For your use, this is absolutely the definition of more money than sense. The gains you get for the activities are an asinine expense to mortals. That said, we're here to help!!!Yes I am willing to spend a few thousand on a microdosing machine,
No. They are as different as Apple pie and Shepard's pie, lol. The commonality between them is they cool sub ambiently. Otherwise, they are two different things. One uses LN2 to make it REALLY cold, the other uses phase change (and electricity) to do the same thing. Totally googleable things (phase change cooling and LN2 cooling) to see additional differences.I thought the phase change cooler did that for me but apparently from what you are stating I need that unit as well as a microdose unit ?
LN2, manually poured and through a machine, is A LOT colder than a single stage. If you look at the specs of the one Johan linked, it says it can keep -30C at the head (which doesn't mean your CPU will be that low) against a 320W load. LN2 is almost -196C. Depending on the pot used, the amount of LN2, CPU used, and load against it depends on the temps you'll actually see. Some of the really power-hungry chips will often go positive degrees during short intense runs, for example.
You probably will use less in a microdosing situation. But let's say it lasts a week (I don't think it will with a few several-hour sessions /week)... that's (at least) an extra $250 a month for what amounts to very little on the performance front.
EDIT: See all of these threads.......
They are in the same section as yours, but above it. They answer about 75% of your questions so far. Take a look them. Twice. Maybe three times, and see what you come up with after.
