Try 2m50 captube, you'll get better temp once loaded (according to pressure drop it involve with that compressor)

Try 2m50 captube, you'll get better temp once loaded (according to pressure drop it involve with that compressor)
few more tests last night before i shorten the cap tube
32m @ 4600mhz with 1.7v on the same chip 6800
Time unit was running 1 .5 hours
Water barrel temp before 16.1c (taken @ the top of the barrel)
Water barrel at the end 19.5c (taken @ the top of the barrel)
Barrel size 120l
Ambient in shed 15c
Ambient outside shed 12c
the tests were run around 8pm in the evening so the ambient temps had dropped quicker the the water temps
as you can see the unit is running under load in a vacuum
this however is where the best loaded temps were to be had -47
when i increased the charge so the unit was running @ 0 vacuum the temp went up by 4c so -43 under the same load
the high pressure stayed @ 13 bar

loaded hx temps 32m@4600mhz/1.7v
HX temps peaked at T1 36c measured at the start of the hx and T2 21c as the water left the hx
at the start of the run as image

The water going into the hx is hotter than the water coming out of it? After it condensed the vapour refrigerant? That doesnt make sense. Unless I am missing something.
Great work mate, -47 @ 4.6gig with 1.7v going though that chip, wish i new just how many watts that converts to, do any of you guys have any idea of how many watts this chip is putting out at this speed and load?
Again good job Baz.:clap:
Why should a Plate HX improve performance?
Do you think the refrigerant will be much colder than 21c with a plate hx? The condensor is good enough! What temp. has your water? (around 18°C i think so he is very close to the max.)
I'm thinking when Baz takes it off his water butt and goes to a WC setup like most of us will have about the place and there being more surface area there and to also experiment all in the name of fun and finding out
like moc has said pete the coil hx has work ok so far
the water cooling experiment has work in that it reduced the high side
pressures in the unit at this load by quit a bit
which means to me that i can put in a colder refrigerant now
i think this is where the real gains will come from
What ya thinking gas wise now then? I love it how you never stop pushing the extreams and limts
Tom your correct dude. SuperPI is Single Thread only.
unit is ready for sacha35 to work some magic with the water cooling

Nice work my friend :up:
Regards
Very clean, I like it. I hope it turns out to be efficient.
Nice Bazx but erm...has sacha35 gotta fit a suction line etc etc?
I cant help but notice that you are using 90 degree elbows on the water inlets to the dsh/hx. Anybody who has seriously water cooled knows that this is a :shakes: in a loop. It takes away from the efficiency of the loop and thus some performance. I believe that you should switch up the vapor and water inlet locations so the water can flow straight though.
