Do any of the McLaren F1 variants have the fans?

I've been surfing the interwebs looking for information about the fan system in the F1. I came across the original press release for the car, which says what they do to the air. I've also found a small diagram that shows that the fans are in front of the front wheels.

However that's pretty much everything I've been able to find about them. Does anyone have the answer to my question in the title? Thanks in advance.

By the way, here's the link to the press release if anyone's interested: https://www.torque.com.sg/features/mclaren-f1-product-presentation-1992-aerodynamics/

I found this snippit online:

A complex three-part rear diffuser beneath the F1's tail incorporates a central single surface and two reflex shapes each side generate sufficient downforce to overcome the car's natural aerodynamic lift.

Simultaneously, two powerful electric fans remove boundary layer air from the rolled S-wave or 'reflex' diffuser sections, helping to control movement of the Centre of Pressure - the truly significant aerodynamic factor affecting vehicle stability and handling.

This photo of the diffuser shows what could be the fan inlet/outlet in the bottom righthand corner:
