How loud is a phase change unit?

post #1 of 6
Thread Starter 
Does it sound like a portable fridge (the hum noise) except in more a constant fashion? Or is there no noise at all?

The are acctually very quiet!

My Mach I is almost silent when i switch it's fan's off

It's a kind of really low pitched hum, i'd say it was around 25dBa but it vary's for different unit's.

The 25dBa rating is when the fan's are switched off but i'd say it's about 35dBa when the fan's are on

Hm not bad. It's better than an XP-Anything with a giant fan on it ^_^

Do you need the fans to be running?

When there is a load on the proc, yes. But when it is idling, the Radiator does well enough passively.
