ITS A SCAM ! said:
Are there a lot of Dreamboxes that need additional fans fitting ? My DM500s is a clone and sits on top of my PC Tower. I have never considered it hot enough to justify any additional fans. Is this design issue then ??
All electronic equipments get hot while operating and some even under standby condition.
In a hot country like Israel, I need to cool all my AV equipments with a ventilator on a stand, otherwise they will become quite hot and this can shorten their life.
In your case, living in the UK, a Dreambox might not feel that hot, but it is Summer now so you need to take care of it's becoming hot.
It is not a good idea to put it on top of the PC tower, as the PC itself must have nothing on top of it in order to cool down.
This way, the PC is getting hotter and it is also becoming an additional heat source for your Dreambox.
So my recommendation is to put it away from the PC, and if possible on a cool metallic object which can act as a heat sink.
