On page 1, the "incompatibility list" includes AMD socket 754. This is wrong. 754 mounts exactly the same way as 939/940, and these three are collectively referred to as "K8" mounting.

It looks as though the AMD clip can be mounted in 90 degree increments, but the clips would be under the fins if blowing at the exhaust fan. It appears mounting would be difficult in that event. Perhaps easier if the mobo is removed from the case?

Hi Mike,

Quote:
A mounting plate (made of cast steel or aluminum) sits on top of the base, holding everything in place.


A quick check with a magnet would test whether it is steel, or not. I'm guessing that it is cast aluminum, or some other non-ferrous metal.

The cross-flow between the fins must be helpful: the Ninja, and th HR-01 and this HS have it.

Next time you test a heat pipe based cooler, try orientate the motherboard differently to see how it affects heat pipe performance. This might be a weak spot for heat pipes, as they partly depend on gravity forr their operation. Whats the performance gain/loss between mounting it in a tower vs. desktop chassis?
(I'm building a computer where the motherboard is placed upside down, so I would be particular interested in getting some comparison with this particular orientation.. :))

i doubt there will be much difference. modern heatpipes rely on the internal wicking material to bring the coolant back to the evaporator, not gravity.

Is the FZ120 compatible with the BTF80/90 LGA775 backplate, so that the latter can be replaced with the former?

I have the BTF90 and the mounting hardware looks identical so I would think so. You'd have to hope the back plate doesn't "escape" down the back of the motherboard or you'd have to have the motherboard out anyway!

If you take a look at page 4 of the XP-120 review you'll find that SPCR did just this test. The conclusion was that it made no difference, the "wick" in the heatpipe(s) brings the fluid back to the hot end fast enough. I doubt any modern coolers use heatpipes that would have a problem with any orientation.

So, if I get this, what Intel CPU do I dare getting with a not so high airflow in my case and running it passive?

I currently have a C2D E4400 and is satisfied with it, but my cousin will be gaming more then me, and he wants me to get something for him so im thinking of getting a easy to install option that runs passive and is great for gaming..

Not sure if this is the best option, so im asking for your opinion. :)
Is is a good buy for me?

Sorry for digging out such an old topic ,but i just got myself one of these and i was thinkink what's the best mounting position for it? I have an Antec P183. Should i mount it so the CPU fan blows the air through the top exhaust or rotated 90 deg. so it blows warm air out through the back exhaust?
Thanks

Alex, the advice is to use only one exhaust fan for the case, either the top fan or the rear fan. Then you mount the cooler so that the air flows towards your chosen exhaust vent.

Cheers
Olle

Done. I mounted the ZEN 120 so the fan blows the warm air to the rear exhaust. I get about 34 deg. C on Q-Fan mode (PWM) with my E6420 @ 3.0 Ghz. And full load at maximulm 50 deg. C. Pretty good.
Thanks
