Do you mind posting the command you started cgminer with?

Take all the extra parameters out of your command line and let cgminer use the default settings: `cgminer –-scrypt -o http://netcodepool.org:8337 -u usernmae -p mypass`

If you using a Nvidia card you should use cudaMiner since you will get better hash rates for it. <https://bitcointalk.org/index.php?topic=167229.0>

What kind of graphics card do you have? Check out the bitcointalk forum post about this (<https://bitcointalk.org/index.php?topic=171515.0>)

Basically, ["The auto gpu and fan settings are only for ATI cards I believe."](https://bitcointalk.org/index.php?topic=171515.msg1971560#msg1971560) If you have a different one, perhaps change your settings.
