My new box, (only a couple of weeks old), has just developed a noisy fan. Am I right in reading that I can just disconnect the thing and it should be fine? I wont be installing a hard drive into the unit so is the consensus that theres enough room for the heat to dissipate?
Hi guys!
I've followed this tutorial and connected a 4" PC fan to a scart lead, and it only partially works: when I put the DM800 in standby the fan correctly stops but when I turn it on again, it does not start unless I manually give it a "swirl". Then it goes ok (until next stop).
Any ideas?
Thanks!!
this could be due to a voltage issue, if there isnt enough juice to get the fan spinning this could happen. its harder to get the fan started than to keep it going you see, not sure how you'd solve it though
hi was your dm 800 a sunray one ?
I was gonna buy one but it has the option of internal fan or external fan, so wondered whats the difference ?
I suppose the answer to insufficient startup current from the scart circuit would be to use a relay switch. More info if required at following http://www.autoshop101.com/forms/hweb2.pdf
I currently have a thermal switch on my TM800, the fan goes on and off even when in standby as the temperature changes in the receiver. The fan is quite loud. The relay option is better as the fan will not turn on in standby provided that power to pin 8 is switched off.
Get the 800se instead, internal fan no overheating problems

Is yours a noisy or loud fan ?
From Wikipedia (SCART):
Pin 8 Status & Aspect Ratio up[c]
0–0.4 V → off
5–8 V → on/16:9
9.5–12 V → on/4:3
Maybe pin 8 actually outputs only 5-8V when the fan needs 12? Would there be any way to force the scart to output 12V?
Also, if using a relay switch, where could I drain the 12V needed, on the DM800? Thanks!!
Did you do thisHi guys!
