Skylake can run at 1.4v 24/7 as long as you have a good cooler, the voltage regulator has been moved to the chipset meaning they run cooler.
I have an h100i and my 6700k 4.7Ghz @ 1.38v never goes above 50c.
The max is 105tj but the net says never have prolonged heat above 85c (like its predecessors).
UNLIKE Skylakes predecessors you can run Skylake from 1.3v - 1.4v 24/7
I dont think i can link another forum (for fear of the ruthless mods and their ban hammers) but here is a snippet from their guide -

You overclock your system at your own risk. Overclocking your CPU could cause the CPU to fail, or reduce its useful life. Neither MyCE.com nor myself will take any responsibility for any damage that may be caused to your CPU or system by following this guide.
"Overclocking guide for Intel 6th generation Core processors (SkyLake).
If you are an extreme overclocker then this guide is probably not for you. What I intend to cover in this guide is a sensible CPU overclock that can be used 24/7, and all without power consumption going through the roof.
There are many ways to overclock these CPUs and I'm not going to claim that this way is the best way, but simply that it should work for 95% of the people who would like to get some extra grunt from their CPU without the need for extreme cooling solutions, or having to worry about power consumption getting out of hand.
First of all, let’s cover what you will need to successfully overclock a SkyLake CPU.
The first thing of course is a CPU with an unlocked multiplier. For SkyLake that would be a CPU model with a "K" at the end, 6700K for example. Overclocking these CPUs is simply a matter of stepping up the multiplier. Of course it isn't quite that simple, as you will need to watch how much voltage you push through these CPUs, and also that stepping up the voltage and clock speed will inevitably produce more heat.
SkyLake can also be overclocked using a base clock method, where you leave the CPU ratio alone and clock the system using BCLK. Or you can use a combination of CPU ratio and BCLK to achieve your desired overclock. For this guide, I will only use the simpler core ratio method of overclocking the CPU.
Chipsets
The next thing you will need is a chipset that allows the CPU to be overclocked. For this we will need a motherboard with the Z170 chipset. At the time of writing this guide, the Z170 chipset was the only one available.
A high end cooling solution.
If we are going to look at overclocking seriously then the first thing you will require is a high end cooling solution. The SkyLake 6600K and 6700K CPU’s do not come supplied with a stock cooler. This should tell you that the cheap Intel stock coolers supplied with previous CPU generations are not up to the task, even at default CPU speeds on this platform.
Some important things you will need to keep in mind.
SkyLake and the Z170 chipset are very different from the previous generation of Intel Core processors and chipsets, and it has taken me a few weeks to learn and understand how to overclock this platform properly. In order to get a safe and reliable overclock on this platform is going to require voltages to be changed that if set incorrectly will damage the CPU, RAM, or motherboard. So please read the voltage settings and warnings very carefully.
With a new platform come some unexpected issues with what you may consider a stable overclock. An example would be that I had overclocks that were stable during a 30 minute run of the AIDA stability test, but the system would refuse to recognise a USB stick when inserted into a USB port. After this, the system wouldn’t close down. After much trial and error, I finally tracked this issue down to DRAM stability, and as we’ll discover a little later, DRAM stability on this platform is not quite as simple as it sounds, even at default DRAM speeds of 2133MHz.
Let’s get started.
For this guide I will be using the following hardware and software.
• CPU: Intel Core i7 6700K CPU (SkyLake)
• Motherboard: Asus Z170 Deluxe, with UEFI version 0801
• Corsair Vengeance LPX 2666MHz DDR4
• CPU cooling: Be-Quiet Dark Rock Pro 2 (high end air cooling)
• Power Supply: Antec 550 Watt modular (Important. The PSU must be compatible with Haswell or later CPU’s, and support those CPU’s low power states)
• OS: Windows 10 Pro 64bit
• CPU voltage monitoring: CPUZ.
• CPU temperature monitoring: RealTemp
• Stability testing (quick): CineBench R15
• Stability testing (full test): HandBrake X264 video encoding.
The maximum core temperature is as follows.
• TJMax is 105c
If TJmax is reached then the CPU will throttle back to prevent permanent damage to the CPU die, but you don't want to get to close to those temperatures. For SkyLake, 85C really shouldn't be exceeded for any prolonged period.
Measuring vcore voltage.
This is the amount of voltage that is being supplied to the CPU cores.
You will no doubt have seen on some overclocking sites, that people are pushing crazy amounts of voltage through the CPU cores, in order to get that last 100MHz of speed. For this guide we will be a bit more conservative and sensible.
The maximum safe voltages for 24/7 use are as follows.
• High end air cooling 1.35 volts
• High end water cooling 1.40 volts
Measuring the core voltages is again very easy, and free. CPUZ is probably the best option for this."
