Are temps high on my OC'ed 965 (with Corsair H50)?

Hi people,

I'm not sure about this but I believe that my CPU is having a cooling issue. Don't know what exactly... PS. I'm a bit new to OC'ing.

Here are my specs:

Phenom II X4 965 (OC details below)
G.Skill 2x2GB 1600MHz DDR3
Corsair H50 (with CM R4 fan - exhaust from top of case)
Asus M4A89GTD PRO/USB3 (with latest BIOS update)
Arctic Silver 5 TIM

And here's what my Phenom II X4 965BE is at:

225 x 17.0 - 3825MHz - 1.375v (set at manual through BIOS)

It's stable but the temps are a bit high IMO...

Oh: The intake rad fan is at max (2000RPM)... And I have another 2000RPM fan blowing perpendicular to the airflow of the exhaust...

I've tried re-seating the heatblock but I've had no luck... Any ideas?


Thanks in advance! :D

OMG I forgot to mention my main concern... The temp...

Umm... I get between 62 - 65c core temps... Idle is about 44c...

H50 is pretty much junk in most people's opinions...including mine. The H70 is somewhat better, but still poor performance vs. price.

What case? How do you have the airflow setup?

I have 2x 120mm CM R4's in the front as intakes... I've got 1x120mm intake in the back... To blow air past the rad... I've got a 140mm fan at the top (exhaust) next to the rad... But that's about it...

The H50/H70 have a high FPI (fin per inch) design on the radiator; it needs some pretty powerful fans in push/pull to make the most of its potential. Even then, it's still only about as good as most high-end air coolers in most situations.

What temps do you see at all stock settings (BIOS+benchmarks) vs. OC+benchmarks?

I'm curious as to what you are seeing between those 2. Also, approximate ambient temps?
March 7, 2011 3:37:54 PM

Well... I get about 48c at load on stock... And about 31c on idle... As for benchmarks... I haven't tried...

BTW, I've brought down the vCore down from 1.375v to 1.35625v and it seems stable (running Prime95)...

Ambient is around 25c...

Dropping your vcore will help; lower voltages are always better when it comes to OC'ing a chip. Your stock temps aren't too shabby; so likely your temps on OC are likely due to some higher-than-you'd-like voltages. Try getting the lowest stable settings and see where you end up. How long have you had the H50 on there? If it's been a few months or longer, make sure to dust it out with some canned air or an air compressor. Those high FPI rads get clogged with dust pretty quickly.

I'm willing to bet BIOS settings is likely the cause of your headaches.

I've brought the vCore to 1.35v... Stable and temps are about 62-63c... However I do want to get it lower as the safe AMD core temp is about 62c... And it has been said that the X4 965/955 become unstable at temps of 55c and upwards... So the lower, the better...

And I've had the H50 for about 7 months (since Aug), I blew out all the dust from the rad as well as the rest of the case...
March 7, 2011 3:52:38 PM

Oh you know how LLC when disabled is considered safer and often results in a drop in the vCore and temps? Well, I tried that... And it is unstable at all settings and voltages...

Well, I'm an Intel guy, don't know much about OC'ing AMD chips. You might ask in the CPU section of Overclocking for some details...?

Alright then... Will do...

Thank you for the help there rubix! :)

NP...I just think with everything we've gone over, it's not your cooler, but likely your BIOS settings. Once you get your BIOS OC figured out, swing back over if you still feel there are cooling issues.

Good luck!
