Every 30 seconds or so, my Jalapeno goes to 5900Mhps for a second then back up to 7300.... It only lasts for a fraction of a second.

Is this normal?  If not, any idea why it happens?

Could it be heat throttling? What temp is it reporting? Mine runs around 7450 with much less variation than you're reporting, at up to but usually below 45˚C. Also, what software and what pool are you using?

Bitminter, bitminter, and maybe... The heatsink seems to be a little tilted.  It runs at 53-54, but I think it can withstand much more than that.

That tilting looks weird. Get that sink off, put new thermal paste on the chips, and put the sink back. Better leave the side casing (both parts) and top plate off and have the fan blowing down on he sink, do the last only when you're really sure you want to run it without the side casing. Much better cooling and you halved the noise too. I get about 10-13 degree C. above ambient temp on a heavy overclocked jalapeno this way.

Alright.  I'm going to try doing that this weekend.

Also, is it OK if I leave the top plate on?  I like having the BFL logo, heh.

Looks like the screws are not evenly screwed to the same tightness. Temp is only 40C max for me with removed top and side casing

Ah, ok.  I took them out and put them back in, so that explains it.
