I worked in several banks using IBM mainframes. The server room was always like a freezer.
I think for now, many companies are perfectly ok with air cooling solutions. Besides, it's much safer to have air-conditioning and fans than some liquid flowing. The simpler the system, the less accidents occur within it...
And believe me when I say that, if a company owns an IBM mainframe, they pay big bucks and they *don't* want any accidents.
