[QUOTE="Andy"]\nyou seem to miss my point that I am saying that my Dimension 2400 (P4\n2ghz) fan always ran at low speed and in the Dell diagnostics showed a\ntemp sensor and fan speed - the same can be applied to the Vostro 200\nwith 1.6 Duo Core I am sure without any damage - I am even going to look\ninto reducing the Vostro's fans from 2 to 1 because I don't really think\nthat this configuration needs 2 fans running. The processor and\ntemperature in my Vostro run no hotter than my Dimension 2400 which only\nhad one fan so why should I have to have 2 on my Vostro?\n\nAndy.\n[/QUOTE]\nThe point you are missing is that the 2400 fan only had one speed -LOW-\nbecause that was all it ever needed to cool that system which produced\nalot less heat. Newer computers can produce much more heat not only\nfrom the processor but the chip set as well as the video and\nfaster(=more heat) hard drives. My 2400 is also quiet but my 4600 makes\na little more noise when it gets warm. Don't reboot as much and you\nwon't notice it as much.
