Hi, I have a Predator Helios 300 ph315-52 and I had a technician replace my thermal paste and clean my fans. Temperature wise, my pc dropped around 15ºC when gaming, and 5ºC while idle, which seemed good. Before this, my laptop would idle at 52-53ºC, and now it's more around 46-49ºC. Depending on the game, high load went from 80-85ºC to 70ºC, which was really good.
However, my fans have started spinning way faster than before (higher rpm) for no reason. Before the laptop was cleaned, idle rpm was 1900 for CPU and a bit more for the GPU, at 53ºC. Now, when idle at 47ºC, the minimum rpm on the CPU fan is 2640, and GPU fan is 2940 rpm, which is a lot more noisy than before.
I tried updating BIOS, I tried updating nvidia drivers, I tried changing between Predator Sense versions to lower the speed, but it still constantly keeps going back to 2640rpm cpu and 2940rpm gpu when idle. I used to leave my laptop on during the night, now I can't deal with the noise at all. I used to swear by predator helios before and how it had great cooling for a laptop, but this has completely changed my views on this laptop because the noise while idle is unbearable, and the only software that can detect these fans (predator sense) doesn't allow you to reduce fan speed, only increase.
It seems to me that it used to consider 50ºC the "lowest temp" and would give it 1900 rpm on fans. But now because it got cleaned and reached lower temperatures (42-43º), it considers that the new "lowest temp" and assigns the 1900 rpm to it, and once the temp rises to 49-50, fan rpm rises too.
We tried finding solutions or a diagnostic, and we've read two different people say it's a battery related thing (one fixed it by letting the battery drain, and the other by disconnecting the battery for 5 minutes). While he was cleaning the laptop, he disconnected the battery. Could it have anything to do with this? At this point it seems so random it could be anything.
Has anyone fixed this issue or is this a lost cause?
