That can be a fine case, but not with stock fans. This is what I did with my NZXT Beta Evo, which is similar to your case:



Ignore that bottom fan. I had to cut a hole to put it in.

At the top, the front position has a 140mm intake fan and the rear position is covered. With the side fan in position and (this is important) with the back grill cut out and no fan there, I get better cooling with my case buttoned up than with the side door off.

OK, so you can't spend more money. You can remove every electronic thing from your case, cut out that rear grill with side cutters (I did it that way) and file down the cut ends. Vacuum the case and wipe any metal filings out of it. Then put it back together.

With the back open, your NH-D14 will be your case exhaust (look at item 2 in my sig). Now take the fan that used to be in the rear and put it in front. Test the temps. Take the side fan and put it on top as intake (close off the rear fan position). Test the temps. Try various combinations and test the temps.

The basic principal is not to achieve front-to-back, bottom-to-top case airflow, but to present the freshest, coolest air to your D14. A heatsink cannot cool warm air.

Thanks so much! I already added the old fan from my arctic freezer, but I have a feeling I'm going to cut off the 80mm fan on the intel stock cooler (Who likes stock coolers, anyways?) and Jerry rig it somewhere

So after some work, I'm just barely grazing 80 right now, which is still hotter than I'd like. Before I start cutting pieces off my case, would you post some close up shots of the parts you removed? I'd really prefer to not TOTALLY destroy my case, but I figure you did a pretty good job of it, and I'd like to know what a properly-finished product looks like.

Also, by opening my window (I don't mind it a little chilly, and its ~38-40 out) I'm now idling in the mid-low 30s.

so you have OC@4800, hitting 80C in prime and you dont like it? real world temperatures cant be that high. that are perfect temperatures for that high OC.

No, I have it at 4.3, using less than 1.35 volts. To give you an idea, many users are able to run their 950s in the mid to low 70s, under load, with my cooler, with MORE volts. For an example, see:

http://www.overclock.net/intel-cpus/...age-temps.html

I'm beginning to wonder if my cooler is seated all the way...

The 4.80 run was a highly unstable screenshot suicide run, not a 24/7 stable operating frequency.

oh i see, i looked at your sig and thought that now you have 4800

what I always do is:
clean my CPU and cooler from old paste, clean it with some alcohol or something like that, put new paste on and use my credit card and spread paste all over the chip, that almost you see the chip itself, put on cooler.

Yeah- I think I'm going to use my old student ID card (I don't own a credit card, yet) and obviously, at the same time I'll be reseating my cooler. I'll go for a bit more pressure this time- I was being gentle with the mobo last time, but it's marketed as "tough"

I just had a similar problem, my cores weren`t cooled down equally,
so i riped my c-14 off and took a look, and boy I did much too much!
I thought i used about the same amout they said in the manual, but i was wrong.
It`s really a good idea to check it, there should be no problem, since noctua`s come with more than enough paste.

If all else fails, I'll stick it in the fridge

EDIT: After sufficiently cooling down my room, I'm 4 minutes into prime95, but I've already hit 76 on one of the cores

Since the CPU use is 100% the temps should go high relativly fast.
I heard that in some cases it`s possible to cool good till temp X (don`t remember the value) but over that temp the cooler (better the materÃ*al of the cooler) can`t transport
the heat efficently. But i don`t study chemestry...

ok so try to apply paste as I told you, and screw D14 until you can, it is safe and made by noctua like that
