This. You need more cooling surface exposed to more fresh air. I think people are wasting money on upgraded coolers. You need more surface area...meaning more coolers.
I run into this in the E46 M3 community. People install an aftermarket cooler replacing an old, beat up OEM cooler...of course it works better! I lowered my temps by installing a 2nd cooler in series.
