Case Fan Sizing
 

Okay, so stupid question... I'm upgrading the fans in my computer case and I have a spot for a large fan, but it measures in at 105mm... obviously not a standard size. I did a little looking online and there are people saying that if it measures 105mm from hole to hole horizontally, you're looking for a 120mm fan.

Incorrect advice or am I merely being daft?

+ 1 for noctua fans.

low noise and great ventilation. i upgraded from antec fans.

side question ...

is the D14 the best noctua cpu cooler there is? from what i understand, noctua's have the best noise/performance ratio

my i7-860 in a P180 runs at low 30's C idle at 50% fan from some zalman i got as a gift, 'cept it's blocking my ram slots so I wanted to swap it out.

i take it the P180 should accommodate any of the noctua's?
