Nice overclocked with better temperature

I had managed to fitted a new Prolimatech Megahalems Rev B CPU Cooler with a new Scythe Kaze Jyuni 1900RPM Slip Stream 120mm Fan (just a single fan) and replaced all my antec 1200 case with 5 fans of these Fractal Design 120mm Silent Cooling Fan (3 at the front and 2 at the rear back)

Done prime95 with small FFTs stress and done linx stress all passed. The temperature was even much better than last time was 76C max, but this time, just 72C max with my room temperature of 23C. I wouldn't worry about the scythe kaze jyuni 1900RPM fan was too loud, because I set the bios fan as voltage on the cpu to control the fan as it will reach high speed fan during overclocked, but remain quiet when it reached idle speed (down to around mid 1350rpm to 1500rpm)

Here is the result of linx stress:

Here is the result of prime95 small ffts stress:

Overall, the Prolimatech Megahalems Rev B CPU Cooler is 4 degrees less than my old Noctua NH-U12P SE2 Dual Fan Quiet CPU Cooler with a push pull fans of 2 x Noctua NF-P12.

What you all think of this ?
 
Now fitted with new replacement Corsair H50-1 with a single fan (with corsair fan) blow out to the rear exhaust and using mx-3 thermal paste with a tiny small dot on the cpu processor. Amazing still at 65C max temperature for 4011.14Mhz overclocked and doing prime 95 small ffts stress for 10 hours. Meanwhile I had done linx stress at 25 times passed with problem size at 23118 and memory select at 4096 as temperature reached just 67C max.

Here is prime95 small ffts:

Here is linx stress (25 times passed):

Your temps will be a lot lower with this one.

Noctua NH D14

Here's the review.

So as you can see, when we take this Core i7 processor up towards 4 GHz we see that the temperatures are not at all an issue -- whatsoever. With the processors stressed we max out at less than 60 Degrees C -- at 4 GHz and a CPU voltage of 1.4 Volts. We average out the temperatures of the four CPU cores btw.

Mind you that we measure at a room temperature of 21 degrees C, in hot countries the ambient temperature obviously will also have a (negative) effect on overall cooling performance.

But since we only push 59 Degrees C .. my fingers got a little itchy, At this stage we where wondering if we'd be successful in overclocking the processor above 4 GHz, and so we did. We took it successfully and stable towards 4.3 GHz with 1.5 Volts pumped into the processor. The end result, with the processor cores stressed out 100%, is still stunning .. a temperature that is still hovering at acceptable levels at 70 Degrees C at 68 C / 154F.

I always wanted this cpu cooler Noctua NH D14 one day but I have to buy a new memory ram 6gb of 2000Mhz to ensure that won't block the memory ram slot as my current OCZ Reaper memory is no chance for this cpu cooler at the moment!

Where did you get this review from ?

On this review here: http://www.xbitlabs.com/articles/coolers/display/noctua-nh-d14_6.html#sect0 (why they use tjmax of 95C on i7 core 920 at 4ghz ?) Surely they cheated of lower temperature of this review ? If it was set at 100C on tjmax then the temperature will be lots higher.

Well it would be 5 degrees hotter...

Also would ideally need about 30-45 mins before the temps of the CPU will have levelled out and give the general max you are going to get, the 8 hours will only be for stability
