I have a Dimension E521 where the front Nidec 120mm fan died on it. The unit is out of warranty, and apparently Nidec does not make the TA450DC fan anymore. I instead went with a standard 120mm fan that hooks in via the power supply feeds (in other words, it is not powered by Dell's rediculous proprietary 5 pin motherboard plug). The fan works great, and the system is ice cold, but every boot the BIOS gives me the: Alert! CPU Fan failure. I don't want to have to hit F1 every time I start my computer just to see it boot. I have the most current BIOS (A07) and there seems to be no setting to stop this alert. I have already shut off reporting Keyboard Errors (which some people allege fixes the problem, but doesn't). I think it's absurd that I'll have to resort to tricking the motherboard into thinking the CPU fan exists (LED lights or resistors) just to get around a BIOS check that I don't want. So, is there an easy fix for this, either on the motherboard or in the BIOS? -R92 PS- It's also a little silly to have to take the heat sink off the CPU just to get at the case fan.. I wonder which Dell engineer green-lit that idea.. I appreciate the strides Dell has taken to streamline the case design since the early 90's tanks, but c'mon.
