Further to this question about Blade vs Rack servers I wanted to check some stories I have heard.
Are Blade servers much noisier than regular rack servers? (or was that just when they first came out?)
also, how much more cooling equipment do they need?
NB: I'm probably talking about 1 chassis with 7 or 8 blades in it, compared to 7 or 8 normal rack servers. Not huge numbers of servers.

I would say anecdotally yes. They are more noisy. Although often more efficient in terms of overall power consumption, the act of pulling and pushing air through passive modular components with large front and rear facing blowers is always likely to create more noise.
Blades shouldn't need any external cooling equipment. Just a hot and cold aisle to deploy in ideally. The chassis takes care of the rest.
