It didnt take Elenelen long to ramp right up to 500mhz with simple vrm heatsinks. Imagine what we could do if that cooling tower, thermal blanket, and that stupid bar were all gone, and replaced with an H2O cooler. the vrms, and any heatsink you put on them would then have excellent exposure to airflow.
If someone can mount an Corsair H80 on the chip and mount a push/pull fan configuration right on the side of the box you can literally bring the size of that box down to a small shoe box size. I've been using that Corsair H80 on my overclocked Intel 3930K processor for a while now and works great. It is a completely sealed system and keeps the processor cool at all times. If there is a will, there would be a way. The ASIC chips are larger in size, so making it work would take a good DIY'er.
Do you know how much heat the H80 can remove? I think those ASICs are about three times the power draw of your 3930k... it probably wont be enough.
