HR24-500 111 degrees on an opened glass shelf
Not sure, I think it is. I know if you take out a stock HDD from a 20-700 and stick in an EADS or an EARS the temp drops to 118 degrees. Also if you put an external device on a 20-700 it drops the temp reading to 118 degrees.
A few years ago, if you put an external drive on a 21 series HR it would show the temp at 77 degrees. That temp would never vary, so I assumed it was the default temp reading. I'd guess the 20-700s and the 21 series HRs have different ways of reading the temp.
Didn't you also get low numbers when it was unplugged?
Might be that when the 21 is using the external, there isn't any heat in the internal drive [where the sensor stays].
HR22-100 99 degrees on a glass shelf.
No, without the external HDD, the temp read what the 21s usually did. There was also a way to get 0 degrees. I'm trying to remember when that happened. A little help from someone!!!
So, if the sensor is on the HDDs, that would explain the 118 degrees I see on my 20-700s with EADS or EARS HDDs no matter if they are external or internal. Am I on the right page here?
I can only tell you what mine run. Location and proximity to other A/V components play a large role in receiver temperature.
My HR21-100 runs about 117°.
My HR24-500 runs about 111°.
Think you're on the same page, and "without" the 21 external drive it reading "usually", doesn't this point/suggest that when the external is being used there isn't any writing to the internal, so it isn't getting warm?
IIRC: 0º was when you have the internal cable disconnected.
My HR23-700 with a 2 TB WD20EADS runs at about 126 Degrees so Rich maybe you have explained why mine runs so Hot.
It is the WD20EADS being added to the HR23-700 that makes it run Hot!!!
It would also make a difference if the drive is a 7200 rpm drive vs a 5400 rpm drive.
I have not tried out an external drive yet although I've had a blacx bay since last September sitting in my computer rm.
My WD20EADS spins up to 7200 RPMs so maybe that explains why mine is so Hot!!!
Also, when I used the External Hard Drive Enclosure I registered 77 Degrees and I was told by someone knowledgeable that this was a Default Temperature Reading that did not vary as it was a Constant Default Setting.
I'll admit this whole external/internal and temps thing has always puzzled me. Logic tells me that if I put an external drive on an HR, and the sensor isn't on the HDD, the temp of the internal drive and the temp of the external drive should cause the total temp to rise. Even tho the internal is not writing or being written to it's still spinning and that should create heat. The sensor must be on the HDDs. That means that, at least on the 20-700s, the temp of the internal drive is ignored and the external drive only is read.
Damn. I ran a 20-700 without an internal drive for months and I can't remember what the temp was. Or if I even checked it.
The EADS make my 20-700s run at 118 degrees. Normal temp for a 700 is 123-126. Your 23 should be running cooler, not that 126 degrees is gonna hurt it. Your 23 was up to over 140 degrees at one time, wasn't it?
I'd buy that if my 20-700s with the EVDS drives in them or on them didn't read 126 degrees. And the EVDS was produced for DVRs. Wouldn't you think they'd run cooler? We've had threads about the temps before and they really get confusing. I'm getting kinda fuddled already....:lol:
I had a long conversation with a Case Management agent a couple years ago about that and he agreed with my opinion that 77 degrees was the default temp. But then some folks posted that they were seeing 0 degrees and that screwed me up. I don't remember what was done to get the 0 degree reading, but I do remember reading about it.
Have you verified that the fan is working properly? If I knew where my 20-100 was I'd check fan location, but the 20-700 does have the fan mounted vertically inside the chassis n looks like it flows from sideways, also i think its a 60mm fan not positive on the size. You could try a higher cfm fan in there.
My 20-100 though ran at 127°f constant with no artifacting on the recordings.
My 34-700 is 106° open air at about 70-75 ambient
From what I recall, it Registers 77 Degrees for Default Temperature Readings if an External Drive is Connected and 0 Degrees if the Internal Drive is Connected.
126 Degrees is the Highest Temp I have ever had on any DVR and I use to have 118 Degrees with the HR23-700 before I added the 2 TB Drive to it.
I have 2 24's stacked inside a cubby hole where the old 20-100 was.
The 24-500 is 118° and is on bottom. The 24-100 is 111° and is on top. Bout 70 ambient.
There's nothing wrong with the temps on any of my HRs. But when you add HDDs and the temps drop, I think it proves that the HDDs have heat sensors built into them and the HRs read the dominant HDD. But I could just be thoroughly fuddled about that....:lol:
Tell me you have at least a 1" spacer between them.
