what Fans for my H100?

subbed... I am looking for the same sort of information. Maybe I will take some advice from here before I order 4 Panaflo H1A's and turn my computer into a jet engine.

edit: There was a post a while back with a google docs link showing which fans are compatible with the H100 controller. Not all are. The 2 generic fans with mine, for instance, will start and run full tilt and then slow down and stop for a few seconds and then fire back up. Apparently its an issue with the controller block and the way it controls fans. I am away on course or I would check my desktops favourites.. Hopefully someone can link it again.
 
A little while back somewhere had an article on this and the default fans shipped with all Corsair H units were the best ratio of pressure to noise, I love the vortex fans got a few myself but they do not do the greatest behind thick resistance (a rad counts as this) The only fan I could think of that might do well in this really are the newest Noctua ones (4th generation I believe they are really fancy looking compared to previous designs) Scythe GT or Coolermaster Blademaster V2 if they are shipping yet.

Those helix ones simply do not at all look designed for anything but open airflow or behind a touch of mesh, all the good pressure/mesh ones I have seen are less blades and much less sweep to them the only exception I am personally aware of are the Scythe GT fans which these look pretty much identical and very close to the same performance figures.

You talking about pressure:
the Vortex is 2.2
the Helix is 2.29
the corsair is 3.1

are those numbers not enough for the H100 rad?
 
bet you anything those are open air pressure figures, I know many folks use Scythe GT on rads due to good pressure to noise ratio, I am not going to quote specific numbers cause I have not tested myself, I do know however the Vortex are awesome fans but the lose a lot of the pressure they have when impeded unlike say the blademaster fans, similar absolute pressure numbers until constricted blademaster and similar fans do not lose nearly as much available pressure.

Just looking at the design of the blades and the sickle like curve to them, I have a feeling many of the fans like the Helix(GT) some of the similar slienx and even some of the noctua and similar designs(like the vortex) the extra added features to reduce turbulence also hurt their ability for absolute pressure cause they simply are not designed for pressure, they are designed for reducing noise while retining as much airflow as possible, not quite the same thing.

Like said, article if I could ever find it, believe the fans they bundles with the H100, Panaflow, Delta, and I believe also Phanteks something or other retained quite close to their rated numbers, where many others simply did not when constricted. So, try to help me source the article, and you will see there is very few fans comparable then the ones bundled in, lower noise for sure, but it will hurt the performance as well, I would get lower speed on the bundled fans, swap for noctua or something but it certainly is going to hurt performance for a possible better noise profile.

Turbulence, restriction, vibration all kinds of little things mess with these numbers, very very few fans are pressure and flow, unless you don't mind earbleeding noise :)
 
I have a 140mm cougar fan that has significan bearing noise when undervolted but when running closer to max rpm it just turns into whooshing air noise.

I have the quiet edition of the corsairs undervolted to 7V and they're silent enough that I only have pump noise (and that's very quiet too) on my coolermaster seidon 240m AIO. I'm at 4.5GHz 1.28 volts and my temps to up to around 55 to 60 degrees when gaming, ambient is 22 to 23 degrees.
 
I've got Corsair SP120's on my H100i and I love them to death.

Everyone has different tolerances though for noise level/pitch and a fan controller helps a ton to keep things quieter.
 
i think i'm gonna give the Air Series SP120 High Performance Edition High Static Pressure 120mm Fan a try. I'll get 4 of them for push/pull

Make sure you want to get the High Performance Edition and not the Quiet Edition. RPM is doubled with the HP ones, and thus noise.
