LittleDevil's CPU Pots (LD CPU-R1)

[Deanzo]

Hey LD

Been DI benching with your pot today and I must say Im very happy with it.



My 82K in 3D01 (non sli) is my favourite run of the day, but Im all so happy with my 1M as well



Any how my friend its a great pot.

Nice runs with a nice pot.

[LittleDevil]

Really nice results my friend!

Hey LD,
nice work =)
Could you send me a PM with the prices of all versions (so alu, alu+copper and only copper) of your pots?

Best Regards
Dennis

nice shiny pot
but due the cone and possible internal steppers, you lose mass around the core at the height it should be for sick load holding.


i like the engraving though

[LittleDevil]

Belive me that it works very well on load

I'm curious how does thermal stress affect the rubber sealing ring after some 10 or more liquid nitrogen runs? My bet says it will disintegrate due to thermal stressing no matter how high quality rings you use.

@Deanzo: 82k is on a 8800 Ultra with such clocks is a fairly poor run :/ -> 80k on 8800GTS and lower clocks -http://service.futuremark.com/compare?2k1=9239093

@tiborrr: there is no problem for rubber sealing ring... it works perfect i know one guy who run LN2 more than 10x on than pot and oring is like a new.

Those orings are custom made, resistant to acetone and resistant to cold. And you know that there is no direct contact between LN2 and oring.

[tiborrr]

Indeed, but the tube serves as a heat (Q) accumulator so the rubber ring still exposed up to -160 ~ -170˚C. Exposure to accumulator is imho doing more damage to the ring than exposing it to a LN2 since LN2 has real low cv value and is a bad heat conductor.

Care to say where did you get that O-ring? Interested in it if it really hold such low temperatures

[LittleDevil]

Look tiborrr there is NO problem with oring on low temps.... Make your own thread and discuss about damage...etc on LN2.

Kind Regards

if you won't mind telling me LD, how do you thread the Male portion of something? like on the copper part of the pot, is there a way to thread it without a super expensive pipe threader or a cnc lathe?
thanks and sorry for ot

[LittleDevil]

More toys for playing

I dont know of anyone has brought this up, but since copper and aluminum have different rates of cooling/heating, the metals will contract at different rates, possibly causing a LN2 leak or causing the aluminum shaft to get stuck to the copper base.

[Bigchrome]

Ln2 leak is pretty much not going to happen, and while the shaft could possibly get stuck to the base it will be fine when it thaws out.

Thanks for the kind words
Are you psychic or did you use a crystal ball to work out the clocks for the 3D01 run as they are not posted. in fact the run you posted has higher card clocks than I was using.
And apart from that, it was the first time I had used anything other than air to cool my cpu, so personally I'm very happy with the results.

As for the discussion on the O rings, I'm very new to this kind of thing so I'll only give you my ovservation, after about half a dozen dry ice run's and five different cpu's under LN2, as far as I can tell the O ring seems the same as the day I received it.

Nice LD, I like to see several units all lined up. 7 more frozen processors for our viewing pleasure

[LittleDevil]

Another one engraved.





Kind Regards

Silver plated copper part:

[Solarfall]

uuuuh silver plated version.. nice almost better than :banana::banana::banana::banana:

[koda]

This is what i found in my PO box yesterday













Congratulations LittleDevil !

Bench's results as soon as possible
