Re: Solution to W520 CPU and GPU overheating and GPU down-throttling

Folding as in Folding@Home. It stresses both the CPU and GPU pretty heavily.

How high a turbo can your system sustain under load? Mine will end up around 2.55GHz-2.6GHz after a while of running Folding@Home.

@Colonel - Thanks for your numbers.

 

I'm not sure I want to install folding. However, when I run the Fritz chess benchmark, which runs the CPU at 100% on all 8 threads non-stop, my system sustains 2.6 - 2.7 ghz with a max core temp of 79 C.

 

As @lei points out, CPU cooling seems to be about the same with the 04W1576 vs. 04W1574, wheras GPU cooling appears better with the 04W1574. I'm not too concerned about the GPU, as my work is CPU but not GPU intensive.

 

I'm a little suprised that my 2720QM doesn't sustain 3.0 ghz at 79 degrees C or less.

- If your laptop is still under warranty, call Lenovo and ask them to replace and reseat the heatsink + fan. When the technian arrives ask him to use a high-quality thermal paste and not the crap that comes attached with a new heatsink unit.

 


 

First of all, thanks for your information,

 

I also own a W520 which keeps getting very hot, since my laptop is still under warranty i asked Lenovo to replace the fan so they did, my old fan was a 04W1576 and they replaced it with a new 04W1576. I was not convinced they did a really good job so i tested the temperatures again and the cpu and gpu temperatures were about the same before i sended it to lenovo (CPU=86C & GPU=96C).

After this i sended the W520 back to lenovo and complained their solution did not change anything, they said we will replace the CPU (which would not solve my GPU problems but okay). After a week i talked to them by phone, i had to pay the new fan and maintance costs of 96 Euro's (96 only for maintance). They told me my laptop was not desigened to have the 55W cooling fan and that the device was designed to handle those temperatures.

I told them to send my laptop back without any changes.

 

Can you confirm that the 04W1574 will fit my W520?

Machine= 4282 subtype=AJ9

CPU= Intel I7 2630qm

GPU= Quadro 1000M

 

Or do you have any other suggestions?

 

Thanks in advance

The 04W1574 should fit; it's probably marked as for the i7-29x0XM chip only on their database though.

What are you stress testing with, and where are you reading the numbers from?

I have monitored with openhardwaremonitor and intelburntest.

Also games like farcry 3 pushes this laptop to the max.

Re: Solution to W520 CPU and GPU overheating and GPU down-throttling

Hello, this might be late but I hope you can appreciate this information.

 

I recently bought the 04W1574 (manufactured in 2014) directly from IBM for a similar W520 (only difference would be that my CPU is the 2720QM) because I too was fed up with the temperature problems.

 

The thing is, it just does not fit. It seems that it is only designed for Quadro 2000M chips. As with the Quadro 1000M, there is not enough contact with the heatsink, meaning there is space between the copper and the die. The quadro 2000M seems to have a "taller" die.

 

The fan, as far as I could make out, is EXACTLY the same as in my 04W1574 from 2011. There is no difference. The model number is exactly the same. I only switched the fan to see if it fared better, and there is just no difference in cooling ability.

 

In conclusion: Be aware that the 04W1574 seems to only fit the Quadro 2000M. Also, in my case the fan seems to be exactly the same as on the 04W1576. I would advise against making blanket recommendations to everyone with a W520, because the configurations vary so much.

I would also like to thank everyone here on the forum for providing their solutions. My W520 with a 2630QM and a Quadro 2000M also quickly went to 90°+ GPU temperatures under load which, of course, also led to unbearable throttling. Luckily, cleaning the fan (which was partially blocked) and replacing the heaps of old, crumbled thermal compound (used Arctic Silver 5 there) was enough for me, temperatures went down by over 20°. I wish everyone good luck and would like to point to this disassembly video again: https://www.youtube.com/watch?v=CPGvKNuapzY.

I'm coming in late to the conversation as well.  Anwyay, I'm not sure about the height of the GPUs, but from a photo I took top-down I can see that the 2000M has a larger lid/contact area.  Also, the 45W has a 6-pin fan connector, while the 55W has a 4-pin connector, presumably to prevent installation of a 45W heatsink on a motherboard requiiring 55W cooling.

 

I just attempted to replace a broken 1000M motherboard with a 2000M motherboard, still using the original 45W heatsink.  Apart from the fan connector it installed fine.  It seems to sit fine.  I was able to tighten the screws over the CPU and GPU fine, but I can't see whether contact is OK.  Also there is some black plastic material on the heatsink around the contact areas.  It's possible that the opening on the 45W cooler is smaller than that on the 55W cooler.  I wish I had taken a photo before installing.

 

So I'm now pondering what to do.  I've got the heatsink installed, but unable to connect the fan, and not really wanting to spend another $100 for a new heatsink.  Ugh.
