Power Supply bigger than fan cutout?

I recently replaced my old power supply for a tx750M. Before I opened the box, i checked the case to see if it would fit as it is 160mm deep. It appear to fit lengthwise as the PSU mount is adjustable.

The main problem is that the PSU fan cutout on my case (Thermaltake commander MS-I Snow Edition) is only 120mm, while my psu fan is 140mm. If I install it, not all of the fan will be able to obtain air.

Should I still install it, or should I put the fan upright instead? If I place it upright I would probably install another fan in my case to ensure it stays extra cool.


If anybody needs a picture to understand, I can post one.

I would prefer a picture, anyways I have run my Antec power supply for a few years with half of the power supply fan blocked. Despite that it ran strong for a few years, I believe power supplies can take a bit of a beating temperature wise. The more quality your power supply the more of a beating it can take.
