Kayl evap enclosure masacred + cbuzz phaser

[eva2000]

Oh it ain't that bad really

As some folks know LGA775 motherboard's have some caps near the cpu socket. These caps block and restrict, Kayl's evap white enclosure from fully sitting down and allowing evap to contact the cpu's IHS.

I put off modding the white evap enclosure as i didn't have a Vice to clamp the enclosure down with and well couldn't find where i put my Dremel :heh:

Today, I just felt like hacking up the white evap enclosure, so found my small hand held hacksaw and decided to just hold the evap enclosure in my left hand and holding hacksaw in my right hand, began hacking away at the white plastic enclosure (yes could be a disaster waiting to happen if i slip ).

Luckily, the mod was done without any blood shed or lost fingers

After: Full pics http://i4memory.com/phasechange/kayl/lga775_evapmod/





I used some cut up strips of thin sticky back closed cell foam that Kayl included with the unit and padded up the exposed foam area somewhat. But left the bottom edge open so to clear the caps on LGA775 motherboards

Shame to have to hack up the beautiful enclosure but it had to be done

decided to mount the modded Kayl evap on 3.46Ghz XE cpu with Abit AW8D just for a test run since i never used phase on LGA775 before....

3.46Ghz XE cpu on water did 4.8ghz

Bios can't show negative temps so right now memtesting to get an idea of what the 3.46Ghz XE cpu can do on Kayl Black Frozen SS http://i4memory.com/phasechange/kayl/arrived/1/html/

@stock 3.46Ghz at 1.2875v evap temp was -39.2C
@ 4.6ghz at 1.4375v evap temp was -35.2C
@ 5.0ghz at 1.5625v evap temp was -32.2C
@ 5.2ghz at 1.5625v evap temp was -30.9C
@ 5.4ghz at 1.5625v evap temp was -30.2C

will freeze my E6600s later

[eva2000]

Yup more phase change goodies. I bought cbuzz's 1/6HP phaser unit with plans to use it with interchangeable mounting for cpus via the cbuzz Mega mount and to mount on MCH/northbridges

Haven't got around to testing it stand alone yet but will soon

Well fired her up into windows with 3.46Ghz 955XE and Abit AW8D 11 bios and 2x512MB OCZ PC5400 Platinum XTC 3-3-3-8.

Max validation so far 3.46Ghz 955XE @5682Mhz at 1.6875v (uGuru windows set) = 1.63v idle in windows and 1.58-1.59v under load.

Evap idle = -32C
Evap load = -29C
Room temp = 26.8C



Max 1M & 2M @5618Mhz same vcore as max validation.




Super Pi times are slow heh - no tweaks just ran to test max cpu clocks. Core 2 Duo has come along way for sure!

[kayl]

whats the WR validation for that CPu eva2000?
that as to be close hey
good job on the enclosure mod as well.
Gonna have to use cbuzzs cooler on the chipset next and run conroe

[eva2000]

not sure i think Pentium D cpus have >6-7ghz by now i think hehe

955XE is good for stress testing the phase change units though ... i think 955XE at 5682mhz at 1.6875v is like ~380-400W on cpu itself ???

5682Mhz at 1.6875v is 360W

[eva2000]

ah yuh ~360W heh

[eva2000]

Now i know why some many phase change or sub zero temp users have killed their LGA775 boards! Motherboard and cpu are fine, but curious to see if any condensation formed after i switched off the unit and left it to warm up overnight.

I took the mount of my AW8D motherboard and man was the LGA775 cpu socket damp and wet, the back of the cpu grids and stuff were wet too. The surrounding cpu socket area was dry though.

Folks have said the LGA775 socket is hard to get an air tight seal and guess they're right. I think the only way to safe guard against this would be to use dielectric grease in the cpu socket area. Or if you don't like the idea of messy dielectric grease all over the cpu socket and cpu itself, after each benching session ends leave it overnight and in morning unmount the evap and dry it all out for another run ?

[dinos22]

well if you're going to do it right grease is really the best way.............................didn't you use grease?!?

[eva2000]

nah no grease.. AW8D is a dummy test board so to figure out issues such as these before testing on P5W DH

[kayl]

i wouldn’t dare not use grease in the socket 775 systems eva2000. That metal tab gets real cold and any small amount of air turns to frost. Last thing we want is moisture on cpus, cpu will corrode in time for sure. Also important to make sure ya fill the gaps with enclosed foam as well
I did a run for a few hours with insulation just like this and the metal tab had white frost all over it. As enclosure wasn’t sealed to mobo insulation When ya turn the system off that melts and drips onto the mobo.






When I insulate like this have no issues. That sticky back tape I sent you can also be used as well. now enclosure is sealed to mobo insulation. I only use grease in the socket and yet to kill my mobo. No other precautions take to protect system either.




i cant wait to see the P5W DH and the E6700 and E6600's eva2000.

[eva2000]

now i'm confused with 1st sentence than 2nd last sentence ??

for LGA775 dielelectric grease in cpu socket or not ?

or do you mean do not grease LGA775 pins but only the inner square set of SMTs etc ?

