I'm can't diagnose this problem myself. Ever since installing my new motherboard and processor, the fan has been running exponentially faster.

SPECS: i7 7700k Kaby Lake, Gigabyte H270-Gaming 3, GeForce GTX970, Samsung SSD 850 EVO 250GB and my harddrive is specified as WDC WD10EZEX-00BN5A0

EDIT: Didn't mean to make this post under graphics cards. First post.

Ok, so, since it's not doing it all the time then perhaps it's simply the fan curve profile you have selected. Did you change it to silent?

If you did, and it didn't change, maybe the CPU fan is plugged into the wrong fan header? Should be plugged into the CPU_FAN header. (Just like that. CPU_FAN) Not CPU_OPT or any other fan header like SYS_FAN. There should be a printed designation right by the connector (Header) for each fan header on the board.

If all that is good and it's mounted correctly, plugged into the correct header AND the fan curve is set to silent or standard, preferably silent, then perhaps you simply need a different fan to mount on there. The Hyper 212 fan is rather loud to begin with.

You can easily put a...

Did you set the CPU fan profile in the BIOS? IF not, then you need to do so.


If you did, then you need to check your CPU temps. Might be that you didn't get the cooler mounted properly or one corner is not down fully, and the CPU fan is running high because there is actually a thermal issue. Another possibility is that you have the CPU fan improperly plugged in or plugged in to the wrong fan header.

EDIT: Also, the CPU temperature is around 60-69 degrees while playing recent games, and I can feel some heat. is that bad?
How do I do that? I have the Gigabyte BIOS due to the fact that I have a Gigabyte motherboard.

You need to press delete or whatever is required on your board model to enter the bios, starting as soon as you push the power button to turn on the system, and keep pressing repeatedly until you see that it is entering the bios.

Your motherboard manual can be downloaded here: http://www.gigabyte.us/Motherboard/GA-H270-Gaming-3-rev-10#support-manual


You can find the instructions non changing fan and cpu cooler fan settings in the bios section of the manual.

Alright, I found the fan settings. I'm not 100% sure about this though, so another question; Before I recently updated to an i7 and a new motherboard, with my i5 the Hyper 212's fan was basically silent. What would cause that kind of difference?

The bios settings. Default is probably either performance or standard, but it might default to full speed operation until the setting is configured. I'd set it to silent or standard. Also, before you do that it's probably a good idea to go into the bios and select the option for "optimal default" or "setup default" bios settings. Then set the fans or other options. Be sure to save settings before exiting bios.

Also, probably a higher TDP processor with the addition of hyperthreads in addition to the four cores. All i7's make more heat than same gen i5's.

Alright, thanks for all the tips. I'll set it to silent and see how it goes. My primary concern with that is the PC overheating, but i'll see. Was also thinking of buying a new fan besides the stock one but Cooler Master is out of stock of the mounting clips.

Silent doesn't mean slow. As the temps go up, so will the CPU cooler. At full load the fan will still be running at max speed, it will just be running at a lower speed at idle, AND the fan curve will keep the CPU cooler fan at a lower speed until you reach around 60 degrees or however it's configured. It's not going to cause the CPU to overheat. Do you really think Gigabyte would take that sort of chance with liability?

Sorry, i'm not super experienced with this, just trying to get my fan sound down. I'll see what happens. Unfortunately, can't put in a more silent fan due to lack of mounting clips being sold. I was just a little concerned because my GPU was warm to the touch and thought it was overheating.

I was under the impression we were talking about the CPU, not the GPU. If we ARE talking about the CPU, how/why would you be touching it? That doesn't tell you ANYTHING anyhow. The CPU or the GPU card surface temperatures have ZERO to do with the core temperatures. There is probably a 10-20°C difference if not more.

Core temps raise and lower nearly instantly. Exterior temperatures take long periods of time to raise and lower, but especially to lower. Regardless, exterior temps have little to do with core temps on any component.

Also, I never mentioned anything about a different or "more silent" fan. I simply said to change the settings in the bios to a different profile. Not sure where you got that from. If there is any part of this that you are not able to understand then you should get somebody involved, like a friend or family member, who is experienced and capable with computer hardware.

We are talking about the CPU. I am just trying to diagnose why my Cooler's fan is working so hard and why it still gets warm/hot in the computer. The comment about the "more silent fan" was referring to me replacing the Hyper 212 Evo stock fan with a new aftermarket fan (but I cannot, mounting clips are not in stock anywhere).

My mistake. I'm probably just going to edit fan settings on the BIOS. I don't think it should be running so fast I can hear it over game audio.

Honestly, I checked the bios and the mounting, and it seems fine. Weighing my options with just replacing the stock fan. Do you have any suggestions?

EDIT: Forgot to add this little tidbit. It's not constantly running full RPM, it's just ramping a lot and the noise is quite loud

You can easily put a different, much better fan on there without any trouble at all.

First, a different fan. I'd recommend THIS one which is probably the highest performing, quiet fan on the market. Or at least in the top two or three:
