Ideal diametre for a cilly1 or steper evap???

[quintus]

Hey,

Thinking of a new batch of evaps for myself. The old ones are good but not for quads and super overclocked e8600 at 5,5 with 1,8volts in it:D . I'm sick of big delta between cpu and evap temperature.

So what diameter will be advisable? 5cm, 2inchs?

Please take in consideration this type of boards with caps very close to the socket.

Maybe some new design ispired by the pots where the diameter of the base is not the same with the diameter of the pot...

Thx,
q

Something like this right?

You really don't need a monster evap.. the Cryostar proved this using principles established by Eleven. You could build an evap with roughly the same diameter as a Chilly1 evap and achieve monstrous amounts of surface area. Even the cheap Chilly1 evap is still a useful evap, I've been using them for years and they have worked from A64s to B3 65nm quads to 45nm quads.

I dont have acces to a machine to make an eleven like evap, only steper:)

jiu said: Cryostar evap while can handle up to 250w, is not really suitable evap beyond that point to be honest from what my test shows as well.

Mine i guess is a bit lower than this watage but then again: 250 is not enought! i got a 35mm diameter with 40mm hight.

Keep in mind:
The goal is to cool the CPU core, not the CPU hold-down/mount thing.

CPU core is maybe the size of your fingernail. Not even.

With a huge evap like that i imagine it would be really annoying to insulate, and you would just be thinning out your heat capacity if that makes sense.... (so do (load tuned for)/(pi x r^2)<--dia of evap and you get watts/mm^2..... increasing dia of evap thus gets you less watts heat capacity per mm^2 )

Do you understand what Im trying to say?
fyi: 45nm cpu core is about 15mm x 15mm small.

copper is cheap, i picked up some 3" and some 2.25" copper. I would say 2" copper would be a luxury :up:

cheers

@sjg0: with a 2'' evap u got enought place to insulate, going from 1 size of evap to another doesnt matter! you still have to do it :D, and verry well offcourse

@sdumper: yesss!

Oh yeah verrrrrrrry cheap:p: cmon man 2 years ago the price was half of what is now, and also going for bigger diameter costs more for the cooper and work force for making of the evap & time...

Yeap 2'' i was thinking too, seems like the perfect size:)

Quintus, if you find a source please share because Im getting ready to start a new build next week and really want a larger evap than what I was planning on using.

i paid about $8 an inch for 3" diameter copper and about $4 an inch for 2.25" copper, for the 2.25" copper thats about $6 per cascade evap (see my cascade thread for the evap im talking about). the copper cap im using might have cost more then this.

cheers

Teyber how long until you can start cutting copper evaps again?

Im using one of your existing steppers for an i7 build im starting next week but if timing is right I would really like a larger evap.

not sure... i don't want to rush the conversion :shrug: not for a couple weeks for sure.

btw the larger evaps, since you have to remove SO much more material, at least manually took me about 5-7 hours therefore are really expensive :rolleyes:

Teyber, maybe we could work out a trade say an evap for a copeland :)

yeap ill hop you a pm when the cnc mill is up :)

@sdumper: Sorry mate, i live on the other side of the globe:), teyber is your man;)

@teyber: That's 3times less of the price that i have to pay for cooper here in Europe!

LE: Make it 1/4;)
