Hello wizards; I am a novice and I seek your guidance.

My machine is a mostly stock Dell 8940; it came with i7 10700 2.9ghz, 8gb RAM, Nvidia GeForce GTX 1660 Ti 6GB - I just added a spare RAM stick to make it 16gb RAM total.
I want to to upgrade the CPU so that the base clock truly is no less than 3.4ghz and I've identified the i7 11700k 3.6ghz as a possibility - given that both CPUs use the same LGA1200 socket for my Dell's H470 chipset.
The question is, will this single change be too much for my PSU, or could it do some other damage to that stock XPS build, which in either case will lead to power-offs and a reduction of the PC to dust? The PSU is 'Model L360EBM-00', or 'Dell P/N 2VDOG', so I'm guessing 360watts.
I admit my reasons for the upgrade are odd. Battlefield 2 is a 2005 title which has mods supporting up to 64 ai players, but it only uses one core. So you can have the most powerful GPU and plenty of RAM but if the base clock speed of the processor is below say 3.4ghz, expect slideshow city when all 64 players are engaged on a close quarters combat map. A few years back my old PC had an i7 4790, a humble thing today but it had 3.6ghz base clock and handled Bf2 with ease. So it's a frustrating mistake I've made assuming that this newer Dell could do better without checking a simple thing like base clock. But perhaps an upgrade is possible rather than buying a whole new machine. Please do let me know your thoughts!

Kind regards,
Mark
 
Well I went ahead and installed that larger cooler as advised and I'm glad I did! The machine's definitely cooler now and near silent. Beforehand there was a whir when the machine was on and during Bf2 or similar heavy work, a louder whir. Have tried Bf2 now on the most troublesome maps and... no whir :D Still a drop in fps during the really intense firefights, but not as bad as before. So I think I'll accept that. Looking back on my previous PC, the one with the 4790, maybe that was indeed the perfect CPU for a single-core hog game; but it only lasted about 2 years before it conked out - maybe I ran it into the ground without thinking.
Thanks again to all posters - I'm glad I checked in here before trying something foolish!

Glad it's sorted. Happy gaming :)
