Constant fan noise on 2017 iMac even at rest

Hey Everyone,

I just upgraded from a 2012 to a 2017 iMac.  I noticed yesterday that the fan is constantly on with the new iMac - even in rest mode (not rendering or moving data etc...). I saw some articles about this.  It's really annoying especially if you work in the evening hours and the house is quiet and you want to work in absolute silence.

My old iMac had no problem with that.  Do others have the same problem?  Is there anything else besides earplugs I can do?  Would an SSD drive make a difference or a different processor type that require less energy and create less heat?

Any suggestions would be great.

Thanks,

Holger

27-inch iMac with Retina 5K display

Configuration

•   3.8GHz quad-core 7th-generation Intel Core i5 processor, Turbo Boost up to 4.2GHz

•   8GB 2400MHz DDR4

•   3TB Fusion Drive

•   Radeon Pro 580 with 8GB video memory

What's causing the fan activity depends on which fan it is. But if the fan is that noisy, I'd suggest you use your free Apple Support to get in touch with them and have it checked.

Have you tried n SMC reset?

Hi Macjack,

Thanks for the respone.  I have not done an SMC reset (I have to goodle to see what that actually is).  I just got the iMac 5 days ago - so I haven't done any hardware checking.

Are you saying that different iMac models have different Fans and that the one in the iMac I purchased just is louder in general or could this be a hardware defect?

Thanks,

Holger

No, I'm saying you have several fans in an iMac. Whichever fan it is, it may be a hardware defect. You don't have to google the SMC reset, just use the link I gave you.

Besides your free AppleCare, you also have 14 days to return the Mac for a full refund.

Holger,

A SMC reset is the normal thing to do if you have fan noise. Sometimes it takes 2-3 times for the reset to work though, so don't be discouraged if it doesn't work the first or second time. Below is a link that shows how to do it and also one for doing a PRAM reset. These are both very basic and in no way affect your data on the computer. If you want to Google them to learn what they are that's fine.
