Nomanor Posted July 20, 2012 Share Posted July 20, 2012 Their top speed is rated at 2350 RPM Any idea if I can drop it with a Fan Controller? For example, when the system is idle, would i be able to dial down the speed to 1400 or something? Link to comment Share on other sites More sharing options...
peanutz94 Posted July 20, 2012 Share Posted July 20, 2012 Yes, you can control them with a fan controller. Link to comment Share on other sites More sharing options...

Nomanor Posted July 20, 2012 Author Share Posted July 20, 2012 They also ship with an in-line resistor that will drop the speed approximately by half. So there is no reason to buy the "Quiet" version, i can just get High Performance and drop the speed when needed, right? Link to comment Share on other sites More sharing options...
G50EED Posted July 20, 2012 Share Posted July 20, 2012 Well not exactly. The in-line resistor is a separate cable that attaches to the regular cable. To vary the speed at will means you'd have to go into your case and remove the resistor cable when you wanted to increase the speed (and the reverse when you want to slow them down). So if you want to vary the speed on the fly then, yes, you'll need a fan controller. I apologize; I realize now I misread your original question.

Shaw Posted July 21, 2012 Share Posted July 21, 2012 I recently purchased one of these Fans for some reason my motherboard monitoring software (AI suite Thermal Radar) and the bios doesn't sense it and reads 0 rpm even though it actually spins up physically. Faulty fan? or to do with my mobo? I've tried all the other fan headers which pick up my other fans, just not the Corsair SP120 high performance.

peanutz94 Posted July 21, 2012 Share Posted July 21, 2012 There may be an issue with the tach lead on the fans wires. I would say replace it if you can . If it doesn't bother you keep it. Link to comment Share on other sites More sharing options...
Shaw Posted July 24, 2012 Share Posted July 24, 2012 Blah, Took my fan back and it seems to be working fine on their Asus motherboard, They suggested a bios update and a CMOS reset, Completed both of those tasks and its still not reading the fan... So puzzled. Link to comment Share on other sites More sharing options...
parsec Posted July 24, 2012 Share Posted July 24, 2012 Are you using another monitoring program at the same time as AI Suite? If so, that is the problem. AI Suite can get confused when another program is reading fan speeds or temps. Have you tried the fan on any other fan headers on your board? Some AMD board fan headers have optional settings such as PWM or voltage control which must be set for whatever fan you are using. Link to comment Share on other sites More sharing options...
Shaw Posted July 24, 2012 Share Posted July 24, 2012 No other monitoring system is being used, tried every fan header on the motherboard, all the the other fans work fine but this one. even in the bios it reads as N/A, however it does sometimes flicker for a split second showing very low rpm like 50 or so then goes back to N/A. I even attached the voltage step down adapter to the fan to no avail. My motherboard just can't recognise/monitor this fan in any header even after a Bios flash and CMOS reset. which is silly because my motherboard is bearly a year old.

mofo88 Posted January 24, 2013 Share Posted January 24, 2013 it sounds like you have monitoring disabled in either the bios or in ai suite itself. there is an I in a circle on the side if that's enabled it won't monitor it. Link to comment Share on other sites More sharing options...
Appok Posted January 26, 2013 Share Posted January 26, 2013 I just picked them up and slapped them onto my H80i and i connected them to my motherboards CPU fans i use a Asus p8z77-v mobo and now there quiet running at 1600rpm now i can actually tolerate them, i use to hook it up to the corsair link and they run at 2000 rpm and sounded like jet engines Link to comment Share on other sites More sharing options...
mofo88 Posted January 28, 2013 Share Posted January 28, 2013 They aren't compatible with the h80i, that's why. Although, I thought they released a new firmware to enhance compatibility, but I can't confirm. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted January 30, 2013 Corsair Employee Share Posted January 30, 2013 Although, I thought they released a new firmware to enhance compatibility, but I can't confirm. That would be on a later version. For now, only the H80i stocks fans will be the only fan that can fully utilize the fan controller on the cooler.
