2 quick questions:
1st: where can i get my hands on some as epoxy?
2ng: what's the best way to remove as epoxy and normal asII?

thanks

o yeah and

3rd: what's this new artic alumina stuff? is it better?

[ButcherUK]

1. er lots of places on the web, look around.
2. Normal AS can be removed with a mineral spirit (acetone is the usual), epoxy is pretty much on for good, if you have some on a heatsink you could lap it off though.
3. Artic alumina is not as good for cooling as AS, but apparently does better at low temps / high pressures (i.e. for TECs).

I have not seen any data on Alumina in high pressure applications. Note that Arctic Silver works well in high pressure applications. The primary advantages of Alumina are lower cost and due to its non-metallic composition, there is no capacitance. Translation, you can slop it all over your CPU or video card without repercussions.

I thought that one of the reasons they were coming out with the Alumina was that the Ceramics used in it's composition would not compress to the foil that has been reported by several people lately with Arctic Silver II. Basically, after a while, the stuff turns into silver foil and no longer cools at full capacity. One of the Arctic Silver guys, Nevin House said that Alumina would fix those issues.

Also, I see it as a competing product to Nanotherm, which is also ceramic based.

All in all, depending on the application, both could be possible solutions.

alumina is a phase change paste, desined for 1 use only

[Intraveinous]

First, I'll quote Nevin House of Arctic Silver's reply to the last time you said that alumina was a phase change paste for one use only.

Arctic Alumina Compound is not a phase change pad as found on stock heatsinks. It utilizes a bit of phase change technology to improve its performance and long-term stability, but can easily be cleaned off of the CPU or heatsink later. (Unlike a melted phase change pad.)

All thermal compounds are designed for single use. You're supposed to clean and re-apply every time you take your heatsink off.

Peace

okay cool, ill just steal some acetone from the lab for my asII.

but if im trying to attach a waterblock to my gpu and northbridge, (and for peltiers on my cpu waterblock too?) how should i attach them? i dont want anything permanent, so i can take it with me with different mobos and stuff...

With a mounting clip of some sort, some waterblocks come with a mouting device, others you have to buy separately.

for the dangerden gpu and chipset coolers, know how i would mount them?

They have a set of two lugs which you fit bolts through and bolt to the motherboard / gfx card.
