The polycold spec's

[charlie]

Ok, ran my chilly1 mod Polycold autocascade today and yeah... it works :D

Boy does it! I was thinking it would have GPU-level capacity... but I threw it on a Venice 3500+ anyway...
So I fire it up and it takesa bout 5 minutes to start moving, hits about 10C and falls to -40C real fast. Then slows down... so it's at -50C and I'm like COOL! I'm at 1.5v and 3100mHz... so I start a superPi... and to my surprise, the temp KEEPS falling. UNDER LOAD! At 1.5v it hits about -62C... loaded it "might" drop to-61c.
So later on I'm totally flogging it at 1.75v and 3300mHz running 3D, lol... and it's idling at -58C and loads up at about -55c The "worst" temp I saw all day was -53c.
Sounds like pretty good capacity, eh? Is that about like a 507 Mach2 or a bit stronger? Better than a big single stage??

considering single stages do about -35c to -45c evap temps under load ur 10 to 15 degrees ahead of em

that thing is amazing btw :slobber:

Very Cool Charlie :woot: Wish I had one too. :clap: Nice temps.. :D

[gkiing]

damn, thats a big mofo of an autocascade! Must need lots of room for the phase seps and extras not found on single stages.

[masterofpuppets]

Those Polycold units are INSANE!

[(sin)morpheus]

Wow, looks awesome! I've never heard of polycold though.

[charlie]

The workshop was little bit "cooler" this AM, unloaded, no load it hit -65C, hehehe....
On Dothan I'm hoping for -60C load.

[haPpydUde]

[Cpt Twitchy]
