    Forgot the link? :eyebrow:

    The effect of swapping fans is very interesting, nice you did that test.

    Wonder where a Taisol 760 with the same fans would come in? :cooldude:

    Putting my metallurgist hat on, pure (or commercially pure) aluminium is quite soft and has the best conductivity of the aluminium alloys, so it's probably that on the Asaka. Cold-working of extruded sinks makes the metal harder.

    Nice review, got my HHC-001 at 7v so its running about the same speed as that one. Top notch cooler, only a shame there isn't a nice 80mm version so you can get even quieter fans for the same airflow :)

    Very true :)

    I thought about cutting the heat pipe off to see if it really made a difference too, but I didn't want to destroy the heatsink ('tis nearly competition time, don't tell anyone though ;)), cheers,

    nice review m*

    is that a oregon scientific clock reflecting in this pic its displaying 33oc

    You almost get points for observation skills ;)

    What you thought was the temperature is actually 'OFF' - telling me the alarm's off. The temp is shown below it, 20 degrees in the pic :)

    No need to, it has already been proved that it cool exactly the same when the pipes are removed...

    So would you say the theory is wrong or the impementation was poor?

    The theory is fine, so it must be the implementation. The main problem is that different motherboards and cases mounts the heatsink in different directions. For it to work properly the heatsource must be located below the coolant in the pipes so in theory it should work best in a desktop computer. Then that copper is such a good material at transfer heat that the top and the bottom of the heatsink has the same temp makes it worse since it is the temp difference that is used to have the liquid inside to vaporise over the core and condensate at the fins. How will that be done if all of it has the same temp? And also to find that sweetspot for the colant to vaporize must be hard since different CPUs creates different temperatures. I personally think it is required to tailormade each hsf for their specific purpose, OC:d and not OC:d CPUs to start with. Then to use big copper aluminium hybrid hsf:s so the top of the fins will be a lot cooler then the core part. Ah well, I think you get the idea. ;)

    Me too... :) You're right about the setup being very specific for different systems too, there's no way to escape that sensitivity without having a forced pressure change (like in a fridge).

    Still they tried, and for a copper heatsink it doesn't perform too badly ;)

    Can't you slap a fan adaptor on and then stick an 80mm on?

    Be interesting to know, as I have a HCC-L61 on my XP2000, and MBM reports 60c at load. Although this is rock solid stable, and never cimbs above this, I'd like a little cooler (just in case I overclock at some point)

    60 degrees is well hot... the xp2000 shouldn't be any hotter than my 1.4 I don't think. Though I guess mine would go that way if I stripped it of case fans.

    I doubt a fan adaptor will change your life any, the process of putting the obstruction infront of the 80mm fan generally lowers their output to less than 60mm's (never seen a fan adaptor review that I trust where the temps improved more than 1/2 degrees with the adaptor).

    I'd just go for a better 60mm fan, you can double the airflow for not a lot more noise, see how well the block did with the sd fan I used inthe review :)
