Failed fan

[ChrisSP1]

Upon boot-up I get a warning sign after the box sounds as though it has revved up, saying that there is a fan fault, and will close down. There is an option (which quickly disappears) to keep going if you hit 'return'. That seems to work. Being cautious and very inexperienced, I replaced the main fan next to the rear grill and thoroughly cleaned out the box, only to find that there are three fans, and a slightly different message - it seems that it is CPU fan 90B.

Does anyone know a part number/cost/source for this, please?!

This is for information only,  the fan can be removed (4) screws.

CPU fan  is a PWM 4 pin type. Likely 80mm, but here is how to measure.

  IF IT IS an 80mm, You want a fan with 800-2500 RPM
