I have an old W510 with Fan Error and when I power it up with

The fan in my T400 gave up and I got a replacement for like $5 on
aliexpress, I should have paid $8 and got the fan-heatsink asembly
as replacing the fan only was tricky, and my repair was imperfect.
looks like your one's a bit more expensive.

looks like your fan is $8 but the heatsink assembly is $33
I'd be tempted to try replacing just the fan, and if that fixes the the
problem but goes badly due to a fumble replace the whole thing.

The backlight in my T400 gave out shortly after the fan and I fumbled
the inverter card and blew out the controller on the main board so I
just use it as a stationary computer now.
