Absolute Limits

(OP)
Apologies upfront is this is a basic question

But I was wondering, say you have a number of thermal parameters for on a forced convection heatsink, such as Dimensional Limits, Ambient Temp, Required Temp rise, heat power, heatsink total surface area, and air flow rate. Is there a simple quick calculation you can do to see if that surface aera is is sufficient to at that air flow rate to carry that amnount of heat away to keep the DT???

RE: Absolute Limits

(OP)
The reason I ask is someone is trying to tell me that its possible to keep a heat source thats 100 x 100mm at 400w cool to 30 degrees C with ambient of 23 degrees C with a maximum heatsink size of 300 x 300 x 80mm high with a air flowing through it of 0.06m^3/s

I personally dont see thats possible

This site https://www.cfdcalc.com/ does on-line CFD, but the process is a bit cumbersome.
