Hi
I noticed since first fired, the receiver Temperature was 55-59°C normally and this on my older glass open shelf.

Now within my new cabinet [obviously much more closed] it went up to 69°C [I DO NOT like].

I now managed to drill 8-10 2cm holes using my hole-saw + moved shelf down a bit and gives receiver about 6-7 cm on top.

It now seems to be 60-62°C - finally!

Anyone know the MAX Temperature s suppose to work with, so it will NOT die young ? Humax after 12 years still working, but it has a fan [having internal PSU].

I saw CPU only has a medium radiator and no fan!

Thanks

PS anyone know where to ge a circuit diagram?
I am an Electronics Technician and interested to see its circuitry on a diagram - if one exist.
