I have recently naught a saphire r9 280x, whilst benchmarking and playing games on it last night, I noticed a low pitched squeal, should I use my warranty, is this bad, I think but don't know for sure that it's a coil or capacitor squeal
I am not 100% sure but I am fairly sure that there is very rarely any negative side affects to coil whine other than the whine itself. But I would still advice playing it safe and asking for a replacement.
