Update: Replaced the motherboard, and everything is working now. Or at least so it appears. The CPU fan however doesn't fit. I have it hooked up, and in front of the CPU. Will that be okay to do?
Well glad everything is working.
I see there is a prob;em with the fan.
I am not sure how you have it set up.
Sounds like you have the heatsink on yes? But the fan wlll not fit on properly but yo haveit hooked up and working in some fashion?
Really I would say you should get a fan which fits properly, if you have it hooked up what will happen is the fan will come on when it the cpu gets hot.
The question is will it provide enough cooling?
The strict answer is no because it is not installed properly.
However I guess you can do some sort of tests.
I mean you can watch the CPU usage and see if the fan stays on longer than normal it it
does then it would seem it is not providing enough cooling and you should stop whatever is using the CPU.
I would imagine the fan will get very loud as the temperature rises unchecked the noise alone will probably make you want to power off!!
You must have a good idea of how long and when the fan come on, that should be your guide but you really need a fan which fits properly, apart from anything else the noise wil be very annoying and you risk damaging your CPU. ( Don;t know it it has a built in over heat mechanism to shut down the PC or not - that would seem sensible, but you are taking a risk using it with a poorly fitting fan).
At the end of the day it's your PC and your CPU so it's your risk.
Personally I would be very careful with usage and get a fin which fit properly.
I would get this temperature monitor it should be very helpful.

Basically the fan is only blowing air but it should be blowing it down the fins.
If the fan is on high speed at low CPU usage I would be rathre worried to say the least - good luck!!
