I also live in Asia (Vietnam) and my previous two laptops have had Intel chips (current: MSI GE66 i7+3070, previously an old Clevo with a 970m). I've never had noticeable thermal throttling even when running in very hot summers in rooms with barely functioning AC (which is basically every room here). My northern European body struggles - a lot - but I haven't seen my laptops being much bothered. I do a lot of intense 3d work, I would notice if it started throttling. Maybe the problem was your laptop?

Are your tasks CPU-intensive though?

My laptop idles at less than 20°C above ambient, so usually in the high 40s, but the fans already speed up when it reaches 60°C - at 37°C I have just a few degrees of wiggle room until inevitably it starts cooling more aggressively.

Yes, I used to do a lot of rendering on the CPU. Fortunately GPU rendering is better now.
