The best thing to do is message [NAME]-Cares as they are best suited to advice where to go from here.
My Aurora R11 is 17 months old. This morning, when I turned the desktop on,  I received a 'Critical Error Message' telling me that the 'Fan - The fan failed to respond correctly () pump failure'. I started Dell SupportAssist and checked the fans separately. The Front fan and the Top fan passed the tests.  The Pump Fan failed the test. I have followed the Dell link and the suggestions there are to clean the airways around the pump fan and to remove any dust from the fan blades. I have stripped off the side and top covers and cleaned the fan with a small vacuum. It wasn't very dusty but I cleaned it anyway. I switched off the PC and then switched it on again and got the same error message. The PC is 5 months out of warranty. I hadn't had any issues to speak of and didn't think I would need support from Dell! Can anyone suggest what I should do to remedy the problem myself? All advice would be gratefully received. Many thanks in advance. Ed (UK Dell User)
