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 -

Re: [coreboot] Lenovo T420 Question

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

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. David. -- coreboot mailing list:
