[SOLVED] How many fans are possible in this build?

Jun 15, 2019
Hi, I'm looking to fit more fans to my build, right now I currently have two, one attached to the back and one at the front. My motherboard temps are reaching pretty high for a brand new motherboard so I'm hoping this will calm it down even if just a little.

Here's my build
Seasonic SSR-650FX FOCUS Plus Gold 650W (80+Gold, ATX 12V) PSU/Power Supply
ASUS M5A78L-M PLUS/USB3 Motherboard - (Black) (AM3+ FX 760G, 6 x SATA 3Gb/s port(
Asus DUAL-GTX1060-O3G NVIDIA GeForce OC Edition 3 GB GDDR5 192 Bit Memory PCI Express 3 Graphics Card
Corsair Carbide Series 275R Mid-Tower ATX Case

I don't have anymore space to attach any fans to my motherboard so I was wondering if there are anymore connections on this PSU that will allow for a fan to connect to it.

Thanks in advance


All you NEED is two front intake, a rear exhaust and a top rear exhaust. Anything beyond that such as top middle or top front fans, will simply steal air from the CPU cooler.

What are you using to monitor your temps that you know the motherboard is getting too hot? WHICH of the motherboard thermal sensors are you referring to?

If you are not using HWinfo to read the motherboard thermal sensors, and are using something like Speccy, HWmonitor, Open hardware monitor or another monitoring program, then there's a good chance you're getting faulty readings or that they are reading the WRONG thermal sensor and mislabeling it. It's common.

Also, for FX series CPUs, you can't measure "CPU temp" like you would for other CPUs, so if you're doing that, you're doing it wrong. FX series CPUs need to be monitored for thermal margin (Distance to TJmax) using AMD overdrive or Core Temp (With the "Show distance to TJmax" option enabled in the advanced settings) otherwise your readings are simply bogus.

Here is an an depth explanation of how to understand AMD thermal margins.

Monitoring software

HWmonitor, Open hardware monitor, Realtemp, Speccy, Speedfan, Windows utilities, CPU-Z, NZXT CAM and most of the bundled motherboard utilities are often not the best choice as they are not always accurate. Some are actually grossly inaccurate, especially with certain chipsets or specific sensors that for whatever reason they tend to not like or work well with.

I've found HWinfo or CoreTemp to be the MOST accurate with the broadest range of chipsets and sensors. They are also almost religiously kept up to date.

CoreTemp is great for just CPU thermals including core temps or distance to TJmax on older AMD platforms.

HWinfo is great for pretty much EVERYTHING, including CPU thermals, core loads, core temps, package temps, GPU sensors, HDD and SSD sensors, motherboard chipset and VRM sensor, all of it. When starting HWinfo after installation, always check the box next to "sensors only" and de-select the box next to "summary".

Run HWinfo and look at system voltages and other sensor readings.

Monitoring temperatures, core speeds, voltages, clock ratios and other reported sensor data can often help to pick out an issue right off the bat. HWinfo is a good way to get that data and in my experience tends to be more accurate than some of the other utilities available. CPU-Z, GPU-Z and Core Temp all have their uses but HWinfo tends to have it all laid out in a more convenient fashion so you can usually see what one sensor is reporting while looking at another instead of having to flip through various tabs that have specific groupings, plus, it is extremely rare for HWinfo to not report the correct sensor values under the correct sensor listings, or misreport other information. Utilities like HWmonitor, Openhardware monitor and Speccy, tend to COMMONLY misreport sensor data, or not report it at all.

After installation, run the utility and when asked, choose "sensors only". The other window options have some use but in most cases everything you need will be located in the sensors window. If you're taking screenshots to post for troubleshooting, it will most likely require taking three screenshots and scrolling down the sensors window between screenshots in order to capture them all.

It is most helpful if you can take a series of HWinfo screenshots at idle, after a cold boot to the desktop. Open HWinfo and wait for all of the Windows startup processes to complete. Usually about four or five minutes should be plenty. Take screenshots of all the HWinfo sensors.

Next, run something demanding like Prime95 version 26.6 or Heaven benchmark. Take another set of screenshots while either of those is running so we can see what the hardware is doing while under a load.

For temperature monitoring only, I feel Core Temp is the most accurate and also offers a quick visual reference for core speed, load and CPU voltage:
