New Freezer 12/12 CO Coolers Push the Arctic Company Forward

On a recent day, the Arctic Co. has broadened its CPU coolers range with the Freezer 12 and Freezer 12 CO (CO means “continuous operation”) samples under the ACFRE00027A and ACFRE00030A code names.



The heatsink is the same for both coolers; fans are different, though. The Freezer 12 fan is built on a hydrodynamic bearing, and Freezer 12 CO is based on a fan with a dual ball bearing, which operates extremely long comparing to the better part of models.


The heat dissipator is designed so, that U-shaped 6 mm copper heat pipes stay in touch with each other, thus enhancing the cooling system productivity. The aluminium pressure plate and 45 bent radiator fins also contribute to that.


Fans start to operate at the PWM signal with 40 % pulse width and ensure passive CPU cooling while completing trivial tasks. This lets coolers work silently during such periods. The ultimate noise rate is 22.5 dBA, and the max speed comes up to 2,000 rpm.


Both Arctic novelties support …

The single-board Hardkernel Odroid-XU4Q PC Got a Massive Heatsink Instead of a Fan

The single-board Odroid-XU4 PC by Hardkernel, released in 2015, has got its new modified successor, called Odroid-XU4Q, which allows to construct devices for smart houses and Internet of things. There are no profound changes, though. A new version obtained a rather large sized (40 х 40 х 25 mm) heatsink instead of a low-profile fan. Such a solution makes the PC operation completely silent.



The board is based on the Samsung designed Exynos 5422 processor; the chipset is built on the ARM big.LITTLE architecture – it has four Cortex-A15 cores with up to 2.0 GHz clock speed and four Cortex-A7 cores with up to 1.4 GHz frequensy. The integrated Mali-T628 MP6 controller provides graphics processing.


The novelty from Hardkernel features 2 GB of RAM, a microSD card slot, one HDMI 1.4, one USB 2.0, two USB 3.0 and Gigabit Ethernet interfaces. The flash module capacity can be equal to 16, 32 or 64 GB.


Customers can purchase a monoboard ODROID-XU4Q PC at the approximate $60 …

Motherboard ECS Z77H2-A4 Review

Chipset Intel Z77 can’t be called a novel product in the market, since it has already transformed into a customary platform for personal computers. The versatility of motherboards employing this chipset is countless, in fact, and each and every consumer is able to find the one to his specific needs. ECS boasts its own inventory of boards based on Intel Z77; Z77H2-A4 is an intermediate item between hi-end and entry-level models, due to its alluring price and improved functional facilities. This board attracts primarily thrifty customers who would like to get all modern commodities for a sensible price.



Design and Layout


Budgetary orientation of ECS Z77H2-A4 motherboard is manifested, first of all, through a diminished PCB dimensions. Nonetheless, the model accommodates a couple of PCI Express Graphics slots with the allotted twenty rails of PCI-e bus. There is no symmetric rail distribution between the slots, so the second PEG slot receives only four rails. The board’s …
