High CPU temps on new AIO build

I believe I'll probably pick up a Noctua 40mm fan, question is what's the preference/difference between these two or is there a better option?

Amazon.com: noctua nf-a4x20 pwm

One is a 5V version, other looks std, both PWN 4 pin, not sure the benefits or if either will work.
I wonder that also, recently accidentally ordered a 5V one for my XeonD system. It works fine, but my expectation that it would be less noisy is not true - or its not pwm controlled after all, at least it never turns down. Have not delved deeper since the board is still on the bench and real life catched up...

@whitey - I have a broken (BIOS is flaky) X10SL7 if you need it for parts, testing, etc. Yours for the cost of shipping.
Thanks for the offer, all seems calm on the home-front once I added the 40mm Noctua cooler, probably need to find a better way to attach but for now simply setting on top and blowing down is doing the trick, came down to my least desirable solution, which is more of a band-aid fix but I don't have time to mess with this anymore.

Thanks all for the great input and rapid response!
