Macbook pro mid 2010 Fan too slow

[mas53]

macbook pro 13 inch mid2010
OS High Sierra
SMC version 1.62f7
Boot ROM version 68.0.0.0.0

problem: blower run too slowly and after boot in a couple of minutes the computer shootdown;
I installed a fan control application that partially solved, the blower follows the the RPM set and all the temperatures displayed are reasonable.
The problem is that during the boot time the blower run at minimum: 2000 RPM, as I read as soon as I open the fan control application.
In order to run the complete hardware test (no problem found) I had to install a second blower with external supply.

Is there any way to reinstall the SMC ?
Is it correct the EFI version?

can anybody help me?
thanks in advance

Might need to apply new thermal paste. (I assume you cleaned the fan and vent.)

Reinstalling the SMC is tricky. Here's a post about it, which I can't vouch for:

Reinstalling SMC and EFI

The only way you can "Re-Flash" manually your EFI frimware is by extracting the EFI Update file, then flash that extracted file by booting the Mac into "EFI shell". (That extracted file could be a .scap file or .bin file, you'll have to google that to find out which one is the actual file that...

Try resetting your SMC before taking more drastic measures.

Shut down your Mac and make sure the power adapter is plugged in. On the left side of the keyboard, press and hold the following keys: Shift, Control, and Option. While holding these keys, use your free hand to press and release the Power button. This should reset your SMC. If you need more info, go here: https://support.apple.com/en-us/HT201295

FYI: I have a 2011 15" MBP that has had some thermal issues due to a bad GPU, in addition to a battery that is long overdue to be swapped out. Anyway, I've been using SMC Fan Control to manually set the fans at a minimum of 6000rpm to increase airflow. Boot time from my SSD takes only seconds. Combine that with auto login and the fans ramp up very quickly.

If I were you, I'd pull the bottom case off and spray some compressed air in there. Your 13" only has one fan. Considering the age of the machine, there's likely a lot of dust bunnies built up that could be significantly blocking the exhaust.
