I want to be able to control my CPU fan speed W/O using the BIOS

My CPU package temperature is getting up to around 90c when I'm playing Civ V. I've found that setting my fan speed to full the temp stays at a more reasonable level. I don't want my fan to be on full blast all the time though, only when I'm playing this one game. It's kind of a pain to shut down my system every time I want to change the fan speed, so I want a way to control the fan speed without having to power off my computer and setting the speed in the BIOS every time. I've downloaded SpeedFan, but I've had little success getting it to do what I want it to and I don't think the program can get an accurate read on my hardware's temperature because it shows that my core temp is 0c and I'm pretty sure nothing in there is freezing. So basically what I'm looking for is a way to control my CPU fan's speed from the desktop.

  1. speedfan looks at sensors that may not be in use, it can also show them at 144c which is unlikely. You can change what displays on front screen.

    what motherboard do you have? some of them have their own software you can use for this..

    i tend to let bios do it as I have made mistake of taking manual control of gpu fan before and it was a pain having to adjust it constantly. I tried to let the Asus software do it last year and it didn't work as planned.IT actually turned CPU fan off completely which was not amusing.
  2. My MoBo is a GIGABYTE GA-F2A88XM-D3H FM2+ / FM2 AMD A88X (Bolton D4) SATA 6Gb/s USB 3.0 HDMI Micro ATX AMD. I had a similar problem with my GPU. When I was playing games the fan would keep revving up every few minutes or so. It was super annoying. As it turns out the GPU was over heating and the fan was going full blast to put out the fire. So now I'm running a program that lets me set the speed based on how hot the thing gets and it's working out really well. The fan never has to go above 35% of it's full speed and the card temp stays at a reasonable level. I'm hoping to find something that can do the same for my CPU.

    Take a look at the AMD CPU Temperature Guide at the top of the CPU forum. Third-party software rarely reads the correct temperatures. AMD Overdrive shows a thermal margin between 0 and 70 degrees Celsius, if you're anything upwards of 0 under load, you're fine. SpeedFan seems to display 70 degrees minus the thermal margin, which makes it quite a reliable reading, just keep in mind that the actual temperatures are slightly higher and you should keep SpeedFan below 70C.
  4. I just installed OverDrive and it says that it can't detect an AMD CPU or my CPU is not supported by this program. I'm using a AMD A10-7700K Kaveri 10 Compute Cores (4 CPU + 6 GPU) 3.4 GHz Socket FM2+ 95W Desktop Processor AMD Radeon R7 series ... I guess that technically makes it an APU, but I didn't think that would make a difference.

    Your CPU is supported by OverDrive. Updating the BIOS seems to help in some cases so install @BIOS from Gigabyte if you haven't already: http://www.gigabyte.com/support-downloads/utility.aspx. Scroll down to @BIOS for AMD FM2+/AM3+ series and download it.

    It should be clear enough from there. Please be aware of the risks that a BIOS update brings so close all open programs before you start the update. It's possible that Windows won't boot after that, in that case you should fully power off your pc and disconnect the PSU (take the battery out if there is one), wait 30 seconds before starting it up again and immediately go into the BIOS to reset to the factory defaults. I've had this happen on my own Gigabyte mobo.
