PIX506E running really hot

Ok, this is the 3rd "brand new" 506e unit that I have come across that runs really hot right over the CPU. So hot in fact, I cannot handle the unit on that spot without burning my fingers.

I also noticed when I opened the unit up, is that they no longer come with a fan on the front plate of the unit. The first 2 506e's I came across I believe had those (or at least the 506s), and although they too ran hot, they did not run as hot as this one.

Can this be normal? 3 for 3??




Re: PIX506E running really hot


Indeed, the PIX 506E runs hotter than some people expect. However, this is not dangerous to the unit or to the surroundings. It has a thermal shutdown circuit which will shut it down if it gets too hot. The problem is that the bigger CPU's on the 506E have a larger heat sink which is closer to the top of the case. This gives the illusion that the unit is running hotter than a 506. And yes, you are correct that 506's had a fan on the front plate whereas the 506E's do not. This same issue has come up in the past and I assure you, this is not an issue to be concerned about. Hope this helps.
