I did look at that, but the only way I could still see the setup LED's (which are currently on the left hand side of the speedo) would be if the wires were on the left of the speedo. This meant that both the power wires were in the way of the fan, and they would not go under the shell, since they would have to bend over the top of the already warm heatsink. So far I have not had any problems with heat, and I have not even put any vent holes in the raised part of the shell to release heat.
Don't forget that the LRP and Nosram speedo's ran fine without fans, as did all our old brushed speedo's!!
