Hi guys,

As the title says, I just bought a new cooler (Cooler Master Hyper 212 EVO -). I've read reviews that it's very loud but does the job. It's actually very low and I've noticed it on speedfan, it runs at 2k RPM which is the max. I've managed to lower the speed to 65-75% ( it was 100%). I was wondering if there's a way that it wouldn't always stay on max speed. My mobo is: z77a-g45

Right now, it's at 75% with a game on and its CPU reach 49C.. Idle is under 40C.

Thank you

Get into the bios and set the CPU multiplier to auto or check the other parameters, which are not auto. If you can't find it, reset the bios by loading the standard bios parameters

What do you have your fan controls set to in.the BIOS? Its been a while since I ran the 212 with the factory fan but I dont remember the fan being thag loud.

You can always swap it out for a quieter fan? I run the Cougar fans on mine.

Intel 3470 i5.
Not not overclocked
Fan is plugged into the CPU fan connector if I'm not mistaken
Pretty sure all pins are in otherwise it wouldn't work, would it?

You appear to be using third-party software (Speedfan) to control your fan, and to be using some manually-set fixed settings. Instead you could use the automatic fan control system already built into your mobo. That system can adjust your CPU cooling fan constantly according to the actual temperature inside the CPU chip, so that it only speeds up when you work the system hard.

Post back here exactly what mobo you have. We can help you set up your system for that automatic control.

Hi,

My mobo model is msi z77a-g45. I'm at work right now so can't check out my bios. What should I do in the bios?

I suggest you do the following to get your mobo's automatic system to control the speed of your CPU cooling fan.
1. Stop using Speedfan. Maybe un-install it if it appears to interfere.
2. Check your mobo manual on p. 1-25. The labels it uses for the CPU_FAN header strongly say it is a true 4-pin fan system operating in PWM Mode. Your Cooler Master system has a true 4-pin fan, so this should work just fine.
3. See manual p. 2-7 under Hardware Monitor in BIOS Setup. Go there and see what settings are available to you. Look for an option to use "Automatic" control or "Standard", something like that. Set that, then remember to SAVE and EXIT. This will reboot your system. Now observe your CPU cooing fan;s performance. At idle it should run slowly and quietly, but speed up as you do more work or start playing hard games. As you change what you do, the fan shold change its speed.

Will definitely try that after work. Just wondering what software should I use to monitor the temps if I uninstall speed fan?

That's a very good point. From my reading of the mobo manual, there is no utility for this included with the mobo CD. So, Speedfan is probably the tool to use. Keep it in place and make the BIOS Setup changes I recommended. If the fan seems to be changing speeds in response to load, start up Speedfan and just use it to observe temps and speeds. Don't use it to actually set any fan speeds, and maybe it will work with mobo control but allow Speedfan to show you the results without interfering.

Perfect thanks for the tips, I'll update later on, I guess when opening speed fan I have to uncheck the option "Automatic control fan"? Something like that

I'm in my bios right now, I have CPU smart fan target that's set to disable.
Sys control fan 1 control that's on auto
Sys control fan 2 control that's on auto as well

Problem solved, I changed the connector to the fan 1 and it`s on auto right now. Right is around 1.4k instead of 2k and I barely hear something. Thanks everyone

To get your mobo to control your CPU cooling fan automatically, you MUST plug that fan into the CPU_FAN header, then set its CPU Smart Fan Target (manual, p. 2-7) to Enabled.

You really ought to do it that way. If I understand your last post, you have connected the CPU cooling fan to the SYS_FAN1 header because it IS set to Enable the automatic control. There are three special functions carried out by the CPU_FAN header that are not available on others and are important:
(a) Control of the CPU_FAN header's fan is guided by a temperature sensor INSIDE the CPU chip which is what you need for cooling that chip. The SYS_FAN headers are guided by a different temp sensor on the MOBO.
(b) The system will display the speed of that fan according to where it is plugged in. So if you leave the CPU cooler plugged into the SYS_FAN1 header, it will show up as the SYS_FAN 1 speed, which it is not. Meanwhile, your CPU fan speed seems to be unknown entirely. The result is that failure monitoring is wrong. If that fan ever fails, it will suddenly tell you that a case ventilation fan has failed, which may not be cause for alarm. But in truth, the CPU cooling will have failed, and that requires IMMEDIATE action.
(c) On a similar note, SOME mobo's (I don't know about this one) have a special failure action for the CPU fan only. If the CPU fan fails (only can be detected if it is connected there and Enabled), the mobo may not wait for the internal temperature of the CPU chip to skyrocket. It can just shut down the whole system within a very short time and with a brief warning message to be sure the CPU does not get damaged by excessive temperature. This protection cannot work if the actual CPU fan is NOT connected to the CPU_FAN header.

