Re: HP pavilion dv7 4170ED fan cooling issue

I bought a DV7 Pavilion in Feb. 2011 and just recently it has started to report Fan error 90B on initial start up.

 

At first I thought this was due to a software conflict and various upgrades later (including BIOS) I thought I had solved the problem. Now after 3 days of error free start-ups first thing in the morning I powered up only to be greeted with Fan error 90B.

 

I see the above mentions a chip set update in addition to a BIOS update I did not see anything like this on the PC BIOS support page. Can anyone confirm whether or not restricted air flow might cause this fault i.e.. a blocked vent?

 

I have on HP support instruction returned the PC to factory state and then carried out a series of OS and BIOS updates downloaded from HP support site relevant to my PC model. I use the machine heavily each day and reluctant to return for what appears to be a system check and reset back to factory state only to find on its return after 2/3 weeks the same problem appears.

 

Any meaningful help advice would be very much appreciated.
