Re: [coreboot] Lenovo T420 Question

[i1w5d7gf38keg]

The temperature difference get bigger when the temperature rise.
I recommend the Thermal Grizzly "Kryonaut" over the GC-extreme. The price didnt 
matter that much in such cases. I for myself use 5g in about 5 years. "I" think 
Thermal Grizzly "Kryonaut" is better. 
If i get 5 oder 10g for 15euro - does not really matter.

It would be nice now to see if our information could help drop the temperature 
on a quadcore usage inside of the T420.

Re: [coreboot] Lenovo T420 Question

This test here show the opposite:
http://extreme.pcgameshardware.de/attachments/831791d1434218266-review-thermal-grizzly-kryonaut-hydronaut-auswertung.jpg

The Gelid GC-Extreme is not as good as Thermal Grizzly Kryonaut also listed by 
this test here:
http://overclocking.guide/wp-content/uploads/2015/06/Tim_test_update1.png

and also some other tests i had read.

I dont know where you got this test you paste the results. I have never seen a 
test result where the GC-extreme was better then the Thermal Grizzly Kryonaut 
before.

5,55gramm of the Thermal Grizzly Kryonaut cost about 15€. I dont think that you 
should go there for the best price. You apply it once and 5,55g is really much 
for a normal user. You would probably have enough for years.

Re: [coreboot] Lenovo T420 Question

[qma ster]

Actually there is an even better non-conductive thermal paste (not liquid
metal) than "Grizzly" --- it is called " Gelid GC-Extreme ". Here is a
comparison from one review website that I screenshotted -
https://s4.postimg.org/qvp326pjx/Thermal_Grease.png  . The difference
between them is not big, but I think in your case every degree counts.
Also, there is a packaging of Gelid GC-Extreme that is 10g -
http://gelidsolutions.com/thermal-solutions/thermal-compound-gc-extreme-10g/
, this larger packaging gives a very affordable price per 1g and will last
for a long time ;)

Re: [coreboot] Lenovo T420 Question

[i1w5d7gf38keg]

You can install a quadcore. 2720QM is been tested working. 
http://forum.notebookreview.com/threads/t420-upgrade-to-i7-2720qm-es-q154-successful.624256

The probably fastest CPU that the T420 could get cooled is the Core i7-2860QM 
(45W TDP). 

Official dualcore CPUs have a TDP of 35W.
Those inofficial working quadcore CPUs have a TDP of 45W. 
The minimal requirement to get those quadcore CPUs working is to apply the very 
best thermal paste you can get for money. At the moment this is the "Thermal 
Grizzly Kryonaut". Otherwise your CPU would start overheating and throttling 
when you use for example a old and inefficient Arctic Silver 5.

Untested/unknown: If a ivy bridge CPU would work. The OEM bios didn't had 
support for those.

[coreboot] Lenovo T420 Question

[Gee Elle]

Hello All,

 I have a question for people running coreboot on T420

Can you please suggest the fastest CPU i can upgrade to without too many heat 
issues ?


i can use more powerful ( 90W  i think ) power brick if needed ..


thank you everyone.
