Looking to lower CPU temps

Hey all. Yes it's another question about CPU temperatures.

I have a define r5 case with exhaust fan and one 140mm fan at the front.

Inside I have an Asus strix 1080ti oc that blasts out upto 69 degrees at max load.

I have a Corsair H60 with a push pull fan setup set into the top of the case that was applied to my 2600k with Grizzly paste in a cross pattern.

My CPU is set to 4.2ghz with 1.35 volts pushing through it via the oc genie feature on my OC z68 MOBO so could possibly go lower.

My temps reach 69 degrees on the CPU after a few hours gaming. Any suggestions guys as the fans can get a bit loud at this temp?

Thanks

Is it the CPU or GPU that's 69c? Or is that overall case temperature?

What are they individually?
Is it the CPU fan or the gpu fan making the most noise?

Both of them get to around 69c but the over all case temp is around 35c. The fan that I hear is the CPU one as the GPU fan is quiet as a mouse on the STRIX 1080ti.

Ive also edited my first post to be more specific.

Also the CPU fan profile might be a little enthusiastic, you may be able manually change the CPU fan settings to something a little less aggressive without incurring any meaningful rise in temps, for example if the fans set to go full tilt at too low a cpu temperature.

I have my fan curve set from 20% fan at 30c to 100% fan at 80c. This is with the MSI Control Centre which is a bit of a pain as it never remembers your settings so i have to set them on every reboot. I think im going to have a go with SpeenFan to resolve this issue.

Is your Corsair H60 seated on the cpu correct, and are the rad fines clear of dust?

I reseated the CPU last weekend when i got a new case the Fractal Design R5 silent. I cant remember the temps before but things seem a bit louder. I ensured that the thumb screws are 100% tight and that the rad was dust clear when i did this.

Yeh, you may be able to lower the voltage a little bit of your using a predefined overclocking setting, the presets can often be over generous with voltage.

Ill have to do this in the bios as again the control centre never remembers my settings :(.

My pump is also spinning at 3000rpm. Is this too low?

The ultimate aim here is to make the system a little quieter when gaming and currently when the fan is kicking out noise at 80% - 90% fan speed its a little annoying.

Thanks all for your advice, keep it coming :).

I would look to manually do your overclock such that you can lower the vcore and thus lower the heat output. If you need some help I might be able to remember how to OC on MSI 1155 boards but it might be better asking the google overlords.

I would appreciate that hugely. The advantage of OCing using Genie is that the RAM gets OCed as well so id need to do that manually which i have zero experience in.

I can manually OC GPUs and ive had some experience in the CPUs so it should be pretty easy.

The mother board i have is this - https://www.msi.com/Motherboard/Z68AGD80_G3.html#hero-overview
 
So basically if i switch off the genie mode, set XMP, up the multiplier and voltage all will be good? Are there any other settings i need to worry about?
 
OK so I have been able to set up some nice fan curves on speedfan so that's quietened things down considerably which is good. The only issue I am facing now is that all my voltages and multipliers for my CPU are grayed out in the click bios settings..... Confused

By click bios, do you mean the terrible windows software?

Lol no mate. Its actually the BIOS that you can use your mouse in. Ive sorted it now as all you need to do is use the + or - to set the voltage. Currently stable on 4.2Ghz at 1.33. Prime 95 is currently running so we will see how it gets on. The good thing is that ive used Speedfan to keep the noise down and the lower voltage is also helping with temps. Ill never use Genie 2 again. Thanks all for your help :)
 
OK so she didnt like 1.25 at all a crashed almost immediately. Ive pushed it up to 1.27 and running prime95 now. I havent touched the load line calibration....i dont know what that is.

Regarding the not remembering your fan settings every reboot, I saw that when I first messed with MSI Control Center, and it turned out to be because the BIOS settings would override the Control Center settings. I could get around it (if I remember correctly) by lowering the fan RPM in BIOS below what my Control Center RPM setting was. But eventually I just did the settings in the BIOS itself and scrapped Control Centre. HTH maybe.

In the end i just scrapped click bios and the control center and went for Speedfan. After setup i would never go back. Its not pretty but its brilliant

Load line calibration (LLC) prevents the voltage dropping under load. On some motherboards if you set a voltage of say 1.3V in bios without any LLC then it would drop to 1.2V under load. Which obviously affects stability cause under load is when you need vcore. Raising the LLC level counter acts this but it can go to far, if you LLC is too high you could set a voltage of 1.3v and find under load that voltage spikes to something ridiculous like 1.45v.

For your motherboard it is listed as Vdroop control. You'll have to play around to find the right balance.

The only options i seem to get here are AUTO and Low Vdroop.... Lol droop...... that makes me snigger :D
 
Yes i will add another fan to the front at the bottom. Ive got her stable at 1.28 at 4.2Ghz so happy with that at the moment. Temps are ok if not a little high but i know thats because ive gone for quiet over cooling.

Thanks all
