ASRock's High-End Vision 3D HTPC Reviewed
by Ganesh T S on October 3, 2010 10:20 AM EST
One of the main challenges faced by ASRock in designing the Vision 3D was to handle the extra heat generated by the GeForce 425M. While the Core i3-370M has a TDP of 35W only, the GPU has a TDP of 27W. While the Core 100 had a fan on top of the CPU and another fan to keep up the air circulation / ventilation within the unit. While a similar solution could have been used in the Vision 3D, it would have made it necessary to have fans with higher noise potential. In this section, we will try to analyze the thermal design of the Vision 3D.
The GeForce 425M MXM module has a TDP of 27W, and it is passively cooled. The MXM card is fully covered by a thermal copper pad and this is connected to a heat sink of sorts with a thick copper heat pipe, as can be seen in the picture below.
The Vision 3D uses a pure blower solution and gets rid of the case fan altogether. The blower and a thermal pad are placed above the processor and the H55 chipset as shown in the picture below.
The above two thermal solutions are combined together as shown in the picture below.
The single blower solution replaces the blower and fan solution of the Core 100. However, the single blower solution requires ventilation slots around the bottom panel to taken in the cooler air from the surroundings. It is advisable to place the unit on a hard surface so that the bushes at the bottom keep the unit raised. This allows for better airflow.
Though blowers are often thought of as being noisier than fans, the elimination of one of the fans (when compared with the Core 100) results in a quieter solution, as we will see further on in the review.

Thanks, fixed :)nitrousoxide - Sunday, October 3, 2010 - link
A Seagate Barracuda Momentus XT 500GB would do much better job than WD Scorpio Black.LtGoonRush - Sunday, October 3, 2010 - link
A Seagate Momentus XT 500GB would cost nearly twice as much as the WD Scorpio Black 500GB ($130 vs $75 at retail), and the performance difference is rather unimpressive. In the tests where the Seagate can make use of its SLC cache it can take the lead, but in most tests the Scorpio Black is faster, especially when seek times or write performance come into play, since those are Seagate's major weaknesses.BansheeX - Sunday, October 3, 2010 - link
Cool box but LOL at the THX logo being slapped on it. They used to put that on heavily compressed DVD mixes, not all of them good either. Consumers don't care anymore.ganeshts - Sunday, October 3, 2010 - link
Personally, I don't care too much about the THX either :) If you are using HDMI for audio, it doesn't even appear in the picture.The internal audio codec is advertised with THX, so the HTPC using it gets the additional marketing point too :)

you guys did such an excellent job with this review! thanks for all the hard work and effort you guys put in!Shiitaki - Sunday, October 3, 2010 - link
I'm not seeing the value here. A thousand dollars to stream content, and play blurays? One of the previous replies you stated that there was no native bluray support for the mac mini, true. And there is for a machine running windows? Tacking on Cyberlink is not native support.That is way too much hardware for what it does, which illustrates how badly Windows is for a platform. You could do much better with less hardware. Which is the real problem with a htpc, the software, the operating system, and various codecs, and getting it to all work together. Too much complexity. Most of the processor is wasted on layers of software instead of doing actual work. Most of the effort is expended to compensate for lazy and inadequate programming, as well as DRM.
I understand the concept, I had a htpc for a couple of years, but after the frustration of trying to get surround sound to work in Cyberlink for Blurays, and the tech support to keep Windows working, I gave up. In fact it was specifically windows deciding to rebuild my music library from scratch every time I opened media center to play music. I want an appliance on the other end of the remote, having to search forums and break out a mouse and keyboard to trouble shoot something that worked the day before just fine should not be step two after pressing the power button.
In the the article, there is no details as to how much or little work it took to make the software environment to work. Did settings hold, did you have to do reconfigurations, update drivers, load codecs? I seriously doubt it worked out of the box. Working out of the box is the great failure of the pc industry. On the video quality you are hedging, saying that video quality will get better with driver updates? So it's not finished eh? That's the sad reality with the computer industry in general, nothing ships as a finished product.
The only thing this device seems to offer are endless possibilities to reward owners with a sense of accomplishment having solved issues preventing operations promised by the vendor. You can buy a nice bluray player, wd live, and still have 700 dollars for something else.
The real news is if you took it out of the box, plugged everything in, did a setup once, and spent the rest of the time using it. No drivers, patches, settings that reset themselves, or promises of a future update for something to work So what did it take to make it work like it's supposed to, what issues does it have? Did you listen to two channel, or full surround? How many error messages did you have to deal with?

What you are looking for is a player like the upcoming Netgear NTV550. That would put it in the media streamer section. That would be like $700 cheaper than the Vision 3D, but, with the NTV choice, you are at the mercy of Netgear for firmware updates in case something you want doesn't work, and it also doesn't support 3D -- which is what this product is targeted towards.. For the Vision 3D running Windows, you have a number of open source developers who can enable core features like HD audio bitstreaming etc. -- Try getting open source devs to get those sort of features working on a SoC based device.The fact with the HTPC scene is that you do have to do some setup of sorts and deal with error messages and what no. However, sometimes, slapping on the latest XBMC build solves most problems. Our test suite is designed to give problems to various softwares, so deriding drivers / softwares on the basis of the difficulty in getting it to work is not the purpose of the review.

Everything you state is true but, unfortunately, that can be said of computers in general. It's not limited to HTPC.You're also missing one of the major points of the HTPC: Its ability as a computer.
You don't get that from a standalone device.
You don't specify what version of MCE you were using, but if you weren't using the Windows 7 version it's not really a valid arguement.
I never tried the Vista version, but the Win 7 version has certainly come a looong way from the XP version.
And if you happen to be someone on a budget that wants to do it all with a single device, the price of the ASRock system is pretty attractive, even after adding the cost of the OS, monitor and BD software.

Pretty sure the hybrid Seagate Momentus XT is the fastest 2.5" drive they could have chosen. To all the other people talking about this egregious error, WD and Seagate are the only mechanical disk hard drive manufacturer's even worth looking at.
