Man who came up with 92
They are really common, a lot of the GPUs use 92mm fans.

Yeah but mine is very low compared to yours and my other one. And it's also getting 1,000 hw errors

Seems Jalapenos do indeed vary quite a bit, here's a screenshot from mine:

Crazy, well i guess 1k is better but my other is nill.

Damn I got a big problem, 1000 hardware errors! http://imgur.com/dX8Hlnc

Ignore the rejects, I was testing p2pool

I have > 4K errors since last 12hrs or so Smiley

Possibly, sadly I didn't really test it before modding it. But the temp is great. I do remember the temp before was +10

Spooky, could this mean that a lot of the jalapenos will fail within a short timeframe?
Did you change the fan? Could that make any difference(normally it should not)?

Is it possible that the heatsink have been moved around or something like that, or that you have shorted something?

my 2 do not have a large variance.

stock cooling/case, running 24 hours straight, in a warm room (80F).  40C 41C, 3.0v 3.1v, 7.35Gh/s  7.23Gh/s, HW errors 64 122.

These were delivered about 1 week apart.  Hope the data helps you.

Looking at the source code, the MCU reads three different voltages: 3.3v, 1v, and PWR_MAIN (12v). The 3.3v is being fed to the MCU through a voltage divider (/2) and also with the 12v (except with a /10 divider). I wonder which of these voltages is cgminer trying to report.
You mean "looking at" cgminer's source code?  Somewhere there is the printf that outputs that metric, stored in a variable being fed the reference value upstream from there.  Given BFL's doc push of the last days, couldn't it be determined that way?



Yeah, I glanced at the BFLSC driver in cgminer yesterday and found the voltages but I didn't quite know what was going on there.

my jalapeno voltage varied with temp.

3.4v @ 44 C
3.1 v @ 30 C

No you can see MySpace if you look closely. I just upgraded to ega.

Help! I cut my finger and broke the fan. What size is the fan? !
80, 92 or 120mm. Just measure across one dimension, external edge to edge.

Yes I use this app on my vintage computer
Yeah, but that CRT isn't CGA, is it?  It looks like text-only to me.
