XPS 8950, CPU fan pin headers on motherboard

Question

I plan to install an aftermarket CPU cooler in an XPS 8950. Specifically BeQuiet Dark Rock TF2 based on this writeup:

https://www.dell.com/community/XPS-Desktops/XPS-8950-aftermarket-CPU-Cooler-Be-Quiet-TF2-fits/td-p/8152513/page/3

I am curious if the CPU fan motherboard pin connectors are a standard wiring that would accept the aftermarket fan as-is. I have seen many older posts with information about Dell motherboards using a proprietary swapping of pinouts.

Since the linked post was pretty thorough and did not mention it, my guess would be that these are standard wiring. But I want to ask before I get into it for further assurance (or to first be prepared with an adapter).

While I'm asking, what about the case fan pin headers?

Thanks much in advance!

standard pwm 4 pin, but dell bios checks fan tach rpm and may or may not give a boot up error if fan rpm differs too much from oem fan.

same for case fan header

Yes you can press a key to continue to boot. It is just Dell bios did not know you swapped fan and thought the stock fan had gone bad.  The error is a warning only.

Thank you.  Is this an error that I can just acknowledge and continue to boot sequence?  Or better yet re-baseline in the bios?
