Ok so i'm suspecting my fan isn't working properly and so i tried hardware monitor and speedfan but both don't show my fan speed.

do you know which program might show it?

these are my pc specs:

intel core 2 quad cpu Q9000 @ 2 GHZ
4 gig ram
nvidea geforce GT 130m

I'd really appreciate if someone could help me with this.

I am assuming your referring to your CPU cooling fan's RPMs not displaying in speed fan.

In order for the RPMs to be monitored by programs such as Speed Fan, there has to be a RPM sensor built into the cooling fan.
The sensor's wire has to be connected to the motherboard. Cooling fans have either 3 or 4 wires, most have 3, that have to be connected to the motherboards CPU cooling fan power port on the motherboard. It is usually marked CPU_Fan.
The motherboard has to have this sensor reading ability built into the chip set in order for it to work.
The operating system also plays a part in whether this feature works or not, older operating systems such as Windows 95 through Windows
ME may not display all options available in Speed fan.

Either your cooling fan sensor is defective, or it is not connected to the correct CPU_Fan power port on the motherboard.

thank you for your reply Bruce,

yes i meant my cpu fan's RPMs

decided to take my laptop to the store for some cleaning & to check if my fan still works properly.

and why i think it's not working properly: my pc goes up to high temperatures very easily.

i hope nothing is wrong because i got exams coming and due to schools poor choice of placing the exams (right after 1-2 week vacations) there's literally no time for my laptop to break down. Luckily i could get my store to finish my pc in one day although it'll cost me a bit more

I was not aware you were talking about a laptop computer. :whistle:

My post above was more geared to a desktop computer, had I known we were talking about a laptop, my post above would have been worded a little bit differently.

Please let us know the outcome.

Thank you for replying back and letting us know what the problem was.

I know your initial issue was the programs you were using were not displaying your CPU cooling fan RPMs.

I am not sure if you resolved that issue or not, but as I said earlier, there has to be a sensor circuit built into the motherboard which monitors the output from the cooling fans RPM sensor.

Any way, good luck and hope you have a happy and safe new year.

Bruce.

the initial issue isn't a problem anymore since i thought my laptop got this hot because of the fan not working well

so no need to get the speed of the fan now since it's working properly (had that checked)
