I remember asking this a while ago, but I lost the post among many others. Someone pointed out that only a single specific brand made an CPU cooler with contacts that actually fully covered the IHS on the CPU. Which brand was this?
The arctic cooler does an amazing job for the price.
I'm not sure that is true any more, but I suspect they were talking about the Noctua NH-U14S TR4. The upcoming Wraithripper cooler will surely have a full sized contact area as well.
I would recommend the NZXT Kraken X62
doesn't fully cover the ihs tho.
