Imac Cpu Fan 4000 Rpm

Here are some simple things you can try that might save you a trip.

Imac cpu fan 4000 rpm.

Apple s auto control aims for somewhere in the middle. The odd fan s rpms are strangely high but it s the cpu fan that s out of control. I am in the process of trying to get a replacement however i m worried that the problem wont go away and something else is actually wrong i dont believe the cable and my original hd had the same problem. It s not the hdd sdd temp sensor by the way since it s not the hdd fan that s spinning that hot but it certainly is one of the other sensors.

I just let the auto fan control do the job but most time it needs 90 4300rpm to keep the gpu cool. Mac s fan control is definitely doing the job for now i m using the cpu heatsink temp as my rpm controller. Hi all ye i have some temp problems. By default apple runs your mac s fans automatically with no way to configure them and it ramps them up when your system gets too hot.

To resolve the issue reset the smc your mac should now start up and work as expected. The cpu fan still went 4000 rpm and the conclusion was that it is a faulty owc cable. But my question is can this hurt the fan if its spinning almos. The free macs fan control app lets you manually control your fans.

There are two reasons you d want to do this to allow your mac to run faster but louder or slower but quieter. On mac computers that have the apple t2 security chip pressing the power button at about the same time that you plug in the power cord can cause the mac to enter a mode in which the fans run at full speed shutting down the mac and starting it up again might not resolve the issue. Are the fans in your mac or macbook roaring away at full speed making it sound like your computer is getting ready to take off. This is what happens every time i restart my imac.

After running full speed for anywhere from 5 minutes to 30 minutes the computer screen goes black. The cpu fan will start ramping up speed slowly until it seems to be maxed out around 4000 rpm noisy. If you see high cpu temperatures say over 80 or 90 degrees and that the fans aren t running you might have an issue.
