I have:
Dell Optiplex 745
Old cpu: Pentium D 3.40
New cpu: Core 2 Quad Q6600 2.40 ghz
8 GB RAM
Windows 7 64
I did a lot of research before getting a new processor and found that the Q6600 works well with this 745 system, so went ahead and bought it. I installed it today and everything started up fine, Windows recognized the CPU and all seemed fine. I am using Antec Formula 6 as my thermal compound as it got good reviews and I watched a video on Youtube where someone used that on the same system.
However, I noticed that the fan wasnt working. When I first booted it up, it gave a spin and then stopped. I was able to boot up fine, but I notice the fan just keeps doing this. One blast at start up and then nada. HWMonitor does not show the fans in the screen.
It never shut down on me and aside from this problem, it never gave me any notice. Obviously, the fan not working scares me, so I shut down immediately and re-installed my old processor (the Pentium D) and also checked the fan connector on the MOBO and cleaned the fan as well. Upon reinstalling the old processor, Im having the same problem.
Im at a loss on what to do here.
Thanks
EDIT: I just noticed that my fan is spinning very fast, but its not making noise, nor is it showing up in HWMonitor. Im lost.
