Spire TherMax II

Spire doesn't have a big brand-name presence in North America, at least not to the extent that SunbeamTech or SilenX enjoy. Regardless, the design of their TherMax II will be stikingly familiar to enthusiasts and overclockers who follow the products closely. Identical in core design to the Sunbeam Core Contact Freezer CR-CCTF and SilenX IXC-120HA2, the TherMax II (SP679S1-PCI) is practically the same product with a different fan. Like the Core Contact Freezer it closely imitates, the TherMax II is restricted to allow only one cooling fan to be attached onto the finsink assembly (the IXC-120HA2 nicely fits two).


Aside from its shared lineage, the TherMax II offers the effective Heat-pipe Direct Touch design, with four exposed copper 8mm heat-pipes rods in a "U" configuration ready to wick away the heat into 55 Aluminum fins. Looking up close at the TherMax II, there are no exposed heat-pipe ends at the top of the heatsink. This allows the SP679S1-PCI to fit inside some of the more slim mid-tower cases without rubbing the edges and possibly allowing the gas/liquid to escape from an opened rod. A well-designed high-pressure clip mounting system is used to secure the TherMax II onto the CPU without removing the motherboard.

Benchmark Reviews has tested the Spire TherMax II SP679S1-PCI with both the included cooling fan and a single Yate Loon D12SH-12 (88 CFM @ 40 dbA) for comparison.


The universally compatible TherMax II is the big brother of the original TherMax cooler innovation by Spire. Designed with four 8mm copper U shaped heat-pipes enclosed by fifty-five aluminum stacked Micro-fins. The heat-sink base is equipped with the latest Direct-Touch heat-pipe technology providing the optimal cooling configuration. The TherMax II fits nearly every processor available on the market today. Its cooling capacity ranges all the way from low end Micro-processors, up to today's hottest 150W dual-core processors. This cooler has it all! Equipped with Spire's signature UV-reactant BlueStar fan, this towering cooler is built to last!

Elements Thermal Conductance Research has not completed yet.
It lack the elements release rate into the air when heat stop provided to the element.
Nor has the chill factor when contacted with a reference element/cooper.

Hello It would be most helpfull of listing what motherboards would work with these based on experience and feedback. also the dimentions espially from the mount to under the 1st fin for many of us with denominator type memory have problems with clearance .
I would also like to mention I have a 770usb3 Gigabyte board and it is very disturbing that their engineers did not give a least 65mm from center of the cpu for the % is very high for coolers with 120mm fans
especially for over clockers such as myself. thank you and good work on your testing reports , Paul.
