We've even seen both Intel and AMD announce the inclusion of liquid-coolers for their upcoming processor lines. Today we're going to take a look at the Corsair Hydro Series, consisting of the H60 High Performance, H80 High Performance, and H100 Extreme Performance liquid CPU coolers.</p>
<p>Corsair has teamed up with CoolIT Systems this time around, while they have also partnered with Asetek for other Hydro Series products (H40/H50/H70/H70 Core). For now, our focus is on the H60, H80, and H100. How well do these cooler work compared to top air-cooling solutions, and are they worth the added cost? Let’s find out.</p>

Today we are going to talk about three Socket AM3+ mainboards based on a combination of AMD 990FX North Bridge and AMD SB950 South Bridge from the leading mainboard makers. They are Asus Crosshair V Formula, Gigabyte GA-990FXA-UD7 and MSI 990FXA-GD80. We will check out their packaging and accessories, design and functionality, BIOS options, overclocking potential, performance and power consumption.
Back at CES 2011 EVGA showed off an interesting concept card featuring 2 GF104 GPUs on a single board. The resulting product was the EVGA GeForce GTX 460 2Win, a true dual-GPU card packing 2 GTX 460s on to a single board. EVGA has since refined this product by replacing the GTX 460s with GTX 560 Tis, and today is launching the next 2Win card: the EVGA GeForce GTX 560 Ti 2Win. Priced at $519, EVGA has the GTX 580 set in their sights, claiming to offer 30% better performance for the price. But can EVGA’s dual-GPU behemoth really surpass NVIDIA’s flagship video card? Let’s find out.
The world economy may still be in recession but the fall of 2011 has every chance to become one of the hottest seasons in the history of the gaming industry. Despite the fact that a lot of highly anticipated projects have been postponed, battlefield 3 is out. How resource-demanding is the game that is destined to become a fave of millions in just a few weeks ?
Platter density has been the crutch of hard drive makers in recent history. Increasing spindle speeds can reduce random access latency, but at the expense of cost and thermals. Improvements in random access performance via increasing spindle speed pale in comparison to what is possible with solid state storage, not to mention that driving motors at speeds beyond 10,000 RPM becomes quite difficult. The focus on increasing platter density is also difficult, but higher density platters can actually lead to reductions in power consumption rather than the opposite (through a reduction in the number of platters per drive). There's also the fact that if you can cram more data on a single platter there's a direct impact on sequential accesses.
Yesterday Seagate announced its transition to 1TB platters with its new 7200RPM-only Barracuda line. The move marked a significant change for Seagate as it is phasing out the Barracuda Green brand, and shifting the focus of the high-performance Barracuda XT. The Barracuda Green was a rebrand of Seagate's Barracuda LP, designed to convey the lower power consumption enabled by its 5900RPM spindle speed.
Seagate decided that the performance loss of moving to 5900RPM wasn't justified by the power savings. It believed that by introducing a more power efficient 7200RPM drive it could deliver the best of both worlds, negating the purpose of the Green line. For most desktops, Seagate has a point. The couple of watts you save by slowing down the motor aren't really realized in a system that idles at 60W and can consume over 100W under load. On the other hand, the performance drop is definitely noticeable. Hard drives have pretty bad random access performance to begin with, and slowing spindle speed isn't going to help.
Random write performance goes up by almost 20% when you compare the Barracuda XT to the Barracuda Green. Performance in this test is mostly governed by spindle speed (and firmware), so it makes Seagate's case perfectly.
There is a segment that Seagate isn't considering as it decides to axe the Green line: the home server market. If you're doing mass archival to some external storage, random performance is likely not a big concern. Instead, all you want is cheap, low-power storage.
Come February 2012, if you want a Green drive, you'll have to shop with Western Digital.
At the other end of the spectrum, the Barracuda XT has been Seagate's performance flagship. This brand isn't going away. Instead Seagate will introduce a solid state hybrid drive under the Barracuda XT banner at some point in the future.
Everything else now falls under the bare Barracuda label. High capacity drives should become more power efficient thanks to a reduction in the number of platters, and performance should go up thanks to increased platter density.
Seagate sent along a new 3TB Barracuda for us to put through the paces.
This legendary sequel has undergone a number of modifications and reincarnations, but one thing remains the same: everyone is impatiently looking forward to the new round of this strategy game. This year we will be enjoying Might & Magic Heroes VI and, trust me, you will need a good graphics card for that.
Allow us to introduce to you another new cooler from Cooler Master. It is the eighth model in the Hyper series from this maker.
<p><span style="font-size: small;">More and more lately, mini-ITX boards are becoming very feature rich and users are needing fewer expansion cards in their desktop systems. Where once upon a time we'd need a wireless card, a video card, maybe an eSATA card and/or a sound card, now modern mini-ITX boards can cover just about all of these bases short of the GPU. TV tuner cards aren't even what they used to be with vendor lock-in by cable companies. All of that means that in many cases (no pun intended), all the end user is really going to need is the single PCI Express x16 the board provides.</span></p>
<p><span style="font-size: small;"> Addressing this segment of users, Lian Li sent us their PC-TU200 enclosure, a mini-ITX case that offers two expansion slots just for those double-wide video cards that have become de rigeur. The TU200 includes a carrying handle at the top that makes its purpose abundantly clear: producing a case perfect for LAN warriors.</span></p>
<p><span style="font-size: small;"> When we were first contacted by Lian Li's PR team, we were posed a question: what do we want to see? Our coverage of full- and mid-towers so far has been pretty good, but smaller enclosures have oftentimes gone by the wayside. So while we do have a couple of larger cases from Lian Li on the bench waiting for review, the TU200 is both one of their newer releases and also one of their most compelling. Cursory examination of the enclosure suggests that for both thermals and performance, it should be a big winner similar to (one of my personal favorites) SilverStone's Temjin TJ-08E, using a similar single-fan wind tunnel design.</span></p>
<p><span style="font-size: small;">There's really no getting around it: the TU200 is tiny. At just a touch under seven pounds, this enclosure is substantially lighter than my cat (who isn't stunningly overweight for an indoor cat if you can believe it), and frankly smaller to boot. Between the diminutive dimensions and the surprisingly rich internal design, one has to wonder if there isn't some kind of strange witchcraft at work to get all of these parts to fit into this tiny enclosure. As it turns out, a little bit may be involved.</span></p>

We will talk about the features, performance and acoustics of the two new top-coolers from Cooler Master and Deep Cool. What new things can the developers offer us in this form-factor today ?
“Venom Voodoo, this cooler is definitely rock and roll” – this brief and extensive characteristic Akasa used to describe their new processor cooler. Let’s see how much rock and roll there is in the new Akasa cooling product.
