Also worth noting, this system is running a very mild overclock of 3.9GHz across all cores (Turbo core sync). While overclocking is nice, I don't find it as necessary in this application as it is in a dedicated gaming rig. In this situation, I imagine those 12 logical cores are going to pay higher dividends.
Currently the H110 that is cooling things is more than adequately in my experience. One of the unit's fans starting having trouble so I unplugged it. While of course this did affect cooling performance I found that the CPU still remained within acceptable ranges.
I do understand that having a larger, more capable cooler could potentially allow the system to run passively but I see a couple drawbacks with that. Without leveraging the CPU fan failure shutdown feature, the system would either continue to run at elevated temperatures or would eventually shut down due to thermals. Neither seem very good for the hardware. While this system is meant to be high availability, it is not critical to any revenue-generating function so downtimes are acceptable.
In summary, I don't know that I really need something that's at the upper limit of cooling performance based on the fact I don't know that the CPU throws enough heat to warrant one, noise is of zero concern, and I don't wish to have a passive failover method.

I think your approach is absolutely right on when the topic is a server. Most small business class servers and higher have features to maximize uptime and error-free operation (redundant PSU, ECC memory, UPS, etc.).
For me, if the server goes down then it's down until I figure out what happened to it. The current iteration of this box is basically a glorified redundant data server with some media usage sprinkled in. With X79 I'm looking to tinker with VMs and expand the media serving functions. In other words, if the device is no longer available, personal files won't be accessible and some folks are going to have to find something else to watch or listen to. In the event of a catastrophic failure, the entire data structure is accessible on backup devices. Very minimal impact.
I agree that spending more on a cooler, so long as the manufacturer is known for keeping up with sockets, makes more sense than spending a little extra on something like a graphics card. I remember when the NH-D14 came out. That was back when I was thin, young, and vibrant
I was surprised to see it as a recommendation in this thread on the basis that it was even still viable.
psyclum has summed it up quite well.
A good cooler is like a good case. It can be used for many many years.
The Define R5 is a great case, but the stock fans in front are sadly lacking in performance. Replacing them with something better and higher speed rating and using motherboard temp/speed control means if a fan does fail and heat starts to rise the speed of other fans is increased. End result is system stays cool and we hear more noise from case .. meaning it's time to investigate why.
"Ways to Better Cooling" thread linked in my sig might be of interest. 1st post is index, click on topic of interest to see it. 5th is a good basic guide to case airflow, 4th is PWM control of case fans, 48th is Define R2 -R5 case mods.
As for fan redundancy, using a 2x fan cooler or a semi-passive cooler like the Thermalright 140mm fan Macho coolers gives you a fan on cooler that sets very close to rear exhaust .. meaning case airflow 'semi-passively' moving through the cooler keeps things cool. I have used Thermalright HR-22, Le Grand Macho, Macho rev.A & B, Macho Direct, etc. All work very well. Le Grand Macho is one of the best passive / semi-passive, but Macho rev.A & B are close. While HR-22 is biggest with most heatpipes, the Le Grand Macho seems to slightly outperform it. Macho Direct is lower price but does an amazing job. I only mention these because they are offset back and end up flowing air even without cooler fan/s.
CPU cooler mount patterns (knock on wood) seem to be rather constant for many years now. But most good cooler companies have traditionally supplied mounts when cooler mounting changes were needed. Some do it free while some sell them. Either way it's not expensive.
Honestly, 2x front and 1x bottom intakes with case raised so bottom vents get better airflow and no exhaust fans needed. Remove the bottom and back grills and not only does airflow increase, but noise levels go even lower. With the bottom filter sliding out the front and front filter accessed by opening the front door of Define R5, it is super easy to keep them cleaned and in a smoke free house there is almost no dirt buildup inside of case.
As for what fans to use, there are many. Thermalright TY-147A is coming out in a square version soon, new F D Venturi look to be good, Phanteks PH-F140XP, PH-F140SP and PH-F140MP are good, Noctua are good but more expensive in most places, .. and that's only a few of what I consider very good.
Edit: Define R5 has 180mm CPU clearance. This is 188mm surface of motherboard to side cover. 40mm Ripjaw RAM plus 3mm RAM socket is 43mm leaving 143mm for fan between top of RAM and case. (29th post in 'Ways to Better Cooling'
