RE: [mythtv-users] OT: unplugging the fan of the grafic card
Yann asked I am planning to build a MythTV system, and would like to install a NVidia grafic card for software decoding of the recorded shows. The newer cards almost always have active coolers (with fan). Does software decoding use the heat producing features of the gpu, and if not, can I just unplug the fan to get a silent system ? A little late but wtf, fwiw my mx440's fan has died, seems to make no difference (apart from being quieter ;-) ) and not noticed any problems. Personally I'd suggest just get one with out a fan in the first place. Druid ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Or you could replace the default fan and heatsink with one from zalman - in 5volt mode they are silent (thats on a geforce 6800gt)On 10/31/05, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Yann asked I am planning to build a MythTV system, and would like to install a NVidia grafic card for software decoding of the recorded shows.

Thank'sYann FWIW I have a GeForce2 that I unplugged the fan on, but that was only because the bearings seized.

All features will produce heat, but most generic rendering of images isn't going to be terrible for it. I don't know of anyway to underclock your video card for Linux, but if you could it'd help. If you keep relatively good airflow in your case and don't drive your card too hard with games or such, you very likely will be alright. You card will most likely not live as long as it otherwise would, but many people, like the above, haven't had any problems. I recently unplugged mine after looking at Zalman's passive coolers. I have a Zalman on my gaming machine and am very satisfied with its performance, but for me it was simple math. If my card happens to burn out, a GeForce MX4000 is $30, and so is the Zalman cooler. Obviously, if I needed more than s-video out, that could change. Your math may vary. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] OT: unplugging the fan of the grafic card
In general, the fan is there for a reason. If you unplug it, it might fry. Whatever you do, never run it without a heat sink. I suppose you could monitor the temperatures with an infrared thermometer and try to see if normal myth usage will get it that hot. You might also be able to find a passive heat sink that will do the job in certain cases. directron.com? Of course modifying the card will likely void the warranty.. Also, you may be able to find a quieter fan, or possibly run the fan at a slightly reduced voltage. Be careful with reduced voltages, since if you get too low the fan may not reliably start. Obviously with a reduced voltage the fan spins less fast and you get less cooling.. Personally, I'd look around for a card withoug a fan. For SDTV even a Geforce 2 MX would likely work. For HDTV you might need something a little faster, but I suspect you could still find one. The radeon 9000 I have in my myth box is decent and it has a passive heat sink, although most people seem to prefer nvidia here, since the driver support seems to be better, particularly if you use tv out. I suspect the 9000 is fast enough for hdtv, but well I don't have an hdtv source yet, and my amd xp 2000+ probably isn't anyway. -Robert On Thu, 2005-10-13 at 09:56 +0200, Yann Lehmann wrote: I am planning to build a MythTV system, and would like to install a NVidia grafic card for software decoding of the recorded shows.

I think that most of the low-end nvidia cards (e.g. 6200) do not have a fan, and they would probably be enough for MythTv. I don't know whether there's a difference in the quality of Tv-out between low-end and high-end models. -- Vladan Bato [EMAIL PROTECTED] ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Yann Lehmann I am planning to build a MythTV system, and would like to install a NVidia grafic card for software decoding of the recorded shows. The newer cards almost always have active coolers (with fan). Does software decoding use the heat producing features of the gpu, and if not, can I just unplug the fan to get a silent system ? I wouldn't recommend that. I use an FX 5200, with HD resolution, DVI output, no fan, and it's cheap ($60 U.S.).
