Hello guys
I'm simulating an CPU cooling with heat sink in fluent
My inlet condition was determined by considering fan blow. (Which means that i assumed to skip fan conditions) Instead of fan setting, I gave B.C at inlet with maximum velocity from fan's volume flow rate.
And then I solved with standard k-e with Enhanced wall fcn + Energy Equation.

The problem is that pressure at inlet is "lower" than outlet.
But my velocity vectors seems correct (they head from inlet to outlet)
So what is problem?
Should I simulate my case with fan..?

Any helps will be thankful!!
