Hi famouzr,

I have a GL553VD too and also had heat and thermal throttling issues since i first bought it a year ago. Setting max CPU usage to 99% in power options does help abit since iirc it disables Intel turbo boost for your CPU.

I have tried underclocking my CPU and GPU, but to no avail, the temp does take more time to heat up when underclocked compared to normal clocks, but it does eventually reaches the same 81~88 C. I think it may be due to ventilation problems so this month im planning to open up my laptop and see if theres alot of dust or something inside, and to check thermal pastes etc.

At first I thought that it may be because of our model build that is causing the heat but my friend who also has the same model only reaches to about 75~83 C during heavy gameplay.

Maybe you should consider cleaning your laptop up or if you are not confident in doing so, try contacting support. Good luck 🙂

EDIT : Also, i found that thermal throttling only happens when your CPU/GPU reaches 85 C, As long as it doesnt reach 90 C, most people would say its normal but less heat = better is true.

Hello,

I was thinking it was drivers but I noticed lags start when CPU/GPU temperatures are higher then 80. Is it normal for such a laptop or should I give it back to the support or maybe can I fix it by myself. Laptop is 10month old

Yep, it's normal for this laptops' cooling solution, and even not critical at all. Critical is 90+°C.
Out of box I got 80-85°C with peak value 88(89)°C and 78°C on GPU. As I get it, it's impossible to reach lower temps with such cooling system. To achieve stable 70°C on CPU/GPU I was made to disable Turbo Boost an set FanBoost at max 5200 RPM.
By the way, with 99% processor state you miss 100 Mhz CPU frequency. To get full nominal 2,5 Ghz call register editor (Win+R → regedit), go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7 and in Attributes graph set "Attributes"=dword:00000002. Then in power plan options "Processor performance boost mode" will appear. Select "Disable".
Full list of modes:
dword:00000000 - Disabled - Don't select target frequencies above maximum frequency.
dword:00000001 - Enabled - Select target frequencies above maximum frequency.
dword:00000002 - Aggressive - Always select the highest possible target frequency.
dword:00000003 - Efficient enabled - Select target frequencies above maximum frequency if hardware supports doing so efficiently.
dword:00000004 - Efficient aggressive - Always select the highest possible target frequency if hardware supports doing so efficiently.

However, what I noticed (with HWInfo64) that with TurboBoost activated CPU cores start to throttle when one reaches already 80°C, but I noticed no FPS drops or lags during throttling even while 3-5h gaming session. If I get it right CPU throttles to prevent reaching high temps, not to cool down those it already reached. I never noticed temps reach 90°C on peak even while playing in summer. So, I thinks, lags are not because of thermal throttling. And with such temps there must not be thermal shutdown: latter occurs only when CPU temps reach 100°C or GPU reach 95°C.

Also, I got now 303 hotfix BIOS (GL553VD.303, 28.04.2017) and last win 10 update, and I have had no BSODs' for near a year I use my laptop (MATLAB/games).

Did I get you right your friend also has GL553VD and he got 75°C average/83°C max?

P.S.: however it seems that it's impossible to reach lower temps with 1 fan/2heatsinks, I wonder if there will be some ventilation improvement if one removes DVD-ROM. What do you think?
