New rig and new to overclocking. Guidance please!

[Chnjab]

Hello fellow overclockers! I'm some what new to overclocking and obviously new to this forum. I recently built a new machine that is for primarily personal(4K video editing & gaming) and also some work use. The relevant components are as follows.......
MSI Z170A XPOWER Gaming Titanium Edition, unlocked i7-6700 (Vietnam), 32MB Corsair Vengance LPX 3200 (4x8), 2 MSI GeForce 960 Gaming 4GB, 2 512 Samsung 950 PRO M2 in raid 0, 1 Samsung 1TB 850 PRO providing a daily bootable raid 0 copy using Casper, an NZXT Phantom 530, a Corsair HI100GTX with 2 Coolermaster jetflows pushing and another 2 pulling plus an additional 7 jetflow case fans(1 out, 6 in) operating on bios generated fan curves using CPU Package temp, also a Corsair ram cooler, an EVGA Supernova 650 GS, and 3 Dell 27" curved screens.
After a week or so of diligent trial and terror I have arrived at the following over clocking set-up which appears stable after benchmarking(XTU,CPUID primarily), limited stress testing(CPUID 100% continuous cpu usage for 4 hours), some gaming, and video editing.
102.25 base clock 48 cpu multiplier 46 ring multiplier resulting in 49.1MHz CPU, 47.1MHz cache @ 1.415 adaptive and XMP enabled resulting in 3276MHz linked. Throughout benchmarking and stressing maximum temp seen has been 73C while the 4 hour stress test resulted in a rock steady 69C. Maximum voltage seen with adaptive has been 1.424 extremely occasionally for a split second. I should add that XTU reports approximately .004 less voltage as does the as functioning indications in bios. I'm aware manipulation of the base clock seems to viewed by some as not typical however after testing many combinations doing so allowed the significant increase of the cache frequency and increases in benchmarking results.
I'm very interested and welcome all input and opinions of the results achieved, the predicted stability in a 24/7 system, and any suggestions on how to achieve more or better. I've seen the use of non OEM bios (H.O.T.) mentioned in other forums and on other sites and wondered if others have seen success through its use and where to obtain. Thanks for any input offered, Chris

Hi Chris, welcome to the Forum!

Ok, I do have a few questions about your build. First off, that's a lot of fans. Why so many? I can only imagine that it gets loud?

Second point, that voltage. Way higher than I would ever want to be using, especially on a 24/7 OC. Also, using adaptive voltage is allowing some major spikes to happen.

Thank you both for the welcome! I greatly appreciate the input and genuinely seek the expertise of those with experience in these endeavors. Many of the decisions I've made in advancing my efforts relate to prior experience in engineering unrelated technology. I want to preface any explanations of those decisions with a disclaimer that any presentation of information I've acquired and relied upon is only done so in an effort to promote further discussion and increased understanding and not as a defense or to promote debate centered on right or wrong. To date I've found the only true constant through out the overclocking community is that there seems to be little agreement in what methods are in fact correct.
The use and design of my case ventilation system centered around first and foremost maximum thermal efficiency and included to a lesser degree efficiency in response to temperature changes, providing airflow to achieve maximum efficiency of the CPU radiator, and maintaining a positive pressure to allow for a minimum accumulation of foreign particulate which all contribute to achieving the primary goal.
First the most efficient and responsive fan solution for the radiator is a push pull configuration which established the necessity of at least 4 fans providing flow out of the case. The case design then dictated that at least one more fan would be oriented to flow out as the top of the case provided for installation of 3 fans across the top. Having established that the system would have 5 fans flowing out any solution which provided positive pressure would need to exceed such in number even with the radiator impeding some of the outward flow. The case provided for an additional 6 which flow inward and satisfied the goal of creating and maintaining a positive pressure. I used jetflows exclusively as they eclipse all other 120mm fans by producing a maximum of 95 cfm while equaling the decibel level of those provided by Corsair with the CPU cooler. Admittedly this combination has the ability to be quite loud however careful control has provided for a very acceptable compromise. All of the fans are powered through the use of the motherboard CPU fan header and 3 system fan headers. MSI provides for the creation of fan curves in bios and I configured them to start at 30%@30C and reach 100%@70C. This has resulted in a cooling solution in which all the fans run at approximately 900rpm at idle and respond quickly, efficiently, and incrementally to load topping out at approximately 2200rpm all while constantly providing a positive pressure. So noise really isn't a factor unless the CPU and system are under significant load for an extended period.
Although I'm very pleased with the result of my ventilation solution it actually has created more questions for me as I wonder if the CPU temperatures I'm experiencing are a product of the cooling system response and efficiency and not due to proper application of voltage.
The overclocking voltages and frequencies I've achieved were through following this flow chart: http://www.tweaktown.com/image.php?...ate-intel-skylake-overclocking-guide_full.jpg
Which seemed to provide for reasonable voltages given the information provided here:https://siliconlottery.com/products/6700k49g
Thanks again and I look forward to all input from everyone here, Chris
