Is my NH-D14 Faulty? [nearly resolved] - Page 4

In my opinion an open case with the case fans disconnected does not resemble an open test bed,
I totally agree with this. Even if you laid your case down on its side it still would not act like a bench. The D14 is an ok cooler, but it wasnt better then my ultra120 extreme, unless silence is your thing.

I just ran the tests 1nst1nct1ve told me to run. I first remounted my NH-D14 by following the manual and what 1nst1nct1ve said. For the tests my CPU was at 4.6GHz 1.365V and i ran Prime95 small FFTs.

I put my CPU under load without the NH-D14`s included fans and let the temps stabilize(ambient was 19-20*C). I touched the heatpipes and they were all hot and about the same temp. I only put my CPU under load for about 8min because the temps were too high to keep running. The temps were 74 82 81 79 when the test started(load 100%), and 89 95 95 92 when it ended. The average for each core was 84.85 91.64 90.69 88.31.

So compared to the stock cooler, the NH-D14 without fans(passive) is better(it could also be my comp case). With stock at 4.6GHz 1.34V 19*C ambient, i hit 97*C on my hottest core within a few min, so Realtemp shutdown my computer.

For the second test i installed the fans, ran Prime95 for 30min exactly, and my ambient was 20*C throughout testing. My temps were much lower, so the fans arent faulty(i already knew this). The temps were 61 67 66 65 when the test started, and 67 73 70 69 when it ended. The average for each core was 66.61 73.32 70.88 70.19. after the 30min i opened the case and touch the heatpipes while still under load. They weren't hot like the first test with no fans, and they weren't noticeable warm either. They felt kinda cool, as in they didn't warm up my finger or cool it down.

I didnt bother with the Y splitter test, since i really doubt that it will lower my temps more than 1*C. All it does is lower the fans RPM a bit, and they are already running within their rated RPM.

Edit: After putting it under load for a bit longer, i touched the heatpipes again and they felt a little bit warm. The temps were about 1*C higher, and ambient was 21*C.

I know it wont act like a test bench, but i was just trying to remove the case cooling factor.
Silence is definitely my thing when im on the net, but when im gaming or not in the room with my comp i dont mind more RPMs.

Edit2: After looking at this thread, i noticed that my NH-D14 is performing the same as a Hyper 212+ assuming ambient temps were around 20*C. Here is an example:
ASUS P67 P8P67 Pro 2600k L040B165 5.00GHz 1.34v Hyper 212+ 70C Load

Can someone take a look at the recent testing i did and give me their opinion?

Thats a though one man.
Seeing how the heatpipes were not of different temps, it means none of them are cracked and they are all taking the heat equally.
It also yielded better temps than the stock cooler even without fans, meaning it's doing it's job.

As for RMA, I highly doubt they will do one as it is giving you better temps than your stock cooler and as far as I know, that's all they guarantee.

If you already tried to reset it all a couple of times and you are doing a proper thermal paste application, I am at a bit of a loss here. I know some paste takes time to cure before it reaches ideal itemps, but I doubt that will make a 10C difference.

whenever you take off the heatsink (while you were resetting etc), is the bottom of it covered evenly with paste or is t blotchy or just in the center maybe?

Have you ever thought that maybe your 2600k has a crappy IHS and it's uneven? I just got finished lapping my Q6600 and it dropped the load down 10C, and my heatsink is still not flat completely.

Edit:

Look at another user's post from another thread. (They just posted this.)



^Noctua cooler. Keep his voltage in consideration with yours when comparing temps. With that in mind I don't see what's the matter. But then again that user's temps don't look so good(80's) but he is using IntelBurnTest which makes chips considerably hotter than Prime95.

I had an NH-D14 on a lapped CPU that got slightly worse results than the Cogage Tru-Spirit I had before. Upon checking the heatsink bottom with a straight edge, I found that it was actually concave (center deeper than the edges). In my opinion, this is a worse case scenario. I tried several different TIMs and reseated many times with no real change in results. I RMA'd the heatsink and took the 15% hit from newegg. I probably should have tried to get it deemed defective, but didn't. I then bought a Silver Arrow and actually saw some decent improvement in temps. The fact that I have a lapped CPU and the Silver Arrow allows much more pressure for mounting was a big selling point. If I were you, I'd check to make sure whether or not your heatsink is concave. If so, RMA that sucker.

How you can have a faulty heatsink, which is just a chunk of metal, is beyond my comprehension.
post #39 of 103
Do you have heatsink fans on it? If not Id suggest putting 2 sink fans on it and run push/pull. If that still dosnt work try using a fan that has a higher static pressure. You may have to look into higher static pressure aftermarket fans.

Air coolers depend on their heatpipes, which contain vapor that changes phase to liquid (Look it up on Wikipedia). If there is something wrong with the heatpipes you will get inferior results.

These problems have been showing up recently. Are they selling too many and losing quality control?
