20/20 Air flow

[Manalishi]

Is it just me or is the air flow through a 20/20 backwards? On a 50/50 and a 2:90 the fan pulls air from the inside out then across the tubes sideways (I guess to say front to back) but on the 20/20 the fan is mounted in the middle/center of the unit and blows foward pulling tube heat inside the unit then out the front. So, 20/20 owners which way does your air flow? Thanks for any info.

The airflow in my 20/20 goes from front to back

 

[sir riff a lot]

same , front to back

I was always concerned there was not enough airflow tho so I installed a small fan and mounted it just behind the 20/20 in my rack , the heat gets blown out of the rack way better now.
