How loud would you say the average Phase Change setup is when in use?

I am interested in going sub zero in my next build but the important question is how loud is it? I don't mind my PC having some noise but I don't want to be in the 60db+ range.

also..out of curiosity..I have access to cheap lab equipment and (while this looks like it might be overkill) am curious whether this type of vacuum pump would work?

and are there limitations to how much you even want to bother depressurizing things? like for instance would it be pointless to get something like what's above because there's nothing that you'd use as a coolant that would actually require pressures that low to boil off?

Can you give us a diagram of how you intend to go about doing this? Or a more detailed explanation at least? I work with cryostats at work so I might be able to help you out. If you want to make something yourself it is going to be big and loud for sure. If you are talking about using one of those premade sub zero units they are essentially a souped up refridgerator and so will contain a compressor, which again is going to be relatively loud.

I am not sure which I would go with. That vacuum pump that I linked was just an example of a possible choice for extreme phase change system. I don't know much about the different coolant choices. It's my understanding that depending on which coolant you choose, you have to match or surpass the vacuum pressure required to make it boil off at room temperature. I feel that I would need a sufficient compressor to go along with any extreme vacuum pump. I'm sure that people have gone to crazy lengths such as using liquid helium/hydrogen for phase change PC cooling..but I doubt I'd be able to reach the kind of pressures required for that on a reasonable budget


nevermind on the liquid hydrogen.. via wikipedia "Silicon-based semiconductors, for example, will freeze out at around -233 °C."

Any type of pump will make a good amount of noise unless it is designed specifically to be quiet. Since this is lab equipment it is definitely going to make a fair amount of noise. What ever happened to the day when people had questions about a product that they know NOBODY they can just find on a forum have ever used actually do their own research and just FRICKIN CALL THE COMPANY AND ASK... sorry for the rant... But dude, just call them and ask how loud it is... Company are always happy to answer questions about their products. have fun making calls to different company, you would be amazed what you can learn.

noise and heat as well.. to create the chilled effect, the condenser has got
to cool super-heated refrigerent from being compressed
