I recently bought fans on eBay to replace the ones on my graphics card. When they came, I installed them and they seemed to not work correctly. At the lowest preset RPM (idle), you can hear them ramp up and down a bit, as if there is an issue with the current or something. I placed my old ones back in and they ran fine, that is when I checked the back of both sets of fans and saw there was a difference in the amps. My original fans are 12V .55a, the new ones are 12V .35a, could this potentially be an issue? Is there something I should be doing when switching to these fans or are they likely just defective?
Any help would be appreciated, thanks.
