On the box there was this sticker from noctua saying they have a bottleneck issue with supply and that's why they are sending the 2011 version but with all the trimmings of the normal version in addition to the 2011 version. So basicaly i got the best of both products
the 2011 PWM fans and the heatsink has mounted on it those little silicon things that the coolers stand on to reduce vibration aswell as all the mounting sets i could possibly need
That made me really happy after a short rage when i saw 2011 written on the box
Anyway ... i have it mounted on a 4670k with is OCd at 4.2 @ 1.200 v , Temps are spiky .. i understand that's how haswell works ? or did i do something wrong in the installation ? i did have to hold it down to fit those 2 spring loaded screws ... is that normal ? ... Anyway .. temps spike from 58 to 75 (full load) Aida 64 says the average on the most hottest core is 63.2 c (after 3h of aida 64).
So .. i am using a HF XM as a case... and i want to trick it out with noctua fans! I want the best results as possible...
These are the specs of the case http://www.coolermaster.com/product/Detail/case/mid-tower/haf-xm.html
What would you recommend ? what fans should i buy and mount them where ? and why ? i must admit i dono much about fans and i would like to learn! Like... what is the static pressure ? what is the spec that refers to it ? How important is CFM ?
Congratulations on getting all those goodies.
The Haswell chip has TIM between the CPU and the IHS, not solder. This means that when it makes more heat than the TIM can transmit, it gets hot in a hurry. It acts like a thermos bottle.
The key is to run it at an OC your system can handle. Since the highest heat comes from AVX2, and few pieces of software use AVX or AVX2, you will see spikes -- increases in temperature that move too quickly for and cooler to head off.
The solution is to download Linpack 11 (here) and turn off HT in BIOS, since HT slows Linpack down. Then you adapt your lininput_xeon64 file to run only the 25000 problem size. I set it to run 20 times. Then run that and check the core temps. I accept as good temps anything under 90c.
So, I run my 4770k at 4.3GHz, even though it is stable at 4.7GHz. I can run the old LinX with Linpack 9 at 4.7GHz, but LinX with Linpack 10, or LinX with Linpack 11 make it throttle -- temps spiking to 100c. So I am temp-limited, not stability-limited.
For true OC I think we will have to look at 3930k, which is soldered. You are OK for that because you have a 2011 NH-D14. If the 4930k is soldered (a preliminary look says it will be), then we will have an Ivy Bridge 2011 that will properly OC. I am holding out for the Haswell 6-core 2011 (5930k?) next year because I will have a purpose for it.
As I said, for 1150 or 2011, you will be set.
