|
 |
Hey guys!
I finally got around to fitting my Noctua NH-U12p cooler and everything went great. I used the included, and often rated better than AS-5, NT-H1 thermal paste and seated the cooler exactly as specified with zero issues. The problem is, my machine is now idling at a full 14c HOTTER than it was with the STOCK cooler.
On my stock cooler, pushing my E7200 at 3.4Ghz, I got 40-44c idle and 55-65c load. Now, with this new cooler - which is supposedly one of the best you can buy according to numerous reviews\benchmarks - the idle temperature is 51-56c and it loads at 70c.
I've got it running a single 120mm in a pull configuration, pulling cool air from the inside the case (fed by a front 120mm and a side 120mm intake) and pulling it over the heatsink and out towards the rear 120mm exhaust. So what's wrong with it? Does it REALLY need a burn-in period for the thermal paste to start working properly .. or is something fucked?
Thanks.

wtf that burn-in crap, if it shows current temps the way they are they will stay that way, in time more dust absorbtion will make it even hotter, so yeah something is fooked
either u applied too much thermal grease or fan speed is too low, there is also a possbility that radiator doesn't sit very tide, take your pick
considerably how crappy stock cooler really is noctua should perform much better

did u tried to put your stock cooler back to see if it still shows u same temps as it used to?
also how do u monitor your temps, bios or software?

I haven't put the stock cooler back yet, but I'm going to in the morning and I'm binning this expensive - but utterly fucking useless - paper weight.
As for checking temps, I use software and BIOS. Both agree, same temps. Idling right now at 48c. FORTY FUCKING EIGHT! IDLE!!
Fuck you Noctua.

Removed cooler, wiped paste clean, reapplied (again, just a dot as per instructions) and reseated the cooler. I even switched my 90mm top exhaust to an intake just to aid airflow. Same idle temp, but now it doesn't go over 60c load.
STILL not acceptable, not considering how "awesome111" this cooler is supposed to be.

if you used arctic silver then yes, you will need a burn in period. It takes a few days to a week for it to properly work itself in.
When your done with your computer, turn it off, play some games, turn it off, play some games turn it off, the heating up and cooling down helps align it's molecules. Their site says 200 hours for it to properly
From their site...

Important Reminder:
Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

You'll see your temps gradually fall. So more than likely, it's not your cooler.

I'd personally gone with zalman.

pretty much the same as the nwefrhew what the fuck ever name.
Have you tried using arctic silver? from the test comparison I read the shit only did 1 degree difference. Or at least give the stuff a week to burn in and properly seat itself, it may claim it doesn't need a time or anything but...it wouldn't hurt to try.

Best bet is to use a different TIM. My Q6600 idles at 30C even at 3.4Ghz so something is definitely wrong with your setup there.
Did you check to see if the base of the heatsink was machined well? And when you removed it the first time was it making good contact?

Mine idles at 30C as well.
Too bad he was banned. Lots of active participation here from him.

Hehe, it's not like he got permabanned, chill guys. Probaly a 24-hour ban or something.

Me? Naw, I usually get 1 or 2 bans a month. Comes with being so vocal and having strong opinions ^_^
Anyway, I still don't have a fucking clue as to why this cooler is performing so badly (I'm not going to rage about it anymore, done all my raging on my usual forum) but needless to say, it's broken. There is simply no other explanation for why it's not working -- or rather, not working as well as the stock cooler. The contact between the baseplate and the heatspreader is absolute. Rock solid stable on the motherboard, screwed and clamped in tighter than a nun's vagina - and exactly the right amount of TIM applied. I've tried the included, and oft-lauded, Noctua NH-T1 ... and I also tried some of my other AS-5. No joy. The cooler is absolutely ICE cold to the touch, so I guess that's what's wrong; it's just not drawing temps away from the CPU.
Currently idling at 45c and full loading (Orthos, 2hrs. Turn off for 30mins, back on and into Orthos for another 2hrs) at 65c. Almost exactly the same temps as my stock cooler.
The reason I bought this cooler was to further my clocking, so I tried that. Currently running at 3.4Ghz with 1.18v (love the E7200  ) and it ran, Orthos stable, at 3.8Ghz with 1.25v ... but temps were just shy of 77c load. NOT good for a 45nm chip.
.... so basically; I'm out of ideas guys. Truly out.
Here's my post from my regular forum;
| Quote: |
First few shots are from last night's application, following are from my subsequent cleaning of the HSF and CPU heatspreader (I used white spirits and soft tissue until they were gleaming) I then, again, followed the instructions to the letter and put more thermal paste on. Reseated the heatsink, twisted it back and forth as much as the mounting bracket would allow (barely 2 degrees either side) and screwed it down tight.
The contact with the CPU is absolute. The clamps are as tight as possible. The heat paste is done to the best of my ability and the directions given. Still the heatsink is absolutely ice-cold ... it's just not drawing heat from the heatspreader on the CPU.
Cheap, Taiwanese-made, bullshit.
I'm sticking to Zalman or AC in the future.

Even though the heatsink is still ice-cold, idle temps are now 36-39c (depending on whether or not I have the window open in the flat) and full load (Orthos and, hehe, playing UT99 at the same time) 55-56c.
I are confuzzled. How can the temps be lower when the heatsink isn't drawing them away from the chip itself?

BIOS, CoreTemp, Asus's Probe II and even Everest. All say the same.
It still doesn't explain why the heatsink, including baseplate in contact with CPU heatspreader, is ICE cold .. not even luke warm :-\

Why 60c? I've been over that many times on my stock cooler (and a few days ago, this POS wasn't cooling at all .. and load temp was 67c)
The thermal limit of the E7200 is 74.5c, which - so far - I haven't gone past.
I wanted to check the idle temps when the window was closed and now it's 40-41 with 57-59c full load. I want better, naturally, but it seems this burn-in period ISN'T a myth .. as temps have dropped 5-9c since last night.
(yet strangely enough, even though Intel list the thermal limit at 74.5c .. the TJMax is 100c. So having 65-70c load really shouldn't be that scary - right?)

By thermal limit you mean the Thermal Specification field in this page, right?
http://processorfinder.intel.com/details.aspx?sSpec=SLA3F#
If so, I think that you have nothing to worry about those temps on load. From what I've seen online, as long as you stay 15-20c away from the TJmax temperature, your CPU will live a long and healthy life.
For example, that E4400 I've linked to, tends to hit 70-75c on those hotter days (it's overclocked, too) and for 2 years now I haven't had a single problem... even if my idle temps are higher than usual (40-45c).

Aye, that's the one .. thanks! I knew it was "thermal" something, I just couldn't quite recall what it was.
There's so many horror stories about running the 45nm chips near, or at, 75c are - it was getting a bit worrisome. Cool, that means I can (after I've given the TIM a week or so to burn-in) start clocking my chip properly. I had it at 3.8Ghz with 1.25v and it was stable after 2hrs of Orthos .. but I didn't like the temps being near 70c load. I guess I don't have to worry about it as they've dropped now, and should continue to drop, as well as still being 30c from TJmax.
Besides, if it dies; it dies. I can always buy another one seeing as how the E7200 is dirt cheap now ^_^

How about you screw all this nonsense and buy a different heatsink. They are cheap and replaceable, I go through them like I do shoes.
