I'm getting a System Fan error 90B on HP Envy Beats edition 1114. on HP Support website i have found solutions like hardware reset and ... and i have tried them all but the same error still exist. so according to them i have to replace the fan. problems is there are 2 fans! which one should i replace? because from the looks of them, both are spinning and i can feel almost the same amount of air pressure produced by both fans (on my hand). i can replace them both but the owner doesn't want to pay too much. can anyone help?

Well, the outlook is not good on that error message; link:   http://h30434.www3.hp.com/t5/Other-Notebook-PC-Questions/HP-Pavilian-System-Fan-90B-Error/td-p/379073

The only time a computer ever shut down on me with a fan error message is when the CPU either overheated or would not start because I had plugged the CPU fan into an incorrect plug, not the the FAN_1 socket on the mainboard. If you are going to replace any fan, the CPU would be first choice. However, from what I gleaned from that website, that may not be the problem. Unfortunately, HP for the last couple of years has numerous problems with its lap units, especially overheating problems. If you are not experienced in removing the mainboard and replacing the heatsink fan, be careful. Sometimes it's better to hand the unit back to the owner and let him deal with it. You touch it, it becomes your responsibility. Just one man's opinion.
