Thank you Maestro for the suggestion. With Temp Mon or Hardware Mon I can only pick up the SMART sensor of my 2 Raptors inside the case. So I have my HD temp done via software. The problem is that since I run a GigDesign Accel card (1.4Ghz), it does strip me out of the usual CPU temp mon that I had with the stock G4-400. That is why I would like to be able to monitor the CPU temp and the ambient temp in the case to make sure it is not too hot.

It looks like the little 3.25'' controlloer whitlock is refering will be perfect for the job! (and cheap).

I will post some pics once I get all of that setup.
