It has several sensors around the board that monitor surface temps, and I use some of them to control my fans (mainly CPU, RAM, and PCIe sensors). Also make sure your rear fan (or whichever is closest) doesn't rob air from your H100. This is why I actually use my rear fan as an intake, to supply the rad with cool air from outside the case as well. The air exiting the system from the top isn't that warm, even at heavy load.
Any of you using the stock fans with your H100i, or similar Corsair cooler? I would strongly recommend changing them to aftermarket fans, preferably PWM (for compatibility). A few weeks ago one of the SP120 high performance PWM fans that I use on the H100i started to make a ticking noise. The noise would rise and fall with the changing RPMS and was very annoying and distracting. It wasn't the firmware (as others suggested in another thread) because I hook my fans directly to the MB headers and control them with Fan Expert/Thermal Radar. It only effected one fan but I had to RMA both because I had purchased them as a set.
Well I mounted the stock fans temporarily and I was amazed at the difference in sound. Although the stock fans look exactly like the SP120s (without the colorful ring) they are certainly different on the inside. I had been lead to believe that they would be nearly the same, and some people even claimed that they may be better than most aftermarket models. The stock fans make a much higher pitched noise than the SP120s and they are audible at much lower rpms. At idle I can't hear the 120s (900rpms), but the stock fans are clearly audible at the same curve. During CPU stress testing they sound like a jet engine, and were almost worse than the ticking noise the broken SP120 was making. The SP120s aren't perfect and they become audible as the load increases, but the sound is much lower pitched. As far as cooling is concerned they are nearly the same, but the stock fans need slightly higher rpms (or a more aggressive fan curve). So not only are they nosier, but they need to be set slightly higher to achieve the same cooling efficiency. Mounting the stock fans really made me appreciate and miss the SP120s. The replacements came in yesterday and my computer is back to being relatively quiet and cool.
I only brought this up because I saw some people post comments (on PC part picker) that the stock fans are basically the same as the Corsair SP series, and that is just false. I also know that some people have claimed that aftermarket fans won't work with some Corsair closed loop water coolers, but you can always hook the fans into your MB headers, or a fan controller and bypass the Corsair link. I know most of you here are most likely not using the stock fans and I am preaching to the choir. To those of you that haven't upgraded I recommend that you do...
Just a note on this too
Here's a bit more of comparison between the Stock and the SP120 (Quiet and Performance)
Sound Level 37.68 dBA
Speed 2700 RPM
SP120 PWM High Performance Edition
Sound Level 35 dBA
Speed 2350 RPM
SP120 PWM Quiet Edition
Sound Level 23 dBA
Speed 1450 RPM
It's not much difference between the Stock and Performance but its audibly different.
The stock are really loud! They do sound like a Jet engine lol
Speed wise though, the Stock have the highest max Speed of all 3.
