The Northbridge chipset fan has stopped functioning on my Asus A8N-SLI Deluxe. On system startup, the BIOS presents the following message:
*** Warning:Your Computer CHIP Fan Fail or speed too low***
You can also disable this warning message in SETUP
While the motherboard is under warranty, forum discussions indicate that even the replacement fan is likely to fail. A recommended solution is to instead install the Zalman NB47J, which is passively cooled and has no moving parts. It is listed as $4.99 on Newegg.
If you still want to replace the original faulty part from Asus, see the following e-mail:
