Q: iMac fans running full power

The fans run at full power soon after my iMac is turned on and even running only Firefox. (I have a 2.8GHz Intel core 2 Duo 4GB 800MHz iMac.) I have reset PRAM/NVRAM but it makes no difference either. I have also reset the SMC. Any idea how I can fix this?

iMac (24-inch Early 2008), Mac OS X (10.6.8)