Hi,

Thanks for the head up, although the is the CPU Smart fan target in the bios doesn't seem to have an option to enable only, it had options going from 30C to 70C, if I recall correctly, I'll check that out after work.

Above the table of targets to choose are some rectangles. The one off to the right seems highlighted, but i don't know what it says. But at top center is one labelled "Standard Mode". THAT may be the label for using the "normal" automatic fan control mode. Is it really a FAN control option, and not for something else? I can't tell because I can't read the other rectangles.

I can't restart my PC right now but this is similar to what I have taken from google SS( French though). https://www.google.ca/search?q=msi+z77a-g45+g45+cpu+smart+fan+target&client=ms-android-bell-ca&prmd=sivn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiGnvaDur_MAhXMlIMKHQAJCOMQ_AUIBygB&biw=360&bih=559#imgrc=2zZrOnZZ6uktvM%3A

This is a note from the bios, apparently.

Hardware Monitor
Press <Enter> to enter the sub-menu.
CPU Smart Fan Target
Controls CPU fan speed automatically depending on the current temperature and
to keep it with a specific range. If the current CPU temperature reaches the target
value, the smart fan function will be activated.
SYS Fan1/ Fan2 Control
These items allow users to select how percentage of speed for the SYSFAN1.
CPU/ System Temperature, CPU FAN/ SYS FAN 1/ SYS FAN2 Speed
These items show the current status of all of the monitored hardware devices/ components
such as CPU temperature/ system temperature and the few fans’ speeds.

So I have to choose a temperature until the fan start spinning fast?

From those images on Google, if that's what is on YOUR screen, the three rectangles DO appear to be options for setting the the fan control strategy. In more common terms, they are:
"Eco Mode" = run the fan slowly to save power and reduce noise, but that also means reduced and fixed cooling.
"Standard Mode" = normal operation with the mobo adjusting the fan speed constantly through a full range as the heat and workload change. THIS is the correct setting for you, probably.
"OC Centre II Mode" is for overclocking that requires high cooling, and VERY likely means that the fan will run at a fixed high speed.

The information under the "CPU Smart Fan Target" is confusing and wrong in some respects, I think. I know of NO automatic fan control system that merely shuts the fan off until the "target"is reached, and then turns it on full. The "Target" normally is the proper temperature for the CPU (internally) to be running. If it is at that temperature, the fan will be running at some medium speed. If it gets a little hotter the fan will speed up; if it gets even hotter, the fan will speed up more. If it cools down, the fan will slow down.

You should NOT have to set the temperature target for your system. Most mobos will recognize the CPU type and use its own pre-programed settings for the target IF you let it do so by selecting the "Standard Mode". Try that mode and check: (a) is the fan speed chaning as workload does?, and (b) does the indicated internal CPU temperature stay within a reasonable range for your CPU? For that last question, you'll have to search the web a bit for typical operating temps of YOUR particular CPU type (each is different).

I managed to put back to standard mode in the Bios, never noticed it was on OC genie mode, I'll put back the wire to the CPU fan and give some update how it works out.

Odd. MAYBE you changed that setting in BIOS without realizing it sometime. Or MAYBE your mobo did it for you as a default setting. Anyway, that does explain why your CPU_FAN header was set to the Overclocked high-cooling setting, and thus your fan was running fast and loud.

So, if the CPU remains set to Overclocked it will run hot and will NEED high cooling. So MAYBE that is why your fan still has not slowed down, even though it is set to normal automatic control strategy. If you turn off the Overclock, maybe it will cool doen and the fan will slow down. Then you can decide whether that makes your machine seem too slow.
