    Default Cooling question

    I am using the AsRock B87M motherboard, CaseIs a Xion 560 an R7 660x. I am limited to the number of fans the I can connect(4 -5 if I us the second CPU).

    I will be connecting 5 - 80mm Fans and a 120mm (front) facing in, 4 of the 80mmfans are on the side. A CFM recommendation would be helpful here?
    2 - 120mm fans(top/back) facing out. Power has its own intake. I would like tokeep noise down but cooling is my priority.
    I would like for the fans to be controlled by mobo. If mobo will not controlall the fans, is there a controller recommendation? How many fans to one pinsafely?
    <o:p></o:p>

    <o:p> </o:p>
    Would the Sunbeam PL-RS-PCI Smart PCIRheosmart Fan Controller be an option?<o:p></o:p>

    I've had excellent results with several different Arctic Cooling PWM fans including 80mm and 92mm models.
    My HAF XB case has two 80mm fans installed as air intake fans in the lower case compartment.
    The fans are very quiet below 1600 - 1800 rpm and are not objectionable at 2000 rpm.

    ARCTIC F8 PWM Fluid Dynamic Bearing 80mm Case Fan
    • model #: AFACO-080P0-GBA01
    • size: 80mm
    • speed: 850-2000 RPM PWM
    • air flow & noise: 31 CFM @ 22dBA
    • Current / Voltage: 0.14 A /12 V
    • Power Consumption: 1.68 watts
    • Patented PWM Sharing Technology
    • Fluid dynamic bearing
    • 6-year limited warranty

    It's generally recommended that the maximum safe load on each fan header should not be more than 1 amp or 12 watts.
    If needed, you should easily be able to connect four of these 80mm fans to one fan header.

    Many 80mm case fans provide about 20 - 25 CFM maximum air flow and the much higher powered 80mm fans will be much louder.

    ARCTIC F8 PWM CO | 80mm PWM Case Fan with Dual Ball Bearing | PWM | PC fan | quiet | silent -- Arctic product web page
    ARCTIC F8 PWM Case Fan - Newegg.com

    Read the user reviews at Newegg and Amazon.

    Some (many?) fan controllers do not offer a wide range of fan speed adjustments.
    Your motherboard might let you set up a custom fan profile for more than one fan header and this might work well for you.
    It might not be easy to find fans and a multi-channel fan controller that work well together.
    If you need a controller, don't buy a cheap model, buy a mid-priced model.

    Read the controller's user reviews carefully.




    Don't buy one of the "open cage" 80mm fans as they usually only work as exhaust fans.

    I assume you mean a ASR B85M board?

    To confirm, this is the Xion case here: Newegg.com - XION XON-560 mATX/ ITX Meshed Mini Tower Case, USB 3.0, Black/Blue LED

    I assume it is, since you mention the four 80mm side fans.

    I'll provide a differing opinion about your fan plans, and the design of that case.

    I'll tell you up front, I hate "small" fans, and to me anything less than 120mm is a small fan. I don't like them for two main reasons:

    They move very little air compared to larger (120mm) fans, so must run at high speed to compensate, but never do.

    Since they operate at high speeds, they are noisy, more so than larger fans, moving more air at lower speeds. Some of the most annoying fans I've "heard" are whiny, 60mm and smaller toy fans (IMO), and 80mm fans are the smallest size that I believe have any potential use for PC case cooling.

    Four 80mm fans of almost any kind, that are actually moving some air, will be very noisy, personally I could not stand it. Also, any fans mounted directly to a mesh grill like your case has, will compromise the air flow by... ~50%, even though the mesh is rather coarse on your case.

    Next, CFM ratings of fans (as well as noise specs) are virtually worthless IMO. There are no standards used for CFM and noise ratings of fans, so a manufacture can test any way they please, with any equipment. It is impossible to verify fan specs, since the testing procedure and equipment is unknown in most cases, and given different procedures and equipment, test results will never match the specs. The few good fan reviews I've seen (X-bit Labs) all show noise (in particular) and CFM ratings to be very different than the test results. Meaning more noise, and lower CFM. So, IMO comparing specs of fans made by different manufactures is a waste of time. The only way to know how a fan performs is to try it, and my box of reject fans is large.

