| 728560 | 2008-12-13 08:53:00 | Go read about the crap cooling (or total lack thereof) of most routers on the www.badcaps.net forums and then come back and tell me that these cheap things are suitable for 24/7 operation... | Agent_24 (57) | ||
| 728561 | 2008-12-13 09:04:00 | Yeah man, esp those DSL-302g's, they're horrible :( I went through two of them coz one actually physically burned out from overheating?! I didnt know it was possible, but apparently it is :D *Eyes Widen* Wow, I've never heard a single complaint about them. I know the Wireless model is especially good. Go read about the crap cooling (or total lack thereof) of most routers on the www.badcaps.net forums and then come back and tell me that these cheap things are suitable for 24/7 operation... These Cheap things are suitablt for 24/7 Operation Why did I say that? Because you told me to :P But seriously, most people keep their ADSL Modems on all the time, and it's only once in a blue moon that we hear about one burning out.. some people are just unlucky I guess. Tell you one thing I miss about the DLink were the unintruding lights. The lights on the Huawei one are big and bright, and for some reason Orange=Connected and Green=Problem...... :yuck: |

| 728562 | 2008-12-13 09:20:00 | I know Dlink is a very bad brand as I had a few that had disconnection problem but havent heard of overheating problem | Ninjabear (2948) | ||
| 728563 | 2008-12-13 09:35:00 | Those cheap DSL-302G's are some of the most horrible routers on the planet! The DSL-504G's arent too bad though, but still not the best IMO. I avoid them like the plague, especially now Im in to VoIP a fair bit, none of those two afformentioned D-Link routers are really suitable, especially the first! |

| 728564 | 2008-12-13 09:45:00 | I never had a problem with my old D-link DSL-502T. I must have used it for over a year without any trouble, it was the Belkin router that made me get a Linksys and I didn't realize it was a combination modem + router until setup. Still use a DSL-502T on a different line. |

| 728565 | 2008-12-13 09:53:00 | so... Whats the difference between a processor and a circuit board that makes it different in terms of heat ? A modem does contain contain a chip that may require cooling? Uh still confused All of the modems/routers around do have a CPU - a lot run an OS of some sort - sometimes Linux, but generally something similar to it anyway. The CPU's are usually SoC (System on Chip) designs that may have built-in Ethernet, WiFi, USB, Flash memory, etc & are designed for just that sort of job. They're usually built on common embedded architectures such as ARM & MIPS. There's a lot of development work done on these types of chips to get the best performance-per-watt possible. They're run at slow (by PC standards) clock speeds (I'd be surprised if any ran much more than 200MHz) to keep power down & to give enough performance to do the job - after all, a basic DSL modem only has to process sustained 8Mbit/s or so traffic at worst. The newer gigabit/wireless-N ones probably use something a fair bit gruntier, but the performance per watt is still improving as the designs progress. Obviously they generate some heat - hopefully not too much - so do need to be located where some ventilation can get to them. Personally, I have a D-Link DI-624 that seems to get too hot when the wireless is running & it overheats & resets, but I'm a bit limited as to where I can locate the thing - my WRT504GL is fine in the same place. |

| 728566 | 2008-12-13 11:32:00 | I remember seeing some kind of paste in one of the past modems however I can't really remember what modem it was | Ninjabear (2948) | ||
| 728567 | 2008-12-13 19:37:00 | Power used turns to heat - more power = more heat. CPU's have millions of transistors each using a bit of power, it adds up (and cooks). Modems/routers are much less complex so they have more space to let air circulate naturally for cooling. However, for anything electronic cooler is better (down to quite nippy temperatures) for long time reliability. | R2x1 (4628) | ||
| 728568 | 2008-12-13 21:01:00 | Yeah I've got a Huawei Excholife wireless modem/router. It's on all the time and whilst it emits a fair amount of heat it doesn't appear to get so hot that I can't pick it up. Now the Cisco 3550 switch i have is a different story... gets pretty warm but the fans inside that one keeps things nice and cool. All I gotta do now is find things to plug into the other 19 ports which aren't been used lol :punk:punk |
