The guy who made it is a friend of mine which made this as a hobby. Most of them are bought from his pocket, some are borrowed from friends and others are samples send by manufacturers.
You have all flavors of testing from fanless to extreme air conditions. Testbed is the same for all of them. We are on SPCR but unfortunately no sound measurements but at least you have fanless and low RPM tests.
IMHO this is the most complete and comprehensive super-coolers roundup ATM.
Enjoy.
