Need To Know What 4 PIN FAN CONTROLLER To Get Or If I Need One.

I have a total of 7 fans in my case. 2- 140mm Cougar CF-V14HP Fans. 3- 120mm stock fans that came with my Corair 500R. and 2 140MM fans from my last Chassis.

Now.. Strangely..All of my fans EXEPT the really nice Cougar 140mm fans connect and are easily controlled through my ASUS MOBO Software. Don't get me wrong, The Cougars Partially Register in the BIOS. Meaning they show up and the RPM is read perfectly. But when I try to tune them manually (or even with the different auto settings) my BIOS freezes and I have to hard-restart my computer. The Cougars also Partially Register in my "ASUS ThermalRadar" that is part of the ASUS Z97 Mark 1 MOBO.

But, Again, When I go to tune them the graph reads "N/A" like there isn't any fans plugged in to that/those channels at all. But when you look at the RPM monitor it shows them sitting around 800 RPM.. very strange.

SO almost all of my fans are 4 pin. Soon, once I replace the stock 2 front fans they all will be 4 Pin. What fan controller would you guys recommend? I have my 2 Cougars plugged straight into the PSU in order to get the full cooling potential for my 290X crossfire configuration. But when I'm not gaming and am trying to sleep, I can hear them :/.

IF ANYONE has a solution to the Cougar connectivity issue then by all means, share that with me so i don't have to get a fan controller... if there isn't a solution.. Then what fan controller would you Enthusiasts out there recommend.

    This may be a different issue. some fans are voltage-regulated and others are regulated through pulse modulation. I'm wondering if you're running afoul of this issue? Not sure how to tell you to check, but I believe some fan controllers and motherboards have options on how to set this?

    well. I dont know if this is what you're talking about. But in the BIOS, you can control the fan based on temperature (just like the ASUS ThermalRadar). but the BIOS controller has an additional option when you are in the graph section of a single fan. Up in the top right hand corner you can choose 1 of 2 options. PWM and....Something Else. I tried each one of the settings and my computer would still freeze up if i tried the manually set the Fan speeds based on temps.

    now i would just set my fans in the ASUS Thermal Radar software but when i go to the channel where a Cougar fan is connected, it reads N/A as if there is no fan plugged in. but when you look at the RPM monitor, it reads just fine.
  3. Yea, it's that "Something Else" I'm talking about. I know it exists, but I don't use it. I have Cougar Vortex fans, they work fine and I have them on auto. From time to time when I stress my PC I hear them spin up a little.

    But I have an Asus motherboard, so I can't help you much further. Sorry.
  4. i figured it out. i do not need a fan controller. my ASUS z97 Sabertooth mark 1 fan Expert software works perfectly. no need for the controller.
  5. Wow, long time.... Glad you finally figured it out. :)
