No, you cannot fit a Xeon E5-26XX v4 CPU into an E5-26XX v3 socket. The socket types are different and not compatible.

I have a Lenovo ThinkServer RD350 equipped with an E5-2630 v3 processor. Inquiries: Is it possible to install a V4 CPU in a V3 server? Both models share the same socket (LGA2011-v3), but will a BIOS update be necessary? The current CPU draws 85W, so can a 135W model fit? Specifically, an E5-2698 v4 or similar? The product listing claims support up to 105W, but I'm unsure if that applies to all configurations or just the available MOS. Here are the exact details:

I've attached the relevant pages for your review.
It varies by BIOS version, and OEMs might add unusual restrictions. Unless tested, you'd need to verify. It should handle v4 CPUs thanks to the C610 chipset, which matches both Haswell and Broadwell 2011-3 chips. Power-wise, it seems feasible if the board supports 135W, giving some room for heat. The thermal design likely accounts for this, so newer Xeons might still run cool. If the CPU is costly, opt for the cheapest v4 model and see if it works.
Be mindful of more than just chipset compatibility; Lenovo could impose additional restrictions. Let me know how I came to this. I believe you shouldn't go beyond 105W, since that's probably the limit for your motherboard and power supplies. NOTE: @tJuggernaut29 You might have missed something—there’s another page on the site mentioning specs for a v4 model. Updated in 2018, it could apply to newer versions of this product. It’s not as clear-cut as what I discovered for the M71E I own, though there are some useful details if you search further. Edited October 25, 2022 by An0maly_76 Revised, more info
Reviewed the Processor Options for the v4 release. It doesn’t go that high (maximum E5-2660 v4), meaning you can use a v4 chip but not the one you prefer. Unless you can find a cheaper option, it might not be worth trying unless the processor is affordable. The 2660 model looks solid.
I understand your feedback about limiting the speed to 105W max. I’ve ordered an E5-2660 v4 used from Amazon and plan to arrive next week, updating on the results. I’m also considering a second heatsink and fans to support dual CPU operation, as it’s compatible. I’ll keep you posted on the CPU upgrade progress first.
Received the E5-2660 v4 CPU, but it didn't function properly on the Lenovo RD350 v3 server. Placed an order for the E5-2660 v3 and it's working perfectly now.
Have you checked for an update? Your bios is currently at version 1.33, and the changelog shows broadwell support wasn't added until version 3.32. You can find more details on the Lenovo support page. I’m in the same situation as you—wanting to ask before upgrading to a v4 processor when it didn’t work.
I purchased an e5-2660 v4 to test it out, and it functions properly. I think just updating the BIOS would be enough. I’m sharing this so others in similar situations can help.
