I had an old burnt up bfl jalapeno, so I took the heat sink fan combo and mounted it onto a GS stick. I also had some stick on heat sinks from the s1s and put them on the back side of the pcb for a little extra cooling. OC is at 400 right now and running smooth for a few hours with 0 hw errors, I will have to mod my usb hub to get any higher clocks but this baby stays cool. I usually see 22 to 28 ghs. This baby will be pushed to the max and hopefully survive, I do have plans of getting a few more and doing other odd ball cooling and OC.
