My one blade has been running for days with out any heatsink on the back. The chips just have the little stick on ones. 40-50 ghs (solo mining) using ~60 watts. It seems the hashing speed depends on the clock/chip command. The blade is undervolted, still trying ti figure out how my one blade fried.
Can You share what vendor id device did You use and what version of cgminer? I have never reached more than 4GHs.

Quick update, here is the homemade stencil before etching. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FPZuPrZs.jpg%3F1&t=665&c=Zey12rLOB-E8Ig) And here is the soldered board after I fixed the minor issues. The TPS2044 has been bypassed. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2F795EYCu.jpg%3F1&t=665&c=9EK32d9tSR0E2g) The BOM for this one has been reduced to the following: ref | value | Qty | C1 | 680pF | 1 | C2 | 0,01µF | 1 | C3 | 100µF | 1 | C4 | 0,1µF | 1 | C5 | 10µF | 1 | C6,C7 | 33pF | 2 | C8 | 4,7µF | 1 | C9,C10 | 1µF | 2 | C11 | 0,1µF | 1 | CON1 | USB-MINI-B | 1 | D1,D2 | 4148 | 2 | IC1 | NE556 | 1 | IC2,IC3 | CP2102 | 2 | J1 | USB_2 | 1 | P1,P2 | CONN_8 | 2 | R1 | 1k | 1 | R2 | 10k | 1 | R3 | 1,5k | 1 | R4..R11 | 27 | 8 | R12..R15 | 15k | 4 | R16 | 2,2k | 1 | R17 | 15k | 1 | RV1 | 100k | 1 | U1,U2 | SN75240 | 2 | U3 | TUSB2036 | 1 | X1 | 6MHz | 1 |
The definitive board will use one or two CP2108 to allow up to 4 or 8 hashing units.

I'll try it again with my board instead of the cheap CP2102 from china. BTW, after reflowing, both CP2102 are detected correctly. I'll solder a second one tomorrow and test the chaining before sending them to CHAOSITEC and pekatete. I'll have a few spare boards I can sell for the price of the parts + shipping, if someone is interested. I ordered 10 PCB, and I currently have the components to make at least 6 boards.

They should be 15-20$ I'll check the price of the parts, but the fixed prototypes should be something like 10$. I just tested chaining, and it seems to work. Tomorrow, I'll test the PWM on the fan.

could you enlighten us on the resistor value you choose for this, and your cmd line?

Just tested the PWM control, and it works perfectly. Fan speed can now be adjusted with the trim pot. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Currently replacing the silabs driver with zadig to test the hashing

CP2108 will do it. and mounting holes should be added for the definitive boards. I've tested chaining, and it works as expected. The second board still have some issues with the USB port and the second cp2102 isn't working. Edit: I simply forgot to add a wire for the 5v supply since the TPS2044 isn't soldered. I now have 3 fully working boards.

It is not 42 at the end but 16 resp 12 GHs at pool stats.
