Question 1

what adapter do i need to connect these to my power supply? and can i connect all on the single cable

Accepted Answer

I purchased the 140 mm, though I would assume they should be the same. the fans themselves are 3 pin if you are going to attach them directly to your motherboard but they also come with 3 pin to molex adapters (which I used) in order to connect them directly to the power supply. I was able to attach two fans in series to one of my power supplies molex strips.

Question 4

Is the 92mm size a measure of the physical plastic, so that it's 90mm from screw to screw?

Accepted Answer

The size is the actual outside measurements of the housing. A 92mm fan has holes on 82.5mm centers and a 120 mm fan has holes on 105mm centers. I have a Thermaltake case with room for a 120mm fan, but the widest holes are on around 93mm centers that don't fit any readily available fan that I have found except these. My 120mm version of these has a second set of holes on the output side on about 93mm centers that work in this case. I stocked up while they are available.
