I have a small to mid-size tower that I put 1 120 mm case fan and 1 140 mm case fan on the side panel. Now, my question is about the 140 mm case fan. Is it bad that the 140 mm case fan is blowing directly towards the CPU fan? It doesn't seem to be affecting the CPU fan because it is spinning on its own, but will it have an effect on the cooling process since they are basically just blowing the air to each other? If you need more info, please let me know!
