Temp issue with 212 evo - Page 2

The Noctua runs at 1500RPM (100%, ~55CFM, 2.61mmH2O). Would the 2000RPM blademaster make such a big difference (i.e. cause the temp to drop significantly)? I'm also looking into doing push/pull - perhaps due to the case size this might optimize airflow a bit.

Also keep in mind that the front intakes, and back exhaust, were the wrong Noctua type as stated above. I ordered the fans from two shops, apparently I ordered the 'better' NF-F12 from one, and three NF-P12's (1300RPM max, ~54CFM, 1.68mmH2O) from the other store. One of the front intakes is 'blocked' by the drive bay, and with the static pressure of the wrong noctua that might be an issue. The other fans are not blocked.

ALSO where are you getting your temps From ?? I use Real Temp. my Gigabyte board shows higher temp in Bios than the real temp. and Ez tune is worthless IMO....so try a few temp programs out and see what they give you....

All temp information comes from the 'lm-sensors' package under linux. I will install Windows after I switch to push/pull and thoroughly clean the heatsink and cpu with alcohol to make sure the 'nice and lemony Akasa TIM Cleaner' didn't leave any weird residue. The bios temps are mostly similar to the temps lm-sensors show (lm-sensors is usually 3-4C lower) - which is weird to begin with (i.e. I heard that the bios usually has a higher temp due to it using cpu cycles and not being smart enough to do what real operating systems do).

Thanks guys, I appreciate the help smile.gif

the pea method works best on the 212 evo. By best I mean its the easiest and provides the same temps as the strip method... just a pea size right in the middle strap the block back on done.

Adding more than one fan to the 212 evo in my experience doesn't lower temps more than 1-2c so its not worth the noise/power.

lm-sensors is very accurate from my experience use it on my core i3 550 machine.

Thanks. Just reapplied thermal paste and reinstalled the cooler. Wrt the second fan, I'm hoping that it does help, or atleast it won't be much noisier than a very high rpm fan. We'll see if that helps at all when I receive it later today.

The only issue I have with lm-sensors is that I'm missing quite a bit of information, perhaps due to the chips used by Asus, but it won't even monitor fan speeds etc. It's just showing the cpu package and core temps, that's about it. The core temps are often much lower though, i.e. the highest temp of 80C+ (and then drops to anything between 76C - 81C) was measured for just a split second on only one of the cores, all other cores were about 6-7C lower than that during the linpack (problem size 30000) runs I did.

If adding a second fan to the 212 evo doesn't help, I might aswell add the fan to the top of the case as a second exhaust. In that case it'll be two intake on the front, one on the top back and one on the top of the case.

Oh well, maybe my chip just runs hotter haha.

I recommend using the Top fan as intake as well and have the top back as the only exhaust fan. Point is pushing as much fresh air as possible to the CPU cooler and creating positive pressure inside the case.

Just wondering, does anyone have experience with the Noctua NF-F12's? They are only 55CFM - would it be better to only use these (for high pressure) on the 212 evo but replace the case fans with something which has a higher CFM? Any recommendations for fans with 4-pin PWM plugs, higher CFM and aren't too noisy?

I've been thinking about doing that my self recently,.... i'd have 2x 120MM front intake, 1x120MM top intake, 1X120MM exhaust rear. I could put 2x 120MM on the top also. Im gonna have to try this soon lol.

side not I noticed side fans doesn't help me cool my tempest 210 at all

Just out of curiosity (couldn't wait for the new noctua's to arrive) I tested the push/pull with the included coolermaster fan. Highest temp during linpack was 78C. Still not very good I suppose, but I guess there's not much else I can do. Also, ambient temps are a bit lower now, so on idle I went from about 38C to 34/35C.

Only two things left I can test:

1) Add an intake on the top as suggested earlier
2) Replace the actual case fans with fans which push more air (the Noctua's are rated for 55CFM)

By the way, is it normal that I can move the heatsink on the 212 evo slightly after it being attached? The screws are in completely (and I made sure the little pin is in the notch), and I only noticed when applying some force while attaching the second fan.

haha asked this question my self the simple answer is yes, since it is sitting on top of a layer of goo lol.. try not to move it though once its been screwed down or ull move the paste too, won't matter if its just a bit but if u move it alot i'd re-paste

OK - so I'm in Windows now - can someone comment on the following screenshots? How are those temps?

Prime95 (In-place large FFTs) ->



IntelBurnTest (set to maximum memory) ->

playing d3 so cant rly look too much but under 70c i see whats ur vcore at ? i get 85-87c range w/ 1.280 @ 4.5
