Great test, for me running the intel stock cooler always has included undervolting, and using program i can get the fan really quite when adjusting after boot. i guess with undervolting u could go lower, maby down to 5-6V

did a quick undervolting test with I7 920

Interesting article, good to see how the stock heatsinks really perform.

At how many RPM does the fan run when set to Q(uiet)? Did I miss that in the article somewhere?

Hmm, interesting. If it came with all i7s, a simple $5 fan mod might be enough for some people.

It was mentioned briefly on page 6.

Page 6 wrote:
The built-in speed switch toggles the fan speed between 12V ('P' setting) and 7V ('Q' setting).

An AMD followup would be fantastic

Very interesting review, Lawrence!

Look how much more aggressive the angle on the Intel fan blades are than the Nexus

vs
Image

No doubt the Intel fan is designed to move a lot more air. The angle of attack near 45º suggests that the incoming axial velocity is designed to be essentially equal to the rotational velocity of the fan blade tips.

It looks a lot like this kind of fan, to me.

This cooler is such a joke... a shame for Intel I think. Maybe they only simulate the fan behavior and never turn it on !!! It's the first time I've had to turn the sound down when listening to a sample at 12V !

Someone beat me to it -- the i7-980X fan has incredibly steeply angled blades! No wonder it is so noisy! They are beating at the air; rather than "slicing" it...

Sounds like it would make a good helicopter.

That angle combined with the lack of a radial "hook" curve and shroud I bet a lot of the moved air is pushed out at the sides before entering the heatsink.
