Question Will a PSU be able to cool itself if the exhaust hole in the case is smaller than the exhuast on the PSU?

[Root602]

My computer, a Dell prebuilt has a custom form factor power supply. I bought a power supply with the same wattage and same dimensions but upon receiving it I noticed that the exhaust is 7cm large compared to the original PSU in my case that's 5cm. Will this make my PSU overheat or cause problems in the future?

It's "probably" OK.

But this is a one off configuration, with not many others to compare it to.
