I have recently bought a used laptop (Acer v15 nitro i7 7700hq gtx 1060) (over 2 years old therefore no warranty). Performance super, only battery life a little short. So I wanted the cpu and gp undervolt synonymous because of the temperatures, which were not insanely high but not really low (I have no values unfortunately).
I have the laptop now exactly one week in operation.
I've undervolted the cpu by -140mv, and also get stable results of 72 ° in cinebench and in the xtu stress test.
But as soon as something affects the gpu (gaming, benchmarks) the temperatures climb. So far, that the cpu partly rises above 90 and the gpu always stays in the higher 80s, even if the cpu itself is only 40% busy.
Gpu is also undervolted, but not very strong.
Before that, these issues were not so much with gsming, now all of a sudden I can't play anymore because I'm afraid of breaking my hardware due to the temperatures.
Does anyone know why that is? Could windows bring something new?
Setting back undervolt makes the temperatures even worse.
Since it is a notebook, it could be the fans. Is the device unusually loud or even quiet?
Do the fans run normally or do they rattle?
It can also be an anasmmlung of dust and hair on the fins of the heat sink and thus disturb the flow of air, thereby you get a heat accumulation in the device.
Fan possibly defective? If the ventilation can't turn up properly, it quickly gets tight in a notebook.
I do not think that the fans are quite loud, especially when Acer Coolboost is activated.
The fans are quite loud, but this is also included in reviews of new equipment. They run through normally, no rattling or the like.
The dust accumulation I think also unlikely, since the rise in temperatures happened so suddenly (within a few days)
That can happen very fast. If the ventilation absorbs a few hairs, it may already have been.
Since it was previously without any problems, I'm almost from a contamination or a defect of the fan.
I have - even if it is a bit tedious - such problems (with multiple laptop models) always with cleaning the 'inner and outer airways' can fix.
