Overclocking
As cooling solutions do a better job of keeping the CPU at a lower temperature, it is reasonable to expect the overclocking capabilities of the CPU will increase. In each test of a cooler we measure the highest stable overclock of a standard X6800 processor under the following conditions:
CPU Multiplier: 14x (Stock 11x)
CPU voltage: 1.5875V
FSB Voltage: 1.30V
Memory Voltage: 2.20V
nForce SPP Voltage: 1.5V
nForce MCP Voltage: 1.7V
HT nForce SPP <-> MCP: Auto
Memory is set to Auto timings on the 680i and memory speed is linked to the FSB for the overclocking tests. This removes memory as any kind of impediment to the maximum stable overclock. Linked settings on the 680i are a 1066FSB to a DDR2 memory speed of DDR2-800. As FSB is raised the linked memory speed increases in proportion. The same processor is used in all cooling tests to ensure comparable results.
The Cooler Master Hyper 6+ reached 3.87 GHz, which is the second highest stable overclock yet reached on air cooling with this CPU. The CPU would boot at speeds of 3.9 GHz, but the system was not completely stable.
The Tuniq Tower 120 is still the fastest air CPU cooler we have tested so far, with the TEC/air hybrid Monsoon II at the top with this CPU at 3.96 GHz. The Hyper 6+did not outperform the Tuniq, but the performance was among the best measured with air coolers. The Cooler Master is clearly up to cooling and extending the overclock on your Core 2 Duo processor.

For straight air cooling? Not likely. The Tuniq 120 already stays pretty cool, and for the most part it's at the point where temperatures aren't the limiting factor in stuff like OC'ing. The only way to get better in terms of temperatures would be water or phase-change (or TEC). In terms of noise levels, it's already very quiet, but maybe an even larger HSF could do a bit better. Really, at this point the case will start to have as much of an impact as any further HSF changes.Now, if someone can come up with a way to make heatpipes work even better or something, we might see incremental improvements, but basically air cooling is pretty topped out I think. From here, we just want lower prices, lower noise, smaller, etc. but you can't usually get more than one of those at the same time.

Speaking of size, what is a good low profile cooler ? In my case (no pun intended), I'm using a Lian-Li PC-G50, PSU sits right over the CPU, and I would like to find a good low profile CPU cooler . . .katastrophe - Wednesday, February 14, 2007 - link
Shouldn't the graph on page 5 be titled as Mhz, or the values changed to reflect Ghz?Wesley Fink - Wednesday, February 14, 2007 - link
Yes. Corrected to be more consistent.thatdjsnow - Saturday, August 24, 2019 - link
Perfect! I'd been checking out this older blog at https://compareheatsinks.blogspot.com for a good heatsink comparison but it only has a few Cooler Masters! Womp Womp.. 😂This was much more helpful, thank you!
