== CPU cooling tests ==
FIXME [http://pages.sbcglobal.net/redelm/ Сpuburn] is an utility to burn your CPU as high as possible. It tests your system stability by checking how the CPU and the whole system is working under high temperatures. === Installation === For Fedora Core you can get the RPMS from [http://dag.wieers.com/packages/cpuburn/ DAG]. For Gentoo:<pre>emerge cpuburn</pre> For other systems: download tarball from the [http://pages.sbcglobal.net/redelm/ home page], untar and run. === Usage ===It is recommended to switch to single-user mode and remount all the partitions read-only, just in case of system hang. Run<pre>burnBX || echo $? &</pre>for at least 15 minutes. If you have more than one physical CPU, repeat the command. If nothing is happening withing 15-20 minutes, and your system is still responding, you can conclude the test is passed, and kill the process(es):<pre>killall -TERM burnBX</pre> You can also use burnMMX utility:<pre>burnMMX J || echo $? &</pre> Cpuburn author says burnMMX is not optimal for AMD processors; use burnBX if you have AMD.
