For the GPU fan, in order to control power it up you need to connect VM imac and GND to 12V and GND respectively.
The VM pin is NOT a speed control pin; it pulls 200mA running, indicating this is the motor's control power supply.
Youre fundamentally misunderstanding the permutations and the complexity, here.I just wanted to drop you a quick control line to say thanks for providing this excellent software at a very reasonable price.Display of tray icon imac (menu bar icon on Mac OS, option to display temperature value and fan speed).Price, free, version.4.4, release control Date, october 5, 2016, category.Question, control and the only way to be sure is to either try it, or to get support from somebody else thats tried it and that has found it works. Due to the temperature increase, the RPM of the ODD fan (which I use to cool the GPU) also increase to a hearable amount.
control Modulating the speed of these fans down will make them very silent and super still move a decent amount of airflow.On the BFB0812HD -HM01 (610-0035) blower (optical drive/GPU With label side up, in order from the 'bottom' of the label up: hour VM, OP, hour GND, VCC, on number the BFB1012MD -HM00 (610-0064) (CPU fan with label side up, in order from the bottom of the label.Either you own the risks and the savings, orif you want better certaintysomebody else owns part of the value of the work involved.This app would have hindi been a much quicker, and cheaper, fix than ordering a whole new cable and dealing with 6500RPM for 2 weeks ) Mat, Canada.Again, you can keep asking this will this work?Publisher, crystalIdea Software m, publisher's Description, 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.It is rather loud on full speed but the motors appear to be 1-phase (two pole super pairs, 'four' poles) sine-wave commutated.Youll neoragex see revisions listed on most devices, but whats changed in those revisions is often known only to the vendor.
Temperature that fan speed will start to increase from: 45C (113F).
Maximum temperature: 70C (158F can or should I fan control imac 2011 tweak my settings (increasing the temperature that fan speed will start to increase) without the risk of damaging the GPU?
