I had a chance to test out some new TIM from Antec called Formula 7. I thought I'd share some quick air and dirty air cooling results I put together over the last few days. I tested it against the only other TIM I had on hand which was Artic Silver 5. The viscosity of the 2 compounds is very similar, but I was very surprised at the performance difference between them.
Test setup:
i7 980X
EVGA X58 Classified
Adata DDR3 2x2GB
Antec 1200 OC
Thermaltake FRIO aircooler, fans in push pull on high speed.
Ambient temps= 68F
I had never ran this CPU on air before, so I ran a small OC for 8 hours to get some heat into the mount and help spread the TIM out. After the initial burn in, I worked the CPU speed up to increase the load. Each mount ended up running about 2 days non-stop once the stable OC speed was found. Both tests were just a single mount, and the contact patern on disassembly showed good, even contact on both heatsink installs.

Artic Silver 5 8 hour burn in
Artic Silver 5 20 Prime95
Formula 7 application
Formula 7 contact pattern
Formula 7 8 hour burn in (notice the vcore difference)
Formula 7 20 hour Prime95
Conclusion:
While I'm not much of an aircooled overclocker, I sure can't ignore these kind of results. I was very surprised at the large temperature difference between the 2 compounds in the 20 hour Prime test. The 8 hour burn in results are a little skewed, I only now noticed I was feeding more vcore on the Formula 7 run, yet it still beat the AS5 by a few degrees. Without a doubt I'll be using Formula 7 instead of AS5.
