For those with cooling problems i found a way to control the both fans speed , and i think that auto fan speed never use the full potential of those fans , because i got even 94°C cpu temp and the fans sound aren't nearly close to the nousy sound when i set them to max speed.
You need to download rw everything from here http://rweverything.com/ and launch it , then select the "EC" tab that is circled in screenshot.

Wow. I thought most laptop now comes with locked BIOS so you can't do those undervolt stuff already. Good to know that software can be used
May I know what is your config for your Acer ? 4720HQ + gtx960m + 8gb ram + 1tb HDD ?
If your Acer is the old model, gtx860m + 4710HQ, your temperature is definitely too high. You're even in an air condition room. IIRC, in aircond room, your temperature will be <85 for gpu and cpu.
Do a benchmark. Do it for about 1 hours. See what temperature you get for your CPU and GPU. If it is stable it should be around 80-85 or even lesser.

P.S: You may consider other thermal paste like GC Extreme. I heard that it is better than IC Diamond.

Yea that's why I feel amaze lo. Cause what I know of is need to access BIOS features to tweak the settings. Well last time MSI Afterburner do have features to undervolt or overvolt your GPU. I think now still got.

I think they just get lemon unit. Other Acer user seems very quiet didn't complaint much. It is still the cheapest tho. haha

3D rendering require good CPU tho, if you're doing intense work, better get desktop or other CPU. I believe 4710HQ or 4720HQ can't handle intense 3D rendering well.

You can try Lenovo but then the screen is just, no. Asus has a similar laptop but theirs is single fan. Not a bad design choice because Asus has good thermals but a bit on the riskier side. I personally didn't go for Asus because of my friend's experience with the customer service. For Dell, you only have the Alienware sporting this graphic card. That i5 U processor might be a bottle neck to the GTX860M though and even when you buy that added box for desktop graphic cards, the processor is a surefire bottleneck for those as well. Their 'home' laptop I think uses  GTX850M but you get touch screen for the same price as GTX 860M 4GB variants of all the Lenovo, Acer and Asus laptops. I would suggest the Illegear Z5 but you live in Kuching. If there's a problem you have to go back to KL. But this is, in my opinion, the best laptop for GTX860M. You can customize to your heart's content and budget and as an added bonus, there's a keyboard shortcut for maximum fan speed if you're THAT worried. If it weren't for warranty and it's overall super flashy design, I would have gone for the Illegear myself.

The laptop is fine actually. Maybe the Cities: Skylines game is a bit too demanding. Sims 4, Heroes of Newerth, Sims 3, Microsoft Flight Simulator, SimCity and everything else runs perfectly fine (no throttling). When I limit my frame rate for Cities: Skylines it takes much much longer to throttle but throttling is still there

Since Kuching got service center, then can consider ILLEGEAR lo. Z5 is quite good actually. At least its cooling is a proven fact.

I recommend you it because it got better CUDA core and i7 quad core.. Well I got your point, maybe the resell value is not as high as Dell since not much people know of this brand.
Just make sure you got a i7 quad core or abv + min 8gb ram. Preferable 16gb if you're doing some intense high texture sh*t modeling. haha
I personally won't get laptop to do intense rendering job. It is a waste of money
