I have the same temperature,i just have simple solution for these,buy a cheap 10$ fan and aim it to the 450g ,gone into 45C.What is normal operating temperature of RB 450G? According to System Health monitor my RB is 60-65C. Is it normal, or maybe dangerous? There is no special ventilation, but nothing is blocking the vents on the RB box as it stands on a shelf.
680 Mhz is the factory default speed. I would expect more cooling would be required to work stable at a higher speed.mine is not working stable at 800Mhz
The temperature sensor is on a hot part of the board, possibly on or underneath the CPU. The temperatures will be higher than the ambient air.What is normal operating temperature of RB 450G?

I believe this is operational temperature - so this numbers are for environment outside the router. I don't think that -20C is possible inside the 450G without any additional coolingI think I would worry and actually worry a lot since the RB450G is suppose to work up to 45C according to this:

that's the outdoor air temperature, not the board temperature!I think I would worry and actually worry a lot since the RB450G is suppose to work up to 45C according to this:
It is not very clear though if that is the ambient air temp in the box or the sensor's temp and where the sensor is located at. However, even if we assume the sensor's location is inside the CPU, 55-60C is still a pretty high temp to run without any load whatsoever.
So, no "rules of thumb?" 10% margin of error? 30% margin of error? 10% margin at 20C, 60% margin at 25C, to be ridiculous?did you see any problems at the 80C temperature reading?
the temperature sensor is not very accurate so do not trust only that.
where is placed temperature sonsor on RB450G?some more intersting info
This router is so important, I cant even down it for a minute and we get in trouble with the banks voip, waiting in christmas to replace it sometime
just noticed this now on the 450g, cpu peaks to 100% easily at times, pushes around 3M of g729 voip thru with around 30M of data concurrently, i see no issues so far on it, but growing pains would require upgrade soon i guess
the RB450G already has two power jacks (one inside the indoor case, one outside)there is no room for a fan inside so you need to make some modification to the case or watever. if you know what are you doing you know also to solder a jack to the board,or split the power cable, am i right?
Hi NormisThis is not high. Your device doesn't need fan. RouterBOARD can work perfectly until the CPU shows 70-80C.
