recommended GPH

[the_spankles]

I'm doing a project where I'm super cooling a PC by using an AC unit to cool radiator coolant. I'm going pretty cheap on the pump because I won't be using it for long. What would be a good GPH. basically I'm looking at some that are as high as 300 and some that are down in the 50 range and not sure if it maters.

if you've watched Linus mess with his window unit thats dismantled AF id like you to take note of two things that are going on here

1- he has dismantled the frame, but not the unit.  It 'still' operates like normal, compressible stuff in the loop, on rad get hot, the other gets cold,

2-  Linus has used this a few ways, but they all involve the 'ice-cooler' chest that he has  used to cycle fluid in/out with the cold radiator 'active cooling' the medium,

2a- openish loop, two tubes for one in, one out, both for the system,

2b- maybe it was him, or im mixing up videos i've watched but you can do the same thing, but put the radiator you use in, instead of a open loop, you still get consistent 'loop rotation' and the whole radiator, and any submerged tube gets the chilling action via, dual exchange in a 'vat' in this situation the vat is the chest, and you can use any fluid capable of not freezing (rad fluid)

 

if you plan to use a 'cheap' pump, and by that i basically mean not a D5 or DDC, then it doesn't really matter as long as it has enough head pressure to circulate the system.

for this i would reccomend doing it 2b style, or having tons of fluid to not worry about getting the fluid thats actually cold
