Fan issue (90B) and possible overheating

[St3ve1]

Hi,

For a week now i got an error when turning on the laptop, that was "a system fan is not working properly (90B)....."

Now the unit was still booting however i have noticed that when playing games, the casing started becoming really hot.

Since then i have tried a CMOS reset and BIOS recovery.

During the BIOS recovery the fans started spinning really fast and after a restart the system message didn't appear anymore, they keyboard light also disappear and it didn't come up upon pressing the F5 button.

I did update the BIOS again from the HP support site, the backlight was working again and no system fan errors.

My query is ? how do i know if the fans are spinning properly or not ?

I have noticed that the FPS have dropped a bit since the fan issue and also i ran a Furmark test and i got the following data:
FPS: 14
GPU: temperature: 75 C

Now i know i shouldn't expect high FPS from a GTX 965M because its a mobile chip but how do i know for sure if the fans are spinning properly and if the GPU is working at proper frequencies?

When playing games the fan doesn't seem to spin as fast as it did before and also there is an FPS drop like from 72FPS i had in Dungeon defender to 57, that could still be the graphics settings being reset but its just a little concerning.

Kind regards,

Steven

Hi Steven,

In some cases it can be the Bios creating the problem the error you received. However if it the casing still feels real hot to you you should have the PC checked out.

You could start by performing a cleaning through the in and out air vents of the laptop using compressed air (cans available at local electronics store) when the computer is off and cold.

You can also perform a stress test with programs (free trial) such as AIDA64 extreme to get an idea of temperature and fan speeds.

The max temp for your CPU and GPU is 100°C (so 74°C is in the norm for laptop) and throttling should start about 5-10 degrees below that. Anyway there will be built in security which will switch the PC off if thermal damage is iminent.

If problems arrise you can always get the fan replaced quite easely without too much cost.

Hope it helps,

David

Thank you for the reply. 

Indeed the PC seems tu run stable, and it is throttling so temperature sensors are also alright. The fans seem to be spinning and the FPS drops could also be because the GeforceExperience, i should consider downloading the driver from the HP site and sticking to that i think. The AIDA64 is just what i was looking for, i knew there were benchmarking tools but was unsure about the one that would give me more testing options.

I will consider cleaning with some compressed air, the laptop is almost a year old now.

Thanks again and all the best!
