I'm running a Intel Core i7 950, and the CPU fan has been running very slow lately, and I have been noticing that hot hardware smell. The CPU Cooler (a Cooler Master V8) fan is running at between 500-1000 rpm, although it occasionally dips even lower. However, all temperatures seem normal - the CPU cores are between 50 and 55 C, and all other internal temperatures seem normal. Should I be worried though? Asus AI suite keeps giving me low fan speed warnings (I checked values with Open Hardware Monitor too), and the BIOS gave me a warning too on startup yesterday.
