New (and working) laptop cooling fan not working. What to do?

Question

Cooling systems

Good afternoon. I really look forward to help, because. I didn't find anything on the Internet. My story. In my laptop (hp-g62b26er), several blades are broken on the cooling fan (I can’t glue the broken ones - I lost them) because of which the laptop makes noise under load. Finally decided to buy a new fan. I put it. But when you start the laptop on the monitor, the inscription is error fan 90b (problems with the cooler), the fan itself does not spin, but sometimes twitches. The fan is working, I checked by connecting the fan just by wire via usb. Here is a photo of the fan I bought - https://89.img.avito.st/image/1/9NfnXrayWD7R6dozgz... . And by the way, I can’t just remove the coil with blades from the new fan and put it on the old fan with broken blades - they are different, the coil (if I put it correctly) should not be installed.

Answer 1

The board is probably supplying low voltage to run the fan at low speed. And the new is not enough to start. Or the current protection is triggered on the board (the new one has 0.5A versus 0.45A for the old one).
Try to buy the same model that was in the original:

Of course, in extreme cases, the collective farm method remains: cut off the red wire from the new one and solder it to USB power, but then the fan will always run at top speed.
