Ambient temp ques
Hi,
I have amd 2600 oced to 200x11 vcore stock....my cpu stays relatively cool 32-36 C idle and 42 load.....my ambient however is always about the same as the cpu....after load my mobo gets to 42 c....can anyone explain y? thx |

Under 100% CPU load, case temp should not rise in a case with proper airflow. You want a minimum of one intake in the bottom front and one exhaust in the mid-rear of the case, excluding PS fans. |

Are you sure "ambient" isn't really a temp probe on the motherboard just under the CPU? Temps are notoriously unreliable to begin with, so it wouldn't be odd that the on-chip and under-chip temps are the same. Case temperature should be within 5C of ambient(room) temperature. Under 100% CPU load, case temp should not rise in a case with proper airflow. You want a minimum of one intake in the bottom front and one exhaust in the mid-rear of the case, excluding PS fans. Maybe. But it seems more reasonable to want your CPU, bridge chips, graphics chips, HDDs, and maybe a few other things in your case to stay cool enough to achieve the heat-related risk of premature failure that you want, traded off with the level of heat production (overclocking) you want (or can achieve). Get or build a temperature probe (e.g., the one reviewed at http://www.extensiontech.net/article...o/pstu/3.shtml), and improve your cooling features until the temps are OK at sustained full load. (Or you might even have different limits for sustained full load and shorter duration full load.) You could wind up with a relatively hot running case that's quieter. Of course, to achieve the max cooling of the CPU, you'll need to keep the max amount of air moving past it, with max noise. But if you're cooling needs were moderate and you did careful fan placement and ducting, you could allow your case temperatures to be quite high, and enjoy the reduced noise. You can find some reliability vs. temperature information if you look for it; I've forgotten where I saw some. But I suspect that many people are running their chips and cases much cooler (and noiser) than they need to. (I know I am. |
