I cannot do this right now, until I replace my cooling fan. It was shutting down my computer when it overheated. Once I have my issues resolved I will try again.
Have you also tried hoovering the fan on your CPU? I had the same issue a couple of weeks ago and found my CPU looked disgusting! I took the nozzle of a hoover, removed the fan on the CPU and hoovered near the CPU itself. It was amazing! It's helped in the meantime until I can find a clever person who can fit my new fan...the connectors don't match anything I have!!!!
Also, I'm curious...what can't you do right now? I'm lacking the context of your thread and if curiosity killed the cat and satisfaction brought it back, revive poor kitty!!!!x
If this is on a windows pc You can use the power options (under control panel) to limit the maximum CPU frequency. My temps dropped nearly 40 degrees F by turning it down. I essentially throttled my 3.0GHz down to 2.3GHz on my AMD. On my Intel I set it to 99% which essentially allows it to run at its rated speed but does not allow it to kick in the Turbo clock.

OK, I have to reinstall it to try it again. I have an i7 processor 2.8GHz, Windows 7, and 8GB ram. I had no problem in GPU mode, except for the fan issue. Thank you.
A lot of people over look this feature. It is usually unnecessary but the algorithm computing maxes out both my AMD (rated at 62 Degrees C) and my i7(rated at 100 degrees C). Not necessarily a problem except these WU's max them out for a prolonged period. By reducing the frequency you are essentially slowing down the system but (which makes the task take longer) but you are also lower the temperatures. The benefit is that you can restore the maximum potential as needed with one click. I think I might put up a tutorial just to alleviate some fears and potentially draw more people to the cause.
I believe there may be a setting to change how much of your processor or gpu F@H can use. Not sure where though as I'm not very familiar with the windows version. If you lower it by say 25% it should cut your temps down a good bit. Running the cpu / gpu at 100% as opposed to even 90% can really raise the temps a lot.
Good Tip. I went looking and found it under the Advanced Tab.
::EDIT:: After enabling the option, I did not see where this actually reduced the load on my processors for either my AMD or Intel. I still believe creating a Power Plan is the better approach.
