We’re thinking of upgrading most of our “tower routers” currently running RB1100AH’s to the new CCR’s, likely the CCR1009 series. Notice there is a fan-cooled VS passive-cooled versions. Anyone have any suggestions on which one would perform better in extreme temp ranges? I see the spec sheet for temp shows a drastic difference when comparing to the RB versions, our tower routers are mounted inside an outdoor enclosure, so it will trap some heat that is given off from power supplies and equipment, but temps could range from below -4F in the winter, and perhaps +120F inside the box during the summer.
Passive, or fan-cooled? Any have a wider temp range for extreme cold or heat?
What matters more is the ambient temperature. If you have fans on your enclosure go with the passive one. The PSU will fail if used in high ambient temperatures for too long. The passively cooled CCR has heatsink that goes all the way out so would be more effective at cooling only if there is fan outside.if you dont have any fans than go with active cooling.
Thanks, that’s what I thought too, but had mixed opinions about it. Our NEMA enclosure boxes are not vented at all, so they get extremely hot inside. I was more worried about the cold temps, which in this case the passive cooling would maybe be better. But during the summer, the inside of these boxes with the sun baking on them all day can probably get over 120/130, with all the other gear putting out heat as well, etc.
Yeah I would reccomend the actively cooled models.
They can at least spin the fans up to cool themselves down if they get too hot.
