Fan dead spot?

[HappyCracker]

Okay, we all know that there are no fan blades in the middle of the fan because the motor is there. How bad of a thing is this because it seems like that middle spot would be sorta crucial. The only way around this I can think of is to get a blower. Anyone have thoughts on this?

the reason people worry of the dead spot is because it is situated right above the cpu die.
you can try getting YS Tech's TMD fan. it is able to make the dead spot smaller in the middle due to its unique design

actually, lots of HS's anticipate a deadzone in the center (like the whatchamacallit thermaltake p4 cooler). This really isn't much of a big deal. The weird edge driven fans have advantages and disadvantages. They vibrate a hell of a lot more than conventional fans too (though the startup sound is kickass)

Dont worry bro.
heres why:

Heatsink spreads the heat sufficiently enough to be exposed to the fan.
CPU die isnt exactly under the fan. Did you see that soclets are a tad wider (bigger than) CPU? So cpu die would sttill be somewhat away from the "dead" zone.
Unconventional fans are not super effective. its just marketing to give people what they think they need. Best solution - is a multifin (many, many THIN fins) COPPER heatsink with anyfan. Heck, i run my stock (updated version tho) AMD HS (Arctic silver) at 41 idle, 44 busy. And i only have 1 exchaust fan, and 2600+ CPU.

Thanks all, I was just curious about that. It seemed like it would matter, but once I thought about it, and especially with these new heatsinks (I have the AMD stock one for XP2500) I imagine the air is forced down between the fins anyway. By the way, this AMD sink isn't horrible at all, not the best for a good old fashioned OC, but it does its job.
