the E6x00, E6x10, and E6x20 are completely different generations of the 
Core I processors and chipsets.   The x can be 4 (14") or 5 (15").  so a 
E6520 and E6420 are nearly identical.

the -00 were Core 2 Duo processors, with GM45 chipset.
-10 were i5/i7 1st gen (3 digit) with QM57 chipset
-20 were i3/i5/i7 2nd gen 2xxx with QM67 chipset
-30 were i3/i5/i7 3rd gen 3xxx with QM77 chipset
-40 are i3/i5/i7 4th gen 4xxx with QM87 chipset (these are current 

each of these has a different set of choices for graphics, wifi, 
bluetooth, etc.

so, no, what does or doesn't work on a E6500 has little to do with what 
will or won't work on a E6420.

that said, these are very mainstream business laptops, I'd expect C7 to 
mostly work with them.

I had C6 running on a lot of Latitude E6500 laptops and I now have C7 on all of them, and I do
not have any complaints on overheating. In fact, I get no complaints at all on the laptop, apart from being heavy.
I never had that on any laptop running Centos, and I have about 7 different models in use, Acer and Dell.

I'm  now working on a Latitude E6320. Yesterday, when burning a dvd, it became a bit warm, but no real issues.
No experience with E6420 though, sorry.

Greetings, Johan
