GMPP fan control is simple on/off if I remember right. That could generate some big current spikes so maybe it would help to move the GMPP fuse block to the battery to help buffer those spikes. If you lose another alternator I would consider a better method of fan control. Even a simple two speed controller can reduce the current spikes and average fan current.
This kit adds two speed fan control to the GMPP fuse box. A great upgrade imho.

I am assuming you have dual fans which are needed to use the above kit.
