Best Way to Setup Automatic Fan Controls?

Hi All,

So I finally built my first gaming rig (specs are in my sig).

I have been using the 3-speed fan controller on my Phantom and it's pretty nice. However, the software to control the H100i is terrible. Half the time it doesn't even work.

So I'm trying to figure out the best way to setup my fans.

Should I just connect all of the fans to my 3-speed controller? Should I set it up automatically (I'm pretty sure it's possible with the Sabertooth but I'm not sure how to go about it)? If the automatic control is a good idea, how should I do it? Through the bios or a separate program?

I'd really appreciate some advice from someone with a H100i and a similar mobo.

I guess I could hook em all up to the control and blast it when I game. I don't really care about noise because I always wear headphones.


EDIT: I should note that I'm using a custom fan profile in "EVGA Precision" for my GPU. Not sure if that matters...

I have an H100i as well but I've had no issues controlling the fans with the software. For gaming and browsing I leave each fan set to "Quiet Mode" for benchmarking/stress testing I set it to "Balanced Mode" and when I want to drown out my wife I set it to "Performance Mode". It works great and scales perfectly depending on the temperature of the water passing through the block. Have you tried the firmware update yet?

I would get a PWM Splitter(and cut the speed sense on one of the two connectors if needed) and use the bios to control fans. I find the bios to be best and it has the ability to crank it up if things get too hot.

I put the H80i fans on bios control(but the H80i control WAS working. Best part was setting stick after reset even if you disconnect the link cable. I just like the bios control better) and set a MAX speed of 1500rpm and even under load it did not need more than 1200 or so. This makes it much more quiet, but does not remove the kind of grind/rattle of the fans.

Since board control got so good, I always recommend using it.

Hi,

Yea when the corsair software works, it's pretty nice. I did update it after I finished the build. I think it gets screwy after the computer falls asleep and wakes up. I'd like to use it, hopefully they fix it.

your sabertooth has asus alsuite with fan xpert II software if you've got 3 pin fans then just change the setting in fan control in bios cpu Q-fan control to advanced mode (even if your cpu fans are pwm you need to do this if the chassis fans are 3 pin) when you load into windows you need to click autotune in fan xpert it takes 4 or 5 mins to establish all the speeds of your fans and after that you can select preset profiles or make custom profiles for different speeds at different temperatures, its very effective and intuitive to use

The Corsair H100i has an independent setup for fan control:
http://www.corsair.com/us/hydro-series-h100i-extreme-performance-liquid-cpu-cooler.html

It MAY be possible to bypass all that if he's having problems but I can't tell from the pictures.

*I believe the Asus Sabertooth ONLY has control for PWM fans, not Voltage. If the fans have 4-pin connectors they are probably PWM.

Questions:
1. What EXACTLY is the problem with the Corsair software?

2. Did you update the FIRMWARE for your H100i?

3. Does your Corsair software allow for AUTO control (a ramp) that varies the fan speed by temperature?

No you just change a setting in bios for dc mode fan control and it will control 4 pin and 3 pin fans, I stand by my opinion of fan xpert been the best option of automatic fan control, its easy to bypass just plug all his fans directly on the motherboard fan connectors

Edit: ok the software is called thermal radar 2 on the sabertooth (looks the same as fan xpert just some different temperature monitoring) on chapter 3 page 3-40 it explains about setting cpu Q-fan control to advanced mode for dc fan control (3 pin fans) you need to set this even if your cpu fans are pwm and your chassis fans are 3 pin as you will be able to control both types under this setting

I made some changes, I'll post tomorrow and see what the outcome is. I like the looks of the thermal radar software. When my new fans get in, I'm going to use that instead.

I figured out that the corsair software would become unresponsive after waking up. I updated the two chipset drivers for my sabertooth in hopes it would resolve the issue.

You may be right:
1. I don't own the Corsair solution and couldn't tell from the website how the fans connected. If they can easily be plugged into the motherboard and speed control works that's the best way to go since there appear to be issues with the Corsair setup.

2. The Z77 Sabertooth has only PWM fan control for the CPU. There is no DC-mode or whatever for 3-pin/4-pin fans.

So hopefully your solution works well for his Z87.
