I was posting sometime ago about the MPU LED BLANK going off after some plays: someone suggested a heat issue increasing resistance. Well, there are some resistors that are obviously hot, and some ICs are hotter than others. i opened the back and put a ventilator in front of is. Issue is gone. looks like in these hot days (35c° in here..) there's a ton of head building up in there.
So i installed two 8cm, 2700rpm fans usb powered, sucking air fron the top holes and projecting down inside. 10 minutes work and 20 euro.
After a brief test looks like it's enough to keep temperature down. Will see how it develops.
i have no cooked areas on boards or cooked connectors or components, so apparently there is no major fault, but looks like it was just too hot inside with no proper ventilation.
