A300 Heat Issue?

A300 Heat Issue?
I have the A300 and after about 3 hours of playback, it gets extremely hot! Anyone else having this issue?

I do not have a hard drive installed in the unit.

Is it on or near other heat generating equipment, or on its own with plenty of space for air circulation?

RE: A300 Heat Issue?
It's designed that way.

It's designed to radiate the heat from the chip[ away through the heatsink and into the metal lid on the top of the player and through the vents in the sides. If it didn't get hot then the heat would not be radiating away.

You do need air space around the unit though into which the heat needs to dissipate.

RE: A300 Heat Issue?
the unit is in a cabinet and on top of a receiver. i think i will need to get a cabinet cooler fan for this issue and hope it helps cool it down a bit.

Like Chris said, it will run pretty warm/hot but I would recommend not having it sat on your receiver

On its own is ideal if poss.

Sat on a receiver which is also punching out heat over 3hrs or so is likely to damage the unit, or at least cause it to freeze/malfunction

RE: A300 Heat Issue?
Simple way to check the temperature, unless you have a good wireless IR thermometer:
Touch it with you bare hand... If you can handle the heat, it's below 60C. Normal for A300.

Mine overheated once while Copying 1tb of data while the A300 was on another component. I took it out of the cabinet and waited for it to cool down and all was fine. You dont want the heat from your reciever adding heat to the A300.

RE: A300 Heat Issue?
Hey, anyone know if putting an A300 on its side is a bad idea? There would be vents on the top and bottom that way and I was thinking I would set it upon something to get it a bit off the cabinet so there is airflow from the bottom. It would be next to a receiver but in a dual fan vented cabinet.... Guess I am bored and want to move some components around... Smile

RE: A300 Heat Issue?
The case is the heat sink, it's suppose to get hot and move the heat away from the chip.. then the added surface area of the whole case is used to have it dissipate instead of just a tiny little heat sink inside the case.. the vents are more for added air flow past everything offering faster dispersing.

but any cooling solution does require fresh air to move past the unit. If your not forcing air with a fan, you still need air to flow past it or your just turning the area it's in an oven and then you'll have heat problems.

Keep in mind all the components in these players are rated well above what you can touch with your hand.

RE: A300 Heat Issue?
Have the same problem - the unit hangs when it becomes too hot.
Am considering to add an additional heat sink on the outside, as i dont want a noisy fan (also i couldnt identify connection points where I could connect a fan - preferably temp. controlled)

How do you know that?

It could be a problem with the HDD or network. Do not jump to assumptions. 'Me too' posts are very dangerous as it makes you stop doing any investigation yourself.
You have posted nothing in your post to make anyone understand as to why you would think that heat would be an issue on a system that has worked well on the 100, 200 and 300 for heat dissipation without any fan and thereby fan noise.

Thx, I understand your answer.
Now we are one year later - and it is summer again (the temperatures just got again around 25 oC (yup - I live in Europe).
And again, the unit 'seems' to hang (no network issue, using HDD).
Set the unit vertical - improved marginanaly, bit it made a difference.
In the morning, no problems, only later. A300 is far away from other equipment (at least 50 cm) and on the floor (marble).

RE: A300 Heat Issue?
I have a C300 that got so hot that it stopped working, When you switch it off for some time it will work again.
Especially the HDD was very hot, too hot to handle, HDD's should be kept cool, or they will fail sooner or later.
Even when you put the unit in standby it will get very warm.

now I have a small cpu fan installed, it turns very slow and can barely be heard.
the unit is now cold and does work properly, you only need very little airflow. the output airflow is 5 dgC warmer that the room temperature.
One note: the cpu fan has a 3 pin connector that fits, but the pins are in the wrong order. You have to exchange pin 1 and 3.

So put a fan in the unit and your unit will last.....
These fans cost only a few dollars or euro's, mine was only 8 euro.
