[CentOS] Need advice with a "hot running" graphics card

Hello all--

I have a old Radeon HD 2400 graphics card in my desktop connected by DVI 
to my monitor.

It may be my imagination but it seems that since upgrading to 6.8 
recently, after about 4 hours of use, my system seems to run "hot". I 
don't think its the man power until but maybe the graphics card? I found 
references to odd/high power consumption with radeons an particular 
kernel/radeon versions.

And, now I find this old post:

So 6.8 is 2.6.32-642.1.1.el6.i686

Has anyone else experienced this? Suggestions?
