Hi,

I'm building a new computer with a Core i5 CPU (probably a 3470) and I would like to cool it in a semi-passive way to keep noise down as much possible. By semi-passive I mean I won't be mounting a fan directly to the heatsink, but will have the rear exhaust fan take care of the necessary air circulation.

Now I was wondering which heatsink is up to the job. I was thinking about the Thermalright Macho 120 or even it's bigger brother the Macho 120 rev.a. Is this a good choice?

thanks
Nils

I used a Scythe Ninja as a passive and it worked quite well.

I wouldnt go with ivy bridge if you want passive cooling unless you really need the extra features it provides. I would recommend sandy bridge if its just performance that you want since it runs a lot cooler and its 3-7% slower than ivy, not a huge difference.

Please try Thermalright Macho Rev. A. which is unbeatable performance and quiet!

Are you using it with the 3570K Cpu? How well does it work (idle temps, peak,..)? And do you have the case fan sitting next to it like I'm intending to configure?

I had it with an AM3 CPU. I used the rear case fan as the "CPU fan". It worked quite nicely. I had the CPU overclocked about 25% too.

I use a mc3002gx and it cannot be heard , dead silent and keeps my AMD 1100t 20c cooler than the stock cooler @100% cpu use , was 60-63c now 40-43c . And it is dead silent . Not sure passive cooling is a good idea on that chip .
