Block Eruptor USB or Blades are a better deal than this.

Lets do some math.

Block Eruptor USB: 2BTC minimum
Blades : 50BTC

Lancelot, lets say 300$ on average. Gox say 127$, so 2,38BTC. The group price at the moment is 269, so 2,1BTC

Block Eruptor USB: 300MH/s --> 150mh/s per BTC
Blades: 10gh/s --> 200mh/s per BTC

Lancelot --> 169mh/s.


Blades are a better deal, Block eruptors probably not. And I doubt we are counting electricity in an ASICs vs. FPGA fight now, are we?

Oh, and in group manufacturing? 399/2,1 --> 191mh/s per BTC. Clear winner Lancelot.

Probably cheaper to buy new ones. Can someone find a good replacement on eBay?

Depends what the original CFM of the old fans was. I quite like the Arctic Cooling F range. F8 is 8cm, F12 is 12cm etc. They don't push loads of air though. Scythe make some of the highest performance pc fans but they can be very noisy.

i thought i read some where that they could report temps

Though correct me if im wrong Tongue

and if they can im sure if a couple of us donated to kano and ckolivas they would probably modify cgminer to accomodate the temp recording function.

I'll do it for free - coz I have one Tongue
Just I don't think they do and haven't seen it documented anywhere.

Thats Great Bud Cheesy

I Found where i read it XD
it in the user manual in BlackArrows first post in the other features bit

Code:
Board temperature monitoring.
PWM fan control and speed monitoring.
standard 6 or 9CM low speed(1200RPM) fan.
FPGA core temperature.

Im not sure if it means we can get temp monitoring or even fan control but i hope we can Cheesy

I dint think temperature is available outside the controller. And there's no pwm from my experience.

That would be the hardware, it would require an MCU update to access and report that information (if it is possible)

This just hit me.  Is the shipping quote (regardless if its $70 or not) for each board?  Placed an order for 20 units.. I wonder if I just dug myself a DHL grave.

As mentioned, the next version will just find them for you.
However, there is a compile error (regarding device locking) on the Mac that I've never had anyone (programmer) hang around in IRC to sort it out.
