Just wonrdering if 127 degrees farenheit is OK level for HR20 ?
Earl, what is the upper limit for temp that that D* is telling you ? Also, is this reading on INFO/TEST the ambient in the box or what ?Earl Bonovich said:127 is the normal operating temperature for the unit.
I agree with you on the HDD 55C limit...some of the Maxtor CE drives spec 60C though. However, I'm guessing the CPU is not measured but maybe the HDD. The CPU is not running that many MIPS in these boxes.....maybe 300-500 or so but the HDD is the biggest point of failure so my bet is the temp is the HDD. That said, sure is pushing the limit at 131F. Also, when I playback recording the temp rises, live TV it drops to 125F.harsh said:131 is the upper limit of the operating range of a hard drive. If the ambient is that high, I would think that the top plate of the hard drive (where the temperature is measured) is hotter than the 55C limit.
I'm inclined to think that the temperature is actually the CPU temperature.
Now we know that the thermometer goes above 129!
Good point !!!!! Scratch that request D*. Guess Standby isn't a power state like in a laptop...huh ?paulman182 said:"So, switches based on a thermometer. I've never tried but with these starting up at 70F I'm not sure how well they would work. Personally, I'd like to see D* turn off the USB port power on standby mode....this would be nice turn the USB powered coolpad off.....hope they are listening."
Thanks for the informative post...but I hope they are NOT listening.
I'm not using a USB fan--mine is a lot bigger, sucking air out the top--but the HR20 runs the hard drive, and generates heat, even in standby.
If someone were using a coolpad on top of the HR20, it had better stay on at all times, or it'll trap that a lot of that heat in the HR20.
Check the temp of your HR20 when you come out of standby and you'll probably find it is as warm as when it has been on for a while. If the fan is needed at all, it is needed anytime the HR20 is plugged in.
They do......it's a part of the SMART functionanlity in a drive. There is a device called a Thermistor that measues temp and thru the SMART interface (which monitors much more than temp...example bad writes/reads, etc.) tells the system there is a threshold violation. It's up to the firmware/system to decide what to do at that point. CPUS like Intel Px, AMD, etc. have these on-board and they cycle back clock rate and/or shutdown.harsh said:I too am guessing HDD because most modern drives have built-in thermometers and, as you said, it is the critical path.
