Install top fan right above power supply??

Hello, I am in the process of building my rig and have a question related to using the top mount case fan. I purchased the Thermaltake Armor Series VA8000BWS case and a SILVERSTONE SST-ST75ZF PSU. The fan for this PSU is installed in the back. Since this PSU is very large the case top mount fan would be sitting right above the PSU fan. I was worried the case fan could create a vacuum in that area preventing the PSU from getting enough airflow.

Should I use the top mount case fan in this scenario??

Thank you in advance.
