Question regarding Noctua NH-D15 temperature

[sapped]

Hey guys, I've built a new gaming system recently and these are the specs:

Intel Core i7-4790K 4.0GHz Quad-Core Processor
ASRock Z97 EXTREME6 ATX LGA1150 Motherboard
G.Skill Trident X Series 8GB (2 x 4GB) DDR3-2400 Memory
Western Digital BLACK SERIES 1TB 3.5" 7200RPM Internal Hard Drive
Sapphire Radeon R9 290 4GB Tri-X Video Card
EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply
Fractal Design Define R5 ATX Mid Tower Case

It's running on stock cooler since I'm not thinking of overclocking just yet, however I've been having many issues with the CPU overheating lately,
therefore I'm thinking of upgrading to an aftermarket cooler. I have it set on the Noctua NH-D15, since my goal is to have the 4790k overclocked
to 4.7GHz in the future after I learned how.

Although since I live in a backwater country called australia, with the nearest computer store being 50 minutes drive away. I'm going to bring my
computer case there and let the store staff assemble it for me. (since I really don't know how and online delivery for the cooler isn't much cheaper
anyway)

What I'm wondering is, what sort of temperature should I expect with the benchmarks after the new cooler have been mounted? I've rang the store
and asked, they told me I can bring any benchmark and stress testing tool I want. You guys have any recommendations on what tool to use?

And what temperature range should I expect with the CPU (with non overclocked frequency) after the new cooler has been mounted by store staffs?
For the benchmark/stress testing utility that you're recommending that is, so any problems can be fixed on the spot in store.

Such as the idle/load/peak temps for the processor and also other components as well. Since it's better to know beforehand and let any problems to
be fixed in the store, than find something wrong and bring the whole case back afterwards.

Thanks for your time and appreciate any response!

Whatever it turns out to be, it should be about 2 to 3C better performance with this:

But you might want to eventually replace the fan.

Another member used a ducting enhancement with an H80 AiO cooler (and ducting is what I do with my NH-D14 and my own ACX cooler). At an overclock to 4.6 Ghz with his 4790K, some attention to airflow and case pressurization to force all the air in the case to exit through the CPU cooler and out the rear exhaust, his stress-test showed a maximum temperature of 70C.

I'm fairly sure I can match or beat that with my ACX configuration -- ducted to the rear exhaust. His "package power" estimate of thermal wattage was ~90W even with the overclock; my i7-2700K @ 4.7 shows ~140W. I get 71C with an Intel-Burn-Test "Maximum" setting.

Comparing the 4790K to my 2700K is a bit of an apples-vs-oranges comparison, though. I had been interested in the 4790K and the cooling requirements. Put it another way: If I used his cooler and installed it the same way, I'm confident it would prove my point about the ACX.

If you're set on the NH-D15, I'm ONLY GUESSING that you might expect closer to 74C to 80C or so @ 4.6 Ghz. And that's just a guess. The worst case in that assessment simply assumes you install the NH-D15 without any further attention to airflow, ducting, or any of it.

Here's another thought. The forum member with the H80 setup ran some performance benchmarks at the overclock setting, and compared it to the minimal overclock of the 4790K's turbo speed of 4.4. He said there weren't any performance gains for the OC'ing. And at 4.4Ghz, his load temperature was more like 57C.

4.7 is a pretty gnarly OC, especially if you want to be stable under IBT/Prime95 w/ AVX.

This has got a pretty good summary of how the NH-D15 will perform under load.

I would very seriously consider installing the cooler at home. The NH-D15 weighs almost a kilo, that's a lot of weight to have hanging on your MoBo, even with a backplate, if you're transporting your case and such by-car over 50 ish miles.

Also, it might be worth price-checking a few other coolers. In the US, the NH-D15 is usally ~90 USD, the Phanteks TC14PE is usually ~80 USD, the Scythe Mugen 4 is ~40-50 USD, and the ACFZ i30 can usually be found for ~35 USD. In dollars per cooling value, the ACFZ i30 is an easy recommendation. The real value of the Noctua is that it maximizes cooling and quietness at the same time, but the cooling performance alone is fairly marginal per dollar spent over the i30 and the mugen 4.

I threw in the EVGA ACX because both the reviews and I (also) prove that it bests the D14 by ~ 6C with 140W package power. The D15 only shows about 3C better performance than the D14. But -- you're right -- "quiet" is readily available with either D14 or D15 without "special attention" and some easy mods. Even so, the ACX frees up a lot of "space in the case."

All these tests depend on the thermal wattage of the test-bed, and it's always possible that the rank-ordering may change going up and down that wattage scale. But it's more likely at decently loaded test platforms that the rank-ordering between coolers will remain the same.

And -- yeah -- 4.7 is about the limit for that processor. More to the point and as I said, it doesn't seem to offer up benchmark increases above 4.4. Or -- that's decently reliable hearsay from other forum members.
