If ya want a great way to test without a case , use this : HSPC Top Deck Tech Station , its open air , you can add as many fans as you like and it makes it really easy to test equipment , granted temp scores will be alot better ,but if your gonna take that baby above the horizon , who wants a case with bad airflow slowing ya down?

Just a thought!

What should I expect? Lower or same temps?

One more thing! Hyper 212+ has Blade Master 120 fan on it, but unfortunately those fans aren't avalible in Croatia. Can I put any 120mm fan on heatsink, or it has to be Blade Master 120?

Thanks!
Reviews do show that two fans helps on it.

Any 120mm fan can be installed on it. I'd recommend the Cooler Master R4.

You can still check the temperature but you can't see all the core temps.

Tried unlocking the extra cores and she did not post, cleared cmos and she is up and running again. Got her @ 4.0 w/ 1.425v using amd od idle @ 21C . It was worth the try, not too hard w/ the MSI board, but I cant complain since this cpu can oc better than my 940be and its much cooler. Will try to run a stability test to see how it fairs oc'd.

Hi guys! I am new on this...and sorry my english i am from argentina!!!
I have bought an AMD Phenom II x2 550BE with Gigabyte 785gt-ud3h rev1.0 MoBo.
When i try to unlock the extra cores, all seems great . I am running Windows 7 x64 and it started okei. The common applications runs okei.
But the system looks unstable. Por example when i open the IE it have some issues and PRIME95 DON´T WORK WHEN I UNLOCK 4 CORES.
I need help!! I tried raising up the voltage to +.050 and it run better but prime95 still not working.
Could any of you help me? what i have to try? Why prime95 doesn´t start? (with 2 cores works great. I tried with 3 cores and don´t work)
All parameters know are stock. What i have to try?

I tried BIOS f3 and know i am with F8..

AND SORRY MY ENGLISHHH AGAIN!

Thanks!!!

Unfortunately, your locked cores aren't stable and you can't do anything about it.
Lock them back and overclock your CPU, it has potential

It's almost impossible to find anything from Cooler Master here in Croatia.
Most of fans are from Scythe or Arctic Cooling.

But I have one 120mm Cooler Master fan which was preinstalled in my Cooler Master Elite 332 Case.
Lucky me! It is CM R4 in my case!
Or not.... I can't put it on heatsink beacause that fan doesn't have holes on both sides like the example...

hello. id just like to say that i have a successful unlock. unlocked my 550 (c3) to x4 and it primed stable at stock so im very happy about that. it posted up to 3.6 but would not stablize. i only have a cheapo $25 400w psu atm trying to power 2 opticals, 1 hdd, overclocked hd4770 and just hope that it just wasnt powerful enough (instead of unstable core 3&4). well i orded the xfx 650w psu and 2 500g f3's and CM 341 case to complete my budget beast. well see how it goes this monday when everything gets here. i hope it was just my psu holding me back. x/fingers.

PS: how should i overclock this system to ensure as much accuracy as possible w/o core temps? like so using HWMONITOR?:

test 1: x2 stock freq
TMPIN0:
CORE0:
CORE1:

test 2: x2 max freq
TMPIN0:
CORE0:
CORE1:

test 3: x4 stock freq
TMPIN0:

test 4: x4 max freq
TMPIN0:

does this seem right way to do it? i would use the differences of core temps and TMPIN0 (CPU temp for fan control i think right?) from the x2 stock/max tests to guestimate the core temps of the x4 stock/max tests?

I'm currently mulling buying a X2 555 BE and a Gigabyte board.

Am I ok to assume that if it can't unlock to quad core all mobos which support unlocking will allow me to try setting it to tri core? I've noticed that some motherboards seem capable of this but I'm unsure if they all are. (I have a preference for Gigabyte)
