Here is how I have moved my fans, their are strapped with zip lock to the PCIe cables, temperature dropped with almost 20 degrees, now running under 40 degrees overclocked to 211, getting 485 GH/s. 231 and 251 are not working very good for my miner

Below are the images from OCT 4 VRMs with fans blowing about 45 Degree to the boards like Redbluebg doing. Running 231 with stock settings...

Based on these images I am not sure if adding heatsinks to VRMs be really beneficial. There is a danger of reducing the air flow in areas really needs cooling.

Does anyone know where is the temperature sensor for the ASICs?

What temps do you get on the chip itself? From the web interface and from your readings? And what hash rate do you get per board?
If there is a better way to cool the down side of the VRMs, we'd be able to achieve better performance, any ideas?
