English to Chinese Tech/Engineering IT (Information Technology) PC upgrades

Finally, avoid the mistake of using an inadequate or ill-fitting heat sink with your CPU. If your new CPU is substantially faster than your old one, it probably creates more heat, too. So unless you're already using a high-performance heat sink, consider treating heat-sink replacement as part of the upgrade process. You don't have to ***go all out with*** an expensive, complicated liquid-cooling system, but if you're spending $300 on a new CPU, spending $30 to $50 on a high-quality heat sink to protect that investment (and the rest of your PC) makes sense.
最后，要避免这个错误：使用的散热片散热效果不够好，或者与你的处理器不匹配。如果新处理器速度比旧处理器快得多，新处理器很可能也会产生更多的热量。所以，除非你已经在使用高性能的散热片，否则在处理器升级过程中要考虑更换散热片。你没必要***花大力气去购买***昂贵而复杂的液冷系统，但如果你花300美元买来了一颗新处理器，那么花30至50美元购买高质量的散热片，以保护处理器方面的这笔投入（和电脑的其余部件），实乃明智之举。
