Bad news. Fitting my old gtx680 to do some Cinebench runs meant removing the fan I had over the NB/SB... Which had a disastrous affect on the NB temps. It hit 70c at idle (remember server hardware is meant to be in high airflow loud cases). Going to have to find an ITX/short GPU with Cuda, or I may consider a risky mod to replace the stock heatsinks themselves. Either way, no benchmarks for now... Sowwy.
