After seeing the other topic I decided on starting my own as is a different system. Anyhow would the below graph be normal? After doing some research it seems as though the right side fan is running at full speed which is around 6003rpm though in the image its around 5900 something. I tried ramping up the cpu usage to try and get the left side to kick on but did not come on at all. Which leads me to suspect that it needs replacing. I was planning on fixing the screen bezel on this computer and adding possibly a 2nd harddrive. I've got the screen bezel already and the dual=drive caddy that replaces the optical drive. So at the moment just waiting for the 2 750gb hd's to arrive. Anyhow if the fan needs replacing I might as well get everything done while I've got the machine open so does it seem normal or should I replace that left fan? All throughout writing this post I've been checking the fans to see if the 2nd kicks on but only the left has been running the entire time at either 5998 or 6002 give or take so seem to me as though they should both be kicking on however I do not know.
