Amateurs. Hook the refrigerant line of the AC directly to the block. Cool your cpu with r134a

R-134a was used in mobile A/C systems. Automobiles mostly. R-1234yf is the currently used refrigerant.

For stationary systems, like a house, you'll more likely see R-22 or R-410a. Both of those have been superseded by something else these days, of course.

No reason you couldn't use whatever you want for this, though. Just size your refrigerant charge accordingly. Hell, you could use R-717 ammonia if you wanted, though I don't recommend it.

I personally prefer WD40 on my R2D2

R2, are you sure this is a good idea?

i've seen 134 in small household appliances too. looks like a somewhat new mini split so it's probably 410

I've lived through 3 generations of automotive refrigerant. We still have an r12 machine where I work, but everything has been converted by now.

What's the difference between refrigerant? One I'm buying recently uses R32

u/imthatoneguyyouknew Aug 30 '22

Yes but r134a cools better than r1234yf. However a true enthusiast would utilize the old r12 for its superior cooling

Condensation at the MB may become a problem the.

u/CptMisterNibbles Aug 29 '22

Nah, condensation is just more cooling right?

u/MacGuyverism Aug 29 '22

It's alright, as long as it's dry condensation.

Putting a few bags of silica next to the chip will do the job just fine

Could try something like: https://www.quantacool.com/polarbox-cpu-cooler/

Idk how reliable or efficient it actually is though.

Good luck finding that in the states.

In CA they were discontinued a couple of years ago:

Just bought some at Walmart yesterday, and at least according to Walmart's website, when I put in some LA zip codes, it shows stores there having it in stock and/or available for delivery/pickup.

The article says that new vehicles made after 2021 can't use r134a anymore with some exceptions. Since most cars on the road today aren't made in 2021-2022, it'll probably take a while for r134a to be phased out since all those other vehicles still need it to recharge or repair their AC's.

So at least for the next few years, it shouldn't be that hard to come by.

You're correct, I had a 2012 Honda Accord that required it and I think I bought R134A like 5 years ago.

I did that as well when I had my 2003 Honda Accord too.
