what is the best heat paste to use with phase?

using arctic cooling mx-1 atm. with an evaporator temperature reported at -55, i get a cpu temp reported at -25(all at idle). I have checked and remounted the head with no change. is the thermal paste freezing and causing a problem?

[Omastar]

How about Arctic Ceramique?

How about Arctic Ceramique?


That's the best for cold temps as I've heard......

[LostInSpace278]

Yes, I think it is rated for -150°C. I use it on all of my stuff !!

[harvshark]

I also noted that the specs on Ceramique indicate that it is totally nonconductive and noncapacitive. So there is less chance of it creating any problems if it gets where it don't belong (that never happens, does it?).

Generally speaking AS Ceramique is the best paste to use with phase cooling.

However in your case there may be no problem at all.

You say 'reported' evap temp. What system are you running? Mach2, Vapo, or custom cooler?

There is always a variance between the evap and the cpu temp at both idle and load, and while your difference seems higher it also depends on the cpu, the paste, and the system you're running as to whether you're seeing correct readings.

A little more info might help to be sure as to whether there is actually any problem at all.

What about using Coollaboratory Liquid Pro with Phase?

I`ll say "No" ! :P

[hipro5]

Here are some older examples of some of them on a single stage.....
Temps reporting was from mobo's sensor.....
Take a look at the days as they pass....

Propably Arctic Silver got under some kind or "corrotion" - it's materiels - after some days....

As we see.......Arctic Ceramique for the WIN.....:D

[Brettbeck]

Maybe it just takes the ceramique a few days to set in or something. But it looks like once it has it's the best one to go with :D. That stuff is quite expensive though :( .

[LukeXE]

AC is expensive ? no way ! 5euro for bigggg 20g tube in poland !

[Brettbeck]

lol that's cheap Luke :D. Here even on eBay it's about £10.50 Inc P+P for 22g tube (http://cgi.ebay.co.uk/ARCTIC-SILVER-CERAMIQUE-22g-THERMAL-COMPOUND-PASTE_W0QQitemZ150099764018QQihZ005QQcategoryZ4632 2QQssPageNameZWDVWQQrdZ1QQcmdZViewItem) :( , what a rip off lol.

I just got a 22g tube for $8.

its a custom single stage unit. danfoss11nf compressor, chilly1 condensor, desuperheater and additional cap tube, R402a etc etc etc.

I sent the unit to a refrigerant dude to tune it for me, as i dont have the licence to handle refrigerants to do it myself. He also was supposed to have calibrated the temp probe on the froster. The thing im worried about is if he has infact screwed me over, and just set the temp to something more impressive and the cpu temp is reading accurate.

Its being used on an asus a8n32sli and fx60. I have experienced in the past some crazy temp readings reported by this board, and the forums on asus.com are littered with people asking about crazy temps could be the problem?

When heat paste freezes does it becomes an insulator?

I really think its the evaporator mount, but i reset it a few times now but with no difference. what is a socket 939 mount usually like?

The main reason i worry is cos under max load the cpu reports at -9 and core at -14 (argh!), with the cpu at 3.1ghz per core with 1.55v, which is 197watts of load or thereabouts right?

the unit with the dummy load on it was supposed to be tuned to hold -35 at 185.

The evaporator temp after 30mins of dual instance prime with 1024k FFT length at the above speeds is -48. this is much lower than what it should be for those loads isn't it?

i hope thats more info, if u need anything else just ask, thankyou very very much :)

[LukeXE]

Is the bottom of the evap flat ? It sounds like not good contact between the cpu-->evap.

That mx-1 thermal paste is a little bit "shi*tty" for phase ;) try with arctic ceramique, I`m sure that results will be much better.

'The evaporator temp after 30mins of dual instance prime with 1024k FFT length at the above speeds is -48. this is much lower than what it should be for those loads isn't it?'

That's quite tough to say for sure, but in my experience an FX-60 at that speed and vcore isn't actually producing huge amounts of heatload.

Beyond that, the temp difference from the evap to the cpu core can be anywhere from 25 to 35c.

You are getting -48 evap (if reasonably accurate) and a core temp of -9 to -14, then that's a difference of 35 to 40c.

Taking into account both the paste you are using (thanks to Hipro for illustrating that so well :toast: ) and the fact that a motherboard can be pretty inaccurate at times, you're not as far off as you might think.

So, the advice to use Ceramique is well given, it's been the best performer for phase and used for a very good reason. It works.

If you switch to ceramique, and you don't see at least a slightly smaller difference between the evap and core temp reported it could be worth looking at the evap's flatness, the IHS's flatness, and the clearance of the mount itself. If the base has a really nice flat thin imprint on it, you're probably ok and you should just consider using ceramique in future.

Hope that helps, but if you have serious doubts about the performance of the Unit or it's ability to hold load, find another builder and ask if you could get them to load test the unit to check it, if they have accurate testing equipment.

Arctic Cooling MX performs better then Arctic Ceramique and is rated down to -50C, might want to give it a try.

Anyone tried using the Shin Etsu stuff subzero?

[n00b 0f l337]

Its yellow in those graphs.

[Gautam]

There's a lot of variants of it...pretty ambigious. I'm completely unfamiliar with them, but even looking at that review there are at least 3 which perform quite differently from one another.

[n00b 0f l337]

Oh, my bad.

[Gautam]

Nah, I was super ambigious...I still don't know how Shin Etsu's model scheme works. I'm hoping someone else does and happens to have gone well below subzero with it. :p:

[Blaster]

the temps you reported are quite normal for amd system

difference is ussually around 20ºC when cpu idle and 35 to 40ºC when on load

different mboards and cpus will report different temps

[DEVIL K-ce]

Arctic Cooling MX-1 not good for me.

With this paste : evap temp -97C, cpu temp -50C lol.

Already I use Geil Golden thermalpaste. Very good for ~-100C, not freeze and good contact evap:cpu.

DEVIL K-ce,
I have a tube of Geil copper colored paste. Came with my memory.
Is that the stuff you're using?
