I'm looking to replace my CPU fan in my computer. For some reason it's wearing out the bearing and I need a new one before it dies. I see that the fan on the heatsink is a 70mm fan. I'm unsure whether that means I need a fan that is at most 70mm or it's completely irrelevant. There aren't that many 70mm fans out there, and some pretty good ones I like are 80mm and 92mm, can I fit them in my computer?
(My case is a Thermaltake Versa II and my MB a MSI 760GM-P34 (FX))
