Silver is not the best heat conductor. See here : http://hyperphysics.phy-astr.gsu.edu/hbase/tables/thrcn.html

Ok, back to physics 101.

Copper is superior to aluminium in terms of heat conduction (Thermal conduction)
Aluminium is superior to copper in terms of heat absorption/dispersion (specific heat)

Refer to the following hyperlinks:

Aluminium & copper heatsink (This is interesting!!!)

Summary : Copper for the base to collect the heat quickly. Aluminium for the fins to get rid of it.

P.S. Yahoo! My noctua is in this setup!!!!

That's true. We're already into discussion about thermodynamics!!!

The discussions were theorectical and what we need are hard facts. If two heatsink of identical design, heatpipes + aluminium fins and heatpipes + copper fins (disregarding weight), who would win? Any data?

This cooler has a lot of space between the heatpipes and the heatsink base (especially at the base). Would it help if these dead spaces were closed up? I mean solder it up or put thermal paste?

As with other heatsinks, I notice there is a flat surface at the base. Have been wondering whether cooling would be improved if one were to stick a heatsink over the base....

Errr.... the link is to a sony mp3 player la

One thing about this cooler is the uneven distribution of heat. I mean, since aluminium is different to copper in terms of heat conductivity and heat specific, this would create different temperature on the IHS.

You know, one stripe of hotter area and one stripe of cooler area.

Well, I guess not so much on the proc itself as the IHS is the one with differential temperature but would it be good for the proc?

I was just wondering about that. However, I just can't put my hand on the base of my noctua heatsink to see whether it is hot to touch or not (no space!!!). If it is hot, I believe that another heatsink would help.....

@lohwenli - aiyoo! I don't mean using a stove to heat up the heatsink for soldering la!!! Lucky for that guy that did it!!!

What I mean was using a soldering iron.......

Cool, cause I've just order one from bulk!

However, the title is not good. Not many people would know what a DTH is.

@TS, can change the title to something that is easier to understand?

I know la....was referring to lolhalol!

Wah! 10'c lower than the HR-01!!!

Where did you get your xigmatek? For how much? Is it the S1283 or the S983?

Errr..... any heatsink would perform better without the side casing la....

@maknok - quick give us some feedback on the xigmatek!!!

@MakNok, thx for the feedback! I can't wait to get my hands on the xigmatek S1293!!!

Wahlioa! So brave aaa..... If you happen to rupture the heatpipes, then the heatsink would be so defective!!!

I think if he just remove a few of the top fins, it won't make much of a difference. The reason is that the top fins are usually cool! Even on my noctua, at core temp of 60'c, the top fins are still cool.....

Hey, if you're seriously thinking about experimenting, here's a suggestion to see whether the heatpipes work or not.

Just saw off all the top tubings, you know, like your broken tubing. Then turn it upside down just to make sure there's nothing in it.

If your theory is right, then the heatsink will still function as before..... But I doubt it.....

Alright! Here's another review of the xigmatek S963. Not a bad performer considering that it is the 92mm version.

I wished there were other reviews on the S1263.....

Nice. The HSF looks nice but your lighting is superb! Like professional photographer!!!

Err.... the temperature is for the S963 or S1283?

So can lend us the samples for review aaa?

Bulk is a bit slow la. Maybe you should put it in your sig so that other people can see.

Ya ya! Our bulker is willing to lend his sample for testing! When is your next roundup? Tomorrow?

Aiyoo, it would be great to have the TR 120 extreme too. So when are you planning to do it? Really interested to see the results!

Here's a new review on the xigmatek S963 : http://www.xbitlabs.com/articles/coolers/d...k-hdt-s963.html

It even beats a scythe infinity in a closed system case (although needed higher fan speed). Remember that this is the 90mm version with only 3x 6mm heatpipes.

The authors did conclude that the S963 heat dissipating area was not large enough to accomodate the Q6600.....

Can't wait to see the review on the 120mm version (Xigmatek S1863) with it's larger surface area, 120mm fan and 3x 8mm heatpipes!

Here's another review in German! Includes the Xigmatek S1283, TR 120-ultra extreme and water-cooling. Really exciting to know the performance of DTH coolers!

http://www.hartware.de/review_723_7.html

I've taken the liberty to translate the words (from google translater) although I wished there was a review in English!!!

Messwerte - Measurements
K = Kelvin (dunno why use kelvin instead of celsius )
Wasserkühler - water-cooling
Ultra-Silent Luftkühler - ultra-silent air-cooler
Non-Silent Luftkühler Beispiele - non-silent air-cooling (? at 100% fan speed)
Geräusch - noise
deutlich hörbar - clearly audible
Sortierung nach besten Differenzwert unter Last - Difference in temperature under load ???
Raumtemperatur - ambient temperature

Anybody who know german pls translate the conclusion!!!

LOL. I did use google translator on the conclusion!!! I actually wanted to paste that translation but eventually decided not to. However, the translation was adequate enough to gather some conclusions on the S1293.
