Why does the cooler run for 2 seconds when turned on and off?

Question

Iron

I replaced the cooler on the Toshiba Portege R700 laptop, but it stops after 2 seconds of operation and does not turn on anymore. The old cooler works fine. What could be the problem?

Answer 1

Well, since it is with a new problem, then marriage is possible.
Perhaps the model of the new cooler is slightly different and it is not controlled by the BIOS in the same way as the native one.
If it does not turn on during the entire operation of the laptop and at high temperatures of the processor, too, then it’s definitely
either a marriage or the wrong cooler.

Answer 2

Good evening! Try running Aida64, see how the cooler behaves when the load increases and, as a result, the temperature, if the temperature rises above 75-80 C, and the cooler does not turn on, then you have to think.
