Dell Latitude E7450 CPU fan not working
Hello everyone:
i have a problem with my Latitude E7450 CPU fan, it seems to be working fine, up until one day i spilled some coffee on the keyboard, then i had to disassemble it then i cleaned the keyboard, and have reassembled it.
from that point the CPU fan no longer works when i am using the operating system at all......
i have checked some solution in the internet they suggested to apply the latest BIOS update which i did, but unfortunately the problem persists.
what bothers me the most that the fan works fine when i launch the Dell diagnostics, but it stops working when i load my windows 8.1.
my CPU temperature according to CPUID HWMonitor is : 59° for the package, and 59° for Core 0 and 58° for core 1
i would really appreciate it if someone would guide me to solve this problem.....
thanks in advance

@norman.fusata
Yes the fan should turn on when it hits a predefined temperature.
It should spin-up at that temp and then spin down when it goes below that temp.
That is a sign of a normally working fan.
And again your temps are very good, better than most!!!

Hi norman.fusata,
Update the BIOS and Chipset drivers from the given link https://www.dell.com/support/home/us/en/19/product-support/product/latitude-e7450-ultrabook/drivers
If this doesnt help PM us the service tag details we will check the warranty to assist you further.

thanks for your replay:
before the spill it was around 50, 55 the most, it rarely goes beyond that...
do you think that it only starts spinning when it hits a point when its considered Hot for the CPU? it really got me confused.....
thanks again.....

thanks for taking time to replay to my issue:
about installing the latest BIOS update it's already done, but i will give it a try for the CHiPSET drivers.
About the warranty, it's already been voided, since my laptop is used and not new...
best regards

Thanks for the replay:
it really concerns me, because before it was spinning from time to time, now its not spinning for almost 5 days now, but it does when i run Dell diagnostics, maybe because of the cold weather? i am not sure, i will try loading a stressful program for the CPU and see what happens

following my little brothers suggestions, i installed a game called Mincraft, according to him its very stressful for the CPU, and after installing it and loading it for 2 minutes and Voilà, the fan is super spinning.....
thank you for guiding me to finding the answer.... i really appreciate it.
best regards......
