dipping arctic ceramic in ln2....
 

i tried it last night.....

and i think i need to try it again :D

and prolly dip my polymer capacitors too...

I don't get it, any pics, video's, point, results? Or are you just in a spamma lamma mood?:Dizzy:

its just testing ceramique and how it becomes when its dipped in liquid nitrogen....

i'll post pics later...

i also thought whats going onbut didnt post anything lol

i wanna try ln2 but dont got a pot or container thing

yesterdays pics

Containers can be rented usually.

Are you on a benching team? I am sure one of your teammates has a cheapy pot they could lend you.

IF not hit up the forums at places like OCN/TPU and 2CPU. They have open marketplaces, and tend to pay a little more but still less than retail.

If not ask otternase duniek or umm... damn cant think of the other polish guy Over at XS to build you a cheapy. When you have the money you can grab a K|ngp|n pot FTMFW!

whats the ln2 do to the ceramique? I dont get it

lol, me either :Dizzy:

Freezes it, i imagine.

Actually i don't see how it possibly couldn't, i froze ceramique during my last dry ice session :D

I suspect Honda just has a curious mind.

I have 3 kids and periodically find things in the bottom of one of my dewars that I did not put there......

Once i have fundage for LN2 (it's expensive here :() i'll be freezing everything, i'm sure.
It looks entirely too fun to freeze things :D

sigh*

yep you haz that right

thanks you got that right.:thumbsup:...been an engineer for many years now :D

"if its not broken, take it apart and fix it"






vimeo is giving me a hard time...i haz the video...2 videos..

finding: ceramique is good for dice.....

for ln2.... once it reached liquid nitrogen temps it was hard...but once it was removed..it was semi liquid in less than say 20second...

so heat it up and crank it down like the guides tell you?

The Idea of thermal paste is not create a joint between the two subjects, but create a material to bond the holes in each. Less is more.

I have 2 tubes of ceramique I purchased like 2 years ago... cuz my AS5 was getting low. MY AS5 still aint dead. It was the big 3 ounce container and we are talking at least hundreds of remounts between the tubes. (between all 3 tubes)

i'm benching @ 2.1v on my 32nm cpu.... i'd rather use something else.

anything that is under -190c or so expands...

also its specifications

Temperature limits:

Peak: –150°C to >180°C Long-Term: –150°C to 125°C

Agreed, less is def. more.... I have been spreading a bunch on, clamping down to thin it out. The extra comes out the sides. :ohcrap: I'm a spreader though, and that shit is like silly putty. :laughing:

anyone else have this happen. Im benching around -140c for a while (CBB temp) and then I pull it all the way down to a full pot and when its flying down in temps there is a giant pop from the bottom of the pot and I get a BSOD. Restart and its fine, so im wondering wtf it is. It only happens once per session but it happens every session without fail, ASC related? I do the usual heat up to 70c's and twist the mount to get an even spread and its always a perfect mount but wtf is the popping?

I'm not sure there's a thermal paste that doesn't freeze at ln2 temps, ln2's kinda cold :D


I've been having excellent luck plopping a bunch on, squishing the pot on top, clamping it down, and then running the cpu at normal to slightly elevated volts and light load till it's at 60-70*c, then starting with the cold stuff.
The patterns when i remove the pot look great.

That is, of course, dice.



EDIT:
Thermal expansion and contraction of the cpu would be my guess, and the movement breaks contact with the pins ever so briefly.

I never had that happen. I get some popping when pouring way down sometimes but never a BSOD?

I think it's the copper contracting. I noticed that sound too at ~-100c and then again at -120c and -140c+. As for the restart, who knows??

anyone try NOT using a TIM?

Im thinking this as well. Pins definetly loosing contact or something when it pops, its only once though and it settles. Weird huh

Nope, i know that toothpaste works decently for ln2 though :D

I was wondering how vaseline or di-el grease would perform under the pot, but figured it would prove too messy to try. :ohcrap:

I heard the popping too, scared the bejesus out of me the first time, but no bsod's or any other bad things. Had pictures of the rig blowing that first time though :scared:

I hate ceramique cause its such a goey mess, but seems to work best on frozen parts. Less is more, but too little is less :P

part 2 maybe later...

Says the video is private, man.. :Hi:

That's what i was using back in the 486 days, when the concept of official thermal glop hadn't been thought of yet.

Worked great back then, it'd probably work pretty well now.

Downside: Silicone grease is almost impossible to remove completely.

486? That a new Fermie revision or something? (j/k)

As far as I'm concerned, nothing really comes all the way off the ihs anyway. It may look clean, but take a good picture of it and then marvell at how dirty it looks... :blush:

What's the freezing point supposed to be on that stuff anyway? might be on to something there....

tried it...not really good on one mount...the cpu ihs is curved..the pot is flat..contact surface are prolly less than 60%....i'm just guessing but i can retry...but i already have my good tim..so it will be awhile when i try no tim mounts ..
those r insulators...worth a try though

on dic this is not happening

on ln2 it does....worth studying :D
hmmm ill check in abit

privacy off

check video

www.vimeo.com/hondacity :D

I wanna stick things in ln2...

lol, here, kitty-kitty.. :blink:

Voodoo mobo mojo.

mine starts popping around -70 there is several pops then its done. I figured it was the last of the heat getting pushed out of the area. Anything pops when you cool it or heat it. Cookie sheets in ovens, siding on houses, gutters ect it. Metal shrinks when cool an expands when heated up.
If I hang an 80 foot gutter in winter temps the first 70-80 degree day will pop an kink that gutter unless I put an expansion joint in it.
I think its normal. As for the Bsod idk maybe the pop creates a vibration ripple an crashes the cpu.

I used to get the pop on quick temp pull downs but I haven't pulled down quick in a while so no pops lately.

CPU usually freezes or bsods during quick temp movements. I believe is has something to do with how the cpu is hardmodding, like a thermal detection failure switch that says that something must be wrong cuz temps are moving too fast in the wrong direction. But then again, I stayed at a Holiday Inn so wtf?

That makes sense. It'd probably trigger the sensor that is supposed to detect the heatsink falling off at full load.

CPU goes ZOMG EJECT EJECT EJECT!
