Just wanted to say that Xbit tested a very nice totally silent system. Take a look at the CPU cooler, it's mind bogling huge...

On their heat test with the fanless heatsink, it looks like the CPU is throttling? I'm not sure why but the temperature drops signficantly several times. It's not normal behavior.

An interesting concept, but ultimately it's a waste of money when silent fans are so much more effective, cheaper, and (still) silent.

You saw something wrong there, or didn't follow the article correctly...

This diagram on this page shows how this NoFen set works with Intel Core i5 2500K, 95W TDP. As you can see, there is no throttling whatsoever, and maximum CPU temperature is 52 degrees celsius, which is an excellent result.

Now, in this diagram on this page, which you are referring to, the CPU being cooled is Intel Core i7-980X Extreme Edition, which is dissipating 130W TDP, and NoFen clearly stated that their CR-100A passive CPU cooler can cool CPUs up to 100W TDP (they even put '100' in the name). So, this is pushing-beyond-limits kind of test which is not a normal usage case for this 'Set A40' anyway.

And no-fan is just no-fan! Period. They can build evermore perfect fans but they will always: vibrate, make noise, collect dust, deteriorate, and be an ultimate single point of failure.

Yes it's too expensive. I can't buy it but it looks silent. :)

Isn't the HS itself only $100~?

Hi all, I think this is a breakthrough - a cooler able to passively cool even a hot six core CPU at "full bore" - I am impressed and considering to buy one. However, one remark in the xbitslab review (post #1 ) surprised me a lot:.."...numerous fins made of 2mm aluminum wire...".... :? ...wow, could it be that simple..?! and if true I fully agree that the price is a bit too high. Anyone out there who knows more..?

Well, fins made of aluminum are fine. A number of HSFs are simply aluminum with a copper heat pipe inside. The size of this HSF is what sets it apart.

As for more info, it's not that fancy, it's just a huge HSF with a lot of surface area on small fins. I'm also wanting to buy one but availability is only Europe and Asia for now. Shipping to NA would cost a lot I think.

Lsv, I am still NOT convinced since Nofan use the term "ice pipes" to describe the cooler principle. Where are they..?? :o ..
My immediate thought as a chemist would be they are rather tubes filled with a substance having a suitable melting point. Heat of fusion/melting can be rather impressive if you pick the right substance. But that is just a guess and the cooler is a bit too expensive to buy one and cut it apart..... :wink:
