Hi friends,
My 6610 started spinning up to fan speed 2. It would spin up for 10-30 seconds and slow back down to speed 1 for awhile. Rinse / repeat. It did this for a couple days and I finally got tired of it, so I took off the lid. It had been running for over 300 days in a garage rack, so some amount of dust had built up on the faceplate, but it wasn't blocked or anything terrible.
I opened the lid and found this:

Yeah, the spring loaded heatsink retention pin had broken due to age/heat/thermal stress. Luckily the metal spring landed on top of the heatsink and didn't short anything. And yes, it had been running like this for multiple days.
I couldn't get the remnants of the push pin out of the MB hole. So in a bind for time, I scientifically cut a piece of foam to squish between the top of the heatsink and the case lid, to push the heatsink back down. It's now been running like this for multiple days, staying at fan speed 1. Done.
Thanks again to fohdeesha for enabling such a great switch to be the backbone of my (and now several friends) home network.
Cheers
