Would this fan work on asus k31bf. fan really noisy and rattling of late. would i need 3 pin or 4pin if it does fit?

Hi, We are not so sure it will fit into your case, assuming it uses the usual 120mm or 140mm fitting, it should be ok. This cooler requires a 4 pin connection. Hope this helps Thanks, Ebuyer Team

What dimension are the fixing hole centres?

Mounting hole spacing: 71,5x71,5 mm

Does this fan have a flow direction arrow on the case?

Yeah, all fans are the same. They all spin counter clockwise and open side is intake.

I have a Dell Optiplex 9010 with a 5 pin fan, can I use a 5 pin to 4 pin adapter with this fan?

Noctua 12V fans comply with the established specifications for standard PC systems issued by Intel and AMD. Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often deviate from these specifications e.g. by using proprietary fan headers, custom pin-alignments or pin-configurations, different methods of fan speed control, etc. This can lead to compatibility issues when using Noctua fans in systems from said brands. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues (e.g. errors or shutdowns due to low fan speed) can often not be resolved. As a result, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.
