That fan will not solve anything; is a classic example of 'curing symptoms'. A computer must work just fine in a standard room with no chassis fan. One chassis fan - more than sufficient for any properly assembled comptuer - is installed so that the computer will also work in a room above 100 degrees.
The numbers: How many more CFMs does the 90 mm have compared to the 80 mm? 38 CFM into a thermal equation reports about a 2 degree temperature reduction. Your CPU in a 70 degree room must be so cool that when room temperatures increases 30 degrees, the CPU is still in a perfectly ideal temperature. If 2 degrees cooler solves anything, the actual problem remains unsolved.
Use heat (ie a hairdryer) to find the defective part. Heat is a diagnostic tool to locate hardware problems. Any part heated to hairdyer temperatures must work 100% normally.
Why do some install a 120 mm fan? To maintain the same airflow with less noise. Larger fans with the same CFM (more than sufficient for any computer) is a technique for reducing noise.
