Hi all !
I want to buy this HS, but my mainboard is socket A (with a hot palomino).
I want to be able to rotate the HS so that hot air go out of my case, through my 120mm, but I checked and my socket is not well oriented to do that !
As you understand, the scythe cannot be rotated as I want on socket A platforms
Is there an easy way to make it ?
What accessories bundled with the katana can I use ? (as you understand, the traditionnal socket A clips can't be used in my case...)
Should I modify, drill or whatever some bundled components ?
Oh ! and I forget :
I've got the four holes around my socket
Please help me in my project,
Thank you very much for any reply,

Any idea why it doesn't list S939 with A64? Is there any reason it wouldn't work? I can't imagine there could be one...

I managed to find the Katana in a few places in the US. Not sure if any of them ship to Canada though.

Out of curiousity, would it be possible to mod the K8 base to fit AOpen's i915, MicroATX board for Pentium Ms? The holes are 56mm apart on the diagonal, I think. I have a modded Thermaltake on there now (well, I will when I get it back from AOpen's RMA shop, but that's another story) but I'm concerned that it overhangs the CPU socket so much it's blocking airflow to the components near it. Looks like this might be a better option, if it fits.

As far as bang for the buck, I still don't see that you can beat the Zalman though.

They're going to release all copper Katana, but I suppose there's no much advantage in low airflow situation
ahhh..thanks for the pics -where'd ya get those?
Well, the non-Cu is 300g - which is the "recommended" limit for Socket 462 retention clips. The Cu version is 502g - almost twice the weight.
I know that Cu dissipates heat better, and that's why I got that one...but now I'm wondering if I should have gotten the AlCu version.....
I wonder if I really want to test the clip, especially as I'm mounting this vertically (in a tower, not a desktop).
Hmmmmm.........

Technically the copper version "absorbs" the heat better. Copper isn't as good at "dissipation" of heat as aluminum. As a passive cooling device, the inclusion of aluminum is generally a vital contribution to good heat dissipation.
Look at the Scythe Ninja, and the top thermalright passive coolers (XP-120/90)(SI-120/90)
They all include aluminum to dissipate the heat. As copper is better at absorbing heat, it also is better at retention of heat. This is why "all copper" (meaning 100% copper) heatsinks generally require fans to be successful. Of course this is a generalization based on simple science.

This is completely incorrect, a much REPEATED myth that needs to be squashed out of existence. This has been stated way too many times in these forums and on the main site for people to be unaware of it by now:kenji wrote:Technically the copper version "absorbs" the heat better.

THERMAL COEFFICIENT INDICATES THE EASE WITH WHICH HEAT CAN PASS THROUGH A SUBSTANCE. IT DOES NOT MATTER WHICH 'DIRECTION". COPPER HAS A MUCH HIGHER T.C. THAN ALUMINUM; IT ALWAYS TRANSFERS HEAT BETTER THAN ALUMINUM, WHETHER COMING OR GOING. PERIOD.
When aluminum and copper are used together in HS, it's almost always to keep mass down.
All things being equal, if one imposes a maximum mass limit (say 600g), with a low airflow design, the total area of cooling surface is usually more important than the TC of the material. Thin aluminum fins allow for a larger cooling surface area than copper of the same mass.

The aluminium cooler will cool your CPU just as efficiently as the copper one, and with less risk of damage to the motherboard.do you think I should get the lighter Al-Cu version (300g) for my Socket A (no holes) motherboard, or is the added weight of the all-copper version (520g) ok for just a retention clip on my Gigabyte 7N400Pro?
Theoretically, the heat from the CPU should travel faster through the copper heatsink than the aluminium one (as copper has a higher thermal conductivity than aluminium) but the main determinant of cooling performance in fan-cooled CPU heatsinks is surface area; in this case the surface area of the two heatsinks is identical, and the performance should be also.Btw, what's the point of the all copper if they perform essentially the same?

My question would be, how will this Katana HS work as a passive cooler (with the fan taken off)?
Aight. I got myself a Katana Al, and I been running it without Fan.
My CPU temperature is running at 51 degrees (IDLE) to 61 degrees (after running Super PI for around 20 minutes)
Here is my setup:
AMD Sempron 2200+ (1500MHz)
Case: Antec P180
Motherboard: ECS 741GX-M
Memory: Generic PC3200 512MBx2
Video: ATI Radeon 9800 Pro
SCSI: Adaptec 39320-R
HDD: Seagate Cheetah 15k.3 36GB, Seagate Cheetah 10k.7 72GB
PSU: Antec Smart Power 2.0 500W (yes I am planning to add about 2-4 more HDD later on)
Cooling: 1 Nexus 120mm Case Fan, 1 Nexus 120mm front side Case Fan, 1 Nexus 120mm lower HDD chamber case fan.
