Help configuring SGminer - Able to restart an 'overheated' card???

[aso118]

I have a three GPU rig machine with tempcut off at 95.  Sometimes when the weather is really hot, the middle card, actually reaches 95 degrees.  It shuts off like it should, but then it never turns back on.  When I get home, its at ~40 degrees and is 'mining' at 0.000 khash/s. 

Is there some kind of flag or setting I can add to my config file to tell it to 'restart' once its cooled down?  It happens about twice a week in the summer - I'd hate to underclock the cards for just a few hot hours in the afternoon.

That is a result of the --temp-cutoff being default at 95 degrees. You may be able to use dynamic intensity and tuning based on temp with GPU settings (press the G key after cgminer/sgminer starts up).

I'm using 'auto-gpu' which helps reduce the clock speed, and seems to reduce the temperature, but sometimes that's still not enough.  I took a look in the GPU settings in SGminer, but I didn't see an option to turn on "auto-intensity."  There this a flag I could add to my config file?

Code:

{
"pools" : [
	{
		"url" : "stratum+tcp://us-east.multipool.us:11111",
		"user" : "xxx",
		"pass" : "xxx"

]

Dude if you are risking your actual graphic card I wouldn't risk it specially during summer, unless you know for certain the coin you are mining is going to blow up and that's impossible to know, on this scenareo then it's clear you have more chances at blowing up your GPU than you have to make any relevant gains.

What about try adding a fan to your rig to improve ventilation and decrease the GPU temp?
I don't think it is a good idea to have your card reaching 95 degrees twice a week.

one big fan should do the trick to lower those temperatures.

I actually have a big box fan on top of the rig.  It helps keep the card on the left and the right significantly cooler, but only drops the middle card a few degrees.

I agree.  I would ideally like to be able to put the "temp-cutoff" to 80 or 85 degrees, but this may cause the cards to turn off more frequently.  I wouldn't mind, but it would be nice if there was some way to 'restart' them after they cooled down

Edit:  If there isn't a 'restart miner' flag, is there some kind of 'auto-intensity' that it could drop the intensity until it cooled off?

What coins are you planing to mine with a single card?

Right now I'm mining 11x on a multipool.  Once it cools down I'll probably go to script-n (which uses a little more electric and generates a little more heat).
