I7 3930k Cooling

[torchinq]

So I have a i7 3930k that idles at about 40 to 50c it is stock I have not overclocked it at all. A few days ago I hit 100% load on the processor was at 75c. I know that the temps are most likely safe for this cpu becuse of how much power it uses, but is there a way to make these tempratures lower? Btw the current cooler I am using is a Noctua NH-D14 SE 2011 and it tends to spin at around 600-800 rpm.

First and foremost, the heatsink you are using with the fans it came with is capable of better cooling. Check in the BIOS to see if you have some fan control options to allow the fan to ramp up when the CPU gets hot. On ASUS boards, this option is called Q-fan. Using this option, you can set your Noctua fans to max speed when the CPU > 55 degrees or so.

Then, if that is not enough, you can always upgrade to higher flow fans. Noctua fans are optimized for quiet and low flow situations.

Try the 1st thing, that way you don't have to spend any money. If that brings down the temps a bit, and you are happy with it, then don't bother with buying fans.

What is the temp when u are running Prime95 for 40min?

What is the temp when u are running Prime95 for 40min?

I havent ran it yet because I have been worried about it damaging my cpu because of the temps. Should I not worry about that and just run it?

Before you consider the heatsink assembly I would consider your thermal paste application. Did you apply it correctly? Did you apply it at all? Was the surface cleaned (use rubbing alchohol or a chempad) and dried prior to application?

Check those and then I would go from there.

yes as far as i know it was applied correctly. I used the line method to apply it and the surfaces were cleaned before.

Use one of those apps.

And if temp is getting in the 80+ degrees, than just exit

the P95 by clicking to exit the app and the temps will fall.


Coretemp:

i ran it for about 25 mins and it maxed out at about 77c on the hottest core and the rest were close behind but they were all above 70c

Q-Fan doesnt really make a difference for the most part I changed from Turbo to standard to manual and turbo seems to be the best but not by alot

Does the CPU fan go over 1200RPM's?

 

[torchinq]

Does the CPU fan go over 1200RPM's?

i used coretemp so i couldnt check that i dont think should i run it again with HW64?

 

[nikorr]

OK,

Use the HWMonitor:

[nikorr]

BTW, whats your mobo?

 

[torchinq]

BTW, whats your mobo?

its an ASUS Sabertooth X79

 

[nikorr]

Nice.

Do u have connected the CPU fan and CHA fan2?

 

[nikorr]

The RPM's, are they over 1200RPM?

 

[torchinq]

Nice.

Do u have connected the CPU fan and CHA fan2?

Yes I used the cpu fan connector on the mobo and the cpu_opt connector on the mobo. should i connect to cha fan 2 instead of cpu_opt and i dont know where to see my rpms for the heatsink fans on HW Monitor

 

[nikorr]

Try that CHA fan2.

 

[nikorr]

Do u see that under fans?

What are the max RPM of your fans ? Usually under Q-fan, you can specify a starting temperature and a threshold temperature at which your fans max out. You want to set this maxing out temperature as low as possible if your board supports this feature. Also, if you want an idea what your current heatsink+fans are capable of, disable Q-fan entirely (you can do this with ASUS Probe in windows, or directly in the BIOS menu). This will give you an idea what your current setup is capable of without upgrades of any type.

if i disable q-fan will the temps be lower or higher? and im pretty sure the max for the fans is either 1200 or 2000rpm and i have only really ever seen them spinning at a max of under 900rpm

okay i see now what is CPUTIN cause mine says that it is 128c and my heatsink fans spin at 750-850 rpm on full load

 

[nikorr]

Don't worry about, its misreading CPUTIN,

what is the CPU temp under the load when the RPM's are @ 850?

its is about 68c to 70c

try this, actually open up your case, and then put your hand on the heatsink pipes. Do they feel like they are really hot?

If they are not getting hot; then the heat is not getting into the heatsink.

If your bios allows, try just running fans at full voltage speed; just to get a point of data to understand if it will drop your temps.

I would suggest just redoing the Thermal grease anyway.

If you disable the Q-fan, the fan will max out its speed. Q-fan works by gradually ramping up fan speed with settings the user supplied. So, to figure out how low temperatures can get, disable Q-fan, and the fans should spin at max RPM.
