Intel’s new Coffee Lake CPUs: Increased Thermal Load

With Coffee Lake, Intel has recently released its eighth processor generation. As part of the launch of the new generation of processors, a new chipset the Z370 has also been introduced.

While CPU coolers as offered by ARCTIC are still compatible thanks to the same mechanical socket, switching to the new Coffee Lake Processors requires a new mainboard due to its new chipset.

Motherboards with older chipsets (like Z270 / H310 / H370 / B360) are no longer compatible with Intel Coffee Lake processors despite the mechanically identical socket.

Up to 100 Watts extra load

The German magazine c’t examined four new motherboards with the chipset Z370 in a test in issue 23/2017. They discovered that in their default settings all motherboards overclock and operate the processors outside Intel’s specifications. The following mainboards were tested:

  • Asrock Z370 Extreme4
  • Asus PrimeZ370-A
  • MSI Z370-A Pro
  • Gigabyte Z370 Aorus Ultra Gaming

Intel’s restrictions regarding the turbo boost (concerning, for example, power supply and multipliers) are circumvented by all tested motherboards and result in a significant additional thermal stress.

In the case of Intel’s latest flagship model, the i7 8700K, it can lead to an increased power consumption of up to an additional 100 W. This causes a noticeably elevated temperature of the processor and requires a cooling solution that can cover this power peak.

Even if Intel officially states a TDP of 95 watts for the current top model 8700K, when using one of the mentioned motherboards under full load, a cooling solution for up to 180 W may be necessary. Alternatively, the default overclocking has to be deactivated in the BIOS.

 Powerful CPU Cooler necessary

We advise all users of Intel’s Coffee Lake and their K CPUs to pay attention to this extra thermal load via overclocking when choosing their cooler, or alternatively to disable the automated overclocking in the BIOS.

For the sake of the environment: ARCTIC changes to Online Manuals

We at ARCTIC have always felt committed to environmental protection and think “green”. As a carbon neutral company, we fully offset our greenhouse gas emissions through investments in renewable energy projects and recycling. In addition to the continuous optimization of the packagings of our products, we are always looking for new ways to live up to our responsibility to the environment. For this reason, we have been doing without printed manuals since this year.

Instead, we provide regularly updated user manuals in many languages on our website. The instruction manuals are always conveniently available anywhere and anytime and can be found on the respective product pages under “Support”.

Online Manuals can be found on our product pages

All products come with a QR sticker. Once affixed to a place of your convenience, the QR code leads the user directly to the product manual.

Included with each product: cards with a QR code for the manual

The positive feedback shows us that our customers perceive and support the conversion to online manuals. We are happy and motivated to continue our search and implementation of new measures to further contribute to enironmental protection.

ARCTIC at the Gandalf Roadshow 2017 in Sweden

HEJ SVERIGE! After an early start at 04:00 in the morning at the end of September, our colleagues Dina and Jehona arrived in Gothenburg in good spirits and in anticipation. It wasn’t for holiday though. Dina and Jehona had a full program during the roadshow with presentations in three cities ahead of them and they had packed a variety of our products.

Dina and Jehona at the Gandalf Road Show in Sweden

The start of the roadshow of our distributor Gandalf was in Gothenburg, the second station was Malmö and the last stop was in the Swedish capital Stockholm. The goal was to present ARCTIC personally, to get in direct contact with our Scandinavian customers, to meet new sales partners and to show the extensive ARCTIC product portfolio.

After a rainy arrival in Gothenburg, Dina and Jehona first opened their weather apps because they had hoped to see Sweden by the sun. Luckily this happened in the further course of their journey. They went on their way to the venue and took the train and taxis to collect some impressions from Sweden.

The welcome was very warm and first discussions with other event participants were already made during lunch. Various ideas about products and branches were exchanged.

Afterwards, they were present at our booth, presented ARCTIC and our various products and answered numerous questions. The constructive feedback directly from our customers was very valuable to us as we made new contacts.

The procedures were the same all three days of the event. In addition to a few lectures and a joint dinner, the exhibitors presented their products at their mobile stands.

ARCTIC Products at the Roadshow in Malmo / Sweden

The three days of the roadshow weren’t monotonous though. After all, every day Jehona and Dina went to another, interesting city in Sweden. The harbor town of Gothenburg, the romantic Malmö and the unique Stockholm; Dina and Jehona would have liked to explore all the cities extensively, but unfortunately there wasn’t enough time. But they decided that they will go back to Stockholm at least one more time.

On all days there was a very harmonious and entertaining atmosphere – the drink vouchers which offered wine and swedish beer among other beverages certainly contributed to the atmosphere 🙂

As a conclusion, it was an all-round positive experience for Jehona and Dina to be at this professional and interesting roadshow.

How to cool AMD Ryzen Threadripper Processors?

The Ryzen Threadripper is the new CPU from AMD for high-end systems – which possibilities do you have to efficiently cool a CPU with up to 16 cores?

Up to 16 cores and 32 threads, 4,096 pins, 64 PCI-E 3.0 lanes, quad-channel DDR4 RAM and 180 W TDP: The new AMD Ryzen Threadripper are very powerful CPU and with sufficient reserves even for demanding tasks.

The physical dimension of the Threadripper alone show the need for a powerful cooling solution. With the mentioned 4,096 pins the CPUs are significantly larger than other processors for private use.

Due to the size the new SocketTR4 was developed with its own chipset, X399. Cooling solutions, which still fit on equally new AMD AM4 socket, can’t be mounted on sTR4 Mainboards.

With prices starting at 800 EUR, the CPUs are not a bargain, but they are among the most powerful processors a home user can currently buy. Threadripper Processors promise excellent performance in particularly when multiple CPU Cores are needed, e.g. for gaming, video rendering, and other demanding applications.

But how to cool such large and powerful processors effectively?

Adjusted CPU Cooler needed

Because of the larger design, conventional CPU air coolers, which are compatible with AMD’s AM4 Socket and are designed for regular Ryzen processors, won’t fit the sTR4 for Threadripper CPUs.

Threadripper CPU coolers can, however, usually also be mounted and used on Ryzen processors in the AM4 socket.

Due to the high performance and the resulting high heat level of about 180 W TDP, AMD conducted extensive tests to check the compatibility of the cooling solutions available on the market.

The list of AMD certified Tthreadripper CPU coolers can be found here.

Threadripper CPU Cooler from ARCTIC

Since we are a close partner of AMD, a mounting kit for our CPU coolers of the Liquid Freezer series are provided with each Threadripper CPU. This allows the Liquid Frezer 120, Liquid Freezer 240 and Liquid Freezer 360 to be used to cool Threadripper CPUs.

ARCTIC Freezer 33 TR

Threadripper certified: The new ARCTIC Freezer 33 TR

If, on the other hand, you prefer regular air cooling for Threadripper, we recommend our newly developed Freezer 33 TR. It is designed for CPU with a TDP of up to 200 W.

The Liquid Freezer 240, 360 and the Freezer 33 TR are also certified by AMD as a cooling solution for Threadripper Processors.

So if you are interested in the AMD Ryzen Threadripper and wonder how it can cool it effectively and quietly, we from ARCTIC provide powerful yet silent Threadripper CPU Cooler.
