I don't know about the Roamio tuners but the Series 3 ones get pretty hot by themselves.

IMHO, with the base Roamio, the temperature that can be felt by grasping the coax connector is a lot warmer (borderline hot), compared to the Premiere or TiVo HD.

The other model Roamios kept the metal case and airflow of the Premiere, so I can only guess how warm they get. They do have two more tuners than a base model, and four more than a TiVo HD or two-tuner Premiere.

It's hard to make an apples-to-apples comparison.

I'm not very trusting of the base-Roamios design. The placement of the fan, the pull/push airflow, and all that insulating plastic (as opposed to heatsinking metal), just all seems so backwards to me. I do have a limited background in design and testing of cooling strategies. Unfortunately, I don't own my own rig with real-time monitoring, recording, plotting/graphing, and contact thermocouples to place on everything. All I have is my IR gun, which doesn't work well on shiny surfaces.

Only time will tell how effective TiVo's new design is, and what the longevity will be. For now, it's all speculation. The product hasn't been "in the wild" long enough to see how it will fare.

The only concern with the Basic should be if the fan stops working. Otherwise the design is fine. It does it's job keeping the airflow moving. It just isn't as efficient as the other Roamio models.

I can agree with most of that. I do have some concerns with how easy it is for the intake and exhaust slits to clog, and the choice of fan they used. Could they have found a cheaper, louder, and more inefficient one?

As loud and annoying as all three of mine have been since day one, I'm often tempted to source my own fans. I can't imagine tolerating what they will likely sound like when the bearings begin to go dry/wear out... IMHO, I just don't find the ratio of noise/airflow efficiency to be acceptable.

I use NASCAR-rated earplugs to bed, and can still hear just one running. Hearing two whining away, like mini jet engines, makes for some annoying nights. It's always the first thing I hear when I wake up, and can hear them with the TV volume pretty high, unless I'm watching an action scene.

But, I can hear sounds nobody else can. I can hear compact fluorescent lights with noisy chopping transistors, that nobody else can hear. Turn the light off, and I don't hear it anymore...

I'm on the look-out for an old 12v phone charger and computer fan for just that purpose.

Always recording? You're right. I did not know that. I wonder why the Tivo tech didn't mention that? Instead, he expressed puzzlement as to why it was generating heat even when "inactive" [his word].

I can hear any TiVo easily from 15 feet away in a quiet room. Every DVR is loud as far as I'm concerned. Fortunately I only have a TiVo mini in the bedroom now which is fanless. Although I don't mind the fan noise in the DVRs as much since its consistent. It's the hard drive noise that is bad. Especially with older hard drives.

If they weren't always recording there would be no way to have a thirty minute buffer for each tuner. Anything you watch from a tuner is being read from the hard drive, after it was written to the hard drive first.

I keep the top lid of my roamio basic off and have disabled my fan. As shown in temperature settings my temperatures have stayed the same l and I now have a silent Romeo.

Don't you still have a platter hard drive? Unfortunately they are not silent.

I'm using the stock hard drive. To me the fan noise was far more offensive than thehardrive sounds. The fan was a constant high pitch whine. Harddrive sound doesn't really bother me

Same here, except not using a stock drive. Fan noise far more grating on my nerves than any noise the WD Red NAS 3TB drive I am using ever makes.

I can hear the fan 12 feet away, with earplugs in. I have to use my left ear 4 inches away from the drive to hear it over the whining of the fan.

Now, put two of these in a small bedroom, with all hard surfaces, except the bed. I used to have four Premieres and two TiVoHDs in the same room, and wasn't bothered at all...

Things like this never get a consensus. Everybody has different ranges of hearing, differing sensitivity, and so on...

I've seen pages long segments of threads where the same drive is "silent" to some, "loud as hell" to others, and "just right" for the rest. Same goes for fans, and so on...

Lol! Ain't that the truth! And what's "hot" to me is "a little warm" to someone else.

picture quality

Sorry for hijacking this thread but are any of you DIY calibrators (with meters and software) and have found that the color on the Roamio is close but still off and at times you get what looks like bit rate loss probably due to compression?

The exact same settings are used on my Dish 722 DVR's input on my Samsung 64F8500 and the antenna input on this display and the picture looks better.

Jim, that's WAY out of my area of expertise, but I'll venture a wild guess that it's a matter of your Samsung having a better tuner than the Roamio. Hopefully, someone who actually knows something about this will chime in

BTW - Interesting question - (and though I don't know the rules or etiquette on this forum regarding theadjacks, I certainly take no offense).

Calibration has nothing really to do with it. You're talking about the broadcast technology being used, and the quality of it (compression, etc from cable QAM, DISH's satellite RF modulated MPEG2/4 and OTA ATSC).

For clarity....I'm referring for off air reception from 3 different devices...coming through Tivo compared to Samsung F8500 off air tuner compared to Dish 722 off air tuner. The F8500 and Dish 722 off air tuner are very similar in picture quality with more color gradations and what appears to be slightly more accurate color when compared to the Tivo. This is with a traditional calibration. Although I've been doing LUTs calibrations as well, I've not compared the 3.

Every device is different. You have to do a basic calibration and then tweak it to the specific device. Even two devices that are the same model can have slight differences.

I had been getting professional calibrations since 2001. Usually once or twice a year. I always waited until I added a bunch of new devices before I got a new calibration so it could be tweaked for each device. I do the calibration myself now, but I'm not trying to do all the specific devices like in the old days. Especially since I have too many of them. So I get the basic calibration done and then tweak it better for my BD and media players.
