Just wonrdering if 127 degrees farenheit is OK level for HR20 ?
There's been a lot of discussion in other threads about this. The consensus seems to be that 127 isn't bad and that the HR20 does not have a heat problem.thekochs said:Just wonrdering if 127 degrees farenheit is OK level for HR20 ?
I got the two-fan Targus model from Walmart online and I do use the USB port to power it. Mine runs from109-118. I didn't invert mine either, because on mine, the fans are reversed and the air blows out a slit in the back of the pad. It's called a chill mat.thekochs said:Just wonrdering if 127 degrees farenheit is OK level for HR20 ?
Why is it obvious that you don't use the USB port? Are you worried it might affect the machine? I use them and they do provide power.hasan said:There's been a lot of discussion in other threads about this. The consensus seems to be that 127 isn't bad and that the HR20 does not have a heat problem.
That being said, it was too hot for my "comfort zone". Mine was running 127 out in the open on a vertical equipment rack with plenty of space for ventillation. I bought a "cool pad" laptop cooling unit that has two fans (I think it's a Targus) and 4 USB ports. I just set it it UPSIDE DOWN (so it would draw heat out of the vent slots on the top of the the HR20). It is dead quiet and is AC powered (not USB). It dropped the temperature 20+ degrees and it now holds about 105 +/- 2 degrees and I feel a lot better.
My concerns are long term reliability and with nearly all electronics (and especially hard drives), cooler is better.
I obviously don't use the USB ports...I got the unit for its dual cooling fans and an additional nicety is that it is silver, matching the HR20. It was too expensive. I paid about 50 bucks for it...I think you can get the same thing hunting around a bit for half that.
No, not at all. Mine is AC powered...the USB is nothing more than a 4 port hub, unpowered. It has a wall wart that goes in the AC line to provide power for the fans. There are other units that are powered by the USB port, and I would have no reservations about using them in the back of the HR20.tstarn said:Why is it obvious that you don't use the USB port?

A man after my own heart! Mine went from 127 to 105 +/- 2 deg and I'm happy.Chimpo414 said:I am using an old laptop cooler that's too small for my new laptop. It pulls air out of the unit and plugged in the usb. Dropped the temp from 123 to 107.
Figured might as well put the cooler to good use instead of laying around
Very few issues in 2.5 weeks, but no MPEG-4/HD Locals here and that may be the source of some issues.lguvenoz said:Have any of you guys had issues with the HR20 and has the additional cooling helped????
I'm not aware of one longitudinal study of hard drives or solid state devices vs. temperature that would agree with your assertion that reducing the temperature of the operating environment by nearly 20% does not improve mtbf of virtually all components that produce or are subject to heat stress.pcates said:Mine runs 129 and I have no problems. So turn the heat up!
I don't know where the temperature sensor is and what it's accuracy it is but the value is going to be close PCB\Component temperature and not ambient air. Some sections may be cooler, some may be hotter. Internal IC temperatures could be hotter and they will be rated for 70 to 85 C. The boxes are in a fairly controlled environment so thermal stresses of heating and cooling should not be a problem. Is cooler better - probably - will it make a difference over the life of the box - probably not. If there was a temperature sensor in everything you own you would probably be surprised at how hot the ICs and PCB can be getting.
I have had only the BSOD issue, which is the blank screen frozen at 0:00 when trying to play something from MyVOD. Other than that, none of the other issues. Until today, when I started getting a blank screen/frozen box requiring a reset.lguvenoz said:Have any of you guys had issues with the HR20 and has the additional cooling helped????
I am just going to the quick menu, then setup and clicking on the top menu item highlighted on the left, info and test I think, and scroll down and you will see temp. It's not a dumb question by the way.HD-1080p said:How are you guys getting the Temp. are you just laying a thermometer on the unit or is there a thing in the menu that shows. The temp. Sorry for the dumb question.
