From yesterday my card has been making a noise (beside normal fan noise) like a vibration or something like that. This noise only happen when fan speed is between 60% ~ 64%. I have done a test: set fan speed at 50% (this speed is very quiet) and start to going up every ten seconds. At 59% everything is normal (obviously more noise than before, but still is low). When I go up to 60% start another noise which is constant until 64%. When I set to 65%, that noise disappear and I don't see it more.

What can be this? Would I to need rma this card?


PD: Sorry my writing, but english isn't my native language.
