Mac Hdd Fan Control [BETTER] Crackl
Replacement Hard Drives or SSD's in an iMac cause the HDD Fan to run at full speed. Unlike other Fan Control Software, HDD Fan Control completely controls the fan speed making it run correctly again.
Mac Hdd Fan Control Crackl
Unlike other Fan Control Software which can only increase the fan speed. HDD Fan Control directly controls the speed of the HDD Fan slowing it down when the drive is cool, and speeding it up to protect the drive from overheating when hot.
We are constantly improving and testing the temperature control algorithm with new Hard Disks and SSD's to make sure we provide the best fan control possible, as such you get free Automatic updates of HDD Fan Control.
HDD Fan Control controls fan speed in relation to drive temperature. If you have replaced your iMac's Hard Drive with a new Hard Drive or a SSD and the fan has started running at full speed creating a lot of noise, HDD Fan Control will control the fan speed, preventing the loud noise whilst keeping your drive safe.
NOTE: This app is specifically designed to control your HDD Fan using your drives S.M.A.R.T data for iMacs with replacement drives which no longer provide correct temperature data to Apple's sensor.
HDD Fan Control will run the fan at the correct speed, and keep your drive cool and safe from overheating. If you are looking for an application to adjust your Mac's fans from stock (and not to control fan noise after replacement disk) we can highly recommend the free smcFanControl or iStat Menus
Macs Fan Control allows you to monitor and control almost any aspect of your computer's fans, with support for controlling fan speed, temperature sensors pane, menu-bar icon, and autostart with system option.
Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they generate. This is commonly accomplished by the motherboards having hardware monitoring circuitry, which can be configured by the end-user through BIOS or other software to perform fan control.
In this style of fan control, the fan is either on or off. Temperature inside the chassis is checked, and if an outside-of-range temperature is detected, fans are set to their maximum speed. When the temperature drops below a threshold again, the fans are turned back off. This control method reduces noise issues and power requirements during periods of low usage, but when the system is operating at capacity, the fan noise can become a problem again.
Resistors in series with a fan's power pin are the simplest method of reducing fan noise, but they add to the heat generated inside the computer case. Since the voltage drop is proportional to the current, the fan may not start. They need to be of the appropriate power rating. For variable fan control, potentiometers could be used along with a transistor such as a MOSFET whose output voltage is controlled by the potentiometer. It is possible to use a rheostat instead.
Pulse-width modulation (PWM) is a common method of controlling computer fans. A PWM-capable fan is usually connected to a 4-pin connector (pinout: Ground, +12 V, sense, control). The sense pin is used to relay the rotation speed of the fan and the control pin is an open-drain or open-collector output, which requires a pull-up to 5 V or 3.3 V in the fan. Unlike linear voltage regulation, where the fan voltage is proportional to the speed, the fan is driven with a constant supply voltage; the speed control is performed by the fan based on the control signal.
The control signal is a square wave operating at 25 kHz, with the duty cycle determining the fan speed. 25 kHz is used to raise the sound of the signal above the range of human hearing; use of a lower frequency could produce an audible hum or whine. Typically a fan can be driven between about 30% and 100% of the rated fan speed, using a signal with up to 100% duty cycle. The exact speed behavior at low control levels (linear, off until a threshold value, or a minimum speed until a threshold) is manufacturer dependent.
Another method, popular with PC hardware enthusiasts, is the manual fan speed controller. They can be mounted in an expansion slot or a 5.25" or 3.5" drive bay or come built into a computer's case. Using switches or knobs, attached fans can have their speeds adjusted by one of the above methods.
Many companies now provide software to control fan speeds on their motherboards under Microsoft Windows or Mac OS X/MacOS. Different software is used by different motherboards. There are also third-party programs that work on a variety of motherboards and allow wide customization of fan behavior depending on temperature readings from the motherboard, CPU, and GPU sensors, as well as allowing manual control. Two such programs are SpeedFan and Argus Monitor.
Some of the software aliases include "HDD Fan Control Monitor". HDD Fan Control for Mac relates to System Tools. The bundle id for this application is me.surtees.HDD-Fan-Control-Monitor. The latest version of the application can be downloaded for Mac OS X 10.6 or later. This Mac application was originally developed by Surtees Studios Ltd. The latest installation package occupies 3.1 MB on disk. The HDD Fan Control installer is commonly called hdd_fan_control.dmg or HDD Fan Control.dmg etc.
smcFanControl is perhaps the most well-known fan control app because it's been around for several years. It allows you to monitor the temperature of the CPU, GPU, and boot disk in the Mac's menu bar, and you can set temperatures for each fan on your Mac individually. There are three presets available, one for when your Mac is running on battery power, one for when it's running on mains power, and one for when it's charging. That way, you can ensure the fans don't drain the battery but also keep your Mac as cool as possible when it's plugged in.
The good news is that TG Pro supports macOS Monterey and Apple Silicon and is notarized by Apple. It gives you full sight of temperature sensors for CPU, GPU, logic board, battery, and boot disk. And you can control fans manually or set custom rules to determine when the fans kick in. Worried about your Mac overheating? Have the fans start at a lower temperature. Need to keep your Mac quiet? Set the temperature a little higher.
By itself, this software can solve the fan rev up issue. Combine that with the short solution above, and you appear to have an iMac with fans under control and that you can run Apple Hardware Test (AHT) with normal results.
Apple custom firmware on factory drives outputs a digital signal that provides SMC with the HD temperature information so it can control fan speed. The thermistor(apple 2010 optical thermal sensor ) you installed simply shorts the line in the 2011 iMac when installed as you have done. Unlike the digital thermal sensor we provide in our 2011 iMac HDD upgrade kits, a thermister is effectively makes use of a resister that varies in resistance to depending on temperature which a system designed to use such then determines temperature by voltage level.
We actually have a few interesting test scenarios in play today to get a better understanding of how the thermal data is being communicated with the new scheme. We still have hope for a solution that will keep the Apple thermal monitoring and fan control operational while allowing a non-Apple Rom HDD be installed into this bay.
According to the Wikipedia page for SATA ( _ATA ), there are 15 pins on SATA Power but only 5 different lines: GND, 3.3, 5, 12, and a pin that can be used for spin-up control or for an activity LED. I wonder if Apple drives have modified firmware that pulses that line at a rate based on temperature
My guess is that either the iMac cooling system is far more fragile than we all understand and they need to keep that under tight control, or that Apple is planning to use some new variation on drive technology that will require special connectors. You could make arguments for either and both.
As with all such hardware updates and associated utility software since the dawn of the industry, if there was a change in the available fans then any 3rd-party utilities that control them will need an update as well. This also is not news, and there should be no surprise if the solution people were using for the previous iMac needs an update for the new one; if anything, there should be a simple reaching-out to provide assistance to the developer in question.

Resetting SMC (system management controller) has long been a reliable hack for taking control of the thermal management of the MacBook. When the fan of the notebook runs high, it comes in handy in cooling it down.
