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:
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.
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!

If things don't go right:
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.
