[UPDATE] Thinking about getting a NH-D14

post #1 of 20
Thread Starter 
Hello, I'm new here. I wasn't really sure where to post this, so I hope this is the right place.

Anyway, I just got done with my new PC build and I ended up buying a Zalman cnps 9900 max cpu cooler. I'm thinking about swaping it out for a Noctua NH-D14, but is it really worth the money or should I stick with the zalman?. I overclocked my system to 5ghz@1.440v, I just got done doing a stress test with IBT, and according to HWmonitor/CPUID my temps were averaging 75c - 80c. and would spike to 90ish. It still hasnt crashed yet, so im pretty happy with that, the temps just worry me. I dont plan on keeping this system at 5ghz at all times, I had it at 4.6ghz@1.3v and my temps were hovering around 60c - 65c, and I think I'll just keep my system there for everyday use.

Are these temps good? And will the Noctua NH-D14 drop my 5ghz, and 4.6ghz temps by a good margin? If it'll drop my 5ghz temps down by 10c, Im definitely going to buy it.

My system....

Cooler Master HAF X
Asus p8z68 v-pro/gen3
Intel 2700k 1155
zalman cnps 9900 max
8gig G. Skill RipjawsX


I just typed this post at 5ghz and it didnt crash, im happy.

Are these temps from prime 95 and real temp? I would run stress test for 12 hours to see if its stable.

For 4.6ghz, max temps should stay under 65C at full load, even after 12 hours with a NH-D14. 5ghz should be around the low to mid 70s.

As far as thermal efficiency you're only talking ~1C between the D-14 and CNPS 9900 so I would not recommend the change. Ambient room temp and airflow thru the case are important with a high OC and voltage.

Hopefully you only use a pea size quantity of TIM as too much TIM hurts the HSF performance.

Yeah, I did a lot of research before building my system. I only applied a pea size amount in the center of my CPU.

Thanks for your advice,

Stephen

The D14 is superior if you put a higher wattage load on the CPU. For example, at 4GHz with let's say 1.23v the difference will probably be minimal, but at 5GHz with 1.45v the difference will probably be around 10C or even more.

I just ran a quick 10 minute test with Real Temp, and Prime95. 4.6ghz@1.344v my max temp was 63C. Then I ran another test with IntelBurnTest and Real Temp, for just 20 seconds to see the difference, and my max temp was 66C.. So I'm not sure which one to go by, but it seems IBT stresses the cpu more, i don't know.

Edit: I just got a message saying "Warning! motherboard 76 centigrade", But all the temps look fine. weird.

IBT/LinX will generally put the temps up about 10C higher than prime95 will if you let it run for 5+ passes.

prime 95 usually shows its real max temps about 2 hours in and didn't seem to change much after that. 30 mins is still pretty good.

pretty sure mobo temp is measured at the northbridge. are you getting enough airflow just above your GPU?

I'm pretty sure the airflow is good, I have everything neatly tucked out of the way, and all wires coming off the mb are ziptied down. The air flow should be good, I'll double check when I get home.

I think I will go ahead and order the nh-d14. I keep thinking about it, and i kind of want it, so what the hell lol. I'll get it ordered and post back with my 5ghz results, on a 12 hr stress. I'm kinda scared to do it with this zalman cooler. My gf is wanting me to build her a comp now, which is perfectly fine with me, because I love this ****. So I think I'll just use the zalman on her comp.

Thanks again

Stephen
