Heatsink modding

[Pelliculart]

Yes I saw that. My fault. Forget it.

For the heatsinks I took Arctic cooling two compound thermal adhesive.

Thank's ! I think i'll buy this.
Arctic cooling MX-4 or another reference ?

For the thermal adhesive it's 2 of this one ? : http://www.amazon.de/Phobya-XT-Wärme...ords=phobya+xt

The pad is right.

You may use this Thermal adhesive its Arctic silver (not Artcic cooling, sounds similar , sorry):

Yeees, excellent the minimachines website and it's in french ^^

Oups... for the thermal adhesive... it's been too fast and bought "Arctic Cooling ORACO-MX40001-BL" http://www.amazon.fr/gp/product/B004...ilpage_o01_s00
Do I need to change it and buy Arctic silver or I can keep my order Arctic Cooling ? No problem with electric static on my arctic cooling ?

Yes for shure. You have to fix the heatsinks with Thermal adhesive (most of them have two components snd a spoon two mix them) but you ordered thermal compound, This wouldn´t hold the heatsinks. You put that for example between a cpu and the cpu cooler, that is fixed mechanically.

Sorry I didn't understand what "Yes for sure" is for ? Minimachine

So, you are telling me that the thermal compound I bought is useless (no needed here) because here it's a thermal adhesive that we need to fix heat skins. Right ?
So I miss something to buy, I need heatskins ? Like them : http://www.amazon.fr/Alphacool-17155...tsinks+15x15mm ?) ?

[loko]

Sorry for the long post...

You can save money, with the same result!

That is nice! As it seems, my gut instinct proved to be right. 10x10=100cm², while 3x5=15cm², so we are talking about 15% of the original size! I guess I was right insisting on this subject.

Which W/mK?
I only found 3x3cm and only 1.2 W/mK...

Phobya thermal pads are among the best. The newer Phobya XT 7W/mK is almost not sticky, very hard, and not compressible, while the older Phobya Ultra 5W/mK is quite sticky, soft and compressible.

When the gaps are not even, or there is a chance that the thermal pad may slip, Phobya Ultra is recommended by all experienced users for better results, while when the gaps are even and there is a lot of pressure, Phobya XT has obviously better results.

BTW:
Thermal Adhesive Paste
- Arctic Alumina (Ceramic)
or
- Arctic Silver
?

No, I mean for the heatsinks...

Arctic Silver (both normal and adhesive) is silver-based (and partially ceramic-based), while Arctic Alumina is pure ceramic-based. Since Arctic Silver contains silver, it has slightly better thermal behaviour than Arctic Alumina.

The main problem is that while Arctic Silver is non conductive, it is slightly capacitive, while Arctic Alumina is both non conductive and non capacitive.

Whether you use a regular or an adhesive thermal paste, if you plan to attach a heatsink directly to a chip, and you fear that there is a possibility that the thermal paste will come close to any circuit, you have to use a pure ceramic-based product.

When you use a regular thermal paste on a CPU cover, there are no exposed circuits nearby, so you can safely use Arctic Silver. When you use an adhesive thermal paste, if you plan to remove a metal plate, attach mini heatsinks, let it dry, and replace the metal plate, you can safely use Arctic Silver Thermal Adhesive.

To anyone interested, here are some personal thoughts about thermal compounds.

Thermal adhesive compounds are worse heat conductors than most regular thermal compounds, but their use is required for non mechanical mounting. Two-part epoxy thermal adhesive pastes are better heat conductors than double-sided thermal adhesive tapes. On the other hand, thermal adhesive pastes may be impossible to remove without damaging components, while thermal adhesive tapes are easier to remove. If you want to be able to remove thermal adhesive pastes easier, you can mix them with regular thermal pastes, to achieve a compromise between adhesion and easy removal.

As far as regular thermal pastes are concerned, the actual temperature difference between using good and excellent thermal pastes is hardly noticed under normal circumstances, probably less than 5 degrees Celsius. This means that you can actually use whatever top brand thermal paste you like, unless you are overclocking or having thermal issues. Anyway, most of the times, the correct method of application is more critical than the theoretical characteristics of the thermal compound.

Since proper use consists of applying a very thin layer of thermal paste between two components under high mechanical pressure, while some top-range products, which seem to have better theoretical characteristics, have indeed excellent thermal behaviour while used under high mechanical pressure, they may have worse thermal behaviour than middle-range products when used under lower mechanical pressure.

Also, since some modern powerful GPUs may generate more heat than modern CPUs, while some thermal pastes may seem to be more than adequate for CPU cooling systems, they may prove to be inadequate for many GPU cooling systems.