Yeah been playing with the sticky back foam both cbuzz and you included with your units and seems covering the entire metal retention mechanism is doable

Yeah hopefully all fun with E6700/E6600 and no unfortunate accidents hehe

[exhausted mule]

5682Mhz at 1.6875v is 360W

how do you figure that out anyways?

[eva2000]

((1.6875/1.2875)^2 * (5682/3460)) * ~130w

[jinu117]

Ehehe... 360w... Anyways, as what some of us have suspected you have SS unit tuned for very heavy load Eva2000 Going to help you on conroe when you start pushing 1.7v on it for sure (yes people, conroe at that voltage is even more monsterous than most people have expected).
What I always recommend is use sealstring on LGA775 or corktape. Not the easiest to clean off but due to flexible nature of it, you can actually squeeze it down on tight spots till it closes all gaps Give it a shot

[dinos22]

eva i'd be covering the whole thing for sure

one thing that is ty with that grease is that no solution can clean the ..........i spent $50 on freaking sprays and and nothing cleans the damn thing

put it in both to be safe, its a pain to clean out though.

this is a good link to work out processor wattage when overclocked

Did you know if you go to the chemist they can sell ya behind the counter industrial strength acetone eheheh. Ya cant but it anymore other wise. And these days they don’t have it in nail polish, if they do its only a small percent.
I had to RAM my new mobo, the cd rom was working, then stopped the day after.




jinu117 id say that Eva2000 current cpu under phase is hotter than the conroes.
I had a E6400 at 1.7v bios and 4ghz and was quiet cold compared to my 920D.
Not sure if the new mobo undervolts more than the old mobo though

[eva2000]

yeah seems covering the whole thing is needed.. just ripped off the insulation for AW8D and even under the insulation it was wet and damp heh.. might need a light coat of red LET too hehe

well starting the insulation process and plan to do the following:

1. 2-3 coats of Electrolube CPL - Clear Protective Lacquer on back and front side of P5W DH - sockets, pci-e/pci and dimm slots taped up - touch dry in 15-20 mins and recommended 24hrs overnight
2. 1-2 coats of clear nail polish on back and front
3. 1-2 coats of red Liquid Eletrical Tape (LET) on back side and front side
4. Going to cover back side of motherboard with a layer sticky back closed cell foam.
5. Front side closed cell foam piece, with the LGA775 metal retention lever and frame covered in stick back closed cell foam as well
6. A dab of dielectric grease on back of cpu caps etc as well as a light coating inside the square cpu socket SMT area.

[afireinside]

Yeah insulating LGA is a nightmare. I didn't want to use grease but it's the only way. I put a thick coating of nailpolish on the back of the board and around the socket, on and under all caps as well. Load of grease in the socket then a foam gasket with more grease on caps. It's a HUGE mess and possibly overkill for a 4-5 hour run @ -70C but with mobo prices these days I don't want to take any chances.









The way gautam made it sound, I figured the entire board would frost over. The cold didn't spread past my foam though. The thing I was concerned about most was water on the caps and inductors right next to the socket. Get those wet and it probably won't end well. Hence the load of vaseline on them.

Good luck eva! I look forward to seeing your results with conroe on that cooler

[Patriote]

OMG! afireinside Thats getting really REALLY WICKED SICK MAN!

[LukeXE]

INSANE

As I was at overclocking party in poland with my autocascade, with full insulation on Asus P5WDH mobo after 6-7hours of benching everything was wet :| We couldn`t use any grasses or something that could make motherboard to look like not new mobo, dirty, because it was just borrowed stuff.

so with only armaflex and -65*c on evap after few hours everything was wet, around socket, at the back of motherboard etc

[eva2000]

afireinside is that bubble wrap on that board ? heh

I've only gotten as far as a dry test mount for tonight. I spent all the time doing up my insulation around cpu socket and then I realised i forgot to install the 4x mounting threads for the evap through the motherboard LOL

Had to remove all the insulation and mount the threads and then put the insulation back on hehe.

As you can see from pics here http://i4memory.com/phasechange/kayl...on/p5wdh/html/, I still need to reinstall the Radiical chipset waterblock on MCH/NB etc so more to do for tomorrow

Performix Red LET


First top layer of insulation & dielectric grease in cpu socket only


Second top layer of insulation using thin sticky back foam (Aerotape) - whoops forgot to mount the threads to the board


Removed insulation, mounted threads and reinstalled insulation


First dry test mount - see gaps in middle pic below what should i fill it in with or do i need to ?

[andL64]

not necessary....


i ran this dry ice pot a few hours no problem and little later with air again.... everything gonna be alright

[~PI-IOENIX~]

why difficult if it can be that simple andl ;D

First, eva is running phase. I'm going to assume he DOESN'T want to have to shut down and remove the evap every 4 hours so that the board doesn't die. Also you're using a chilly1(?) tube, that's tiny. I was dealing with a 3" wide 7lb copper monster. Much easier to freeze things over.
