you have the huge benefit of an electric clutched fan on your rig.
Can you easily tell when it comes on?
If so, that will help you to determine when having a block in there will help you and when it may harm you.
I'd go pretty aggressive during periods that I know the fan NEVER comes on.
My fan has the thermo "clutch", and stirs a whole lot of air even when cold. I took it off and run it all winter without a fan at all. I only get hot if I leave it in gear, in moderate temps, stuck in traffic.
I now have a pair of electrics that are not automated just yet.
