170 W 8.5 A is not enough

Hi, recently I was able to buy the maximally equipped W520, I have a problem with it though. It's about power supply when working with a docking station, the laptop claims that the power supply is too weak and suggests switching to the one purchased with it. Of course it works with the original powe...

Re: W520 CPU cooling swap

That's interesting already, my CPU newer drops lower than 2,6GHz and goes up to 4,6GHz on single thread loads. I cant wait to do more tests.

Re: W520 CPU cooling swap

Ok maybe I will buy this 04W1574 and make few tests to settle this once and for all.
What tests you propose ?

Will I need something more, I have thermal grease tg5 of course
, but I mean thermal pads maybe ? If so what size ?

Re: W520 CPU cooling swap

That's interesting, I have the same CPU/GPU configuration and the seems that the same temperatures on officially 45W TDP. I have 96's during renders in 3d Studio etc. So I thing there is no real difference between 45 and 55 W heatsink. Maybe when Intel introduced 55W CPU's, they tested old cooling s...

Re: W520 CPU cooling swap

Thanks for you reply. Well You are absolutely right, I don't see any difference between FRU 04W1574, 04W1575 and what I have. I wonder if that's scam like with 4338 USB 3.0 docking station. Only difference I see is between 04W1574, 04W1575 and 04W0437 - this one has much more massive bases, but VRAM...

Hi, I just bought my W520, and I decided to upgrade it every possible way. Everything went good, but I have problem with CPU cooling. I have 04W1576 (45W TDP) unit which works fine, but up to 96*C. I decided to buy 55W TDP unit, but only one I was able to get right away in Poland was 04W0437. Ok U m...
