Y500/Y510P spring mod with spacer guide

Hi!

edit: merged with Conscriptvirus's post from TI, so it's easier to follow:

This modification is very dangerous, can lead to broken chips.
Don't say i didn't warned you...

edit: he's right, it is easy


Lenovo did a sloppy job with cooler, too much thermal paste, weak springs, overheating and throttling machines...

First of all, disassemble the machine.
Then do a repaste, with bare minimum amount of thermal paste, and remove cooler again, check thermal paste spread.

Remove screws from cooler, by removing little plastik washers, keeping the screws to fall out.

My gpu heatsink was not paralllel to motherboard, so the corner without screw was slightly bended upwards.
Twist the gpu heatsink, so that corner is pushing gap pad a little bit harder. Be very gentle, you dont want to broke your heatsink.
You can check level by putting your heatsink on flat surface with gpu screws removed, cpu screws stays in place for now.

Then place a 0,5mm spacer under the spring like seen on the following pictures

These are screw number 4 and 5.
Screw number 6 is using a weak spring, so use double spacer, or change it to a stronger spring:
edit: removed picture due to limit

Put back plastik spacer, so screw stay in place.

Do the same process with cpu heatsink.
You can do this to ultrabay as well, but take extra caution, since there is no backplate, and it can lead to warped/broken board.

Lastly change the gap pad over cpu vrm area, because it is too tick, I used 0,5mm piece:


Aaand it's done!
Put back heatsink, use as little amount of thermal paste as possible, and enjoy 10-15+ lower temperatures.

Spacers was lying around, i had the spring from some old heatsink, so dont have exact types and diameters,
but Conscriptvirus did the mod also, his mod is better to look at, spacer perfectly fit into heatsink holes

edit:
I also did cpu mod, ended up adding a washer to screw 6, despite of changed spring, gained 1C-3C.
I can run XTU stress test under 85C with -95mV and 3,4Ghz 4core.
GPU and CPU idle is under 50, without notebook stand with fans.

Thanks to Conscriptvirus for his effort and pictures.:thumbsup:

If it worth to be sticky, Mods, please make it one.

Regards

 

Hey thanks for the guide. I want to try this soon, but I need to source a new gap pad. Do you have a link for what you ordered?

 

Phobya XT 0.5mm gap pad 7W/mk
Any 0.5mm is good, try to find the best for your needs.

 

, threads like this makes me wish I was even somewhat tech savy. I'm very dissapointed with my Y510p as it is severely gimped by overheating.
