 And also drop frequency of gpu to minimal before shutting it down. Such soft exists? I don't want to burn with my OCed gpu if something will go wrong while I'm sleeping.

Yes, I made on myself. First it will(depending on the miner, in my case it's cgminer) request via RPC to stop the offending thread. Should it fail, it will kill the miner altogether. It will then bench if the temp is still going above the threshold, in which case it will shutdown the PC.

It also detects FAN failure, and immediately shutdowns PC should it stop, or decrease below 700RPM.

Of course, it is for Windows only.

cgminer has built-in temperature and fan control.
I dont think it can shutdown the rig, but it will control fan speeds to maintain a desired temperature, decrease clocks automagically if temps exceed a given treshold and stop the GPU altogether if it exceeds another treshold.

fwiw, most GPUs auto-shutdown once they reach a particularly unsafe operating temperature - usually exactly @ 100*C.

Most people wouldn't want to go there. And CGminer's auto fan and clock control, didn't work for me.

No, they throttle, they dont shutdown.
And 100C is way above what I consider safe.

Then you didnt configure it right. It works perfectly. I use it on one rig to maintain maximum clock for a given noise level (fixed fan speed) and temperature. cgminer varies the clock to meet those, and will shut down the GPU when it cant. On my other rigs its set to vary fan speed to maintain temperatures at a fixed clock speed. And you can combine that. Its pretty awesome really

At least ASUS 5850s I have shutdown automatically. I had a particular box with poor airflow during summer, and whenever the primary card hit 100*C, it'd immediately shut off. There was no garbage, the miners acted normally -- the primary card (which was hottest) immediately spun down and stopped updating the monitor. I guess it could've just been the settings becoming screwy when it throttled down.

Ive had a reference 5850 that due to a bug got fed 1.65V for an hour or so. It kept mining during that time even though the GPU was throtteling at 100C and the VRMs were cooking at 130+C. I do know it was throttled because I got like 50 MH/s instead of 350+. No shutdown.  So I wouldnt count on it.

Sounds great, where I can get it?

Btw CGminer can be used as just temp control tool in addition to Phoenix?

Dont think so. But there are other reasons to consider it as your miner app, like failover pools.

cgminer supports phatk2? I'm getting best results with it. Sorry for noob question, but what's failover pools?

phatk2 is integrated in cgminer.
Failover pool is that you can define multiple pools. If one pool fails, for whatever reason, like when it comes under DDOS attack or whatever, cgminer switches to the next pool. Or you can even revert to solo mining if all your pools are down, just configure localhost as one of your pools.
