from what I gather SMC fan control takes less space/resources on the cpu and the machine. I would think that an engineer working on Istat Menus would know right away the difference and vice versa. This is a good argument against leaving your Mac plugged in all of the time, but keep in mind that taxing the hardware will also cause it to use more power. Option 1) you may consider using inbuilt utility powermetrics to get the cpu and gpu temperature and lot more other details. SMC fan control probably work more closely with the SMC chip and I suspect Istat Menus gets it from a derived version more software. Hotter air cannot disperse as much heat as cooler air, and the problem is even worse if the humidity is high too. If you like to use your MacBook on your lap or on a surface that may obscure airflow (like a bed) then you will greatly impact the machine's ability to cool itself.Ĭharging and using your Mac at the same time can also cause heat buildup at a much faster rate since the battery produces heat when charged. iStat Menus normal temperatures and fan speeds Mid-iMac2011 2.7GHz 12,2 Late-2014 iMac 27 3.5GHz 15,1 Looking for a chart or some listing of range of normal temperatures/fan speeds for these to using paid version of iStat Menus Finding a variety of here and there listed by members, thank you but, surely there must be a listing somewhere. Using your Mac in a hot environment will cause it to naturally run hotter. You can combat this by opening up your Mac and giving it a good clean.Īmbient temperature can also have a big impact on your Mac's ability to cool itself. This causes your machine to run hotter as it ages, which may also result in more audible fan noise. Over time the inside of your Mac will gather dust, and this dust hinders heat dispersion. It’s unrivaled in terms of the amount of insights it gives you about your Mac. But we assure you that even after checking dozens of temperature control tools for Mac, you’ll want to go back to iStat. Take note you are limited to the minimum value that Apple sets, so you can’t damage your hardware.Heat buildup can be aggravated by other factors, one of which is dust. iStat Menus the best macOS temperature monitor A bold statement, we know. If you’re having a noise problem, you can lower this value, but make sure you keep an eye on the temperatures. This fan control tool has been used for years to set a minimum rpm value for the built-in fans. Also, it’s free, so it’s worth trying it out before buying a premium app. Keep in mind that it won’t work on the new M1 Macs, but it should be compatible with the Intel builds. Displays a status bar with current fan speed and HDD temperature.Īlthough smcFanControl is outdated because it has been discontinued, you can still use it on an older iMac, MacBook Air, or MacBook Pro.Controls the fan automatically for optimal HDD/SSD cooling.If your HDD or SSD doesn’t come with a SMART interface, the app will still approximate the temperature of your hardware based on the other sensors.įind the right balance between temperature, cooling, and noise by setting a custom relationship between fan rpm and HDD temperature. In the example above, iStat Menus will use My Fan Set when any sensor is above 80✬. Sensors A realtime view of temperatures, hard drive temperatures (where supported), fans, voltages, current and power. status monitoring, detailed disk I/O, and a variety of different read and write indicators. Edit the rule to suit what you are after. Disk usage & activity See used and free space for multiple disks in your menubar. I can set the fan speed manually via iStat Menus fan control, but this is not an ideal solution. Click the + to the right side of the window. I installed iStat Menus 4.04 on my new retina MacBook Pro 13, and now the fans will not automatically increase when the CPU gets hot ( around 95 Celsius). Instead, it uses the hard disk’s integrated SMART interface to get the data it needs. To use automatic fan set switching, choose Automatic from the Fans menu in the sensor menu bar item. The best thing about HDD Fan Control is that it doesn’t rely on Apple’s temperature sensors.
