Now it's hitting the hot period of the year it's time for all Ozzies to think about going away for some or all of the holidays. The question is, since it can hit 40°C+ while your away and there is no chance of turning the a/c on, do you risk leaving your crunchers going and potentially fry them - especially with GPU's pumping the heat out?

Since I hate turning my machines off, this got me thinking about CPU/GPU throttle so I did a bit of surfing on the interwebs and came across TThrottle. OH MY GIDDIE AUNT!

It may not do GPU throttling OK, but by choosing the right CPU temp (where you're happy with both the CPU and GPU temp) the CPU will be throttled resulting in the GPU being throttled indirectly. So far I've set my CPU to 63°C which is keeping my GPU at 80°C with a 25°C room temperature. The CPU is currently being throttled to ~95%.

Merry Christmas and a Happy Crunching New Year.

If you have a GPU that is capable of being run up that high, it should have come with some sort of tool for you to throttle it down yourself. Instead of running the core clock at say 900 mhz leaving it sitting at 75 degrees, run it at 850 mhz instead, leaving you sitting at 70 degrees...or 800 mhz just as an example. This should give you a bit of leeway as the day progresses and the temps start heating up. Yes you may lose a few minutes on a job but it's better than the alternative.

A gpu running at 0 mhz has a rather poor progress rate :D

Yes, but I want dynamic throttling so when the temperature is cool enough it does the maximum I want it to do but as the temperature increases passed the trigger point I set, it starts to throttle down. If it hits 0 MHz so be it. It's better than the card being fried.

Looks like the forecast is for hot weather (32°C to 36°C) while I'm away so it will be very useful.
