hamluis, with all due respect to you because you've been into this far longer than myself, I don't believe this is overblown & only ask for the chance to plead my case. One important part of what you've stated above, for the prior 72 hours pre-purchase, at times drifting off sitting at my desk & with a total of about 9-10 hours of sleep while researching during the stated period, now headed towards 96 hours to verify the results again, feel that I've put more time into this decision than any other since the beginning of the build. Surely more so than any physician would deem healthy for me (or anyone), yet that's the way I was on the job prior to becoming disabled nearly 11 years ago, putting in 16-18 hour workdays, gaining promotions along the way. My hope is that like when working, that the sacrifice leads towards meeting my goal. Having a PC that'll compete w/out thermal throttling, which costs me huge on sites like HWBOT, where the only requirement is having the Intel Extreme Tuning Utility installed, bench & upload results. Which is a site promoted by Intel for competing, they don't advertise, don't want nor accept donations, just wants Intel owners to dive in & have fun, and I'm one of the gang.
..all you have to do is look for info on such.
That's precisely what I've done, and have been doing, ever since beginning this build months ago......it's actually an extension of another Topic created months ago linked above, where I asked a question on a couple of key items on a vital component, gave as much info as I had researched long & hard for, gave time for anyone to answer & thanked the ones who read it. I also felt that by asking in the Internal Hardware forum, this would draw a fair amount of responses faster than on the Linux one, where I began the discussion. If anyone read that Topic linked, especially the first few pages, it's clearly seen that I spent quite some time.....and a vast amount of resources that took me three years to save towards each & every month, and still do The components I chose where the best that I could afford for my income level.....and certainly more intelligent than the decision I made in the year 2013, where I purchased a XPS 8700 that's Dell's 'flagship'....for lack of words that I cannot speak here, PC. It's far off that mark & I wanted better than the scraps off the bones that were thrown at me this go around, and realized to do so, must build it myself.
The XPS 8700 could have been a great PC, were it not for a couple of shortcomings, the first & main of which shipped with an i7-4770, still to this day a Top 10 common CPU on Passmark, yet Dell starved it for power by providing only a single 4 pin power socket, rather than the standard two. Installing the i7-4790K purchased early in fear of price hikes should supply get low made this stand out even more, the occasional freezes already ongoing (no BSOD, the screen totally frozen as seen & no errors were found than sudden shutdown) increased to quite more frequent ones, even with UEFI firmware upgrades to address the issues. The other, a fake PCIe x4 socket, physically yes, electrically an oversized x1. At that point, I realized that I could do better myself, with research, and no I don't have an engineering degree in IT, just an enthusiast with the will to do better, and overcome the shortcomings or bottlenecks of OEM units.
This isn't like I asked 'should t substitute 99 cent 9 volt batteries in my smoke & CO detectors over the approved/rated models?', where the answer is most definitely certain. Only in a dire emergency should one do this, until the proper model can be found ASAP....within 24-72 hours. Common sense would dictate to most to keep replacements on hand, as these sealed batteries has a long shelf life. Components such as what I'm asking about (other than the MX-4 thermal paste I'm stocked up on) are not typically stocked up just to have spares unless a system builder, it's a major purchase for a consumer.
That's not the type of question I'm asking. In fact, there are numerous complaints in regards to quality of components (CPU coolers) I've asked about, and why I didn't rush out and grab a $24.99 model on promo with $5 off or a $10 rebate, or w/out any incentives, because I actually read reviews of what I purchase before pulling the trigger. Though I will admit, it was a mistake in not asking directly during the build, though did ask for suggestions & input, no one responded to the Topic as to what I may had overlooked.....and I welcomed all input. I simply incorrectly assumed that Intel wouldn't send out a piece of garbage with a 'flagship' 1150 CPU, mainly because it was the first new one I've seen with a copper core, albeit sort of hollow.
Back to the complaints of 'budget' coolers, the list goes on & on, noisy & rattling fans or doesn't work at all, low quality mounts with vibration (what one doesn't want in a MB that's standing vertical) with a small sheet of instructions printed in a dozen languages that requires a magnifying glass to read, no disrespect intended to international market. The instructions should be localized for the intended target area with larger & clear print, easy to read & understand, and not leaving out parts of to be guessed at. After reading all of the complaints & shortcomings, wanted a better solution, one that would be inline with the rest of the build, and time after time, was pointed towards Noctua for quality, ease of install, long warranty, and clear/precise instructions on what to do to install the component. This is what I received with the Fractal Design Define R5, and I expect the same from Noctua.....a product that's worthy of placing their signature on.
As to any newer & better quality thermal paste choices, it's my hope that there are improvements, and will look into that further today. Arctic MX-4 is still a leading brand, as was MX-2 before then. No doubt there are other excellent choices, at the same time, there's those not fit for for some (or any) purposes. I also have some high quality thermal pads by 3M (bulk sheet, cut to fit), which I use when cleaning up notebooks, and place on the discrete GPU, if installed, and onboard, if covered with a heatsink. So far, so good. 3M has always had a decent reputation, though I'd not install this on a CPU.
'Budget' rated components were never considered for this build & have built another for myself since, using the CPU & RAM from the XPS 8700, will replace with a less power hungry CPU & have spare RAM modules when I'm ready to unbox it again. Not a priority for me at this time.
What is for now, has been stated, and it's my hope that the Noctua NH-D15S does live up to the standards of the rest of the build, my first & spent quite some time, carefully installing everything, with an emphasis on wiring management & build quality that I can place my signature on.
With all bases covered, I've rested my case, it's now time for me to get some quality rest.
