sinnedone Posted May 22, 2013 Share Posted May 22, 2013 OK so like the title says, I recently purchased "4" SP120 PWM 4 pin edition (2 twin packs) to replace my 3 pin SP120's that I had purchased for my H100i back when released due to noisy stock 3 pin fans (SP120L's) So I install them and update the firmware as instructed to the latest and low and behold, THE H100i DOES NOT SPIN THEM AT MAX RPM! The most the H100i will spin them is 2000-2050 rpm or so. MAx is stated at 2350 rpm. What gives Corsair? I spent 120.00 us for the H100i, 60.00 bucks for SP120 performance 3pin fans to replace faulty oem fans before 4 pin PWM SP120L's were available. Could not get proper control over the 3 pin SP120 editions without a voltage reducer on the H100i, now I purchase your own SP120 performance edition PWM fans and the H100i still doesn't work as expected! I've probably spent 270.00 dollars total on these products including shipping charges. I'd like to know if the issue of the H100i not spinning these SP120 PWM to 2350 rpm is a known issue, and if so when will there be a fix. I'd also like to know if there is anyway I can send back my 2 twin pack 3 pin SP120's for a refund being I had to purchase new fans not once, but twice. I don't want to come off as a pist off peckerhead, but when you spend this much on what was supposed to be the best all in one solution its a little more than disheartening. I Could have gone with a custom loop for the amount I have dished out so far on Corsair products. Not to say they are bad products since I own a corsair 850 power supply and 16gb 2133 corsair vengeance ram as well and all have been good so far. (knocks on wood) I would just like these issues rectified. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 22, 2013 Corsair Employees Share Posted May 22, 2013 What version of the software are you using and are they connected to the H100i? And did you purchase the 3-Pin SP120's from us? if so please start an RMA for those fans and explain that you would like to return them and include your order number.

sinnedone Posted May 23, 2013 Author Share Posted May 23, 2013 I am using the latest build Version 2.3.4816 with the latest firmware 1.05. All 4 SP120 pwm plugged into H100i No I purchased the 2 twin packs from an online retailer. How shall I proceed? Thank you Link to comment Share on other sites More sharing options...
Corsair Employees COOL GUY Posted May 23, 2013 Corsair Employees Share Posted May 23, 2013 All fans sold have the RPM specifications in free air. Once the fan is installed on a radiator in a case there will be varying degrees of restriction which will drop the RPM of the fan. There is also a 10% +/- variance in the spec of RPM possible. A easy way to check out the fans you have is to take one of the fans off of the radiator and hold it in free air (no restrictions) and verify the RPM of the fan in the software. If it is 2350 (+/- 10%) the fan is working as specified. Link to comment Share on other sites More sharing options...
sinnedone Posted May 28, 2013 Author Share Posted May 28, 2013 This is understandable, but the mother board spins the fans mounted to the radiator 250 rpm faster giving me 2250 rpm mounted on the rad. Maybe some testing needs to be done on this combination by corsair to see why the H100i isn't spinning the pwm SP120 to max rpm. Please advise.

sinnedone Posted June 13, 2013 Author Share Posted June 13, 2013 Corsair hasn't been very active on the forums and would like some help with this or an official stance on the subject at least. Link to comment Share on other sites More sharing options...
wytnyt Posted June 13, 2013 Share Posted June 13, 2013 they've been here everyday addressing issues but apparently their making good improvements as complaints have been way down as compared to a few months ago. Link to comment Share on other sites More sharing options...
sinnedone Posted June 13, 2013 Author Share Posted June 13, 2013 Ive been checking everyday and except for yesterday I haven't seen very much activity. I guess im going to have to get put on hold for a while until someone actually picks up. Link to comment Share on other sites More sharing options...
wytnyt Posted June 13, 2013 Share Posted June 13, 2013 not sure what more can be done,both coolguy and ramguy both have answered.putting your fans on the m/b vs. the Link is different as one is voltage control and one is pwm,so its expected to have different ratings. not much activity as theres not many problems to address Link to comment Share on other sites More sharing options...
sinnedone Posted June 13, 2013 Author Share Posted June 13, 2013 no sir, motherboard pwm header only does not control voltage and can get 250 more rpm out of the same fan mounted in the same position. Link to comment Share on other sites More sharing options...
wytnyt Posted June 14, 2013 Share Posted June 14, 2013 would you think it would be practical if i were to rma my 3 link systems because i couldn't fit all the device icons in the console? the link commander can handle 8 nodes,each with 5 fans and 4 thermals which would amount to over 80 icons and no way to fit that many one one console.

wytnyt Posted June 14, 2013 Share Posted June 14, 2013 simply a hypothesis and a bit of late night sarcasm is all.my question cant be answered any more than yours can no fans will spin the same rpm due to friction,tolerances and even the minute differences in blade weight.

sinnedone Posted June 14, 2013 Author Share Posted June 14, 2013 No I understand that, but the same fan mounted in the same position should then max out at the same rpm regardless of where it would be connected to, wouldn't you agree. Link to comment Share on other sites More sharing options...
wytnyt Posted June 14, 2013 Share Posted June 14, 2013 yes as a rule i would and the only difference i could come up with is the fan plugs to the m/b which is an unshared port basically dedicated only to that port,whereas the fan gets plugged into the hydro or link where the overall power is shared between fans and the overall functions. perhaps corsair rated the fan from a test bench and not hooked to a link Link to comment Share on other sites More sharing options...
sinnedone Posted June 14, 2013 Author Share Posted June 14, 2013 possibly but then that should be an amperage issue then not really a voltage issue. regardless a real answer would satisfy and whether or not its possibly fixed or that's just the way it is. Get what I'm saying. I mean I could sit there and measure voltage to a fan from both the h100i and the motherboard, but what if voltages are the same? then the h100i simply cant supply the amperage needed for 4 fans and the unit itself physically, or possibly a pwm issue with the h100i itself.

Corsair Employees RAM GUY Posted June 14, 2013 Corsair Employees Share Posted June 14, 2013 Fan RPM is done by voltage and Cool Guy already addressed this in one of his previous replies A easy way to check out the fans you have is to take one of the fans off of the radiator and hold it in free air (no restrictions) and verify the RPM of the fan in the software. If it is 2350 (+/- 10%) the fan is working as specified. Link to comment Share on other sites More sharing options...

Ok I've double checked this statement and understand it. Unless the H100i is sending say 12.0v and my motherboard sending 12.5v as power the only other diference would be pwm signal. I'll double check next time I have my righ apart but I think its more of a way that the H100i controls pwm than anything else. Honestly I will not be recommending this unit to anyone.
