We did our tests in Corsair Obsidian 800D case with three reference fans running at 900RPM (room temperature about 22°C). Our weapons of choice were EVGA’s X58 FTW3 motherboard and Core i7 930 CPU. The temperatures were measured at reference 2.9GHz as well as after our overclock (we pushed the CPU to 3.6GHz).
The heatsink measures (L)144mm X (W)50mm X (H)160.3mm, so you might experience difficulties when mounting it on certain motherboards that might have tall and/or wide chipset cooling solutions.
Armageddon’s slim design allows for mounting two 14cm fans, but we tested it with only one fan as you can see from the picture below. We’re talking about Thermalright’s TR-TY 140 fan (900~1300RPM) which ended up being enough for excellent Armageddon performance. The case’s rear panel houses a 14cm fan that pushes the air out, so we’ve got ourselves a neat push-pull setup here.
We used Prime95 (Small FFT) to put a 100% load on all Core i7 930’s cores, so bear in mind that we’re talking about a scenario that will most probably never happen. We measured temperatures on all four cores and put average values in the tables. We used Gelid’s GC Extreme paste.
After overclocking the CPU to 3.6MHz, Armageddon took the top spot. Indeed, it did so well that we’ll keep on using it as our reference point.
