阿尔法冷 Eisbaer 200 CPU 黑色水暖器说明书
What is it?Alphacool Eisbaer 200 CPU - BlackHighlightsThe Alphacool Eisbaer is an expandable, refillable CPU all-in-one watercooler with a pure copper radia-tor. The Eisbaer can be expanded with additional Eisbaer Ready products such as the Eiswolf GPX-Pro graphics card cooler, among others.•Quick connectors make it easy to expand and upgrade with Eisbaer Ready• Pure copper radiator for maximum cooling performance• DC-LT 2 Ultra Low Noise ceramic pump for whisper-quiet operation •Refillable via the fill port on the reservoirArticle textWith the “Eisbaer”, Alphacool is fundamentally revolutionizing the AIO cooler market. Where traditional AIO CPU-coolers are disposable products which are neither upgradeable nor refillable, the Alphacool “Eisbaer” is modularly built and can be upgraded, rebuilt or refilled at any time. This means that the “Eisbaer” is not only an AIO, but also fully built on classic water cooling components. That means it is quieter and more powerful than the average AIO solution.RadiatorAlphacool depends on a radiator made of pure copper. The base of the radiator is the popular Alphacool NexXxoS series, which is well-loved around the world. The pure copper construction raises the cooling performance enormously compared to the usual aluminium radiators used in classic AIOs. The slight thickness of the fins ensures enormous cooling power in fans with low rotational speed. This ensures that the performance of the “Eisbaer” when adjusting the fans down decreases much more slowly than in radi-ators with higher fin thickness.HosesThe flexible PVC hoses make installing the “Eisbaer” easy. These hoses are easier to arrange and move into the right position. So the hoses don’t bend and stop the flow of the water, both hoses have been fit-ted with anti-kink springs. The 11/8 mm size is also a standard in the water cooling field, alongside the13/10 and 16/10.Quick-lock closureThe “Eisbaer” was designed with expandability directly in mind. This is why you’ll find a quick-lock closure on one of the hoses. This quick-lock mechanism is compatible with Alphacool HF quick-lock closures (1010383, 1010394, 1010395, 1010442), with which the circuit can easily be expanded to include anything from a radiator to a graphics card cooler. Furthermore, the “Eisbaer” is compatible with the upcoming Alphacool GPX-Pro graphics card AIO, which will use identical quick-lock closures.ConnectorsAll connectors are based on the classic G1/4 inch thread, the standard thread in the water cooling field. This way, all attachments can be switched out for others any time as desired. This also means that, for example, you could later decide to switch to thicker hoses or even HardTubes and set your system uniquely apart.All these features make the “Eisbaer” cooler into something extraordinary. Its enhanced appearance from the illuminated logo and the illuminated reservoir, which also contains the pump, lets the interior of your PC shine in a whole new way. The soft-touch surface of the pump case is a further visual highlight.With the “Eisbaer”, you get an all-around perfect product that is not only extremely high-powered but also works very quietly.PumpsThe basis of the pumps is the Alphacool DC-LT 2 Ceramic, also available separately. The pump runs ex-tremely quietly and can be regulated to between 7 and 12V. It can also be regulated through the mother-board. If the “Eisbaer” is being run alone, the 7V setting will still have next to no performance loss, as shown in diverse test results. The insulated pump case further perfects the noise generation and ensures that vibrations are almost completely absorbed.The smooth and shiny polished copper base of the cooler ensures optimal heat absorption and can relay the heat over the fine slit structure of the cooler to the water quickly and efficiently.To operate the Alphacool Eisbaer 200 CPU - Black at least one 200 mm fan is required. There are NO fans included in delivery!。

Note thatthe carousel is marked for each filterposition 1-5 (or 1-8). You can arrangethe filters any way you like. The defaultin CCDOPS, starting with position 1 is:Red, Green, Blue, Clear and Lunar. Youcan change these to any designation youlike. Keep in mind that CCDOPS willdefault to position 4 at startup assumingyou wish to start with the clear filter.When all the filters are installed, replacethe filter retainer and secure it with the 5(or 8) Phillips head screws. Do nottighten these screws more than isnecessary to keep the filters fromrattling in their cells. Over-tightening may damage the filters. Replace the filter wheel's front cover being careful to tuck in any loose wires so that they are not pinched and check that the cable retainer is tucked inside the bottom cover to prevent the cable from being pulled out the slot. Figure 11.3.Setting Up the Filter WheelAfter the drivers have beeninstalled on your computer, plugthe short pig-tail into the ST-8300's I2C port. Figure 12.Start CCDOPS, plug in power toyour camera, and attach the USBcable from the camera to yourcomputer.Once you establish a connection with the camera, go to the Filter Menu in CCDOPS and select Filter Set Up and then select the CFW9 filter wheel as shown in the screen shot at left. (The FW5-8300 uses the same electronics and commands as the CFW9 filter wheel). If you are using CCDSoftV5 select the camera as "ST-402" and filter wheel as "CFW9" as shown in the screen shot below.SBIG Astronomical Instruments, A Division of Diffraction Limited.59 Grenfell Crescent, Unit B, Ottawa, ON Canada, k2G 0G3Tel:613.225.2732|Fax:225.225.9688|E-mail:*****************| © 2015 Diffraction Limited.

