Fan Mod Guide and Performance results.

Recommended Posts

I truly hope lenovo sees this and notes the CONSIDERABLE performance increases and take into consideration the lifespan of the laptops going up drastically. And as a result give us access to the fan speeds via software.

Many people who have purchased the Lenovo Y510P have noted its absolute lack of fan control abilities the below is half guide/half performance report. This is to show what the Y510P is capable of if it were to have unlocked fan controls which are currently impossible to access. The below is a fairly simple hardware mod that involves removing one wire from the PWM controller on the motherboard. ((difficulty 4/10)) !NO SOLDERING!



----------- Beginning The Fan Mod ----------------- The Fan will ALWAYS run at 100% it cannot be changed unless you reattach the wire. While cooler temperatures are always good this does sacrifice battery life. This is all likelyhood voids your warranty use at your own risk. The fan will be significantly louder than normal and will likely be very noticeable.

You will need.

  • 1x Phillips Head screwdriver (that fits the Y510P screws)
  • 1x VERY SMALL flathead screwdriver
  • A dish to keep the screws
  • The assumption that you have some technical skills.


  • Remove the battery and charger
  • Carefully remove the bottom cover of the laptop
  • Remove the sticker to the right of the fan to access the area with the controller
  • Using the small flathead screwdriver lift up on small block at the end of the cable
  • carefully use the small screw driver to lift one of the clips that holds the BROWN wire
  • carefully and gently remove the brown wire from its casing (any more than a nudge is too much)
  • securely plug the block back where it came from following the natural curves of the cable.
  • Place the brown wire in a place where it will not create a circuit (behind the other larger connector)
  • * for added security you can tape the end of the cable to assure no accidental connections.
  • Without closing the bottom power on the laptop and give it 10 seconds if the fans do not turn on shut the laptop down
  • assure all of your connections are correct and reseat the plug to assure contact.

Now put a simple switch between the fan and the connector on the mobo and you can easily toggle full speed / auto fan control.

Someone already did create a loop however the loop was at best 5% successful and caused the fan to ramp up to full speed go for 10 seconds then drop to 0 RPM which bothered me immensely. Its far better to have the fan always run at full speed than it is to hear it constantly ramp up and down and have the brief period of no air movement.

Nice work. Simply cutting a wire often doesn't work on fans, so people looking to try this on other laptops should make sure they know how to reconnect the wire before trying. I vote for the switch idea.

Also seeing Fahrenheit is weird for PC temps, and yes I am American.

How would I go about implementing the switch idea? Got no experience with this sort of thing. I would need to do it on both my main fan and the fan for my Ultrabay GPU. It would be the brown wire for the second GPU too, right?

Why not create a macro on the dust removal tool to loop whilst playing games?

Yeah someone already wrote a script for this: Y510p Ultimate Cooling Mods Revealed...Unshroud yo... - Lenovo Community

It doesn't work. The laptop actually heats up more because of the long delay between fan cycles since it's 9 seconds @ 100%, 2 seconds idle, and so on. Constant fan at a lower RPM is actually a few degrees C cooler in my testing. I'd imagine constant full-blast would be even better.

I've already cut my bottom cover per the mod described in the linked thread, so my second GPU isn't hitting mid-90's and throttling any more. But it still goes up to almost 90C in PlanetSide 2 because of how damn hot it is here in California right now and I'd like to lower it even more by maxing out the fan speed.

Well then, I guess I could try this by wiring up a switch of some sort. I'm just trying to think where the best place to put it would be. I don't really want to create any unsightly holes in my laptop's case just for this.

You can also try http://forum.techinferno.com/lenovo-ibm/7358-ideafan-y510p.htm might be enough to start with to imagine if its worth introducing the switch and if it would help you in your case.

I tried it and it works pretty well. I think I'll use that program instead, because I don't really want to run the risk of ruining my main computer. I need this thing to last at least 3 years, so going in and removing wires probably isn't the best idea.

So if i understood this right, the brown wire controls the fan, and if it is disconnected it goes to 100% speed?

Is there a place on the laptop to mount a simple small switch for the PWM wire (preferably on the left side by the fan) and does anyone know if turning the PWM on and off would damage the fan?

i think this would damage the fan itself faster. better solution is using software ideafan, or you can buy cooling pad and overvolt the cooling pad. pc case fan also worth to try if you have 12V supply, they give more airflow than cooling pad.

      Hi,
       
      I need help in fixing my Thinkpad.

      I just got a T440p yesterday. It was working perfectly until the following:

      I reinstalled Windows and then I installed Vantage.

      I installed all the latest drivers.
      I also choose to install the bios update. The bios update ran in Windows and it asked me to restart. After restarting, the screen was blank. I tried powering it off and on and I saw the Thinkpad logo but after that the screen was blank.

      I tried powering on and off again and there's no Thinkpad logo now and the screen is just blank with the green power on. No sound, no nothing.


      Here's what I tried:
      Pressing the power button 10 times and then holding it for 30 seconds. Unplugged and battery is detachted Detached the CMOS battery and the reattached it Removed the ram, harddisk and optical disk drive. Attached the battery and inserted the charger. I turned it on and there was a couple of beeps Tried pressing FN+R and created a bootable USB I'd like to ask: How do I fix this? What do I need to do?
      Can I reflash the bios in some other way? Do I need to buy a new motherboard? Will this solve the issue? It's my first thinkpad and I'm really excited but I was bummed out that this happened. Can you please help me?

      Thanks in advance!

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!

      Hi
       
      Currently I am using Nvidia 376.44 version for SLI functionality. On trying to install any higher version , SLI wont function & only 1 card works.
       
      if anyone is using higher version Than the one mentioned above for SLI, please let me know
       
      Thank You

      To install the unlocked bios, I prepared and booted a freedos usb. I start the installation by typing flash.bat but every time I get the following error: Error 28: Protected Range Registers are currently set by BIOS, preventing flash Access. Please contact the target System BIOS vendor for an option to disable Protected Range Registers.
      How can i solve this problem ?