Notice that low power units like Atom processors are not generating much heat, so using the best possible thermal compounds will not make any significant difference anyway.

Beware, Arctic Silver 5 is a very popular thermal paste, but while it is non conductive, it is slightly capacitive. Arctic Silver Alumina and Arctic Silver Ceramique 2 are both non conductive and non capacitive, though probably slightly worse than Arctic Silver 5. While Arctic Silver 5 was a top choice many years ago and still remains popular, nowadays there are many better choices, so it is considered a mid-range product.

Arctic Cooling MX-4 is also a very popular mid-range product (Arctic Cooling and Arctic Silver are different companies) and seems to be slightly better than Arctic Silver in all aspects. Noctua NT-H1 is another mid-range product, comparable with Arctic Cooling MX-4.

Moving to the upper-range products, IC Diamond (7 carat) is considered to be quite good, but reported to be very hard to clean. Prolimatech PK-3 is considered to be a top product. Gelid GC-Extreme is another top product, probably one of the best current choices. Phobya HeGrease Extreme and the newer Phobya NanoGrease Extreme seem to be probably even better, but they are not as popular and widely used as Gelid GC-Extreme.

Liquid Metal thermal compounds are the best possible, but hard if not impossible to remove. Indigo Xtreme and the newer Indigo XS are probably the best ones. Coollaboratory Liquid Pro and the newer Coollaboratory Liquid Ultra are alternatives. There are also a few more products from different companies. Anyway, these products are addressed only to specific users, for extreme overclocking situations.

In my system the function. but if you take any other heatsink its okay. If you put them, or one big cooler over the complete alu plate or dirctly on the chips a height about 13 mm will fit better. the plastic part that holds the mainboard limits the height of the coolers.

Maybe two like this ones:

so that's means you took

and not
- "Arctic Silver" http://www.arcticsilver.com/arctic_s...l_adhesive.htm (maybe ~ 7W/mK BUT NO electrical insulator)

I've bought Arctic Alumina.
Yesterday I've bought 4 products (high for my budget ^^), hoping I'll do something correct with it :
One thermal pad : http://www.amazon.fr/gp/product/B0051C287K
thermal componing : http://www.amazon.fr/gp/product/B0045JCFLY
thermal adhesive : http://www.amazon.fr/gp/product/B006WXOV7W
heatskins : http://www.amazon.fr/gp/product/B008LZO3NQ

It's ok with that ?
And do you think here (for the Pipo X7) the thermal componing will be totally useless ?

EDIT : Scooby-Doo, when can you upload pictures of your new installation ? I'm curious of that, it seems an nearly perfect installation

You will open the device, unscrew the PCB, remove the metal plate, remove the black adhesive from the metal plate, clean the metal plate with alcohol, mix two equal parts of the two tubes of Arctic Alumina Thermal Adhesive and use it to attach at least 4 or even all 10 heatsinks on the metal plate, being careful to attach them according to the right airflow direction, parallel to the long side, let it dry, put one piece of Phobya XT 1mm thermal pad on the processor, one on the power unit and a long one on the memory chips, and replace the metal plate. It will be better if before closing the device you put a piece of a 5mm thermal pad on the other side of the processor and the power unit. You do not need the thermal paste.

In my box the alu plate didn´t hold after replacing it so I fixed it with arctic silver, too. That means fixing the pads with thermal adhesive, like loko described. After that I put Thermal adhesive on the upper surface of the pads and fixed the alu plate with that. Onthe alu plate I now have fixed 8 of the little hetsinks, that I posted earlier. These hetsinks are a little bit to high, so that the meinboard bends alittle bit. everything functions, but it would be better to use heatsinks with a maximum height of 13 mm.

Now, waiting my tools, I've just open the Pipo X7 and I removed the bad brown pad like you can see here :


Now temperatures are a little better (like 2, 3°C best) but I'm still CPU throll likee 85°C when I load the CPU with FlashPlayer (or PopCorn 1080p). CPU temp down faster to normal temp when no use.
Their pad is really useless, what do you think ?

[Scooby-Doo]

I found a way to post fotos:







You can see, today I made some more mods:

- I cutted a piece aof the plastic holder to have mor space for my hetsinks

- I put a little rest of the Phobia xt 1mm cooling pad, so that the heatsinks get contact to the case

- you can see how small the mabo backside cooling pads can be with the same result like the big one

Result: base temp 33-34 °C for the cpu cores, after 3 minutes AIDA-Stresstest 41-46 °C, after 1 minute no more increase of the temps; 1 minute after stresstest temps 35-36 ° C,
after 2 minutes temps like before.

Tonight I will make a 2 hour VOD HD streaming run to see how the temps develop.
