C200 M2 fan speeds

[jamesleonard]

Hi there,

I'm having random issues where the tach fans ramp up to 15k RPM for no reason, and they don't spin back down to normal speeds.

I had the server powered off last night and when I powered it on they ramped straight up to 15k

I'm running the 1.4.3(u) firmware, any ideas?

James,

We had a couple of similar cases in the past, typically related to some internals (like PECI or i2c) communication problems.

If you have not given it a try... re-seat the power supplies.

Or better yet if you don't mind a bit of troubleshooting, open a TAC case. All the bugs I'm aware of have been fixed by U-release or unreproducible.

Hi Marcin,

Sorry for the late reply.

I tried reseating the power supplies, including swapping them round to no avail as the problem randomly persists

I don't think its possible for me to open a TAC case as the server is out of warranty and its a personal server I purchased second hand
