New cgminer that works in LTC only mode: http://cryptomining-blog.com/1262-download-cgminer-3-7-2-for-windows-scrypt-mining-on-gridseed-5-chip-gc3355-asics/
Shows local stats and HW. A step in the right direction. I don't think fan control will ever be an option, but here's hoping.
EDIT: Doesn't work

Had a pretty bad experience trying to get it to.
I did the port above, happy someone built a windows binary as I only run Linux myself. The fan is hardwired to the 12V power source, so sadly there's no chance of fan control. You would have to physically modify the device to do that (e.g. add a fan controller).
