Re: [coreboot] Lenovo T420 Question

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.

> From your 1st test, Grizzly is better by 0.33 C , and from your 2nd test - by 0.31 C. Even if your tests are more correct, 10g of GC-Extreme at my local market cost the same as 5,55g of Grizzly -- that means, Grizzly is almost twice more expensive per 1g ; that is too big price difference for just 0.3 C . BTW it took me just 1 year to spend the first 10g, so had to buy another 10g....

Here is a comparison from one review website that I screenshotted - >>> https://s4.postimg.org/qvp326pjx/Thermal_Grease.png%3E%3E%3E   . 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 ;)
