Hello everyone, this is the first time I write in support apple. I'm an Apple user for many years and working in the world of computing.
I am a specialist in repairs Hardware and Software on Laptops and PC.

Personally, I use a Mac Mini A1176 mid-2007 CPU with 1.83 ghz intel core 2 duo.

A few days ago while the Mac is off, and also holds on to the CPU fan is at 8000 rpm.

I tried to reset the SMC but the problem persists.

I disassembled the mac and I replaced the fan with another purchased from a dealer, but the problem persists.

My mac has the version of Boot ROM Version MM21.009A.B00 and SMC 1.19f2.

you can have a firmware reset CD for this model?

I also made diagnostic tests and I was presented the following error:

4MOT/1/40000003 Masters - 8363

What can I do? Have you ever?

thanks
