My 3 year old notebook CPU fan broke down last week. I intend to get the fan replaced, but there's no stock in my area, so I'm temporarily using my notebook with a notebook cooler. To ensure the notebook cooler is cooling my notebook, I installed speedfan to monitor the CPU temp, and indeed the cooler is working as it should. However, I notice right after my notebook fan broke down last week, the notebook speed becomes slower, and sluggish. The CPU is also running higher, ie., in the range of 20-30%, as compared to 4-10%, even on idle. I'm sure it's not malware or virus, as I'm always online sanboxed with Prevx and Hitman Pro on demand. Could this indicates some other hardware problems other than a broken fan? I'm running on Vista Home Premium SP2.
