Re: Y510p Ultimate Cooling Mods Revealed...Unshroud your cooling fans!

iok guys...well I own y510p and I`m car and computer tech ( nowadays they seem to go together ) It`s known that the Y series overheat and I want to put a watercooling on that but I`m waiting for the warranty to fall so... what else can we do for now?

Every fan which has controlled speed is controlled by one wire. Even in your cooling pad if it`s nicely made you should have 3 wires going to the fan or each fan. The laptop fan is not exception.

What you can do is just bypass one of the wires to a ground or + ( depending of the controlled method ) and put a potentiometer or a slider which controls the resistance ( controls the voltage input ) for that fan. What I mean and what you need to do this?

1. Om/voltage meter

2. Small wires (0,5-1cmx2) 10сm long

3. heat tubings ( make it like a pro ) - optional

4. solder gun ( make it like a pro ) - optional

With this mode you will put an external switch which  will be able to control the fan by hardware bypass.

So in order to understand how the three wires work first you need some mesurments.

In the Lenovo y510p the brown wire going to the fan is the controll one.

On the other two wires you have + and - volts

Imagine the current like a water flow. The water is going from plus to minus and moving throw the fan it does some work ( moving the fan ). If you put a third wire you can:

1. add more flow to the point of action ( the fan) or

2. take some of the flow so less work is done.

So how to do this mode:

1. Open up the laptop back cover and ger axcess to the fan wires

2. Measure the wires with the voltmeter so to learn which wire is + and which -

3. The third wire should be +or - depending from the control method

In overall there will be 2 wires positive one negative or 2 wires negative and one positive.

4. Now load the laptop so that the fan starts spinning faster.

5. Measure which wire changes the volt imput or on which wire the Voltage fluxate.

6. Install a potentiometer on that wire with your wire in T shaped method. put a diod therre as well so no current will go to the motherboard from your new wire and a diod to your new wire. ( in this mode the laptop and you both are going to control the fan ) Connect your wire to the +/- ( depends from the polarity of the wire that fluxates) Now you are done.

7. Install the switch where you decide on the corpus and close the laptop.

IF WHEN YOU MEASURE the 3 wires they show you constant voltage what the case is - that the 3rd wire controls the resistance 

In that case your job is the same. 

If you take out the brown wire the fan will spin at full throttle on the y510p.

So in this case you just need to  1.cut the wire put a potentiomet there and conect your new wire to the potentiometer and to the + or - depending on the polarity. You are done.

Write me if you don`t understand something or it sounds sily to you.

It`s really very simple. I can explain it in details and put schematics, but I`m too lazy Smiley Happy

Best regards and hope you are satisfied.

That is the ultimate fan control mode

Re: Y510p Ultimate Cooling Mods Revealed...Unshroud your cooling fans!

i just accidentally broke my brown wire.. haha my fan is running full speed 24-7 now..

 

it's a little annoying but the laptop is a little cooler now!..

 

i'm thinking to try to put the brown wire back into the extremely tiny little white plastic piece that was connected to the motherboard.. but it's sooo tiny i don't see how i can do it!

try to get out as much as you can from the white pin so you have enough space to work and use a needle to put the wire back Smiley Happy Good luck.

Re: Y510p Ultimate Cooling Mods Revealed...Unshroud your cooling fans!

First of all, thanks for posting this. It helped a lot just doing the SLI card fan. I just have one question: is it OK to cut the foil on the main CPU/GPU fan? It covers some of the plastic that needs to be cut off.

Well....if you had the single GT card....it was going to be ok, but now...

If you cut that foil you will damage the second GT working in SLI after 1 month. The second GT works around 900hours with that foil off. Good luck

Don't worry Smiley Wink I didn't cut it for that exact fear. Thanks for confirmation.

Hallo guys just wanna let you know that i've tried using ideafan from this forum .. http://forum.techinferno.com/lenovo-ibm/7358-ideafan-y510p.html

and i worked pretty good for me.. 

now i'm making my custom cooling pad from old desktop fan using 12v adaptor and try to channel it directly below the ventilation holes.. and just wanna ask u guys is the ventilated hole for the ram modules intakes or exhaust vent? thanks alot for ur help.. stil a noob.. Smiley Happy

My temps still suck... getting about 60C idle here.. It's ridiculous. Fan noise is so annoying and I am just so sick of this crap.

 

Here is a thread I made about opening up the laptop and replacing the thermal paste

with new Arctic Cooling Silver 5 paste. It made absolutely ZERO difference whatsoever.

 

Really disappointed Lenovo. You guys need to focus on quietness and cooling way more in the future.
