Laser cooling

The J48-1 I have can be air cooled, so this seems like the simplest option! The manual states that an airflow of 250cfm is required on both sides of the laser from two fans. This is quite a large air flow to achieve with two 120mm fans, do I have opted for four fans giving a total of about 450cfm. I'm also using a fan controller to regulate the fan speed from based on a temperature range of 35 to 55 degrees.
