it will reach a maximum of 87 C (it spikes for a sec and then goes back down) but it will have an average temp of 70- 75 C and a minimum of 68 C.

I am really confused now by this though. I tried to equalize the temperature of my room to the temperature of my room in winter by using my A/C, which is around 21-23 C. In winter the CPU would not go over 75 C. How can the CPU in an environment with equal temperature and 100% fan speed spike to 87 C from time to time now, while before it would not go over 75 C without any custom fan profiles which means that the fan would probably not operate at 100%?

The only answer I can think of is that in winter I used to launch hwinfo64 and check my temps for just a second and then close it again. Now, I launch it and keep it running until I close the game.
Could it be that in winter the second I would check my CPU, it would be at 70-75 C but instead if I kept it running I would see that it would spike to 85 C again?
That's the only answer I can think of because there have been no hardware changes from then to now. The only change is the new BIOS but the custom fan profile overrides it.
As far as dust is concerned, this model is advertised with a built-in system to remove dust. Does it actually work?

What do you think? Can you shed some light?
