Compulab, maker of mini systems such as the fitlet and Airtop is bringing the compact, fanless concept to a powerful gaming system - with no less than an Intel Core i7-7700K and NVIDIA GeForce GTX 1080. The catch? Is is not yet available, pending an upcoming Kickstarter campaign beginning February 24.
The teaser image of the upcoming Airtop2 Inferno fanless gaming system
The Airtop2 is already available for purchase in a fanless workstation version, built-to-order with up to an Intel Xeon E3-1275 v6 and NVIDIA Quadro P4000 (starting at $2575 for that configuration before adding memory/storage), and this new "Inferno" version of the Airtop2 promises to be very interesting to silent computing enthusiasts.

A fanless gaming system with high-end components is only going to be as effective as its cooling system, and here Compulab has a lot of experience on the industrial/embedded side of things.

Compulab lists these specs for the Airtop2 Inferno (along with the teaser, "and a little more..."):
- Unlocked Intel Core-i7 7700K
- NVIDIA GeForce GTX 1080
- Up to 64 GB DDR4 2400 RAM
- 2x NVMe + 4x 2.5″ SSD / HDD
- 2x USB 3.1 + 7x USB 3.0 | dual LAN | front (and back) audio
Compulab has also provided some benchmark results to demonstrate how effective their fanless implementation of these components is, with results using 3DMark and Unigine Heaven available on the Inferno product page.
The company has set up a Q&A page for the Airtop2 Inferno, but pricing/availability info will probably have to wait until February 24th when the Kickstarter campaign is active.

Delidding a Kaby Lake processor such as the i7-7700k does not offer the same overclocking advantages as with previous generations when replacing the TIM gave you more headroom. Instead of being able to push your CPU past 5GHz, popping the lid off of a Kaby Lake reduces operating temperatures and likely extends the life of the processor ... or immediately ends it. If you don't have a 3D printer handy to make your own delidder, then take a peek at this review from TechPowerUp. They try out two delidding tools, one from Aqua Computer and one from Rockit which Morry has used; do be aware that any CPUs killed as a result of reading their review is the responsibility of the one who delidded.
"Intel mainstream CPUs have had a bottleneck in cooling due to poor heat transfer from the CPU die to the integrated heat spreader. Thanks to new de-lidding friendly tools released recently, it is now easier than ever before to handle this yourself and get a cooler running CPU. We examine two such solutions from Rockit Cool and Aqua Computer today, both of which promise fool-proof de-lidding and re-lidding"

Today Corsair announce a family of new pre-built systems, the Corsair One series. Two of the systems will be available for purchase at your favourite retailers and two will be exclusive to Corsair's web store.
All models have aluminium cases and an an integrated liquid-cooling system for both the i7-7700k as well as the GPU, be it a GTX 1070, 1080 or 1080Ti. All systems are built on a custom MSI Z270 Mini-ITX motherboard, a Corsair FORCE LE SSD with a HDD for extra storage, 16GB of Corsair Vengeance DDR4-2400 and an 80 PLUS GOLD rated SFX PSU.
They will hit stores later this March and will come with a two year warranty which includes dedicated technical support, 24 Hour Phone support and an included suite of self-diagnostic tools. You can read the full PR below the fold.

Recently [H]ard|OCP popped the lid off of an i7-7700k to see if the rumours that once again Intel did not use high quality thermal interface material underneath the heatspreader. The experiment was a success in one way, the temperatures dropped 25.28%, from 91C to 68C. However the performance did not change much, they still could not reach a stable 5GHz overclock. They did not let that initial failure discourage them and spent some more time with their enhanced Kaby Lake processor to find scenarios in which they could reach or pass the 5GHz mark. They met with success when they reduced the RAM frequency to 2666MHz, by disabling Hyperthreading they could reach 5GHz with 3600MHz RAM but only when they increased the VCore did they manage to break 5GHz.
Of course you must exercise caution when tweaking to this level, a higher VCore will certainly reduce the lifespan of your chip and delidding can have a disastrous outcome even if done carefully. If you are interested in trying this, The Tech Report has a link to a 3D printed tool to help you in your endeavours.
"Last week we shared our overclocking results with our retail purchased Core i7-7700K Kaby Lake processor. We then took the Integrated Heat Spreader off, replaced the Thermal Interface Material and tried again for 5GHz with 3600MHz memory and failed. This time, less RAM MHz and more core voltage!"

[H]ard|OCP had a chance to try out Corsair's upcoming Vengeance LPX 3600MHz DDR4 on a Kaby Lake based system. The XMP settings for this DDR4 were 3600MHz with timings @ 18-19-19-39-2T and the system booted with no problems at these defaults, an improvement from some scenarios with Skylake based systems. Running Prime95 for over a day posed no problem for the system, however Memtest86 did until the RAM voltage was bumped up to 1.41v from the default 1.36v at which point it could pass the tests with no problems. This shows some promise for overclocking addicts planning on upgrading to the refreshed Intel chip.
"We were lucky enough to get our hands on a new set of Corsair Vengeance LPX 3600MHz RAM this week and we immediately put it work with the new Intel Kaby Lake Core i7-7700K processor that is to be launched next month."

Someone, who wasn’t Intel, seeded Tom’s Hardware an Intel Core i7-7700k, which is expected for release in the new year. This is the top end of the mainstream SKUs, bringing four cores (eight threads) to 4.2 GHz base, 4.5 GHz boost. Using a motherboard built around the Z170 chipset, they were able to clock the CPU up to 4.8 GHz, which is a little over 4% higher than the Skylake-based Core i7-6700k maximum overclock on the same board.

Lucky number i7-77.
Before we continue, these results are based on a single sample. (Update: @7:01pm -- Also, the motherboard they used has some known overclock and stability issues. They mentioned it a bit in the post, like why their BCLK is 99.65MHz, but I forgot to highlight it here. Thankfully, Allyn caught it in the first ten minutes.) This sample has retail branding, but Intel would not confirm that it performs like they expect a retail SKU would. Normally, pre-release products are labeled as such, but there’s no way to tell if this one part is some exception. Beyond concerns that it might be slightly different from what consumers will eventually receive, there is also a huge variation in overclocking performance due to binning. With a sample size of one, we cannot tell whether this chip has an abnormally high, or an abnormally low, defect count, which affects both power and maximum frequency.
That aside, if this chip is representative of Kaby Lake performance, users should expect an increase in headroom for clock rates, but it will come at the cost of increased power consumption. In fact, Tom’s Hardware states that the chip “acts like an overclocked i7-6700K”. Based on this, it seems like, unless they want an extra 4 PCIe lanes on Z270, Kaby Lake’s performance might already be achievable for users with a lucky Skylake.
I should note that Tom’s Hardware didn’t benchmark the iGPU. I don’t really see it used for much more than video encoding anyway, but it would be nice to see if Intel improved in that area, seeing as how they incremented the model number. Then again, even users who are concerned about that will probably be better off just adding a second, discrete GPU anyway.
