27 inch iMac Late 2012 fan concern

Does anyone else suffer from an imac that always has the fans on 1200 rpm and can hear it a little from the second it boots untill it sleeps?

1200 RPM is the idle speed.

I presume you use a 2012 iMac?

If it's not normal. Call Apple and get it replaced.

Is your idle speed lower? And if so, what is it exactly?

I've tried the reset a couple times. The fans are always between 1200 and 1195 but from when i turn the imac on till it sleeps i can hear the fans its not to loud but noticeable if its quiet. Just wondering if i should be concerned

Call Apple support and ask them if the speeds are normal.

Mine idles at 1200 RPM during use (until it sleeps), and I can hear it if I put my ear up to the screen and listen closely.

So yes, it's normal behavior to always be at 1200. The sound doesn't bother me, so A, you're more sensitive to it than me, or B, your fans are unusually loud.

1200rpm is the idle speed. The fan will ALWAYS run at 1200rpm when idling/not under load (I've seen it between 1195rpm and 1202rpm if my memory serves). So yes, it's normal. I personally can't hear the fan in my room, but there's a little ambient sound here anyway. If you're hearing it it must be REALLY quiet where your iMac is located.

Anyway, there you go. Normal.

Can I ask... What is the sound like? Mine sounds a little like an engine. I can hear each turn, it's not just wind but a faint clicking sound. But it's very weak and I need to put my head close to the screen to hear it. Is this what you are experiencing?

edit: I was going to record the sound so you could hear. But, now I canīt really hear anything at all. I guess this fan sound came after playing diablo for a couple of hours. it was faint, but it just did sound a bit unusual...I used to just hear an even wind sound from my apple laptop.

But, I bought a 2big Lacie HDD, which completely overshadows the imac fan sound. I cant hear anything from the imac because the lacie has a loud windy noise.

If you only read the topic title and this last post it sounds like a huge troll

I've read a few complaints about the fan noise. Most common response by users here: "if you don't trust it, get it replaced"

I don't know if it's annoying or not. Maybe you can record it for us?

Well i called apple and the rep who was very cool, had me smc reset again and it did not really change he said if its not that loud it's normal for the new imac considering the lack of space inside the mac now. He said if it gets louder than this average audible level to call back.

I'd suggest going to an Apple Store and comparing if possible. I know it's a louder environment....

Hmm. Saying that, I really, really cannot hear my 2012 iMac. How quiet is the room it's in? If you live out in the boonies you might well be able to hear it a little, I don't doubt. In a city with traffic outside, you won't.

Its pretty quiet considering i don't live near main roads and the mac is in the back part of the house! the Noise isnt terrible but idk if its worth getting an exchange considering people having worse problems.

I basically hear white noise.

I think either you need to exchange it if you think something is wrong, or deal with the fact that 1200rpm will make SOME noise, and depending on how sensitive you are to it you will hear it or you won't! That's about the long and the long of it.

Hate to be ignorant here, but how are people finding their fan speed? Only way I can find online is through obnoxious extra applications.
