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 a bunch! Based on this, there's no major hangups so I'll be looking to get one as soon as it's available from newegg.cjs150 - Tuesday, October 5, 2010 - link
Bit like the Apple TV article, we are moving closer to the ideal living room HTPC but not there yet.A decent SSD rather than a HD would be better, less noise, reliability not an issue, less heat.
Noise is the issue for me. This is improving (and would be less noisy than my current cable box) but still not perfect (total silence would be perfect but impractical).
I do wonder whether an optical drive is really necessary. Seems to me that there may be 2 HTPC markets. One for a streaming device that can play games and another where the device is also the sole Blue-ray/DVD player on an AV system.
I would be happy to ditch the optical drive for a TV tuner. Even more so if it could replace the cable box

Dear Ganesh,Is its BD playback video quality better than consumer BD 3D player?

I didn't do a side by side comparison, but I would believe that you have lot more tweaks available at your disposal on the HTPC to do some post processing if you desire (compared to the options in a consumer BD 3D player).The only advantage of a consumer BD player I can foresee is the ease of use factor. HTPCs are inherently not designed to cater to the lowest common denominator yet. (Yes, we have Win7MC + PDVD / ArcSoft integration, but you still need to do some configuration like AutoStart / Start Maximized / configuration of 3D display etc. etc. to make sure it acts like a consumer BD 3D player).

With my current HTPC, I can have distinct On and off Codes. so my question is this:You said you can wake the HTPC via the remote, but can you
1) put it to sleep with the remote, and
2) Turn the computer on with the remote (from an off state)
3) program additional codes for the IR Receiver (for instance, I have a button on my universal for alt-f4)
Neither are ultimately important, but I like my setup as it is now (especially since I can train specific on and off codes for my IR Receiver for the HP)

1 and 2 are definitely possible ( 2, when AC power cord is still connected, but you already knew that :) )As for 3, I will ask ASRock. I haven't personally tried out.

If this were an Asus brand product I might find it more attractive, but I think ASRock has issues with its reputation. I mean they make some innovative and low cost mobo's, but from reading around they seem to have quality control issues. Last time I visited their website they had imperfect English so I think I'll just stay away.mutarasector - Monday, November 29, 2010 - link
Can't wait to see a Llano powered version of this thing. I believe one might see a mini based on it by the 'Fruity computer Co.' in the not too distant future.borekb - Tuesday, February 1, 2011 - link
On these screen-less HTPC devices, how do you display things like MP3 or volume information while you're playing musing and the TV is turned off? I'm thinking about attaching a digital picture frame but would that be possible to output the signal to both HDMI (-> A/V Receiver -> TV) and to the frame? (I don't own any digital picture frame at the moment so I'm not sure what would be required on that front.)mpogr - Thursday, June 2, 2011 - link
Got one of these. They sell them here in Australia without memory and HDD, purchased both from the same store, the total price was ~940AUD (should be ~970-980 USD now)..Assembly was quite easy and all was working fine at first. Installed Windows 7 Ultimate 64 bits, SageTV client and PowerDVD 11 (planned primary use: TV and, occasionally, 3D Blu Ray playback). Because of TV being used by the children, the computer was always on (but not always playing back media). The unit died after ~5 days. I wasn't at home when this happened, but it just powered itself off. After that, upon disconnecting and reconnecting power, it came on and then off straight away. Resetting CMOS and pulling the BIOS battery out helped a bit, so now it doesn't power itself off after reconnecting the mains. The blower spins and the power led is lit, but no video output and no HDD activity. Disconnecing HDD and ODD didn't help.
So it's just dead. It can be the unit itself or the memory, as I don't have any spare SODIMMs to test. About to send the unit back to the retailer for investigation.
