Probably because the fan does not have an RPM sensor which tells the BIOS if the fan is working properly. Although I have read forum posts from users that had replaced the Dell fan with one that was not Dell but had the sensor and still got an error. The following posts should help. Read through to the end. Just wondering, how many pins was the Dell fan and how many on the new fan you installed?
