hello all
i have started modding my L420.. absolutely love this machine it keeps up with my new l480 thinkpad that has a 8th gen intel cpu...
i was going to go with the i7-2630QM , 4 core 8 thread cpu which is a 45 w TDP
the machine comes with a i5 35W TDP.. i have been reading and alot of people have done the 45w I7-2630 QM mod and temps have been ok.
im thinking of going for a 55W TDP i7-2920XM it has a faster clock rate and a bigger cache ...
i will buy the L412 heatsink and fan apparently it is larger.
i going to add a extra fan within the other board and add a extra external fan/blower on the outside of the case ( sunon mighty mini),
im wondering if anyone has ever done a 55w CPU in a 35w tdp rated laptop.
also wondering if anyone has come across a fan that fits in the express card slot.

Re: L420 Modding questions
I can't answer about mucho of what You asked. But is it worth it to put the 2920 ? Is the performance that mucho better?

Who needs another toaster?
Maybe the larger L520 can handle it, but it will be way too hot in the smaller L420.
Instead of thermal paste, use a Honeywell PTM7950 thermal pad.

Re: L420 Modding questions
Not a good idea IMO. The TDP of the 2920XM is 57% higher than a 35w dual-core i5, the actual max power consumption will be much higher. Most likely outcome: you won't be able to make use of its full potential because it overheats like heck, even with the added fans.
Stick to the 45w
