我一直有一些稳定性问题我 HTPC 最近. A reinstall didn’t help so I concluded it was hardware. Removing all non essentials didn’t help either so I figured it must be CPU, 内存或主板相关. 没有什么是超频或调整了其所有的相当近期的名牌包. 我压力测试的 CPU 和内存没有喧嚣-ING要么失败, but I continued to get occasional lockups and intermittent sluggish performance.
Now because this is a htpc, it is in a smallish case with low airflow. It has 2 120mm fans but they’re controlled based on CPU temp and are usually off due to low CPU usage combined with the huge Scythe Ninja heatsink. I knew the CPU wasn’t overheating but thought i’d check the gpu (A passive Radeon 5450) and hdd, which is in a suspension mounting which reduces the cooling it receives.
怎么然而无论硬盘和GPU都是勉强微温. 在这个过程中，我碰巧赶上我的手就相当可观芯片组散热器 (下面的照片中标记为“千兆字节”). 哎哟! I hadn’t realised that even with the substantial cooler the chipset required or expected some active cooling from the nearby CPU socket. 我没有粉丝DIR-ectly上 CPU 散热器 (你可以看到下面的) and the airflow over the chipset clearly wasn’t sufficient. 我原本粉丝排列吹空调出的情况下, but decided to try a small rearrangement — reversing them and fractionally increasing their minimum speed. Positive case pressure is generally 良好的实践中 任何路, and this way air is forced past the heatsink to exit the case. This small change seems to have done the trick.
Moral of the story: 最近的一些(ISH) 芯片组 (e.g. 英特尔系列 4 芯片组) 需要的reas上，能够气流 (或散热器升级 - E.G. 热右人力资源-05 这是现在在我店平列表). It may also be a good idea to upgrade the thermal goop supplied with a high quality compound. I recommend 集成电路 7 金刚石，如果你不能.
最后要注意的 - 在我的情况下，同伴南桥, 一个微小的“散热器”, (CEN-TER底部有图像) was only medium-warm and clearly doesn’t require any changes.
