Why does the laptop cooler stop rotating after changing the CPU?

I have a Medion Akoya E7222 laptop, which has an i3 2370m installed as standard.

But since this was a bit chess and in Dekstop operation was often at 80% load and I still had an i5 3210m lying around, I converted the processor, of course I paid attention to the TDP, both CPUs have a TDP of 35W so it should be from the Cooling won't be a problem.

But when I use the laptop with i5, the fan does not turn and the temperature often rises to 60 ° after a short time. When I use the i3, the fan turns on and cools the CPU when the limit of 45-50 ° is exceeded.

But I don't quite understand why the fan is stopping, although the rest of the system has no problem with the i5, BIOS works, Windows works, only the fan doesn't work.

Finally rest, what more do you want.

Oh right now the fan turns on and cools, but not loud, but still a miracle that it works again.

But still strange why it only cools the i5 down to 60 °, you can change it to cool earlier

60 degrees is perfectly okay. If all goes well, you can be happy. You should only look when it gets 90 degrees or hotter. Maybe you forgot to plug in the fan connector.

Or your UEFI / BIOS is purposely not turning the fan on.

Ok yes, I know it from desktop PC's. 60 ° is not quite ok, but in the BIOS I can't set anything via the fan and with notebook fancontrol I can't set the fan either

Up to which temp did you run your system?

Let the CPU run up to 75 ° - 80 °.

The 3210m has a different temp curve than the 2370m.

The thing about the blocked fan control means that you could otherwise destroy the CPU, or (more likely) the system could crash.
You can run a stress test with CPU-Z and see whether the fan works.
Incidentally, 60 degrees Celsius is also okay with desktop PCs (if you do something about it).

Ok, I didn't let the laptop run more than 60-70 ° because I was afraid that something would happen.

But can you still change the temp curve?

Relax, it will spin 100%

let him run a little for 15-30 minutes.

have fun

Try Fan Control and Notebook Control

The CPUs can turn 90 degrees and more.

In addition, the 3xxx is always warmer than the 2xxx series.

60 is great.

It gives me a miracle that your book accepted the i5-3210m (22 nm) so without a previous BIOS update at all. Medion will probably have had a mainboard preconfigured for "compatibility" developed for this notebook series from the start.

According to Intel, the i3-2370m (32 nm) can only reach a T_Junction of up to 85 degrees (PGA 988 version), while the i5 - 3210m (22 nm) can go up to 105 degrees.

I therefore see no reason for action on your part to want or have to change something. That should be so.

My book with i5-4310m (22 nm / 100 ° C) only starts at about 60 degrees with active ventilation. Only with this book you don't hear that when the fan speed is low, you only feel it at the air outlet. 😉
