Upgrading the fans in a Cisco 2821 Router

Hi,

I run around 4 Cisco 2821 routers with PVDM cards in handling all my voice data. I've noticed on two of the units the fans have died.

I was going to buy a fan replacement kit from Cisco at a cost of around £40.00 but when I took one apart I noticed that they ares tandard 80mm 12V fan units.

I'm considering now upgrading these from the standard fans that Cisco ship, to a couple of standard 80mm fans with a better quality rating.

Is there any issue around this? My warranty's are long void.

Current draw could be a problem. And electrical interference could also be an issue.

That said, I would not hesitate to try it.

I've checked the fans i'm going to replace it is, its the same voltage and the same wattage.

Weird thing is the fans originally shipped witha  Cisco router are standard as faras I can tell. They are cheap and nasty bits of kit in my opinion.

This does not work. Do not replace the sans in a 2821 with anything but the Cisco kit. Fans do work but they cannot be monitored via the show env all
