I have bought a Talismoon whisper fan, after startup a lightning at the fan and rrod.
Opened the Xbox and nothing to see, only a bad smell Put the original fan back and tried again. Xbox is running but no fans turning.
Removed the mainboard and discovered that the Q3M1 transistor is broken, there is a hole in the middle.
I found out that my Falcon has only one transistor and that the older Xenon / Zephyr have 2 of them, these are the BCP51 of ZT751 transistors that i can find.
I cannot find if the transistors for the Falcon are the same as for the other ones.
I thinK RDC should give us some light on this. My geuss is that you got a short during the installation, not necessarily from the talissmoon. I have installed plenty of those and none came back with any issue.
