Had a rattle for some time when my GPU fans were starting off at 55C degrees temp and it was continuing till reaching like 45C. I gently pressed a fan which made the sound and now it only makes it rattle sometimes on start-off at that temp, sometimes it doesn't. I am not sure if it will become worse if I try pressing again, it happened previously, so should I leave it as it is? I doubt the best solution is to return it to reseller since they don't have these models in stock or if they will repair the fan instead of refund. It sounds similar to this.
