I've been using Gkrellm for Windows recently and in linux for a
long time.
It has some of the things I like (CPU, disk, network graphing) but missing some of the things
I want (fan speed, temperature and whatever). Does anyone know of a full-featured FREE
Windows utility comparable to gkrellm?

I use and like iobit. It has a performance monitor included with it.

Thanks Xoth, I'll look at this one a little closer.
