Hello everyone,
A bit of a noob question/inquiry...
When my (i7-6820HK) cpu is pushed hard, the fan responds and I can hear it kicking up... but I am concerned that only the LEFT side of the rear exhaust port blows out hot air. (When I mean the LEFT side, I mean when I am facing the laptop's monitor and my LEFT hand can feel the rear exhaust port pushing air out BUT the RIGHT exhaust port does hardly anything).

Why is the RIGHT side exhaust port barely blowing out anything? Is this normal?
From what I can gather.. the GPU is on the LEFT side and the CPU is on the RIGHT side... I assume that the RIGHT side should push out more air OR at least the same amount as the LEFT rear exhaust port.

By the way... lately when I play BF 1, the temps easy goes up to 75-85 degrees within 20 mins.
BUT months ago, for several weeks, when I first bought the game... it use to stay at a very comfortable 65-75 degrees for several hours consistantly.

My BIOS version is :
G752VS.306 with release date of 10/19/2016

I am also using the current version of ROG Gaming Center software app.

Thank you for anyone who could help me out.

The left fan is dedicated to cooling the GPU and the right one for the processor. The fans work independently to minimize noise. There are many factors contributing to the temp change, game updates, number of concurrent players online, driver, so on.

That's normal behaviour. But as I use a third-party fan control app for my G752VT, i leave one or both of them running at 12.5% speed. Most cases, it keeps it under 40c when I'm browsing or using a video editing software.

The other factor of higher temperature is ambient temp, like if your radiator is on or the weather is hot then it'll run at a higher temp. However I'm on the lower end i7-6700HQ, not the 6820HK and have made minor changes to voltages to keep the temps down even lower.

Thanks for the input. I am curious about this "under volting".. I've been reading a particular thread on this ROG forum about this. How did you go about undervolting your laptop? I've read that the ROG Gaming Center should be un-installed along with a clean windows 10 install as well. How much cooler has your CPU gone down? What software do you use?

Thanks again.

Holy cow bells!
I tried out the ThrottleStop with a -100v and my laptop now runs at a consistent 65 degrees when playing BF 1.. lol. BUT Im just on baseline settings for the graphics.
Way better than the 75-85 degrees previously.
Thanks for reminding about the undervolting.
