My air cooling problem.
3 hours ago, l3igwill said:My ambient room temperature is about 20C and I was thinking that using the same voltage if not lower then what others are I shouldn't be getting as high of temperatures as I am. Sorry I left out some important details on the original post without thinking about it. I was aiming for 4.5 but when I increase the voltage my temperature skyrockets. I have seen people reach 1.55V @4.5 and have decent temperatures on the H100, and I believed that my NH-D14 had similar dissipation.
That is why I am here to learn, Thank you for the feedback I just thought that since I had lower voltages or the same voltages it would produce the same amount of heat. I was just confused because I believed that my air cooler should have been able to dissipate more then it is.
Ok, sorry for being bit harsh. Here's few things more in depth about cooling and OC.
First about silicon lottery and why you can't just use same settings on same CPU model. Every OC guide you read or watch tells to test your own settings, not to copy them from another person or from guide. Silicon lottery is one of main reasons why not. It means that there won't be two identical CPUs. Reviewers and Youtubers are known of getting best of the bunch as they are ones doing most of hidden advertising for CPU manufacturers. So their stuff will run faster with lower voltage and lower temps. You can't also rely on another normal users settings and results. But there's more things than just silicon lottery in action.
H100/i and D14/15 are pretty much same when it comes to running on stock speeds and settings. And when using same room temp and CPU. What temps you get when running stress test on stock settings gives you indication of how much headroom you have before hitting 85C+ danger zone under stress. You may see in reviews that they are running also OC, usually mild and extreme. This is one good review with those charts https://www.guru3d.com/articles_pages/noctua_nh_d15_review,11.html
H100/i (or H110) and D14/15 are close when on stock, but you can see about 5C difference when running with OC. My opinion is that if you aim for higher OC, lets say over the average, you will need to go for water. Air is better if you are running average OC and want to keep things rather quiet.
So things that can be and are different when comparing results:
- Silicon lottery aka performance of CPU.
- Cooler used
- Ambient/room temp
- Install process aka how much and what thermal paste (can have 1-3C difference if applied correctly)
- Stress test used
- Fan speed and amount of fans (more, bigger and faster fans = lower temps)
I'm not big fan of Prime95 for it being ancient when it comes to stress tests. It should be fine with that CPU though. I'm also not familiar with OC on Extreme edition CPUs, so I don't know where safe voltage limit goes. General thing is that higher you run voltage, more heat it will generate. To give example from my own 4770K (U14S dual fan). With stock settings (voltage hits 1.19V) I got 68C max temp using OCCT for 15mins. My slight overclock of 4.0GHz (1.15V) has 72C max temp. Highest I've had it is 4.2GHz (1.3V) and that had temps well over 84C (max cut temp is 87C).
