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.

Looks interesting at first, but I don't much like nvidia graphics cards, and the WD drive.WD drives are known to break right after their warranty expires when using them a lot.
The only good about the nvidia card is that it could be set up to work with CUDA (CPU + GPU in parrallel); although cuda now also supports most ATI/AMD cards.
The price of this setup is quite on the high end. If it wasn't for 3D vision, I'd say this computer would go for no more than $699. With 3D, I'd say $799 max.
I personally don't care if it supports 3D or not, since I have no monitors that support this resolution. So for me it's only worth $599.

They should have gone with a Toshiba drive instead. Yes, WD has faster continuous write and read speeds, but Toshiba is much better in IO performance.An OS like Windows 7 would boot faster with Toshiba, than with WD, and would run significantly cooler too!
WD is absolutely NOT the best drive they could have chosen! The cheapest perhaps yes.

Looks like the WD Scorpio Black is as good as the Momentus XT from Seagate (except for the Disk Capture benchmark):http://www.storagereview.com/western_digital_scorp...
So, from a price-performance ratio, it makes sense to go with WD.
I have also mentioned in my review that a mini-PCIE SSD for the boot drive would have been good :)

The best notebook drives were made by IBM, and now Hitachi. Whether that still is the case, who knows.Zok - Sunday, October 3, 2010 - link
CUDA is not supported on ATI/AMD cards. DirectCompute and OpenCL are, however, supported by both.LtGoonRush - Sunday, October 3, 2010 - link
Studies of both operating disk populations and drives sent in for data recovery show that no brand of drives is measurably more or less reliable than others, with the notable exception of the Seagate model ranges affected by their firmware bugs. It's also been conclusively proven that drive usage doesn't affect failure rates; lightly loaded and heavily loaded drives fail at the same rate. It's true that a failing drive will have its death hastened by heavy load, but you shouldn't be using a drive that's failing anyway, it should be replaced with the first SMART error it logs. The WD Scorpio Black drives in particular are the fastest notebook HDDs available, balancing high throughput with excellent seek times (Seagate drives have always had abysmal seek performance). It's also a little silly to complain about heat when we're talking about drives with sub-4W PEAK power draw.chrnochime - Sunday, October 3, 2010 - link
great job for correcting him without making it more obvious how wrong he is. I would've not sugarcoat it as much as you did though heh.lexluthermiester - Sunday, October 3, 2010 - link
Seriously? Not liking Nvidia, well that is just personal preference. You not having a TV/Monitor that supports what this system can put out is not the fault of the maker or the system itself, it your problem. But bashing WD? They make the finest hard drives in the world and there are certainly worse hard drive makers. Now I'm not going to be low class and name names, but really? And if you don't like this little system, then don't buy it, but don't bash something that certainly has usefulness to a certain audience of users and at a very fair price.Parhel - Sunday, October 3, 2010 - link
False. WD drives are not "known" for high failure rates. All drive manufacturers compare about evenly in most areas. WD is one of, if not the, best choice out there.Samus - Sunday, October 3, 2010 - link
I was a WD fan in the 90's and after the 7200.7's came out and they ditch the wetsuits I became a die-hard Seagate fan because of the 7200.7's legendary reliability, low cost, 5-year warranty and 'decent' performance. These were all big selling points during an era where the Deathstar 75GXP rocked the storage industry with what some circles were calling a "definitive" failure rate within the warranty period.The Seagate drives just worked. However, recently I've had a lot of Seagate 7200.10 and 7200.11 drives giving me SMART errors, specifically reallocated sector counts. They also run hot compared to my new WD Blue 1TB drive and they're all mounted in the same cage. A few years ago I had a 1.5TB Seagate I had to flash to CC1G because of the firmware 'recall' which was definitely a quality control concern. I didn't loose data, but I know somebody who did, one day their drive was just blank. We flashed the firmware and his data was back, but the drive failed after a few months without warning, just spun up and clicked. Tried freezing it. No dice.
Seems like WD is taking the quality/reliability crown, where as they've always had the performance crown...but performance wasn't as important to me as making sure the drive would work for 3-5 years without any issues.
I'd consider a Hitachi in the future, but will probably continue to stick with Seagate and WD drives. Considering how many dead Samsung and Fujitsu drives I've pulled and replaced from friends' desktop and laptop's over the years, it's a no-brainier to stay the hell away from those. Toshiba I have mixed feelings about because over the past 20-years, I just didn't care much for their laptops. Hypocritically, I love Thinkpad's but when IBM had those 75GXP failures, I didn't change my mind about their laptops, and still think they make the best laptop's out there. Ironically things are different now, because Hitachi makes the hard drives and Lenovo makes the Thinkpad's. IBM has little to do with either now.
