You need to get lm_sensors too. Gkrellm gets the info from lm_sensors. You can get it here:

It's not to bad of a install. I think you have to run sensor detect when you get it installed. It is command line. No GUI, sorry. It has a good how to though. There is also a rpm but I can't find it. I think it may be on the CD. If it is it has a bug. Let me know when you get it installed and I'll find out what to change.
later guys
