So... I suspect one of my 3825's either has a faulty fan, or isn't getting enough ventilation. I'm leaning towards faulty fan, simply because the router directly below it in the rack is fine. Regardless of the cause, it's a problem. After a few hours of use, ambient (room) temperature has risen by a few degrees (typical is ~73F, rough guess after a few hours, ~78, maybe?), and the fan starts to cycle between the normal low speed and high (note: it doesn't stay on high). The router is up 24/7, I'm using it as part of my regular network, which means when I'm gaming, all my traffic goes through it. I'm not sure if this is related, but lately I've been getting random fits of lag spikes. I still need to start doing some logging to see if it's just a coincidence and the problem is on the server-side, or if it's on my end. Based on the symptoms, the only two conclusions I can come to are either:
A) It's old, it got shipped halfway across the country when I purchased it, it's now defective. Fortunately, it's under warranty, so if that's the case, I can send it back.
B) Problems are caused by abnormally high internal temperatures due to poor ventilation, but not high enough to cause an auto-shutdown. Possible, but I feel less likely than option A.
So, my question is: In the interest of learning, and eliminating one of the two options... Is it possible to set up the router to log events such as high temperatures? If so, can they be saved locally (on the router), or will I need to set up a server to receive them? I suspect I'll need to teach myself about SNMP, but I'm hoping somebody with more experience can point me in the right direction (SNMP, or something else). I'm not opposed to setting up a server for network monitoring, I just need direction as far as what I need to be looking for. My Google-fu is weak. (I'll buy a book and read it if that's what I need to do, just tell me what book. lol)
(Theoretically, I could just check the environmental information via console every 5 minutes, but that would be a pain in the ass, and I wouldn't get to learn anything cool. So, here I am. >.>)
Random note for clarification, because I realized after typing everything that there could be some confusion between "after a few hours of use" and "router is up 24/7". The router is in the same room as my PC. The router is up 24/7, my PC is not.
