My geometry skills are failing me or I'd be able to tell you the actual size. But no it's not you just need to measure across (not diagonal), one corner to another adjacent. Likely 120mm.SO my fan thats inside the top part of my PC went out. It's a 190.5mm size corner to corner fan that glows blue. I want another of the same but I can not find one at all... Is 190.5 the right size I should be looking for?
edit: my own bad math. 97.6mm...I'm going to assume a slightly off measurement and saw 100mm fan.My geometry skills are failing me or I'd be able to tell you the actual size. But no it's not you just need to measure across (not diagonal), one corner to another adjacent. Likely 120mm.
