NH-C14 and Haswell?

post #1 of 4
Thread Starter 
Hi everyone, first post here so ill try to not screw anything up..

Has anyone used the NH-C14 with the new Haswell cpu's yet? I'm trying to find out if it would keep a modest overclock (something like 4.0-4.2) on the 4670k cool enough under load.

I found a lot of info on the D14 but not so much on the C14, so I was hoping someone could chime in.

Background info: I'm building my first computer with my dad (he's built them before) in August, so I'm getting all the info I can now so I don't do something dumb like buying a "k" series chip and a h87 board.

Ill be using a HAF XB case since I have an oddly shaped desk, and the NH-C14 would allow me to use a 200mm top exhaust fan. I could fit a Phantek TC14PE in the case but this would cancel out the option of the top exhaust fan.. And honestly I like the look of the C14 better.

I'm not looking to go crazy with overclocking the CPU but I would like to hit 4.0 or 4.2GHz without temps hitting the 90c mark. Ambiant temperature in summer can get up to 30c in my office as well.

Thanks in advance for any help!

What I found in overclocking my new 4770k is that at 4.7GHz, running old-style LinX, with core temps up to 91c, the air running through my NH-D14 was merely warm.

 

OTOH, when my i7 860 runs LinX at 4GHz and the cpu core temps are in the 70's, I could use the output as a room heater. In fact, back-to-back runs have warmed my basement a degree or two (and that's centigrade).

 

From this I conclude that at a certain temp, the IHS of my Haswell is acting like a thermal blanket. If it's not exactly holding the heat in, it's not exactly letting it out, either. So I pulled my NH-D14 and put on a Prolimatech Armageddon. It seems to work just as well.

 

In essence, any heatsink with a good bottom and lots of heatpipes (6x6mm, 4x8mm, etc.) will be OK for this cpu. If we want better, we will have to delid.

Do keep in mind it is much harder to keep the hot cooler exhaust from mixing with cool intake air with the C14 than with a tower cooler. wink.gif

Thanks for the insight!

It's sounding like the NH-C14 should be just fine for my purposes then thumb.gif

I was thinking that this would be the case if I were to use a normal tower type enclosure.. the hot air would be blowing against the side panel and not towards the exhaust fan like it would with a tower heat sink/fan combo.

However, since the MB is mounted parallel to the ground in the HAF XB the NH-C14 would be blowing the hot air up and out through the top mesh panel. I imagine it would become a bit more efficient using the top 200mm exhaust fan as well.. which is one of the reasons I am looking at this cooler. If I were to use the Phanteks or NH-D14 I'm sure it would be a little cooler, but I couldn't fit the top exhaust which would benefit the system as a whole and not just the CPU.

These were just my thoughts on the matter though.. more like an assumption of what should happen.. but I'm no expert.
