Cooling

Cooling is one of the most important aspects of any chassis and most importantly, cannot be cut out of an HTPC case. Though smaller than a mid-tower chassis, an HTPC case, in our opinion, is required to have more than adequate cooling, since audio/video encoding and decoding could become highly dependant on the CPU, which, in turn, could cause temperatures to rise significantly.

Though sticking fans around the case would not be a bad idea for a mid-tower that we can stow away under a desk, an HTPC case needs to be as quiet as possible, especially if it is to be sitting next to your television among other components. No one enjoys the humming of case fans while watching a quiet film because it distracts attention away from what we are viewing. There are methods of keeping an HTPC case quiet and some come with these features directly from the manufacturer.

Ahanix has included a quiet power supply rated at 350W, which can significantly reduce noise levels. We were a bit worried when we saw that it did not have a larger fan at the bottom to help exhaust air from the case, since there were only two other 60mm fans installed at the back of the case. We do not think that this cooling hardware will be enough to keep down temperatures of the warmer running components, but we will leave that to our thermal benchmarks.

    Heat and noise are the enemies of an HTPC. The temperatures displayed in this test seem exceptionally low for what I've seen reported by others, usually around 55c. Try this with an Intel CPU or a "slimline" case and see what happens. The 520W Powerstream is overkill. Also, where is the TV tuner? It needs a Hauppauge PVR-250 to make this a real HTPC.

    When can we expect to see a more comprehensive review of HTPC cases?

    Some interesting units out there on the net that would be good choices for review, IMO:

    http://www.atechfabrication.com/
    http://www.ahanix.com/ (other newer options)
    http://www.silverstonetek.com/

    And especially the new HT-400 from:

    My recent purchase of an HDTV puts me in a position where an HTPC would be useful, but I don't think some of the things I intend to do are considered in this review. Some things were hit on however, and I hope to see more cases with these features.

    1. I need LOTS of storage. Archives of my HD Tivo will take up quite a bit of room.
    2. I want to play games on my 62 inch TV, so I need thermals for serious video cards as well.
    3. The IR reciever for remote is nice.
    4. The ability to have an LED panel acknowledge commands from the remote, display track/time of a movie etc. Also, the ability to dim during movie watching so as to be less of a distraction.
    5. Silent Cooling.

    "Another feature that Ahanix has managed to implement, and others should follow suit, is the IrDA transceiver"

    I can't see anything like a IrDA transceiver in the pictures, and I can't find any info on Ahanix's web site with regard to built-in IrDA capability. Someone please clarify.

    Amen. Why make it seem like the temperatures are a problem when they aren't? They aren't even close. Perhaps the review has to appear 'balanced' but surely perfectly normal operating temperatures shouldn't be given anything like the same weight as ease of access, noise levels, and aesthetic considerations. When normally-clocked HTPCs actually start failing because of heat from poor ventilation or Johnny burns his hand on the case, then it's time to talk about "thermal issues."

    The thermal testing is nonsense. An HTPC places noise control a lot higher in importance than thermal load. The temps quoted are nowhere near the level of causing a problem with any of the components. My HTPC has run for several years with less fans than in the article with absolutely no problems. As long as the PC is stable I couldn't care less if the temperature was 500 degrees inside.

    Case I use is here btw http://www.kanam.co.kr/html/htpc.htm

    I'm glad you guys are spending more time with the htpc market. I'd like to see a review of silverstone's htpc case. I'm getting ready to drop a lot of money on a new entertainment system (plasma, htpc, and the works), and just want to make the right decision. I'm very interested in the lc02 (black: http://www.silverstonetek.com/products-lc02.htm) with a matx setup, but all the reviews I've read try to fit a full sized mb with all the xtras (unecessary if you ask me). I think that something like this with a mobile processor (mobile athlon 35watt probably) would be the best setup.

    I think that AnandTech's thermal tests very much need expansion for HTPC cases. Very few people will build a PC in a case like this and then leave it freestanding. Rather, HTPCs will be stacked on (or even under) other home theater components and are likely to be installed in cabinets closed at the rear without fans in many living rooms. Testing the cases' thermals in these situations would be very helpful to many of us. Also, recommendations such as, "Put a fan pulling at least 25CFM behind the right-hand side of the case when installing in a closed cabinet and do not operate an HTPC installed in this case without its being open at the front," would seem especially useful. The alternative is either trial and error or component failure for many users.
