Hello,
I a bit confuse 'bout the cpu cooler (CM HYPER 212+) that i just install last 2 days. when i read many tech. online forums, it should reduce 'bout 7-10 degree Celsius... but mine only reduce down to 2 degrees Celsius.(From 40 degree to 38 degree on idle, when run Prime 95, its went up to 58 degrees and increasing but i stopped it before it fry my CPU) Below are my PC spec.

CPU: AMD Phenom II X4 955 BE
Mobo: Gigabyte GA-MA770T-UD3
CPU Cooler: CM HYPER 212+
RAM: Corsair gaming 4GB
Graphic card : Sapphire HD5650 pro
HDD: WD 640GB & WD 160GB
PSU: CM extreme 550W
Chassis: Thermaltake Dokker

Please help me regarding this issue because i have no idea what to do next.

1.Did you remove the plastic sticker on the heat pipe.
2.Did you use the thermal compound given or use a better one.
3.Did you use enough or too much thermal compound.
4.Did you clean the residue of the previous thermal compound.
5.Did you install your fan correctly.
6.Is your cpu cooler getting cool air and is there an exhaust fan for the hot air to escape the case.
7.Is the cpu cooler base secured properly?.

Because after I installed my 212 plus my idle temp from 45c is now 36c and during linx test at 100% cpu load max temp is only 65c before is 75-85c and only takes 2 minute to reach that temp but now can run 1hour also still 55-65c.

ambient temperature does affect the cpu temperature.

from stock heatsink to CM 212 and 2 degree drop - first thing that comes to mind is your casing airflow and ambient temperature.

if those are not good, don't even think about huge drop in operating temperature.

1. Yup, already removed it.
2. Use the given one.
3. From what i'm experienced before i think, i put enough thermal compound. (Is there any other methods to put the thermal compound for this CPU cooler ?)
4. Yup, clean it already.
5. I think so... after check it for few times.
6. my exhaust fan only at the back(arctic cooler F12 PWM pro). Intake air front (stock thermaltake fan come with chassis & side panel Cooler Master 120mm fan)
7. I think so... after check it for few times.

Now my temp run pretty high just for surfing the net is at 47 degree.

Added on May 5, 2011, 5:39 pmFrom what ur saying... i need to check ambient temperature first (coz its quite hot today).
So, I need to put more fans in side my chassis...??? I think i need to re-install my CPU cooler. Any suggestion for any good thermal compound....?? Coz need to buy one.

Thermal Compound Roundup - May 2011

Do u think dat I really need to re-intall the CPU cooler.... haih...~ Anyway, thx 4 da link... wat i heard dat "arctic" thermal paste is not bad....~

Actually there is ntg you can do except reinstall the cpu cooler since you are the one who nt satisfied with the temp . U using stock thermal paste ?

When I installed my 212 Plus I use CM Thermal Fusion 400 I don't trust the look of the given one.Look cheap

yup.... i'm using the one dat come together with the cooler....~

Whats your room temp?Maybe you put too much thermal compound....

I think, there somethin' wrong when I apply the thermal paste.... Look what I have found : http://benchmarkreviews.com/index.php?opti...=1&limitstart=5

Try and put 2 line of thermal compound on the cpu ...About 1 1/2 cm long and 1 cm apart.

You can also try better thermal compound I'm using CM Thermal Fusion 400

I did put the thermal paste on the processor... not on the heatsink or heatpipe.... But now, need to buy the paste cleaner also new thermal paste.... coz I already misplaced the stock thermal paste..... aiyahhhh.....

If you were my neighbour I sure give free my thermal paste that came with the 212+... ...

If you are planning to get a thermal compound get a better one but don't need so expensive maybe Rm20-30 will do just see it's review and there is a few people in LYN selling it just make sure there are a genuine seller...

searching for thermal paste now..... MX-4 or Silver 5 which one is better....???~

I'm curious, how did you "properly" clean your proc' old TIM? Don't tell me you use bunch of toilet paper to wipe it

wipes it with little alcohol.....??? is it okay if I do dat... teach me some coz i'm still a noob...~

Usually i did it like this:-

1) Wipe old TIM with toilet paper
2) Use few piece of facial cotton + nail polisher. Scrub the surface of the IHS until the cotton won't see any residue remain
3) Use alcohol swab to clean the residue from nail polisher chemical
4) Apply new TIM [not too much / little]
5) Mount the new heatsink properly [And again, don't do it half-a**ed.]

And as what bro' Goldfries said, make sure your airflow in the casing is good and ambient temperature also an issue. Get some time arranging your PSU cable properly

P/S : Since your using AMD proc', i strongly suggest you hold your proc' properly else you'll be crying having few bend or broken pins for your proc'

MX-4 will do.Not much different if use very high end thermal compound because you are just using 212+..
