Acer V15 Nitro Overheating 95 Celsius

Hello all,

I have an Acer Aspire V15 Nitro VN7-592G running an Intel Core i7-6700HQ processor.

I was converting a video on HandBrake, and noticed a CPU core temperature of 95 degrees Celsius on ThrottleStop.

Alerted by the high core temperature, I opened the window, and allowed the cold, Canadian winter air at a temperature of 3 Celsius flow through the fans, and hopefully cool down the processor. When I held the PC against the window, there was no decrease in temperature. The temperature was still hovering within the range of 95-98 Celsius, even though the air being exhausted from both condensors felt cold.

I clean the condensor fins on a regular basis, and have Acer DustDefender enabled at all times.

Could the high temperatures be caused by defective thermal compound?

For the record, my old Sony Vaio F series had a 45 watt Core i7 processor, and it never got hotter than 80 Celsius on maximum load.

I have attached a screenshot of the CPU temperature while the CPU was working at its maximum capacity, with the PC being held outside the window.

Thanks! Acer VN7-592G CPU Temperature.jpg

You could try reducing the maximum processor state to 80% or similar and see whether temperature drops, yes repasting CPU also a very good idea.

I did just that in the Windows Power Control, but it seems to have no effect on the maximum state of the CPU. The CPU still revs up to 100% usage at 3.3 gHz initially, and once the Bios realizes it's getting too hot, it throttles it down to 3 gHz.

I would consider repasting the CPU with some Arctic Cooling MX2, or some ThermalTake compound I had laying around. I am not exactly sure on how to dismantly the machine. An helpful tutorials out there please? Thanks

Hi,

Sorry, I couldn't find any disassembly videos for your model but found few similar models on youtube, you have to watch them and identify the corresponding connections and work out the disassembly of your laptop.

Hi,

Repasting will definetely help, but don't have high expectations.

The main reason for these temperatures is the way how acer implemented the cooling on these notebooks. The fans will never run at 100% unless you use a custom fan control software. And it's true at 100% they are loud, as a jet engine.

I have the older 591G with the 47W I7 and after repasting, I got the same temperatures (92-95C) but the core frequency went up from 2.6 to 3.1 Ghz on CPU core.

If I use notebook fan control to max out the fan speed I get around 86 degrees and 3.4 Ghz on the core frequency (max core frequency when all 4 cores are active, they cannot go higher). However, if I stress test the dGPU in the same time with the CPU I get max temps (92-95c) and the core frequency at around 3 Ghz

In my opinion the notebooks cannot handle cooling at around 80 degrees if you max out the CPU and GPU even at 100% fan speed.

But the CPU and GPU can handle these temperatures and they have built in protection (which partially you deactivate with throttle stop) to avoid damaging these components.

There are plenty of discussions on the forum about this issue, just look around. And of course different results.

Unfortunately notebook fan control (https://github.com/hirschmann/nbfc ) does not have any configuration for the 592G

If it's a dual fan model like my VN7-591G-56JG, you could try my profile for fancontrol. Works a treat on mine.

Battlefield 1 runs around 40-60 fps with the 860m overclockd and the CPU maxxed out and it's around 90 degrees without any throttling.

Edit: I repasted my CPU and GPU. the acer stuff was complete mess and not even on the chips, just all round it.
