80mm VS. 120mm + adapter

[GamE]

My case has a free 80 mm slot for an extra casefan (Already have 2), and I was wondering if it would be beneficial to use an adapter to install a 120mm fan into the 80mm slot, assuming it fits..

Could anyone help me out?

It could, but because of the larger dead center of the 120 it might be slight.

I had a shuttle with a 92mm high rpm output fan (note the system fan is also the cpu fan on a shuttle), it was noisy (actually very similar to a hair dryer noisy), ran 5500 rpm and only cooled 53C under full load.

I put on low rpm high output 120mm fan and adapter. it was much quieter, only turning 1800 rpm and moved LOT more air and cooled 44C under full load.

I guess, it would really depend on the fan and the location as to how well it does. but just from my experiance, the 120 will move just as much air if not more and be much quieter than a 80

I suppose I should get a 120mm fan then.. The worst that could happen is that it moves the same amount of air
