I need a new 92mm square, computer fan. These are easy to find in 25mm depth. However, the one it is replacing is only 20mm and so a 25mm deep one won’t fit in the casing…

Any suggestions where I may find a skinny fan?

They have other options. First hit for “92mm low profile fan”.

Googling “92x92x20” throws up a few options – seem to be outside UK though

That overclockrs fan looks promising, but it’s a 4pin connector – I only have a +&- connection available.

The 4 pin connector is for speed control iirc. Connect the red to red and black to black and it’ll run flat out. Pretty sure you can by a conversion jump lead if required.
