You probabaly want to keep that speedo in your 4wd though because in 4wd the fan is much more important and on the Nosram I think the fan is hardwired on a very short cable so can only be removed by chopping the wires.... no biggie but might invalidate any warranty.

It won't invalidate the warranty as such - but it will invoke a partial charge of around £15 should the speedo fail. If you are going to extend any wires make sure it's outside of the case; any direct soldering to the board (no matter how good it is) other than the solder tabs is a big no-no under the Nosram warranty.
