what i dont get though is that i use to be iunto radio control aircraft (the ducted fan ones) and so when i got into computer i had a bunch of spare duct jets around. natrully my e-vectra uses one. and yet why is this such big news? so hp had the smarts for inpeller+high powered motor + tunnel = cool server? what is so new and inovative about that?
EDT: i noticed somethign elese. hp says that the new impellers will force air out at the speed of leaf blowers but.... when you have a cooling system, you can have air moving at 400mph but the part that you are cooling still over heating. the reason? the air is moving to fast to transfer any heat. IMHO it is better to have a low speed fan, but moving lots of air over a large surface with a large heatsink.
I somewhat agree, air moving too fast doesn't warm enough to carry the [COLOR="Red"]heat[/COLOR] off.
However, moving more air is better than no air.
Hot CUP's might see more use of water cooling; i.e.: VW's bug was made to
run hotter to use fuel more efficiently ending the rear air cooled engine.
Time'll tell. Nice post, as always.
not exacly. if the air is moving to fast for heat transfer whats the point? on my custom made computer, the proc is a duron. AMD fans know that a duron runs EXTERMLY HOT. for cooling i am useing a HUGE heatsink with a very large potentally high powered turbine. the turbines max speed is 7,000RPM (faster then most hdds) right now, according to my status screen it is spinning at a brisk 5233 (well 5315 now, it changed) i also have a secound a third and a foruth fan in it. on is at the rear pushing air out. anothr is at the fround sucking air in and then another one is pushing air into the drive cages. just for fun one time (yesi had my finger on the powerstrip power switch just in case) i reved the turbine up to its semi max (6500) the temp started to get hottter so i reved it up all the way and the temp continued to climb, thus, i am right in say that high volocity moving air is not better then non moving air.
I wonder when those fans are available at the local electronics store. Of course, putting those in a desktop is just asking for a Janet Jackson accident...
I think the Deltas I use right now are enough. But I'll really look forward to those new fans...

i get mine from hobby town USA. the also sell salad fingers cpus!

The faster the air is moving, the more turbulent the airflow is at the boundary, and the more efficiently heat will transfer to the air. The air is not as warm coming out because the average amount of heat transferred into the air is smaller, due to the higher mass flow rate of the air. Faster air = better heat transfer. Unless you happen to create vortices, which will hamper heat transfer.
Check your airflow. Reverse or rearrange your fan configuration.