    Back to your case, it comes with two 120mm fans, and another 120mm fan can be mounted as an exhaust on the top of the case. Fans provided with cases tend to be quiet and low air flow, which go hand in hand. Given your CM 212, you can orient it so its exhaust is pulled out of the case from the top or rear, with another fan mounted on the top of course.

    Since you are pretty much set on using 80mm fans, a few I've had some experience with. The Cooler Master Blade Master is relatively decent, but is a four pin PWM controlled fan. One of your chassis fan headers is a four pin PWM header, so these fans could be used with it, and an appropriate splitter cable.

    In my reject box is the ENERMAX UC-8EB fan. Silent, yes, but so is a fan with no voltage applied to it. Ultra-low air flow, I was shocked, and that is holding the fan in my hand with nothing restricting the airflow. But you can find 600 reviews and a four star rating at Newegg for this fan. So what do I know??

    Default Re: Cooling question

    What is the brand and model number of your cpu cooling setup in your B8xM system?
    The CM Hyper 212 EVO cpu cooler is about 160mm tall (from the top of the cpu) and the width of your Xion case is only 7.3 inches (~185mm).
    It is unlikely that the EVO cooler would fit in your case, even with no 25mm thick fans installed on the side panel.

    From WWW.XIONUSA.COM:
    • Supreme cooling capacity up to 7xFans ( 3x120mm & 4x80mm, or 3x120mm & 1x200/220mm) fans

    A single 200mm cooling fan will be much quieter than 4 80mm cooling fans and many 200 mm models have 110 - 135 CFM air flow at about 700 - 900 rpm. The problem will be finding an easy to mount 200mm fan that does not require a custom mounting setup because the fan's mounting tabs do not conform to an industry standard setup. Many or most of these fans are designed to fit specific computer cases only.

    Newegg.com - Computer Hardware, Fans & PC Cooling, Case Fans, 200mm, 220mm is a list of 200/220 fans sorted by highest customer ratings. Several times I've seen the Cooler Master MegaFlow 200 fan with a discount and mail in rebate with a net cost from $8 - $13. Keep in mind that this fan is 30mm thick, not 25mm. I'll measure my MegaFlow 200 fan tomorrow and post the fan's mounting tab dimensions.

    I found this MegaFLow 200 web picture and I'll confirm the dimensions tomorrow.

    **edit** Ignore these measurements, my measurements in the next post are correct. I'm right and the whole world is wrong.

    I agree that the 200mm fan option is better than multi-80mm fans. For both noise and air movement.

    I will say do NOT bother with any 200mm fan that is less than 25 - 30mm thick. There are several out there, like the one that came with my Corsair 500R case. It is worthless for cooling, and is in my junk fan box. One 140mm fan blows it away, literally.

    Standard 80mm case fan dimensions.




    My HAF XB computer case allows two 80mm fans to be installed on the lower rear panel and the distance between the adjacent fan mounting screws is about 20mm. This means that there is 163mm between the leftmost and rightmost fan mounting screws where 71.5 + 20 + 71.5 equals 163mm. This information is laying the foundation for the good stuff coming up.




    I don't know what the overall corner distances are with your side panel, but my best SWAG is that there is close to 153mm between each of the corner mounts and this works out to a 6 inch by 6 inch setup that might just work with the Cooler Master MegaFlow 200 fan or a different fan that has the same 153mm by 153mm mounting tab setup. Note: there are two closely spaced fan mounting holes in the outer four corners of your side panel grill.

    It looks like 153mm or 6 inches is the magic number for a reasonably trouble free 200mm fan installation based on the "correct" diagram that I previously posted.

    Do ya feel lucky?
