I posted a few weeks ago about my temps on my 722K. I just checked and now they are at....

High 140
Low 112
Average 122

Nothing is blocking the air path. Fan sounds normal. At what temp will my 722K melt into a blob of plastic or when will the internal temp shutdown the unit.

Those temps aren't particularly high. A bit cooler would be better, sure. Is it in a cabinet or on a shelf that impeads airflow?

It is sitting on top of the entertainment center. Nothing is around the unit that would prevent airflow from passing into the unit.

What is the ambient temperature? The temperatures inside electronic equipment typically are some number of degrees above ambient so as the room gets hotter (warm weather is now upon us), the temperatures of our equipment will tend to increase proportionally.

Ambient is in the mid 70's in that room. I was just curious since it jumped higher than my last readings a week ago.

You do have to give the OP credit though. He has been a prolific thread starter, with some interesting Titles.

Ah, but for the folks who don't have a fireplace on those cold winter nights, a ViP DVR makes things warm and cozy....

And the 722 is a "hot" receiver ... but now we've spent more posts discussing the title than the temperatures how effective is the title at getting answers?

I'd set a thermometer next to the receiver (but not in the path of the exhaust air flow). See how hot it is outside. My 622 is running at 118-138 (mean ave 132). It could use better airflow.

On top of makes me think of heat from other equipment affecting the 722's temps. Is there any other explanation (sunlight, etc)?

Thermo says 76 in the room next to the 722. No other equip is on top or next to the 722 and their is no direct sunlight. Other than that I find it odd that it jumped several degrees within the last few days. The unit is normally on for about 8-12 hours per day.

Is this causing you a particular problem?

When I upgraded to HD and saw the temps on the 722K I was a little worried. I went on Ebay and bought one of those notebook coolers.
The trick is picking up the 722 and sliding the cooler under the bottom without breaking the flimsy cooler. Worked really good. Mine has 3 fans that are blowing up through the 722. It's a USB powered cooler so I bought an adapter to plug into the wall for power.

How long does it take for the values stoered in memory to change?

All things being equal... the temperature is going to change from day to day depending upon how you use the receiver.

The hard drive is spinning all the time... so that's a constant... but there'd be a heat difference in how you use the drive from day to day.

I have to think it runs hotter if you are recording/playing from all the possible tuners at the same time, than when it is "resting" and just being watched.

Also pausing and trick play should exercise things more than just the normal default buffering that happens when watching live TV.

Also, while the temp is a measure of the hard drive... that temp would be increased by use of the receiver in general... so when the CPU is running hotter, the hard drive might be seeing that heat increase too.. so basically, lots of factors go in to what effects the temperature.
