Latitude E5420 CPU and GPU Upgrade
Hi all,
very new to this so go easy on me! I’m trying to upgrade the CPU and GPU (amongst others) in my Dell Latitude E5420 to make it run a bit better. I’m currently running
CPU: Intel(R) i3-2310M
GPU: Intel(R) HD Graphics 3000
im wanting to put in an Intel i9-9900k processor in along with a better GPU. I’ve heard there can be some difficulty with doing this, just want to know if it’s possible, or if there’s anything I should be thinking about when I’m doing this? I’m planning to get a cooling pad as I know the i9 runs quite hot, and my RAM and HDD have already been upgraded.
cheers,
matt

CPU upgrade is possible - though ONLY to the same generation of CPU (i.e., second) you now have. So - absolutely no to your proposed i9, which is in any event a desktop CPU - it won't work in your notebook.
Just about all Intel mobile CPUs starting with the fourth generation must be soldered to the mainboard. Even the third-generation (Ivy Bridge),though socketed are unlikely to work in your system.
Your integrated GPU (intel 3000) is common to all second-generation CPUs so there's no upgrade there.

@ejn63 thanks for your response. So I couldn’t go any better than an Intel i7 2___, is that correct?

Correct -- and 35W or lower total design power. There are 45W CPUs - don't even think of trying one of those; the system will not cool itself adequately.

@ejn63 Thanks again for the response. Would using a cooling pad or upgrading the CPU fan enable me to use a 45W CPU as opposed to a 35W?

Unlikely. There's no guarantee the system will even boot with a 45W CPU - and it's not just heat, but the fact that the system board's voltage regulators aren't designed to work with a CPU that uses upward of 30% more power than the ones they're designed for. And even if the system does power up, you have aged VRMs - the added power demands will push them over the edge to oblivion in short order.

Welcome to the Dell Community @MattMac99
I have been upgrading and selling E6420XFR's for over 5 years.
The CPU's I use are the Core i7-2640M and the Core i7-2720QM (QuadCore 45W TDP)
With the (45W TDP) CPU the fan does run a little more often when usual and the battery does not last as long due to the extra (10W TDP).
But I have never had a return or question due to overheating.
Best regards,
U2
NOTE:
There are 2 Extreme CPU's (55W TDP) that are compatible but I have never tried/tested them.
