Hello. I just ordered some new fans for my h100i because the stock ones were awful, and im not 100% shure how to install them. Should I plug the new ones where the stock ones were?
 
Solution
Yes, just plug into the same place as before. However, if you picked a slower fan to cut the noise down from the H100is 60+ dbA to something more bearable you will see a big drop in performance.

As I recall, the 100i started out with non PWN fans and later switched to PWM so make sure you purchase with same kind.

The H100i's fans are "awful" cause those 2700 rpm fans is what makes it thermally edge out air coolers which spin at 1200 rpm to 1500 rpm. Put the same 1200 - 1500 rpm fans on a H100i as on a typical top end air cooler and the air cooler will have better thermal performance.

They spin at up to 2700 rpm; that's what allows the unit to accomplish the thermal performance you read about in the reviews. Turn the fan speeds...


Hey There! Yes, you'll need to be careful though...if the new fan's wattage requirement is too high...you'll blow the little port for a 4 pin fan. Usually you'd be given a free 4 pin power adapter. I have two 5200 RPM Exhaust Fans on my tower and they require 46.7W. An adapter came with them so I wouldn't blow the sockets.

Have Fun!

Turn the fan speeds down, and it will get quieter, but the thermal performance also drops. The sources below list thermal performance from 600 rpm to 2200 rpm.... in general custom water loops generally have fans running at that latter end speed cause it's just way too noisy.

Personally, I don't use anything faster than 1200 rpm and I run them using MoBo speed control between 325 and 850 rpm......6 fans on a 420 rad, 4 fans on a 280 rad and 5 case fans.

I got 2x of these Noctua NF-F12 PWM 120mm Case Fans for my h100i. Let me get it right, I plug them where the old h100i were ? And after installation what program should I use for the fan speed control ? Will corsair link still work ? Its good for something ?
 
Dunno about link but most enthusiast / gaming MoBos come with a fan control speed utility (Asus FanXpert3 is best) and just about every MoBo provides speed control via BIOS.

Expect to lose about 60% of the unit's cooling ability with the slower fans so if you have overclocked, keep an eye on things.

Now that the unit is mounted, we will want to plug in power cables for both of the fans and the pump. The H100i has an integrated 4-fan hub which is where you will want to plug in your H100i fans. You will find two ports on top of the cooling unit, where you can plug in the included fan power adapter cables. Each adapter will support two fans, and by plugging the fans directly into the fan power adapter cable and into the cooling unit, you will be able to monitor and control the H100i fans through the Corsair Link V2 software.
