Good catch there
. As the standard fans are 2500rpm models I would naturally assume it's better to go for the 2500rpm sp120s.

That what I did. I'll just install the sp120 over the stock fans.

No, the 2350rpm ones. They're really loud.

There are only 3 types of SP fan available from Corsair
Quiet - 1450rpm
Performance - 2350rpm
L (supplied with i series coolers) - 2700rpm
Don't know where you guys have gotten 1850 and 2500 from.

My L fans max at 2500rpm - so naturally I assumed that was the spec. Now you tell me they should run at 2700? No , honestly I couldn't remember the actual numbers - just went for the quick answer lol
Being 6% out in the figures is better than corsair are doing atm, and my fans

Usually with fans the quoted RPM figure is +/- a certain percentage. Corsair quote 2700 +/- 10% so 6% under is still within their specs.

The sp120's that everyone recommends for the H80i are 2350rpm. that's 350 rpm's slower, but everyone says they work well and have less noise then the stock fans.

The 2350rpm ones are really noisy, I can only assume people are running them off a fan controller or the mobo header as I can't get them to go below 1700rpm using Link, i'm happy to be proved wrong, (in fact I'd love it as I could actually consider using them) but i'd not recommend them as it stands, at 1700rpm they're as noisy as I'd tolerate running Prime or benching, at 2350 it's like sitting under Heathrow's flight path.
So i believe I'm right to say those that order the Quiet 1450rpm fans will run into problems. Either they won't be recognised at all or there will be problems controling the speed, because the controller expects a 2700rpm fan. I've been through the configs and there's no way to change the divider for the fans.
So, make sure you get the right ones.
2350rpm is not really too far out of spec. Only a hot intel will push it up there. Anyone with an AMD thuban has no worries in that respect.
*edit*
Gone back to the stock fans cos they don't ever run over 1450rpm so i don't hear them that much. and at idle they can run at less than 250rpm (that amazed me for a start), with folding only warming the my cpu to 41ish (don't expect this with intel - no way)

Well the stock fans are noisy too. I guess Corsair really messed up with the stock fans. Even after fw update their still whiny.
Soldato
I've yet to try the stock ones as everyone is whining about the whining. I'm still setting this PC up so i may have a play with them later in the week. So far the GTs are nice and quiet and do respond to Link, as to whether they'll be up to the job once I start overclocking is tbc.

Fantastic
thank you.Looks like i'll be getting the H100i, installing it with 4x Corsair SP120 Quiet fans and leaving it be.
Soldato
Just been told that a workaround is to use the 12 to 9v resistor that comes with the SP120s, brings everything down to a more manageable level.
Soldato
I've not got the H100i yet but I am running 2 SP120P fans on a Matterhorn heatsink. I'm using PWM to control mine though via a converter made by one of OcUK's members, Tealc.
Does your motherboard not do this for you ? Mine I can select voltage and set the PWM levels for the fans.... ?
Soldato
It does but I'd got the adaptor before I spotted the fan control options in the BIOS.
The adaptor is slightly better imo though as it's externally powered via Molex and my version (Tealc built to custom spec) supports 3 fans. I like the external powering as it's not loading on the mainboard as I'd have to use a splitter to run two fans as I've only one PWM socket.
I used ET6 to alter my fan speeds.
Fair enough sounds like it works ok. I run both SP120 fans from the cpu header on a splitter.
Most motherboards can supply 1A split across all the fan headers my Gigabyte Z68 board does. The SP120 performance editions at max are rated 0.18 A so running two on one header is well within the safe tolerances.

I'm very much an overkill specialist, hence the H100i replacing my current cooler, an Alpenfohn Matterhorn PURE with 2 SP120 fans strapped to it. It's MORE than adequate for the job. If I'm honest the H100i is more of a vanity/fanboi thing. My PSU, RAM & case fans are all Corsair and I want to match my cooler too.
Soldato
Sounds interesting, i've decided to stick with the Gentle Typhoons at the moment as they're fairly quiet even on full load and temps are excellent so far, i've not added too much extra voltage yet (still finding my feet with X79) but it's handling my 3820 fine.
