HS40's overheating and shutting down

[ServerJohn]

Has anyone come across any issues of overheating caused by the part number stickers that come attached to the heatsink of the 4way HS40 Blades? When supplied direct from the manufacturer the single processor has this attached on the side away from any airflow so have fited the other 3 without removing said sticker, only the clietn is amintaining this has caused a shutdown due to the processors overheating. Any help or knowledge on this would be greatly appreciated especially any links.
Many thanks in advance.

Are all the blanks, covers, and panels installed? Are the BladeCenter blowers installed and running? Never heard of this failure, but could imagine it happening if the BladeCenter is not fully and completely assembled. They don't come with those huge blowers for nothing!
