Oil cooling: Deep fried, or deep energy savings? - ExtremeTech
Published: Thursday, April 12, 2012 | By: DennisSince the early days of "alternative" cooling people have explored better ways to cool their computers. Watercooling is by far the most popular of these and I have seen several modders building fully submerged PCs but these projects never got the attention of enterprise computing for various reasons.
By fully submerging the hardware, oil is better able to affect the transfer of heat from the components and out of the facility. Much like the home-built "aquarium PCs," oil-cooled servers also have a pump to circulate the oil and a radiator to cool it down before it's returned to the system. In that respect it is similar to watercooling - just without using water-blocks. Like water, oil has a higher specific heat capacity than air, meaning it can absorb more heat for a given volume of coolant.
Oil cooling does have its challenges, the biggest is how do you handle contaminates in the oil? Say one of the servers has a hardware failure causing a chip to burn. Assuming the oil burn how do you handle conductive particles into the oil? Given this doomsday scenario you could lose an entire rack of servers in rather quick order.
Maybe the cost savings are worth the risk.

Microsoft Visual Studio 11 Preview @ Techgage
Published: Thursday, April 12, 2012 | By: DennisYou would think that for a .Net developer like myself I would be totally onboard when it comes to Visual Studio. However, I don't use VS for my development instead choosing to code my projects longhand in an editor called Homesite. There are some limitations but I find my code to be cleaner and it allows me to code the way I like.
I'm sure I'll eventually switch to the darkside but to be honest VS has always been code heavy and often saves extra files that aren't needed for the project and just add to the clutter.
With the next version of Visual Studio soon to be upon us, we're taking a look at what's worth waiting for. While some animosity exists around certain decisions made by Microsoft, VS11 brings a lot to the table, most notably the addition of a robust environment for creating Metro-based apps.
Gotta love that MS is keeping up and releasing everything a budding developer needs to create applications for their operating system. That, if anything, is why they command the market.

Death Watch: Microsoft to kill Windows XP in two years
Published: Tuesday, April 10, 2012 | By: DennisDon't you hate it when you create something so good and so successful that it will never die? HPUX, ya its still around, Oracle? yep still alive, Windows XP? whoa..
The end is coming. Repent!
That's the message from Microsoft as it reminded consumers that its support for Windows XP SP3 and Office 2003 will end on April 8, 2014.
According to Microsoft marketing director Stella Chernyak that means the software giant will nix security updates, non-security hot-fixes and technical support after that date. So let the countdown begin. You now have less than two years to get your affairs in order and hightail it to more current software.Keep in mind this is "support" for the latest service packs. As far as I know M$ doesn't have a remote kill switch that would fully disable the OS. Now if we could get overclockers to realize that Win7 is just as fast as XP we'd be making progress.
(Well except for 3DMark 01, I have proven to myself that XP is faster when using that bench)

DARPA Seeking to Build (Friendly) Terminators
Published: Tuesday, April 10, 2012 | By: DennisIt was bound to happen sooner or later, Terminator robots will soon be among us. Maybe these will be iRobot style with the three laws or flat out "stand them up and knock them down" cyborgs from the future attempting to kill the mother of the leader who defeated them. The jury is still out but the fact remains, it will happen.
The government is looking for a few good robots. But never fear, this year's DARPA Robotics Challenge isn't a casting call for positronic killing machines—instead, teams are being asked to design robots capable of driving a vehicle, using power tools to bash through walls, and even replace a cooling pump, for a $2 million grand prize.
Up to $34 million in total will be eligible in contracts and funding, the Defense Advanced Research Projects Agency said Tuesday.
The goal, DARPA said, is to produce a robot capable of assisting humans in dangerous or degraded environments, using unmodified tools designed for humans.I wonder if they will have rubber skin or go straight for human flesh?

Intel Z77 Chipset Launch Day
Published: Monday, April 9, 2012 | By: DennisIt is the much anticipated launch of the Intel Z77 chipset for the LGA 1155 socket processors. As many of you already know this is the Sandy Bridge platform that was made popular by the P67 and Z68 chipsets from last year.
Many of these reviews are just "pre"-views since the real reason for the Z77 release has yet to be launched.
Currently we have a Gigabyte Z77X USD3H in the lab and will be posting our article a little later today so be sure to come back and check it out.

Asus X79 Sabertooth Motherboard @ Bjorn3D
Published: Friday, April 6, 2012 | By: DennisWe have a new review up of the "classic" Sabertooth P67 motherboard that started the trend of Thermal Armor, be sure to check it out.
If you are looking for a Sabertooth board "without" a full set of armor and quad channel memory controllers make sure to give this board a look.
The Asus Sabertooth X79 is the Asus offering that represents high quality and high life expectancy parts via the TuF components. Lets see how well it performs with its excellent MTBF components.
Notice the fan on the South Bridge and no heatpipe connecting it to the PWM? ya....

Foxconn Nano PC nT-i1500 Barebone Review @ Madshrimps
Published: Tuesday, April 3, 2012 | By: DennisThose of you who have been following Foxconn (besies anything related to the Apple i(andything)) will have noticed that they have started to migrate away from channel motherboards to AIO barebones systems and multimedia PCs. the Nano PC nT-i1500 is one such product that will likely change how the mainstream uses a desktop PC.
Foxconn has brought us to the table the latest generation of Intel Atom CPUs, by using the small Nano PC chassis which features about the same layout inside as the barebones we have tested from them in the past. The system power consumption is very low, temperatures are good in load and the noise generated is decent. Only thing that needs to be fixed to make this product fully functional is the VGA driver which in its current state offers low performance in both 2D and 3D environments, and Intel does not offer any support for x64 OSes.
Foxconn has always had their hands in barebone system design and found them to be quite profitable since customers buy them as a white box and can rebrand them anyway they wish.

Blackle vs. Google Monitor Power Consumption Tested @ PCSTATS
Published: Monday, April 2, 2012 | By: DennisOk so as a designer I have nothing against black web designs, they do look badass but also scream "I am a dated bastard you had better like something here!". Along the same lines it stands to reason that LCDs have to spend less power displaying black designs since most of the lights will be turned off.
Is the search page, Blackle.com, really an energy efficient alternative to Google? The theory is websites with black background save energy. PCSTATS finds out if this is a blatant green washing, or an earnest energy saving tweak for something we use every day.
By the looks of it an all black design is more power efficient and LCDs use less power than CRTs but does changing your site from white to black save you more power than simply trashing the CRT??
uhhh, no.

MSI Radeon HD 7970 Lightning review @ Guru3D
Published: Friday, March 30, 2012 | By: DennisOne of the first HD 7970's to feature a completely custom PCB the MSI Radeon HD 7970 Lightning. I almost bought one of these the other day but when I came to my senses they had sold out at Newegg.
We review the MSI Radeon HD 7970 Lightning. What a product to look at, the R7970 lightning has a very rare design, comes with only the best components, has voltage monitoring headers, comes pre-overclocked (extensively at 1070 MHz) and allows to be voltage tweaked at many levels.
To pursue Eyefinity they have made the card Eyefinity6 compatible, by use of four DisplayPort connectors and two single link DVI connectors you can get six monitors running. Though realistically nobody does that as you have that ugly bezel from left to right smack down in the middle of you field of view.
There's another feature though, to give the product a little more 'niche' MSI implemented a small add-on board that is called a GPU-reactor which functions as a power supply module which, when installed on the back of the GPU.What really surprises me is that we are not seeing more companies take such a radical approach to custom video card PCBs, Yes they are a little more expensive and people "other" than overclockers will buy them. it's just a matter of cost.
