Noctua NH-U12P - okay with I5 overclocking?

Hey all,

I am about to upgrade to a 2500K i5 and intended on saving a bit of money by re-using my Noctua NH-U12P cooler. Will this still do a decent job with the newer chips?

It kept my Core2Duo E8500 under 50C at load at 4.2ghz so I am hoping it will still do a job for me with the 2500k. My case is the Antec 1200 so it should be pretty breezy in there :P.

Cheers!
 
Assuming that you have the SE2 model it will do a great job - if you have the original NH-U12P you may want to double check that it will fit or if there's an additional bracket/back plate that you can buy to make it compatible with an 1155 socket.
 
awesome, cheers for that. I already ordered the 1155 bracket from Noctua as i don't have the SE edition. I was just a bit worried after reading some comments about it being designed for older chips/hot spots and not being as effective for newer ones.

Is there any benefit at all in having a 2nd (exhaust) fan attached to the cooler (considering the 1200 case is loaded with fans already)?
 
It may not be as effective(sic) as the SE edition - but if attached securley it should still perform very well on top of a SB.

Push/pull does make a difference - but i would wait and see how the NH-U12P peforms without the additional fan if you already have very good airflow through your case.
 
I'd be interested to know what temps you get with this cooler/cpu/ combo please as i have the same.
 
I have yet to purchase the rest of the parts (need to shift my current E8500 rig). What sort of temps have you seen with 2500K at idle/load?

Varies greatly as it depends on the cooler in question, case airflow and the clock/voltage applied.

For a vague 'ball park figure' what cooler and clock/stock did you have in mind?
 
Sorry, I was just asking LtMatt what temps he has seen as he has the 2500K running at 4.6ghz with my cooler

I can't remember what it is at stock settings. But heres what im using atm.

This is about as far as im willing to push it i think. Think ive reached the limit. I have some IC Diamond paste coming, but at best that will only knock 2-3c off. (supposedly)

Under gaming temps stay under 60c.
 
ok my i5 2500k and asus p8p67 pro are arriving tomorrow, i will update you with temps sometime this week. ( i have bought a tube of IC Diamond also).

Nice. Looking forward to seeing how yours compare. I was a little dissapointed with diamonds results, on the first run it was no better than the mx2 it replaced.

On the second run two days later it had dropped temps 1c. I'll run it again tomorrow morning.

Interesting early results. I have the chip at 4.2Ghz (1.26 vcore) i'm getting idle from around 27-31C and a few minutes of Prime95 put some of the cores over 50C but still way under 60C.

It's actually cooler than my old Core2Duo. This IC Diamond seems to be working well!

I can't really compare to that.

Could you run 10 rounds of intel burn test on extreme and report back please? I find IBT adds an extra 10c ontop of what i get with prime.

Make sure to use Intel Burn Test 2.52.
 
I'm trying to be green atm. Have enabled high power saving on my mobo and rolled my i5 back to 4.0ghz at 1.16volts.

But i did just run a quick test @4.6 to see how the IC Diamond is settling in. I have to say, it seems to finally be working now its had a good few days to settle in.

Got bored waiting for the burn but managed 3 loops. 61C was the highest temp on one of the cores.

idles around 23-24C with offset enabled.

Any ideas why the burn test times are so much slower than yours? even though the speeds dont look that different?

I guess it takes longer because you have more memory.

Everything seems about right i suppose. I'd be interested to see what temps are like once you've done 10 runs as it takes a few to really heat it up.

Maybe next time try to run it on very high, that might speed things up a touch.

Looks like the original NH-U12P is more than capable of cooling a sandybridge - those are respectable temps at 4.2GHz.

And as LtMatt mentioned it's because you're utilising more memory in the test that the test is taking longer.

I'm pretty sure yours is cooling better than mine. That makes me a sad panda lol. Ill wait for you to post more though before i get to down on myself.
 
I'll have a look tonight at running complete burn test.

I am surprised at the temps tbh. So far the cores stay below 35C during Deus Ex. BF3 will be an interesting test though.

I don't really have a lot of interest in going higher than 4.2ghz (at the current time) as it is running rather nicely for what I need.

For reference, the rest of my system is :

Antec 1200 case,
Coolermaster 700W Silent Pro M,
Asus HD 5850 running at 5870 frequencies,
Asus P8P67 Pro rev. 3.1,
Asus Xonar DX,
8gb Kingston Genesis Hyper X RAM (9,9,9,24) @ 1600mhz,
Intel 2500K @ 4.2ghz (1.26v offset at -0.005)

I'll try running mine exactly the same as yours.

What level of load line calibration are you using? High or Medium or Auto?
