I currently can set four PWM pins to around 31 kHz with the following code:

void setup()
{
 TCCR1B = TCCR1B & B11111000 | B00000001; // Set PWM frequency for D9 & D10:
 pinMode(pwmPin9, OUTPUT); // Sets the pin as output
 pinMode(pwmPin10, OUTPUT); // Sets the pin as output
 TCCR2B = TCCR2B & B11111000 | B00000001; // Set PWM for D3 & D11
 pinMode(pwmPin3, OUTPUT); // Sets the pin as output
 pinMode(pwmPin11, OUTPUT); // Sets the pin as output
}

void setup()
{
 TCCR1B = TCCR1B & B11111000 | B00000001; // Set PWM frequency for D9 & D10:
 pinMode(pwmPin9, OUTPUT); // Sets the pin as output
 pinMode(pwmPin10, OUTPUT); // Sets the pin as output
 TCCR2B = TCCR2B & B11111000 | B00000001; // Set PWM for D3 & D11
 pinMode(pwmPin3, OUTPUT); // Sets the pin as output
 pinMode(pwmPin11, OUTPUT); // Sets the pin as output
}

I found this setup somewhere, but I don't know how I can set these four PWM pins to around 25 kHz instead. How is that possible?