VNXe3200
最新VNXe 3200介绍（上）转载请在文首保留原文出处：EMC中文支持论坛https:///go/chinese介绍美国当地时间2014年4月30日，EMC发布了最新一代的VNXe存储，VNXe3200。
这次发布的VNXe3200简直就是一个强大的多功能小型存储阵列。
那就让我们来详细了解一下最新的VNXe3200吧。
更多信息亮点：VNXe3200支持FC新VNXe针对入门级阵列使用了一个全新的架构。
它的架构类似于VNX，但管理系统却非常小。
两个存储处理器（SP）都包含在由12或25个磁盘组成的数据处理器机箱（DPE）里面。
为了减少物理尺寸，SP没有被单独拆分出来，而是将SP建立在第一磁盘架。
整体规格包括：∙最大驱动器数–初期为50个（2014年内可达150个）∙总系统内存 - 48GB（每个SP 24GB）∙驱动支持的类型 - 2.5”或 3.5”SAS，NL-SAS以及闪存（Flash）∙协议支持 - SMB，NFS，iSCSI和光纤通道（FC）物理端口 - 4个10GBase-T端口和4个8Gb光纤端口它运行MCx操作环境，就像当前的VNX。
这一点很重要，因为它拥有与VNX相同的多核性能增强，以及许多相同的功能，例如FAST VP。
软件功能的增强像当前的VNX一样，新VNXe的软件更新也非常显著。
MCx可以更好的利用新式的多核CPU，并拥有一些非常强大的软件功能。
相信之前是从未见过这种规模和价格的阵列。
FAST VPFAST VP（Fully Automated Storage Tiering Virtual Provisioning，全自动存储分层虚拟资源调配）可以允许你创建一个包含不同类型磁盘的池。
根据需要，在池中，阵列将“向上”或“向下”移动数据来加快（SSD）或减慢（NL-SAS）磁盘。
我们可以清楚的看到一个池由SSD，SAS和NL-SAS构成，并让阵列进行处理将数据放在正确的层。
“土豪”们的大面子！四款超大屏幕液晶电视体验对比
“土豪”们的大面子！四款超大屏幕液晶电视体验对比梁景裕【期刊名称】《消费电子》【年(卷),期】2015(000)005【总页数】10页(P54-63)【作者】梁景裕【作者单位】【正文语种】中文对于很多家庭消费者而言，家里的液晶电视就如同自己的“面子”一样屏幕越大越好。
尤其是很多收入水平达到“土豪”级别的消费者，50英寸的液晶电视已经满足不了他们对“面子”的需求。
于是，各大品牌都纷纷推出80英寸以上的超大液晶电视，本期《消费电子》评测室就选出了四款目前市面上主流的超大液晶电视进行体验对比，看看这些“土豪级”液晶电视的表现如何。
夏普LCD-90LX740A是目前行业里最大的90英寸液晶电视。
它的面积是60英寸的2.3倍、70英寸的1.7倍，同时也搭载各种先进技术，是一款拥有超高性价比的机型。
90英寸超大屏幕搭配超薄机身外观方面，夏普LCD-90LX740A虽然有着90英寸的超大屏幕，不过却拥有超薄的机身，搭载的侧入式LED背光源技术让整体机身厚度非常薄。
底座方面，这款夏普电视采用了传统的底座设计，确保了电视放置的稳固性。
在细节方面，夏普LCD-90LX740A电视的设计非常用心，电视机身前部的LOGO 不仅是机身品牌身份的象征，而且给人画龙点睛之感，在灯光的照耀下更显眼。
而作为一款数字电视一体机，夏普LCD-90LX740A不仅支持WiFi、DLNA等网络连接，还支持OPC自动亮度调节，拥有3个USB接口、4个HDMI接口、D-sub接口等丰富扩展空间。
除了HDMI和USB，它还支持MHL连接。
拥有这些，用户便可以在90英寸的大屏幕上浏览手夏普LCD-90LX740A 12万元机、硬盘、电脑、蓝光机等各种设备的内容，实现丰富的扩展体验。
另外，在节能环保方面夏普也没有怠慢，由于融合了X超晶面板和直下式的背光源，本机型的目标是取得能效等级1级。
百视通合作智能系统界面先进的智能界面和强大点播功能等智能体验也同样是LCD-90LX740A的一大亮点。
