Glycerine (and methyl alcohol) were the standard anti-freeze components before the advent of ethylene glycol solutions and in every respect the ethylene glycol was a significant improvement; I'd never use glycerine when a modern anti-freeze was available.

Of course if you don't need an anti-freeze, plain water has better heat transfer properties. You might try using one of the "water wetter" additives to help heat transfer but I think, as stated in another post, your cooling system is sub-standard.
