IStat Menus also has a reading for fan RPMs. That’s about the hottest temperature you’ll see CPU and GPU proximity sensors often show temperatures in about the 145☏ range, while HDD and SDD (this device has both) temps are in the 100☏ to 120☏ range respectively. Just to give you an idea of the temperatures that are typical inside a modern Mac, my iMac (quad-core i7) just showed temperatures in the high 190 – low 200☏ range on the individual CPU cores. Later on, you can compare those readings with the baseline to see just how hot your Mac is running. If you’re getting a new Mac, installing iStat Menus and taking a set of baseline temperature readings after it has finished Spotlight and Photos indexing and is just sitting idle is a great idea.

This app is not only useful for determining which app or daemon might be slowing down your Mac, but it has the ability to grab temperature readings from a number of sensors inside your Mac (see image at right). I have a favorite tool that I use to keep an eye on internal temperatures throughout my 27-inch Retina 5K iMac - iStat Menus. One telltale sign that you might need to get the dust out of your Mac is that the internal fan will frequently spin-up, even when the computer is not under a heavy CPU load. (Temperature and fan speed readings from iStat Menus) At this time, the only Macs that can really receive a good cleaning at home or office are the Mac Pro (both pre- and post-2013 models) and the Mac mini. iFixit, which tears down new models in order to determine repairability and components used in each Mac, gave the new MBP a 1 out of 10 score for repairability. Take one of the new 15-inch MacBook Pro with Touch Bar models, for example. Where many old Macs could be opened by loosening a few screws or opening a “hatch”, today’s designs aren’t meant to be user accessible.

Today we’ll look at what Macs can be cleaned and how to clean them to prevent a dust buildup, and also talk about external cleaning that can and should be done.Īpple’s Mac designs are becoming more tightly sealed and less amenable to cleaning. Macs with internal fans for cooling have a tendency to pull in tiny dust particles which can then settle on internal components, eventually creating a “blanket” that can heat up those components and cause them to fail. But there are still members of the Mac family that can be defeated by a common foe - dust. Our Macs are remarkably reliable and are evolving to be even more reliable as moving parts like fans and hard disk drives are replaced with passive cooling systems and solid state drives.
