Need help with exhaust fan size.

[rns1016]

I have a Compaq Presario S4210NX. And I'm trying to find out what size the rear exhaust fan is.

Get a ruler out and measure one of the sides. Use centimeters. The size you measure will equal the size of the fan. Most of the times it's either a 80mm (8cm), 92mm (9.2cm), or 120mm (12cm).

take a picture of the fan and we will be able to tell.

or measure it as Joga said.
