Upset with my OC

3n3rg3ia · 14 Apr 2013 at 11:08

Hello and Good morning overclockers 2 days ago i builded my new pc and my plans was stable oc to maximize its performance.

My build is

cpu:fx-8350
mobo:asus m5a99x evo rev.2
cooler:noctua nh-d14 max rpm without the low noise adaptor that reduces the rpm.
psu:corsair cx750watt bronze 80+
ddr:ddr3 hyperx kingston 1600mhz 9-9-9-27 1.65v
vga:sapphire 7870 xt
case

verseer rx-i snow with currently 4 fans this week ill install another 2.

Ill give you a view of my current overclock and my settings.

Stable oc is 4.5ghz-1.45v according to OCCT 1 hour of testing. My temps with core temp 1.0 rc 5 showed up 65c max but most of the times it was stable 58-59c with prime it was 62c , when idle the temps are 16c.

My bios settings is multiplier 22.5
CPU/NB freq auto
HT freq auto
i have disable all the power saving options including the cpu config options all are disabled.
I have inserted manually the ddr timings and voltage.

I have a feeling that my temps with this bestial cooler are high or they seem ok?
i added like a tiny dot in the center of the cpu like 2 small rices and i installed the cooler.

Im rly upset cuz i see reviews that they get like 4.8ghz stable with air coolers, the noctua nh-d14 have been reported as equal as the h100 from corsair , i dont get why such high temps and such low oc.

Am i doing something wrong? is there anything that can improve my overclocking, im not so familiar with the UEFI bios im not sure what to change and what not, i rly need some help to improve my overclock and be happy with my new build.

Thanks for reading and i hope you can help me.

Jim from Greece.

If you're getting temps that seem higher than they should be, you might want to make sure your cooler is mounted properly and you applied the thermal paste correctly.

Just use a small (pea sized) blob in the middle of your CPU when applying the cooler.

How hot is the air going into your D14 after a few minutes? In other words is your case cooling properly? Remember your cooler can only do a good job if the air it is getting is close to room temperature. If the cooler is getting air 10c hotter than your room than your CPU will be 10c hotter too. I use a cheap indoor/outdoor wired remote digital thermometer.. or similar terrarium thermometer to monitor the air temp 30-50mm in front of cooler intake. You want your cooler intake air temp to be within a few degrees of your room them.

If you have a tube of TIM take your cooler off and see if you got a good seat. If you did it rightthan do it again the same way. If you didn't than do it right, than do it right this time.

Thanks doyll for the reply,

My room temp is 25-28c and there are 2 fans at the moment that pushing air into the case , one fan in bottom side of the case that pushes the air forward of the intake cooler of noctua and one fan in the front side of the case , the pull fans are one in the top side of the case and one in the back side where the noctua fans pushing the hot air. when i place my hand in the back side fan i feel the warm air that gets pulled out of the cooler, so far i run prime95 for one hour and 30mins blend mode and my highest temp was 65c but most of the time its 60-62c.

I think nh-d14 sucks big time for vishera overclocks, i dont know what to do .

27c room so at a guess if some of the hot exhaust coming out of cooler is staying in case (and I guarantee some is) your air temp in case could easily be 35-39c. That means your D14 is sucking so bad it's cooling your CPU to 25c above the air temp it's being give to cool with.

25c above ambient is good cooling!

If you have a room fan, take the side off of your case and set your room fan so it's blowing toward your d-14 intake fan and see what your temps are.

i have 2 170x170x20mm fans that i bought but they didnt fit in the case cuz it should be 200x200x20mm , i ordered new 200x200 so they will arrive within this week, but ill try putting the 1 fan to push air in the cooler and ill update you in a while. Thanks a lot for the help you provide so far.

Don't thank me until we know your temps are better

You aren't doing anything wrong apart from stressing the CPU, anyone who says that Piledriver doesn't run hot are simply not maxing it out.

If AMD had the same temperature threshold as Intel (~90-100C) it wouldn't be a problem but these chips run in the 60's fully loaded and throttling issues occur at about ~70C. IMO the only way to overclock these chips without suffering (or being close to suffering) temperature or VRM throttling issues is to leave the default clock at 4ghz and use the turbo to go beyond that.

The only ones saying that Piledriver runs cool are generally those who are ignorant towards stability/stress testing, Piledriver is not that much better than Bulldozer aside from running ~500mhz faster at stock - so the temperature problems which before existed at 4ghz now occur at 4.5ghz.

Ok after some time testing with the new tuning my temps look like this , max temp now recorded from HWmonitor was 59c , thats 3c lower and most the times the temp is 56-58c at full load with prime95 blend test. That is indeed an improvement but not sure if its right to have my side panel open

i have to w8 for the new fans to arrive and maybe i want to believe that it will fix my temp problem. i dont know what else to do. But ur idea doyll was amazing, at least it made me realize how important it is for the cooler to get good air flow in order to maximize its potential and performance.

thumps up

*edit* the temp went to 63c for some seconds again, the thing that upsets me most is not that i lack the skill to overclock, is that in reviews they say that noctua nh-d14 has identical performance as h100 liquid cooling system from corsair, it maybe looses by 2-3celsius, and a guy on forums showed me screenshot with his fx-8350 to 4.5ghz with 43-47c, im really upset and dissapointed, no words, ill simply face the fact that i cant do overclock with this noctua and ill leave everything at stock settings, i dont know what else to do, screw all the reviews screw the overclock.

But i do appreciate the help and your interest to my matter and thanks a lot guys, i just have to face the facts im dealing with.

ill survive i guess.

Glad we got it down a few degrees.

Airflow not airblow. It's all about getting cool air to the cooler. Cooler is only as good as the air it gets.. and if you lower that air temp 4 or 5c you lower your CPU that same 4 or 5c.

I cool my 980 in old R2 with 3x 140mm intake fans.. 2x front and 1x bottom, no grills on front, bottom or back, filters on front and bottom feed air to Phanteks TC14PE w/2x TY-143's. Case fans are TY-140. All fans are PWM speed controlled by motherboard CPU fan socket using a PWM splitter with molex power from PSU. Idles at 24-28c@660-700rpm and stress's at 44-49c@1000-1050rpm. Case fans idle 700-740rpm and stress speed is 950-1000rpm. And it's quiet. Someday someone who know how to overclock i7 9xx will twist my arm and help me speed it up but for now it does everything I want with ease.

If you are any good at cutting construction paper (I use filing cabinet file folders for material), using a glue stick and spay painting with a rattle can you could make yourself a duct that goes from back of cooler to the exhaust fan/vent so all the hot air coming out of cooler goes out of case. Just let me know and I'll help you with it.

Not great pics but hope you can see how they work.
Out of case for top vent, second is in case between cooler and back.

Different system before final paint and fit.
