I doubt you’ll find an answer to the fan question. First you need to specify a fan.
What engine, then which fan because an FL 60 is mighty different than say a new Cascadia. Then the engine could be from 5.9 liter to series 60 to cat engines…

Then even when you have a part number- very very few fans ever listed their outlut capacity in literature (or computer).

Will hit the nail on the head here!

if your having a cooling issue and the fan doesn't seem to pull air like it should, first thing to check is the supply air pressure to the fan clutch. there is a valve with a electronic solenoid controlling the fan clutch. it could be going bad. also the friction disks in the fan clutch could be worn out and slipping. most fan clutches are rebuild-able but you sometimes need special tools to get them apart. it's also a dangerous game to play if you don't know what your doing pulling one apart on the bench. there is a heavy spring under pressure inside that when let loose can take a couple fingers off with it if not careful.

On checking air pressures, plumb in a gauge with a TEE into the fan clutch and energize the fan with switch in the cab. No switch, start up the engine and let the dryer pop off then shut off the engine. after turning off the engine within a few seconds the solenoid should release sending full air pressure to the clutch. the solenoid is a normally open type meaning when there is no power applied to the solenoid, it should allow air to pass through. Read the gauge in the dash in your primary tank and the gauge you installed should be reading the same.

I did find an answer. I called the 800 number for freightliner tec support. Took a bit, but got the answer. 12000 cfm to 20000 cfm. Topside 1900 rpm.
