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?

A blonde got stuck in her cute Mercedes Benz and cannot start it.
Another blonde pulls over to help friend and asking if she's wiped out headlights, bumper and dashboard.

That makes ZERO sense, czarivey

Check the cabling and back to the factory..

Try without playing music.  If it happens then, turn off, disconnect inputs.

If your amp is DC coupled, an upstream DC bias will cause these issues as well.

How are you measuring the amp's output? 30 watts continuous using a 100wpc amp is going to create a heavy thermal load. You'll want to have the amp looked at but you might just be driving the poor thing too hard?
