Xbox One fan and HDD noise

A clicking noise would be either A) the fan off balance at low RPM or B) the HDD. The HDD would only make noise while seeking though so probably your fan if it's constant.

Yeah I hear you. It's not right having to put up with the annoying sound of a fan whirring constantly but that's not to say it's going to fail. I have a couple of noisy fans in my PC, one of which is nearly 5 years old and is still going strong. Granted,
some fans do have inherent problems with bearings/coils and will unfortunately grind to a stop one day but that's just the risk we all take with electronics.

With all that said though, and this has just come to me, high pitched squeaking noises sometimes come from HDD's. I personally can't here these noises as I have an inner ear condition called tinnitus, but if that's what some of you are hearing it could be
the HDD's making the noise and not the fan. If that's the case then it's a game changer because through experience HDD's making high pitched squeaking noises are already on their way out and you'll need to get it serviced sharpish.

Damn! I've been installing games and haven't had to deal with this fan noise in a long time. I've got a slim but no HDD. I just ordered one from Amazon. I can't stand this noise! The slim will handle the game better then this old model.

Same problem it seems to get worse when the game is more graphics intensive

I think its normal. My One makes the same noise, for example I can apreciatte when I press pause in NBA 2k14....did you try with that game? I think is the normal noise from HDD depending the game.
