(H)EL 80/81 Heatsink - Compatible to Liquid Metal Pro?

Hi@all,

i'm planning to replace the cooling-pad of my hel80 against the Liquid Metal Pro or the corresponding colling-pad from Coollaboratory.
The only problem is, that Liquid Metal isn't compatible to aluminium-heatsinks ...
Now the question: does somebody know, which material Auras (Auras seems to be the heatsink-producer) used in our heatsinks?

thx!

 

it's copper core casted insides an aluminum-like material. just don't get any on the aluminum and you should be fine, I so far seem to have no noticable issues, smeared both on nvidia gpu and cpu. Just remember to put a very thin layer of it. Like really, REALLY thin. a wee brush is very good for applying it, that's what I used for mine at least.

good luck.

 

Hi guys just wanted to check if everything goes fine with that metal compound.
I'm planning on using it with IFL90. Thanks.

 

no unnatural growths noticed outside my heatsink, temps lowered. so to sum up, I'd reckon it's fine, hel80 here tho, but afaik the heatsinks are the same for both families, compound-wise that is.

just keep in mind tho that upgrading/removing a cpu later on might be quite a bit tricky since liquidmetal makes a stiff layer and sticks whatever it is in between of together in quite a decent manner.

cheers.

 

Thanks for fast replay. You probably don't remember it now, but what was the different between that you used earlier. And that was that "earlier".

We were thinking here in thread nearby, that since notebook coolers are highly inefficient, the thermal grease doesn't make much difference.

 

Well it *seemed* to make a big difference straight away, but I not only greased up the heatsinks, but also cleaned the fans etc. Plus, I opened it up and greased the nvidia cpu, like stated in my first post. I got my hel80 2,5 months old, 2nd hand.

Only if you grease the nvidia gpu as well as the cpu will you be having less fan time, imho.

Right now, with kernel 2.6.23-ARCH (2.6.24 will have TICKLESS for x86_64, officially, so I will have even less cpu work) I'm having fans on really rarely.

It's winter, and I have about ~20-22 degrees in my apartment, but if the vents are clean, the difference (compared to clean fans + 'original' grease + old kernel + old bios) is really noticable.

If you have the time, I'd suppose it's worth it. If for not anything else like the audibility of the fans, then for the longetivity of your cpu/gpu due to the colder run.

Cheers.

 

Awesome. But do you now the before and after temps?

Also, how diffifcult would it be to take it off, if you want to change the cpu for some reason?


EDIT: I also have the HEL80, and the fan-problem is a much worse on it. The fan starts from zero to almost fullspeed at 46 degrees celsius, and stops at 45, lol. So if you are browsing, and have hot room, the fan keeps speeding up and down.

 

Like I said, too many factors changed to give an exact change due to the applied paste. But I'd figure something along 5-10 degrees.

It's not that very hard, harder the longer it stays on tho. Generally, when I removed mine after applying the paste, it was on for only a couple of days or so, and I had to scrape it off reasonably hard.

But it grows harder onto eachother as time passes by so I don't know. Theoretically it's supposed to be as one.

You should update your bios to the newest version (1.21B or so), get a tickless kernel or whatever drivers window$ provides, and if applying the paste, apply it on your gpu as well - that seems to be the hottest part, the cpu seems pretty cool when somewhat idle (webpages/forums/etc).

 

Hi imachine, what product did you use and where did you get it?

 

eh.. you could at least try and carry out the effort to read the topic of the thread you're posting in. obviously I used liquidmetal pro.

 

Well, I changed booth interfaces and the difference is small or none at all. I would say approximately 2 degrees not more.
I noticed that GPU temperature now constantly jump up and down. Earlier it was almost all time 86 degrees and now it jumps from 82 till 86, depending on the scene difficulty. Either it the contact is so good, that the cooler very quickly takes of the heat. Or on another hand the contact is bad, since if it was good, the temperature should be approximately stable and equal to coolers and no jumps should be noticeable because of the large thermal buffer.
Maybe I should take it apart one more time? :/

Does your GPU temperature jumps like that?

 

you must remember that the liquidmetal takes some time to 'settle', i.e. at least 48 hours or so, generally the longer under stress, the better.

also you have to apply, like I stated before, a very thin layer of it -- too much of the stuff, and it won't transfer the heat, rather, keep it to itself.

it's only there as a means of heat transfer! it's not to dissipate the heat by itself! it also sort of 'blends' in with the cpu/whatever and the heatsink, allowing for better thermal travel, that's why it's so hard to get it off later.

so put as little as possible, make sure your vents are clean, and you should be ok.

remember to have your bios updated. the latest version works very nice for me. it's barely on (the fan).

I run about 40-45-50 deg with graphics in 2D.

the fact it jumps like that is because it takes a lot less time to cool the stuff now, as the paste transfers heat better than what you had before.

cheers & good luck.

 

Ok, thanks, it just that I expected something more.
I applied it just like you told, first got a year cleaner and with a small drop made all contact area crystal and cooler covered with it and then add just a little to make sure it will be enough. It has already past 72 hours since I applied it to GPU and made through 2 FEAR expansions, so it must be at its fool throttle now.
By the way the method with ear cleaner is very useful, you almost loose no metal but it covers very good and easy.
Happy new year to ya!

 

I wonder about the ear cleaners if they're absolutely sterile that is if they are properly clean not soaked in any cleaning chemicals, and another, if they're not the kind of cloth to leave some of itself when used.

I used a model-maker's brush, worked real nice.

as regards the 72hours, the way I see it, is it's AT LEAST 24 under stress, tho the longer the better (up to a week or two).

right now I'm having my EL80 sit on top of a leather couch with the vent in mid-air, and running on batteries, the fan is on like every 10 minutes for 3-4 secs.

that's Linux 2.6 + 1.23B bios.

 

The reason I asked is because I cant seem to find a seller stateside so I am looking for a retailer or an alternative.TIA
