That sounds like a good idea, I think I will try itIf its sled 2 (the sled underneath the other sled that has a system in it, I had the same problem. It was shutting down because the controller chip was over heating. I attached a 40x40x10mm fan to the heatsink, and it kept the temps 20' lower on the chipset, and it made all the difference.
Would love to know. Last year, I bought a C6100 2-node unit with pic16 FCB. gave up on it and it has been shut down.Just in case anybody is still using/buying this older hardware, I just tackled reviving my server and making it STUPID QUIET with no heat problems!!!
Catch is, you need to remove the 3rd top sled, it can only run as 2 nodes for this to really work.
I'll post pics in the next day or two to show you what I did, if anybody is interested.
