Ivy Bridge Overclock Temp with NH-D14

[stryker_cs87]

Good day,

I need to ask regarding my oc temp using Noctua NH-D14 cooler. My rig consist of i5-3570K (4.3ghz) and Gigabyte Z77X-D3H.

My OC,Vcore(stock is 1.19v) and Prime95 temp as per below,

3.8ghz/1.15v/55-65 celcius
4.0ghz/1.15v/60-70 celcius
4.2ghz/1.25v/70-85 celcius
4.3ghz/1.25v/85-95 celcius

Is seems that I can't oc any further due to temp already exceeding 80 degree on prime95, and the vcore already require 1.25 for only 4.3ghz speed.

I notice most people with same rig as mine can easily oc to 4.3ghz to 4.5ghz with same/lesser vcore and much lower temp with their NH-D14.

Is it that I got bad chip or is it something wrong with my NH-d14. I'm using Thermaltake Mark 1 Chaser full tower casing and I can assure the airflow condition is good with lots of fan,

Intake fan : 200mm x 200mm : 2 units
120mm x 120 mm : 1 unit

Outtake fan : 200mm x 200mm : 2 units
140mm x 140 mm : 1 unit

Sorry for the bad english, appreciate any advice given from you guys, thanks.

You know how to apply thermal paste properly right? That can make or break a good overclock.
When you installed the NH-D14, was it in contact with the CPU heatspreader at all times, or did it pop up at times? That creates tiny air bubbles, and will kill your temperatures as well.

When i'm purchase hte cpu, the shop people who the one that install the cooler and the thermal paste. I'm not familiar with applying the thermal paste but i can try learn the method first, will looking to it now, thanks

Basically all you need is a tiny blob in the center of the cpu (no less than a grain of rice and no more than a pea size), then install the NH-D14. It's a good idea to remove the fans from the cooler before doing this as well, they are easy to mount back on.

Also I highly recommend using the paste that came with the cooler, it's top quality.


It might take a few tries. It's ok if the heatsink "slides" a little bit, but if it loses contact with the heatspreader you need to clean the cpu and heatsink of any and all thermal paste and re-apply.

Hi,

Already finished clean the old thermal paste and put the new one on the heat sink based on method above.

Below are the temp. observed,

3.8ghz/1.15v/55-65 celcius
4.0ghz/1.15v/60-70 celcius
4.2ghz/1.25v/70-80 celcius
4.3ghz/1.25v/70-80 celcius

Still high for the temperature but at 4.3ghz the temp manage to stay around 70-80 celcius compare to previous (85-95 celcius)

Well, at least still able to reduce the temp at 4.3ghz and learned how to replace thermal paste by myself.

Thanks bouncedk for the advice.
