Amp keeps shutting off


I have the Schiit Vidar powering two 98db 1w/1m speakers. This thing will turn into fault mode so quick once turned up. Only using 4-10 watts per channel, it will turn off after 20min with a box fan blowing on it. I took the cover of the amp off, which I didn't want to do, and that didn't help at all (again with a box fan blowing on it). Once using anything above the 30 watt per channel range, the thing will last 1 minute before shutting off (although that 1 minute sounds really good). The amp is rated for 100w RMS per channel into 8 ohms. I'm not expecting it to actually sustain that rated power, but come on. Why isn't it at least sustaining 20 or 30 or even 10? Am I doing something wrong? Or am I out of luck?

After trying search all posts to find what speakers the OP has, I believe it’s the speakers, causing amp shutdown.
As every post the OP does says nothing about what speakers he has, mentions models of everything else, the only thing said by the OP about the speakers he has is that they are

" My speakers take 200w continuous with peaks to 800w or 1000w"

Something just don’t smell right here.

The Klipsch Epic CF 2. It’s a bright set of speakers that just need to be tamed. The spec sheet says as I wrote, 200w continuous, 800w peak. The Vidar has smoothed them out nicely, although I still have improvements to make. The speakers have never caused an amp to shutdown as the Vidar has in their 25 years of use. I don’t expect that to randomly change.
Contact Schiit. Your speakers are easy to drive and shouldn't be causing your amp to shut down. You're just going to get guesses here.

OK easy as pie to drive, go way back to my first post and do what I said.

I had a Schiit Vidar used as a monoblock go into protection mode when driving a Magnepan 1.7i speaker. Granted I was playing Jeff Beck loud. Still there is not enough headroom on that amp. Long since sold the Vidars. They were ultimately replaced by a pair of Bryston 28B3 monoblocks. No issues. Plenty of power and headroom. Contact Schiit for service.
