Topic: Got my JALAPENO today mining at 5.9 Gh/s with some tweaks - page 3. (Read 10454 times)
Skeptical post is skeptical.
Grats on actually receiving one!
What's the other BFL units in the picture, FPGA?
I noticed there are 5 HW errors in that photo. Might want to look into that.

The casing is indeed strange. More thought was given to style than function.
Perhaps they can team up with:

3. Flip fan around so that it is blowing down
Wait, so the fan was originally pulling air through the heatsink? BFL engineering excellence right there. 
Unfortunately no. You want to increase the air that moves over the entire surface of the heat sink. If you suck, the air will take the shortest path possible through the heat sink blades leaving some surface area with sub-optimal surface flow. If you blow air, it forces air into every nook and cranny of the heat sink increasing airflow over the entire surface. Proper heat sink blade design will prevent back-pressure and eddies.
An exception would be ducted heat sinks that have a clear input to output flow design, but that isn't what we have here.

ya, they drip ship bit by bit.. slowly .. Josh taking his sweat time
Dude, nice!!! more pics!!!
Purchased by rjk who sold his preorder to sadpandatech who then sold to me.
Did BFL ship the Jalapeno directly to you?
Or rjk had to do forward shipping ?
sadpandatech shipped it to me but I think he got it directly from BFL.
congrats

SO this was real product that was shipped not a sale given priority for a PR reason?? IOW - a trickle of jalepenos is actually leaving bfl still - which of course is great news..

Whoo hoo! Nice to see some shipped BFL product being put to good use! thought it was actually delivered customer order...was this unit purchased from a customer or some sort of dev., magazine writer, etc?
congrats nonetheless

The Jalapeno case doesn't allow for a lot of good air flow.
When running out of the box I was getting 5.8 - 5.9 when it first started mining and then dropped to 5.6-5.7 Gh/s after it warmed up. Soto increase air flow I did the following:
1. Take apart case
2. Flip top over and put on bottom
3. Flip fan around so that it is blowing down
4. Run screws through fan and plastic spacers into top which is now on bottom
5. Runs cooler and faster now
Getting 5.9 - 6.0 Gh/s now
Running on Cgminer 3.1.1
Thanks to Sadpandatech for selling me the thing and for the great suggestions.
