The problem of loud fans in iMac computers is not a rarity. Lately, Apple has been trying to improve the energy efficiency of their products by using more efficient processors and a secondary fan to exhaust the hot air from the interior of the iMac.
UNDERSTANDING THE PROBLEM
This problem began in 2012 with the launch of the 21.5 iMac and has continued in the late 2014 versions. Specifically we are talking about the 21.5 inch models of the late 2009, 2010, 2011 and 2012 series, as well as the 21.5 from 2013-2014.
The fans in these computers are very loud; they begin to accelerate at temperatures exceeding 45 degrees Celsius, and that is a normal temperature increases when we use them for gaming, photo or video editing and other activities that require greater performance.
A loud fan in an iMac computer can be a problem for users. The fan noise can become loud when the computer is used for gaming, video editing, or other resource-intensive activities. The issue seems to be affecting 21.5-inch iMac models from 2009-2014. Apple has tried to improve the energy efficiency of their products by using more efficient processors and a secondary fan to exhaust the hot air from the interior of the iMac; however, this has not alleviated the problem for many users.
There are a few things that users can do to try and reduce the noise coming from their iMac’s fan. One is to keep the room temperature cool; if the ambient temperature is lower, then your iMac won’t have to work as hard to keep itself cool, and thus the fan shouldn’t run as often or as loudly. Another option is to use software like smcFanControl to monitor and control your fans manually. This can give you more fine-grained control over how often and how quickly your fans spin up in response to increased temperatures.
Ultimately, though, if your iMac’s fan is too loud for comfort even after taking these steps, you may want to consider contacting to the local repair shop.
