Imac Cpu Fan 4000 Rpm

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.

Imac cpu fan 4000 rpm.

The cpu fan still went 4000 rpm and the conclusion was that it is a faulty owc cable. There are two reasons you d want to do this to allow your mac to run faster but louder or slower but quieter. 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. Hi all ye i have some temp problems.

The free macs fan control app lets you manually control your fans. 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. This is what happens every time i restart my imac.

But my question is can this hurt the fan if its spinning almos. Mac s fan control is definitely doing the job for now i m using the cpu heatsink temp as my rpm controller. To resolve the issue reset the smc your mac should now start up and work as expected. To find out if your fans are working at all you can click the custom speed button.

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. If you see high cpu temperatures say over 80 or 90 degrees and that the fans aren t running you might have an issue. The same goes if you see a low cpu temperature say around 45 and the fans are running at full speed. The cpu fan will start ramping up speed slowly until it seems to be maxed out around 4000 rpm noisy.

The odd fan s rpms are strangely high but it s the cpu fan that s out of control. I dont care much now about the big sound it makes because i use a headset in game. After running full speed for anywhere from 5 minutes to 30 minutes the computer screen goes black.
