Internal Temp range for Series 3?

I have no idea what the max temp is, but I can tell you that mine runs at about 48 degrees C in a 70 degree F room.

My S3 typically runs anywhere from 42C to 46C in 70F room.

 

I think the max temp in spec is 55C. I've never seen mine go above 50C.

 

Yep, that's right where mine runs too.

 

Mine is running at 42C in a 64F room.

 

64F? Brrrrrr...

I just noticed that my Series 3 is running at 51C (123.8F) which is a lot higher than my Series 1 which is running at 37C (98.6F). We had an abnormally warm day here so it's 74F now (64F outside).

I'm a bit concerned about the higher temperature and the effects on the disk drives longevity, but looks like the disk drive is rated for 41F-131F. The Series 3 does run substantially hotter than both of my Series 1 units in the same location.

Footnote to my previous post: my S3 was at 40C this morning which is the coolest I've ever seen it. But normal range is 42-46C in a room that ranges from 60-72 degrees.

 

Mine is usually around 46-47C. I'm in Florida, so room temp is typically 73-75F during the day, when we're not having a cold front.

It runs about 4 to 5C higher than my early S2.

And I haven't installed it in a cabinet yet; it's just sitting on a table near the TV.

 

my s3 with an upgraded 500gb drive runs at 46c outside my cabinet, and as high as 58c inside a cabinet with no exhaust fan. i have installed an exhaust fan and it now runs at 50c. btw, when it was at 58c, it stated it was still at normal temps.

 

My three S3 units range from 42c to 46c in 72F rooms. The one that sits on top of an HR10-250 is the hottest at 46c.

 

I actually searched to find this thread for the same purpose. Mine is located in a cabinet and with the door shut it runs around 48c and up to 50c when watching on the big screen with the receiver on. I guess I'll not worry for now.

 

Mine runs at 51C in the cabinet (doors closed) and at 47C when the doors are open.

 

My S3 is at 46-49C in an open front cabinet with room temperature at 64-70F.

I was thinking I could drop the internal temp a couple of degrees by piping the exaust air from the S3 fan out of the cabinet. I haven't figured out a what sort of duct or tube to use and how to secure it to the back of the fan grill. Any ideas?

 

My S3 boxes run at about 46-48 degrees and are mounted insde a cabinet with an open back. Ambient room temp is 75 degrees. I have two of them one stacked on top of the other. The one on top runs at the same temp as the one on the bottom. That wasn't the case with my old DirecTiVo boxes. So the S3 seems to tolerate "stacking" better than my old ones did.

The box itself feels quite cool compared to my old DirecTIVos. I think the geeks at TiVo came up with a better cooling system in these boxes. It's also much quieter than my old boxes. All I can hear now is the Comcast DVR chugging away... I can't hear the TIVo boxes at all.

 

I used a 3.25" diameter mailing tube, with enough length cut to fit precisely around the fan/exhaust port on the back of the S3 and the the back of the cabinet - in effect creating a dedicated "tunnel" for the warm exhaust air to exit.

This reduced overall internal temperatures by an average of 2 deg C. Glad I did it, it's invisible, cost nothing but the effort to cut the hole in the cab. and the length of tubing.

Piece of Cake. Go for it.
