The idle temperatures were a bit disappointing. It was a bit warmer than most at idle but it did perform well under load. It is beginning to be more and more difficult to compare case thermal performance as it seems most companies have nailed down what works and what doesn’t. Only the outliers really stand out anymore and if it fits somewhere in between the lowest and highest it generally goes unnoticed. The HAF XM gets its moment in the spot light for the CPU load temperature. Showing up on the low end is rather impressive compared to the other cases listed. I’m happy to see this even if the chipset on the other hand is a little toasty. However, the only cases that aren’t a bit warm on this graph are those with fans included on the side. Perhaps adding a couple of fans would help? Overall, it’s all good.
