Overclocked at 3570k but the fan is very noisy.
Overclocked at 3570k but the fan is very noisy.
Hey there, I've only experimented with overclocking a few times using my 212 evo before, and it was always quite loud. I thought that was because the default fan was being used. Recently, I purchased a Noctua NF-f12 fan, which is very quiet under normal conditions. I tried overclocking again with this new fan at 4.2 GHZ and 1.15V, but it became extremely noisy.
Without overclocking and during regular use, my fan operates at just 23% of its maximum speed (which is the minimum due to my motherboard's Smart hardware control). When playing CPU-heavy games like CSGO, it uses around 40-48% of its capacity. However, when overclocked to the mentioned settings, the Noctua increases to 40-52% during idle, and even more at 80%+ while gaming. This seems unusual—should I consider replacing it with another cooler, like an AIO, since my case is tall and might not fit other air coolers? Or could switching to a different CPU cooler make a noticeable difference? I'm eager to overclock but also want a quiet PC. I'm willing to spend up to $120-140 CAD on a new cooler if needed. Any advice would be greatly appreciated. Thanks.
Hey there!
I just noticed something that might be affecting my whole PC in terms of temperature and noise. My PSU has been making a lot of noise lately, and I didn’t really notice it before because I always had my headset on. It seems like the fan was facing up instead of at the bottom of the case where there’s a filter. This probably means more hot air is entering, forcing the fans to work harder and creating more noise. I’m not sure if this will make a difference, but it might help.
The basic idea is to check and optimize what you have before switching to something new, since the problem wasn’t the start.
Increasing the speed means generating more warmth, which requires a quicker fan to remove it. Regardless of the fan model or cooling solution used. The same applies even when overclocking isn't involved. Higher demands (like gaming) lead to increased heat and consequently a faster fan.
Hey there,
Just wanted to confirm that this level of change was anticipated given that overclocking during idle is similar to running at full CPU usage without optimization.
Would an AIO such as the H110i V2 really improve the sound with two Nf-nf12s added?
Liquid coolers could potentially make a noticeable difference. More moving components involved—fan, pump, and liquid flow.
I recently switched from an old CM Hyper 212+ to a Cryorig A80. It was slightly louder both at idle and under load, though it stayed cooler across all conditions.
Additionally, the condition of the case and fan filters plays a big role. A dirty filter forces the fan to spin faster to move the same airflow, which often results in quieter operation once cleaned.

Fans, pump, and liquid all contribute to the noise level.

I noticed that some air coolers looked decent but didn’t fit well due to my RAM setup. This case is newer, so most filters are clean enough, but I’ll give them a quick cleaning soon—every bit helps.
In short, it seems unlikely I’d have both a quiet PC and an overclocked CPU at the same time. It’s probably one or the other.
I’m thinking about upgrading to a 6700k, but I’m holding off since a new motherboard and RAM would be needed, and my 3570k still has some life left.
I just noticed something affecting both the temperature and quietness of my PC. My PSU has been making a lot of noise lately, which has been a problem for a while. I didn’t really notice it before because I always had my headset on. It seems the fan was facing up instead of at the bottom where there’s a filter. This must be causing the fans to work harder and produce more noise. I’m not sure what caused this, but it might help if it changes things.

Hey there,
Just noticed something that might be affecting my whole PC in terms of temperature and noise level. My PSU has been making a lot of noise lately, which has been bothersome. I didn’t really notice it before because I always had my headset on. It seems the fan was facing up instead of at the bottom of the case where there’s a filter. So now I’m getting hot air in, forcing the fans to work harder and making more noise. Maybe this will help... Not sure how I managed that.
That should probably make a difference.
General advice – always check and optimize what you have before switching to something new, since the problem wasn’t there initially.
I just flipped it and cleaned the front filter. It’s actually much quieter now (not noisy). But I can’t really hear the airflow from the PSU anymore; it sounds like it’s struggling, like an old fan squealing. I saw some videos suggesting adding lubricant to the fan blades, so maybe I’ll try that too. Thanks for the help!
