Y410p/Y510p GPU fan control?

Recommended Posts

I was wondering if theres any software that would be able to manually control the fan speeds on Y series notebooks

speedfan and other software doesnt detect the fan. BIOS, no luck

Is there any driversavailable to do this

i've searched for a while, and i was unable to find something that gave me direct access of the fans. maybe, if someone were to snoop around the lenovo packages, they could find out what triggers the fans when you use the "clean dust" function.

as far as i know, there is no such software. it may be possible to reverse engineer the lenovo energy program, and read what it does when it does a fan decluttering, as that revs up both fans to 100%.

Been wondering this for some time now..

How comes Lenovo's power management "Dust removal" make connection with i'm guessing bios to control the fan speed? Or control the fan speed in any way at all.

There must be some sort of exploit in that software.

For example; when clicking "Dust removal" the exploited version would run the fans constantly, not on and off like it does.

I hope someone can shed some light on this to either help or to put my mind at rest, as I've tried to decompile the software but I Ai t got a clue xD

Thanks!

With the EC. Without having documentation it's super tricky. You could politely ask @Mumak, he might be able to support fan control for this machine in HwInfo (it's Compal-based) as he had some success with AW systems, but he's usually super busy, so you might have to be patient to get a reply.

Best will be to head to the HwInfo main thread for this.

Only way is trough EC, since every temp and fan related settings in unlocked bios does nothing at all. Fan is not controlled via bios and ME.

Yeah I've tried it. It actually makes the laptop run hotter because the delay between when the fan spins is too long.

I just tried AIDA64 with the script, idle temp for my system is 43C, without the script the core temp is 86-87C, with the script it is around 80-81C. During the pauses the temp rises to 83C then comes back down to 80C. I have a y510P 4700MQ with 755m single GPU.

You probably didn't let it run long enough or it's not putting constant 100% load on your CPU and GPU. Like I said, for me the max temperature is higher with script than without script. I tested by playing PlanetSide 2 for a few hours. It's a game which has power virus characteristics, meaning it draws an inordinate amount of power from my GPU's, and they are at constant 99% usage. The difference is especially apparent on my Ultrabay GPU, which normally has a 10-15C temperature delta under full load from the primary card. During the breaks when the fans are not spinning, my components heat up by 3-5C, and when the fans turn back on it doesn't lower temperatures enough to make up for the increase. So it's basically continuously heating up. One step forward, two steps back, if you will. Without the fan script, at least temperatures stop rising after a certain point.

I don't have Planetside 2, but I will try running AIDA64 for a longer duration. How long do you suggest?

As long as it takes for temps to stabilize.

BTW PlanetSide 2 is a free game and it's awesome. :D

Just tried AIDA for 2 hours with everything checked (CPU/GPU/Memory/Cache/Disk) its around 86-87C with the script and 92-93C without it (ambient temp 40C). The pauses increases the temp by 3C, if I had SLI then the script probably isn't worth it. Let hope Erni3 comes up with a better one. And thanks for the PS2 suggestion, it is indeed awesome:)

Yeah probably. It's primarily my second GPU that heats up more when using the script.

You can now try IdeaFan http://forum.techinferno.com/lenovo-ibm/7358-ideafan-y510p.html

I have a similar? problem with my y510p where the fan doesn't run as much as it should for the load that I'm putting on the system. I know the fan works because the Lenovo Remove Dust utility works but otherwise the fan hardly seems to come on

      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)?

      Recently obtained myself a bricked Y410P after undervolting my CPU, using svl7's bios mod on TechInferno. If you only take one thing away from this post, it should be the fact that 
      NEVER SHOULD YOU EVER UNDERVOLT A LAPTOP CPU FROM A MODDED BIOS. Hindsight is never 20/20.
      Anyways, back to topic! 
       
      I went and purchased my self one of these, in hopes of to re-program my sad bios. So far no good. 
       
      I am wondering if anyone out there have had any success with this approach. Please share your journey here!

      In case you own a Lenovo Y410p or Y510p laptop, you might be interested in upgrading its performance by installing an external graphics card. Ultrabay eGPU adapter designed by @gerald was proven to be a convenient plug-and-play option to do exactly that. However, for a long time only an AMD-branded GPUs could be used due to limitations in the Lenovo's stock BIOS. The purpose of the modified firmware presented here is to expand the range of available GPUs by enabling Nvidia support on Gerald's Ultrabay eGPU adapter.
       
      Huge thanks to:
      @MWichni - For efficiently assisting me during the development of this mod. By flashing dozens of BIOS builds over the course of several weeks and thoroughly describing the effects observed (or the lack thereof), he enabled me to fully understand necessary parts in BIOS structure and come up with a final solution. @svl7 - Whose unlocked BIOS / Whitelist mod has served as a basis for this modification. His discovery of a security hole in V2.07 BIOS has provided us with a convenient BIOS flashing method that does not require a physical programmer. The Unlocked BIOS and WLAN whitelist mods originally designed by him are also implemented in this BIOS mod. @gerald - For designing the aforementioned adapter. Without it, all this work would make very little sense.  
      Key features:
      Resolves the "40-second reboot" issue normally encountered while using Nvidia graphics cards with Ultrabay eGPU adapter, thus allowing all Nvidia cards to be used. Based on the latest V3.08 BIOS. Includes Svl7's WLAN whitelist removal mod - for the convenience of aftermarket WLAN card users. Includes Svl7's BIOS debug menu mod - for the ease of experimentation with newly available features, e.g. attempting to use Nvidia Optimus to pass eGPU video back to laptop's display.  
      NB! Svl7's Debug Menu is not a toy! It contains a lot of options that are either not supported or partially supported by the hardware platform and/or can disturb its normal operation or prevent the PC from booting up at all. Any of the entries not originally present in the stock BIOS should be modified at your own risk!
       
      DISCLAIMER:
      ANY MODIFICATIONS YOU ARE APPLYING TO YOUR HARDWARE ARE PERFORMED AT YOUR OWN RISK! AUTHOR OF THIS MOD DOES NOT HOLD ANY LIABILITY FOR LOSS OR DAMAGE RELATED TO USING THIS SOFTWARE.

      Installation instructions:
       
      If things don't go right:
       
      Error 43:
      If you intend using the GTX10XX-series Nvidia card as the eGPU (which you probably do), you are very likely to encounter the infamous Error 43 in Windows Device Manager. This is a widely known issue in the eGPU community and is not related to this particular mod in any way. Following this guide thoroughly will in most cases resolve the Error 43 issue.

      Version of this mod for Lenovo Y400/Y500 models is coming soon!

      Hey sorry for my bad english and sorry if this question is kinda stupid..
      So i have a y500 650m SLI and already flashed the bios.
      I thought about getting myself a EXP GDC v8 + 220W Dell power brick and a 1050 Ti from Zotac.
      i googled a bit and found some ppl saying that the y500 model 1(? - i don't know which one i have) only has mPCIE x1 - so whatever it is they say it's kinda slow.
      So my questions are, do i only have 1x PCIE, how can i find out and to what "powerer degree" of graphics card can i get, that doesnt suffer from power loss then?! Is a 1050Ti ok für that PCIE 1x?
       
      i attached a screen of my nvidia inspector window maybe it helps

      Every once and a while, my fan will start rattling, and everything works fine, but it is just extremely annoying and I don't know how to make it stop. I tried using the dust cleaning function of the lenovo battery application, and it helped a little but occasionally it will start making the noise, and it is really loud and concerning because I hope it is not indicating any other more pressing issues with the Y500.
