GPU fan speed under OSX

Recommended Posts

Hi,

how can I control the fan speed of my GPU under OSX?

At the moment my GTX 970 is always running on the same fan speed. Is this normal? How can I monitor my temperature under OS X? Under Windows the fan speed changes automatically.

Thanks a lot for your help guys!

In general the fan speed of the eGPU should be controlled by the GPUs BIOS. In Windows you can run tools to edit the fan profile, in OSX it should run with the stock fan profile.

For example my eGPU has an edited fan profile in Windows to ramp up the fans very late. In OSX the fans spin up very early if there is any 3D load on them.

How did you test in OSX? Have you tried any Unigine benchmark and monitored the GPU temperature? Anything below 80°C is fine.

Hi,

sorry for my late reply.

Unfortunately I have no chance to find out which temperature my GPU has under MacOSX or I simply don´t know how to find it out. The GPU temperature is not visible in any temperature monitor software. I recently installed the latest drivers and at the moment I am running OSX 10.10.4.

Best,

Michael

You need to modify OSX system files in order to change fan behavior. You will need to look online to find a GPU monitoring tool for OSX, if one exists that is being updated.

What exactly needs to be changed in the system? At the moment my GTX 970 can be already found in the "System Report" --> "Graphics/Displays".

Can someone recommend any good GPU monitoring tool for OSX?

      Hi,
       
      I am having some heat issues with the GTX 680m I installed on my Alienware M17x R2 (yes, its old).  Having installed and ran HWiNFO64, it appears that the maximum rpm of the GPU fan is 2560rpm, even when the GPU reached a maximum of 93° Celsius.  The rpm seems low, but what is the maximum rpm of the fan, does anyone have any ideas?
       
      Thanks

      When my first CPU fan on Y500 is broke i replaced it on something compatible (non-original) and planned to replace it later on original. Since that time happened a lot things, but i still using that non-original fan. But i did some research and here is what i founded:
       
      I. ORIGINALS
       
      1. Forcecon (marked as FCN on fan)
      DFS5413005MH0T-FC1C (5V - 0.5A)
      Spotted in: Y400, Y500.

       
      2. Asia Vital Components (marked as AVC on fan)
      BNTA0612R5H-P007 (5V - 0.5A)
      Spotted in: Y410p, Y500, Y510p.

       
      3. Sunon (marked as SUNON MagLev on fan)
      MG60120V1-C230-S99 (5V - 2.25W (0.45A))
      Spotted in: Y410p, Y500.

      So, which to choose? Any recomendation? Maybe there also unexpected way (completely diffirent fan from another company for another laptop)?

      Hey guys, first post, but I thought I’d discuss my heatsink fan retrofit in my old M14x r1. 
       
      Old fan was loud and not very efficient: the air transfer rate was around 2 cfm (I’m assuming cubic feet per minute). Finally had enough and decided to swap out the crappy r1 fan/coughing pinwheel for a r2 fan (rated at 10.4cfm). 
       
      I found an old r2 heat sink on eBay (beware though that the heat sink for the r2 will NOT fit the gpu/cpu configuration for the r1. HOWEVER, the fan of the r2 heat sink it is attached to is a carbon copy fit into the r1 MoBo. A few philips head screws and a seal of good electric tape and BAM, you’ve got a significantly cooler and MUCH quieter intake fan in your old R1. 
       
      My CPU temps from before were around 87-88 max load in FSX, 65 for the GPU; bear in mind this is after a repaste. Now with the new fan, I’m not going over 77 degrees on the CPU, and the gpu stays around 58, all while being MUCH quiter. I’ll post pics of the walkthrough if anyone is interested.
       
       Just thought I’d share with all you fellow loonies trying to squeeze every last frame and degree out of our “portable toaster ovens with a screen and keyboard”.

      First I want to thank the community, who have inspired me to do this project.
      I will give you guys the chance to follow me on this journey.
       
      I hope you will all help me come up with ideas, techniques and parts that could become handy.
       
      This modding may be possible to convert to allot of laptops.
       
      Let's begin!
      Here is the measurement of the went hole.
      77mm X 16mm

       
      I have 2 ideas for what can be done.

      I own a Clevo P151SM1 that I bought in a hurry last year after my Alienware died on me. It's done a good job of playing everything I've thrown at it but lately, it's been shutting itself off when I play certain games or graphics-heavy programs. When idle it sits around 38C which is great. But when I get into a game it skyrockets up to 97C as the last recorded temp before it shuts itself off. I've cleaned the fans and keep it on an elevated cooling pad (no fans on the pad cause I broke them) but it gets plenty of air. I know that 97C is probably damaging the card and I don't want that. Does it look like I'm going to have to repaste it?  I've attached my latest readings if that would help.
