I wonder how many more fans they would sell if they made the fans in all black.

However, I might be tempted to take some spray paint to it lol.

Painting them effects performance, but dying them doesn't. There is a guide around here somewhere on how to do so. However, I wouldn't do it. A lot of people complain about the color just because its not the typical black, blue, red, green you see in almost everyone's build. Im doing a new build in a few days when the stuff gets here that should fit the color of Noctuas very nicely.
Also its nice when you see a Noctua, you know its a Noctua.
And the rubber mounts are easily removable.
Im not a scientist, and will not even try to say this as fact. But, I don't think compensating for 20C ambient works correctly.
When he tested the H100i it was in 10C ambient. So he added 10C to his temps to make up for it not being 20C. Now that may work fine for air coolers, but I would think a radiator would be more efficient in cooling in cold ambients then warm ambients,

I actually just thought of this, maybe the both of them assembled all the fans on the PWM switch and put them on a single header. You do that, when you turn down the RPM you're turning down the pump. If they reduced the flow in the loop well below what you need, I can see temps spiking like this.

He said he had the Noctuas plugged in at 7v using the LNAs. He also tested with the pump at 100% and on PWM, and there is virtually no difference.
I would assume he either had the stock fans at 100%, or PWM, either way I don't see it being 20C difference.

at 55s on the linus video the helix fans look like they would be pulling air up through the rad
yet on swiftech website they look like they would be pushing air down through the rad
could he have mounted the helix fans the opposite way round from the noctuas?

He and Martin, as well as other have shown there is virtually no difference in push vs pull. Pull is used so dust doesn't cake up on the rad. He always uses pull/exhaust orientation.
I guess it could be possible the Helix fans are designed in a way that they don't do as well in pull, but Ive not come across a push vs pull test that shows a noticeable difference.
Ill be testing all of these scenarios when the stuff gets here.Edited by CTM Audi - 3/1/13 at 10:38am
