So I’ve shown how it compares to the CPU-360 rev1.1, where the improvement comes from, two ways to improve it already, now it’s time to show how it compares to the best overall performing block of 2010, the EK Supreme HF. This isn’t the same block as last time (that one is in one of our pump testing loops), this is an all-nickel rev.2 with support for large compression fittings. The differences between my old Supreme HF and this Supreme HF Ni should be small, but it is important to note that the all-metal versions of the Supreme do induce a bigger bow, which should improve contact. Also, it’s important to stress that these results should not be compared with the results I’ve posted in previous reviews or on forums. Those tests were done with MX-2 and OCZ Freeze, two TIMs that are significantly less contact-dependent than Spire SilverGrease SP-457. The data below only shows half the performance picture, how it performs with a good (i.e., one that an enthusiast would actually use) TIM will be explored in the full review later.
So what does the data say? It says the verdict is still out on the CPU-370 vs. the EK Supreme HF Ni. Without knowing how these blocks will perform with enthusiast-level TIM, it’s hard to say which is better–they look to be really close. With Spire SilverGrease SP-457, the Supreme HF Ni comes out ahead, but it also makes better contact (according to my eyes). On top of that, I’ve already shown there’s two spots where the CPU-370’s performance can be improved by Koolance: injection plate and reverting to the CPU-360 rev1.1 base. Preliminarily, it looks the Supreme HF Ni is still a skosh ahead of the CPU-370.
