Cpu liquid cooler Fan Performance

[projectx]

Noob Here

I want to change the Fan for my Corsair H110i GTX but i am not sure about the performance if it will still be the same.
Please Help. is there any difference about the performance in 3, 4, 5 pins fan. Thank you in advance

I have a Corsair H100i V2, and I bought their Sp120 LED fans and put those on to match my case aesthetics rather than their stock fans. Works perfectly fine. Keeps my 6700k quite cool and they're very quiet. The only complaint I would have about my SP120's is that they consume more energy due to their LED's and my motherboard CPU header has to run those 2 fans AND a pump so it doesn't run at 100% (fans top out at 1450 instead of their rated 1650)

As far as performance goes, that's entirely based upon what fans you use. If you buy crappy, non-optimized fans, it will not perform well. if you buy excellent fans, it will preform well.

3 Pin = Voltage Power Regulation. You can control the fan speeds by giving giving the header anywhere from 7V-12V and they run at that speed.

4 Pin = PWM (Pulse Wave Modulation) a more sophisticated way of controlling your fan speed, in most cases you would want this for less than 7V operation speeds (sub 60%ish).

5 pin = something I've never heard of, so I cant comment on this.

3 pins work with 4 pin connectors, 4 pins work with 3 pin connectors. Your fan will simply utilize the lowest number of pins that either it has or the motherboard has.

Did you have any particular fans in mind? I could tell you if they were desirable for your H110i GTX if you would like.

Hi Zyndo, im planning to buy the SP120 140mm to match with my case.
But the problem is the stock fans are connected directly to sata going to PSU.
So if i change the 2 fans, can i just plug the fans directly to the Motherboard insted, 

so i can control the fan Speed..

There should be no reason that if you buy SP140's  that they would be incompatible with your H110i. I was not aware that the H110i powers their fans off the PSU.. but if you buy other fans, mount them to your rad, and plug them into your motherboard (as you would with any other case fan) they should operate and cool your radiator just fine (assuming they are Static Pressure Optimized).

You would still need to account for whatever is powering the pump in your H110i though. if thats the SATA cable, keep that connected so your pump operates, if it has a 4pin connector doing that, make sure its still connected to a CPU OPT, CPU, or designated Water Pump header on your mobo. If your H110i isnt pumping its liquid around, you're gonna have a bad time

I think the Sata power cable is the one giving the pump power to operate..

 

can you help me..
