HTPC enthusiasts are rightly concerned about the noise factor, heat and power consumption, ease of usage and many other criteria. We will tackle each of these concerns one by one in this section.

Noise

ASRock doesn't make any claims about the quietness of the system in their marketing material. We were pleasantly surprised upon looking at the noise reports. In the set of pictures below, a professional sound level detector was placed less than 2 ft away from the CoreHT, and the sound level measurements were taken in various HTPC scenarios. The unit has a noise level of less than 36 dB at full load (for both CPU and GPU). In this respect, it is actually similar in performance to the earlier SFF HTPCs from ASRock.

22.4 dB at Idle

27 dB during Disc Playback

35.5 dB at Full Load (Prime95 + Furmark)

Power Consumption

In order to get an idea of the power consumption numbers, the Prime95 and Furmark benchmarks were let run overnight to keep both the CPU and GPU completely loaded for an extended duration. Under these extreme conditions, we found the average power consumption to be around 62.8 W. At idle, the average power consumption was around 18 W.

These type of power consumption numbers have been enabled by ASRock's choice of going in for a notebook platform instead of a desktop configuration. This has resulted in a smaller form factor case design for the mini-ITX motherboard. Since there is not much heat to be dissipated, the cooling system is also appropriately small and silent.

Ease of Use

HTPC enthusiasts are concerned about how easy it is for their system to come out of standby. Existence of HDMI handshake issues upon return from standby is also a deal breaker for many. Fortunately, the CoreHT 252B has no issues in these two aspects. As long as the AC power adapter is connected to the system, the bundled MCE remote can be used to boot the system (even if the PC had been shut down previously). In order to shorten the boot times, ASRock supplies an Instant Boot utility. Using this, whenver the CoreHT is shut down, it boots up once again and shuts down before the power can be safely removed. Upon power up, the boot up is instantaneous. The MCE remote can also be used to bring the PC out of sleep mode.

Power users can also take advantage of the AXTU (ASRock eXtreme Tune Up) utility for greater overclocking control.

Within Windows, the MCE remote can be made to work with a variety of applications such as XBMC, MediaPortal, MPC-HC and of course, Windows 7 Media Center. Blu Ray players such as PowerDVD and ArcSoft TMT can also be controlled with the help of the MCE remote. For the ideal I/O scenario, one probably needs to purchase a wireless keyboard / mouse combo.

    "if you are a stickler for image and video quality, go with AMD, and if you want the best of freeware / open source software to do the work for you, go with NVIDIA"

    Ganeshts, what system would you recommend for Linux + XBMC then ?

    I none integrated solution would be my suggestion. But pure XBMC machine you would probably get by with ION-NG or the like. But for a moment disregarding that. You can't get a decent CPU (still some need for software decoding, or transcoding) and a decent GPU (that can do video decoding and postprocessing or well drivers to handle OGL and VDPAU in XBMX/Linux case, as well as audio properly) otherwise. I'm sure Ganesh can agree on that point.

    That means that there are a lot of options and combinations as well as cases, sizes and so on. But don't expect stuff to be trouble free anywhere when it comes to stuff like this.

    I think hitachi cinemastar hard drives might have been a better pick due to their claim of quieter, lower power, and 24/7 operating abilities. Reply

    The lack of a TUNER or CABLEcard Slot or even a free pci-e slot for DVR use makes this HTPC a tad less appealing. Reply
